Gary Bowers: Commitment to the Dairy Industry Driven, yet Humble and Grateful

Discover how Gary Bowers’ passion and innovation transformed Lencrest Jerseys and impacted global dairy farming.

In the vast world of dairy farming, success often results from hard work, dedication, and innovation. Gary Bowers of Lencrest Jerseys stands out, not for seeking attention, but for his modesty and letting his work speak for itself. From his early days with Lorne Ella at Rock Ella Jerseys to managing Ferme Bovi-Lact for George Despatie to the start-up of Lencrest Jerseys with a mere 17.08 kgs/fat/day of milk quota to completing a recent succession transfer to his daughter Melissa Bowers and son-in-law Philip Aitken of Lencrest de la Vallee currently operating with more than 170 kgs/fat/day of milk quota, Gary’s story is a testament to the power of endurance and a genuine passion for the art, science and business of dairy farming. Throughout 40 years, Gary has made specific and significant contributions to various levels of industry organizations, including a transformative role on the Semex Alliance Board, thereby leaving an indelible mark on the industry.

From the Fields of Milby 

From a very young age, Gary’s passion for dairy cattle and the industry was kindled at his grandfather’s Guernsey farm in the Eastern Townships of Quebec. He fondly remembers helping his Dad and Grandpa and could easily recall the names of many cows in the barn. His most cherished memory was going to get the cows with his Nana. However, a day that remains etched in his memory is when his Grandpa’s farm was sold to what is now the Milby Golf Course, as his father chose a different career path when Gary was just six years old. These early experiences, though challenging, profoundly impacted Gary and fueled his determination to return to the dairy industry, which would shape his career. Gary often reflects that his passion for farming began at a young age. That true knowledge comes from a willingness to learn from others. In his teens, he gained a wealth of knowledge about farming and hard work from the Township’s Jersey breeders, including Ross Powell of Broadvista Jerseys, Warren Ross’s Ayshires, and Keith McDonald at Bonnyburn Jersey Farm.

Mentorship and Milestones  

Within a few years, Gary journeyed to Ontario, where he had significant experiences with Bruce Mode at Bonnie Brae Ayrshires. Gary regards Bruce as one of the most skilled cowmen he has ever known. Sean McMahon of Shamrock Farms, not only his father-in-law but also a mentor, played a pivotal role in Gary’s life. Gary was fortunate to have Sean in his life for 20 years before his unexpected passing in 2003. “Sean and I could talk for hours about pedigrees, bulls, and the industry’s needs. We didn’t always see eye to eye, but we always found common ground in our love for farming and the Jersey cow.”

At the Rock Ella Review Sale, Gary made his first Jersey purchase, Rich Valley M Gem Velvet Velvet. This sale marked the end of a memorable period spent living and working with Lorne and his family. During this time, Gary honed his cattle fitting abilities, animal healthcare, understanding of pedigrees, and fieldwork.

From Rock Ella to Ferme Bovi-Lact in Quebec, Gary then spent ten years managing a Jersey herd for owner George Despatie. In the early days at Bovi-Lact, Gary worked alongside Lloyd Fanjoy (Heaven Hill). “Lloyd was such a cowman, the person who really taught me how to feed and care for calves,” Gary noted. Gary’s leadership enabled Bovi-Lact to become a leader in Jersey circles, including Grand Champion Cow and Premier Exhibitor at the Royal Winter Fair in 1985. “I am also proud to have led 6 Grand Champions at the Royal Winter Fair for family and a friend.” During those years, Gary collaborated with international marketing firms to sell and transport premium Jersey cattle to Brazil, Colombia, and Argentina’s developing markets. Gary exhibited at numerous local dairy shows as he started to promote the Jersey breed in his home province of Quebec, hoping to grow the herd numbers within that province.

Recognition and Integrity in Judging

As an official judge for Jerseys and Holsteins, Gary’s extensive experience is a testament to his comprehensive understanding of the subject and unwavering honesty in dairy cow appraisal. Over time, Gary has established a reputation for being a straightforward and fair judge of the animals presented in the ring. He has judged numerous local, provincial, and national shows, including the Royal Jersey Show in Toronto and many International dairy shows in South Africa, Japan, Argentina, Brazil, Mexico, Uruguay, Columbia, and many state shows in the United States. Gary was called upon to judge colored breeds and Holsteins and could provide reasons in English and French.

Gary’s involvement as an Associate judge for Ayrshires at the World Dairy Expo in Madison, Wisconsin, with his close friend, Dave Wallace, was a watershed moment in his judging career. Walking on the colored shavings of such a well-known show cemented Gary’s name in the judging circles.

In Australia, The Royal Easter Show’s innovative requirement for judges to show ranks for the Supreme Champion classes on a board and offer thorough explanations for their selections deeply impacted Gary. He firmly believes in this transparent system as it ensures accountability while limiting political influence. Gary’s perspective is based on the ideals of clarity and responsibility. He thinks that every judge must be willing to freely explain and defend their findings to preserve the process’s integrity and create confidence among breeders and exhibitors. Gary has raised the bar in the world of dairy judging by constantly recognizing and rewarding animal excellence fairly and openly, reassuring the audience about the fairness of the industry.

Friendship & Sales Management 

Gary was also deeply involved in sales management for consignment sales like the Royal Jersey Sale and herd dispersals such as Norval Acres, Piedmont, and Shamrock. He worked closely with the late David “Butch” Crack, an infamous auctioneer, as well as a lifelong friend, the late Richard Caverly. “Richard was a humble, hardworking, and knowledgeable cowman. We traveled to many North and South American dairy shows together, a true friend and mentor to youth in agriculture. I think we shared a bond we shared: his commitment to youth, his exceptional work ethic, and his love of great cows.”

It cannot go without saying that Gary’s business mentorship came from the owner of Ferme Bovi-Lact, George Despatie. George was a successful businessman and visionary in Montreal, Quebec. George led the way for Gary in industry involvement and change through leadership as an influential Jersey Canada Board member and President in his own right. George’s business and financial insight guided Gary’s early years in business management. During his time with Ferme Bovi-Lact, Gary began as a director in Jersey, Quebec (span of 24 years) and Jersey, Canada (9 years), where he served as President from 2000-2001.

Roles Beyond Jerseys

Further to his roles on the Jersey Quebec and Jersey Canada Boards of Directors, Gary Bowers continued his involvement in the dairy cattle improvement industry with roles on many Boards of Directors and committees. These included the Quebec Dairy Breeds Council (CQRL-14 years), the CIAQ AI Centre (15 years), the Semex Alliance (14 years), the Canadian Dairy Network(10 years), and the Dairy Farmers of Canada (5 years). In early 2000, Gary played a key role in establishing the Multi-Breed Classification Program in 2005. This program offered by Holstein Canada is an essential tool in evaluating dairy cattle.

During his early tenure on the Semex Board, decisions were made to bring about a seismic change to the Semex management team with the engagement of Paul Larmer as the new CEO in 2007. This shift ushered in a period of advancement that indelibly impacted the worldwide AI business. Gary was a part of the board at the Semex Alliance, serving two terms as President, who worked diligently through introductions to genomics, sexed semen, IVF, and streamlined efficiencies in bull housing. Semex worked to become a leading solutions-based genetics company, a world leader with increased market share and a solid reputation for Canadian genetics.

“Gary’s contribution to Semex’s success is important, as he helped develop and support the goal of Semex being a worldwide leader. He embraced and promoted fact-based risk while highlighting opportunities for improvement. Gary never allowed himself or others to accept the status quo. Instead, he supported change where and when it was required. This earned him the tremendous trust and respect he deserves,” says Semex’s Paul Larmer.

Bowers’ position on the Canadian Dairy Network (CDN) board demonstrated his expertise in genetics and drive for improvement. Genomic evaluations for males and females were introduced during this time, and the Pro$ index was created. Near the end of Gary’s tenure, he laid the groundwork for the eventual merger of CDN, Can-West DHI, and Valacta, bringing DairyTrace into the fold under one umbrella known as Lactanet today.

His participation on the Dairy Farmers of Canada (DFC) board demonstrated his dedication to the dairy industry. Bowers was named to the ProThe action committee and worked on specifics for animal welfare, biosecurity, traceability, and environmental stewardship. This level of involvement was amongst breeders, processors, industry leaders, and politicians. The goal was always to move towards a sustainable Canadian dairy industry.

In 2024, Gary was honored to receive the Dairy Industry Distinction Award from Lactanet.

Breeding Strategy: Blending Tradition with Innovation

Gary Bowers’ breeding strategy combines conventional dairy excellence with cutting-edge genetic innovations. Over the years, he has expertly blended the traits of high-quality show cows with the economically advantageous features necessary for increased milk production. Early in his career, Gary concentrated on raising cows that could compete and stand out at shows. This emphasis on show-type cows resulted in several awards and a thorough grasp of what made a cow a top contender. Recognizing the changing needs of the dairy business, Gary modified his breeding approach in the early 2000s to focus on improved production and herd longevity. This change was necessary partly due to the shift in the live cattle market with BSE in 2003 and the demands for a financial balance sheet that had long-term stability. During this time, Gary also increased his active promotion of the Jersey breed within the province of Quebec through commercializing Jersey animals, whether Lencrest or others. Gary always wanted cows to do well and perform for others and often mentored and advised those new to the Jersey breed. This approach was suitable for both the breed and the domestic market. This grassroots work remains vital to Gary as the front line of the dairy industry is the dairy farm and its people.

Gary invested strategically in a Duncan Belle granddaughter, Piedmont Declo Belle EX94 22*, dam of Lencrest Blackstone and Lencrest On Time. Declo Belle produced 38 offspring for Lencrest. This brood cow was a long-standing #1LPI cow in Canada and Intermediate Champion at the Royal Winter Fair and All-Canadian Junior 3 in 2003.

Lencrest Cocopuf

Another key investment was the granddaughter of JIF Little Minnie EX96 4E 12*, a two-time Royal Champion. This granddaughter, Select-Scott Salty Cocochanel EX94, was also an All-Canadian Junior two-year-old. Descendants of Cocochanel have the biggest influence in the herd today, with names such as Lencrest Cocopuff EX93-3 E 4* and some of her sons including Lencrest Artemis, Lencrest Caspian, Lencrest Broadband-P and Lencrest Contour. Lencrest Cocopuff was an 18-time # 1 GLPI cow in Canada. Cocopuff’s granddaughters hold the current #1 GPA LPI position in Canada for heifers under nine months of age and the current #1, 2 & 6 position in Canada for heifers over nine months of age.

The investment in another maternal line of Responses Farren, Hauptre Blair Famous, stands out in today’s herd with Lencrest Premier Farren, dam of the bull Lencrest TobeFamous. 

Gary expressed the need for balanced breeding, production, and type, a total concept approach in which high genetic index, such as the LPI (Lifetime Performance Index) and Pro$ (a measure of genetic merit for profitability), are examined alongside robust type features. TODAY – of the Top 50 Jersey Heifers over nine months for GPA LPI – 38% of them are either of Lencrest prefix, sired by a Lencrest bull, or have a Lencrest maternal grand-sire.

Paving the Path to Technological Advancement

With the development of a succession plan, Gary knew the original home farm of Lencrest would not meet the needs for growth to a herd size that would match trends for viability in the growing dairy economy. A nearby farm with a greater quota base and building infrastructure that could support a shift to robotic milking without investing in brand-new facilities was acquired. Again, the key was to innovate and grow in the most efficient way possible for his family’s business needs. Gary Bowers has always been a visionary in the dairy sector, looking for ways to enhance efficiency and output via technical innovations.

Robotic milking systems are one of the most noteworthy technical advancements. Gary, Maureen, daughter Melissa, and son-in-law Phillip saw the need for change in their operation. They welcomed this new technology to ensure the long-term viability of their dairy operation. This technology, along with regular quota purchases, has allowed for the development of the herd size without extensive labor needs, all while improving efficiency in herd management, milk quality, and financials.

Phillip’s technological knowledge is critical for developing and maintaining the robotic systems and on-farm reporting. His experience with GPS systems and precision agricultural equipment has been essential.

Melissa’s expertise in genetics, on-farm technologies, and business brings innovation and continues to drive the Lencrest breeding program. These factors result in the ultimate and necessary goal of economic viability. This joint effort among family members demonstrates how adopting technology may result in substantial breakthroughs and operational success in contemporary dairy farming.

Words of Wisdom

Gary Bowers offers some wise words for young individuals entering the dairy sector. He argues that knowing the industry is vital. Gary elaborates, “It is important to know domestic markets and understand the global milk industry. My travels abroad helped me to understand not only elements linked to breeding and genetics but also to the global milk economy. You need to know where your milk’s going and be aware of the entire ecosystem that supports dairy farming.”

Financial knowledge is another critical component of success. Gary pushes for a good company strategy that includes thorough financial plans. He feels that understanding economic systems is essential to guaranteeing long-term profitability and resilience, particularly given the volatility of agricultural markets. “You have to be astute in business and know how to manage your finances, investments, and operational costs,” Gary tells The Bullvine.

Gary’s advice, however, places a significant emphasis on enthusiasm. “You need a genuine love for dairy farming to sustain the demanding workload and overcome inevitable challenges,” he says. This enthusiasm feeds everyday operations and promotes continual learning and innovation, assuring the farm’s growth and success.

Gary’s thoughts provide a road map for young individuals joining the dairy sector. He urges students to be well-rounded professionals equally comfortable with financial spreadsheets, milking systems, and cow comfort/care while cultivating a great passion for their work. “Without passion, the hours are too many, and the work is too hard,” he continues, emphasizing the significance of putting one’s heart into the operation and the sector.

The Bottom Line

Gary Bowers’ experience in the dairy business exemplifies the power of devotion, ingenuity, and an unwavering pursuit of improvement. Gary has continually exemplified what it means to lead by example, beginning on his grandfather’s Guernsey farm and culminating in his crucial role in modernizing industry boards of directors. Gary’s efforts for the Jersey cattle sector resonate across continents, demonstrating his worldwide significance. His foresight in using robotic milking and his approach to farming have taken Lencrest Jerseys to new heights, demonstrating the value of combining tradition and innovation. The Bowers Family’s ongoing dedication to dairy excellence exemplifies the qualities Gary exhibited — hard labor, creativity, and a genuine enthusiasm for the sector.

Through all these connected experiences within the dairy industry, Gary is mostly grateful for the people he has met and collaborated with, including industry professionals and the many hardworking dairy cattle breeders across the Canadian landscape and worldwide.

Heifer Shortage Crisis: Why Dairy Farmers Are Struggling Despite Soaring Milk Prices

Uncover the surprising reasons behind the heifer shortage hitting dairy farmers hard, even as milk prices soar. Will they be able to solve this issue and expand their herds? Find out more.

Milk prices are at their highest in years, but dairy producers face an unanticipated catastrophe. It feels like a contradiction. Despite good on-farm margins and lower feed costs, dairy farmers face a huge challenge: a severe shortage of heifers and young cows for future milk production. This shortfall is more than a mere inconvenience; it alters dairy producers’ plans and choices throughout the country. The market has been delivering a clear message: produce more milk. But what can farmers do when the appropriate livestock are not available? In the following parts, we’ll examine the causes of the heifer scarcity, its influence on the dairy business, and whether current high prices can reverse the situation.

MonthHeifers Sent to Beef Packinghouses (thousands)Average Price per Heifer ($)Milk Yield Trend (compared to previous year)
September 202328.62,950Stable
December 202325.43,000Stable
March 202423.13,200Slight Decrease
June 202421.13,300Decrease
July 202420.73,350Decrease

Economic Highs and the Surprising Heifer Dilemma: What’s Holding Dairy Farmers Back?

Dairy producers are enjoying some of the most favorable economic circumstances in years. Lower feed costs and predictable milk profits enable farmers to pay off debt and save for the future. This stability has arrived at a critical moment, providing a much-needed cushion against previous financial strains.

But it does not end there. The market is indicating that it’s time to increase the milk supply. The temptation to produce more milk is straightforward, with prices hovering around $20 per hundredweight. Farmers are prepared and eager to satisfy this demand, but a significant impediment is the heifer scarcity.

Scarcity Strikes: How the Heifer Shortage is Undermining Dairy’s Economic Boom

The heifer shortage has struck the dairy sector hard, challenging the momentum of recent economic highs. This shortfall has worsened since September when dairy companies looking to increase their herds encountered a shortage of heifers. The shortage caused them to rethink their strategy: fewer cows were transferred to beef packinghouses, and less productive milk cows were retained longer than usual.

This shift is evident in the stark numbers: from September 2023 to June 2024, dairy farmers sent 286,100 fewer milk cows to beef packinghouses than the previous year. Initially, this technique seemed practical since U.S. milk output stayed consistent throughout the autumn and winter. However, the consequences have now become apparent.

The most recent Milk Production report reveals milk yields at or below year-ago levels in two-thirds of the 24 central dairy states, including areas unaffected by exceptional weather circumstances. This pattern highlights heifers’ crucial role in maintaining and increasing milk output. The lack of heifers and the dependence on less productive cows are already noticeably lowering milk output, posing a challenge for farmers looking to capitalize on good economic circumstances.

Rising Heifer Prices Aren’t Just a Headline: The Operational Burden for Dairy Farmers

YearHeifer Price (per head)
2018$1,500
2019$1,750
2020$2,000
2021$2,200
2022$2,500
2023$2,800
2024$3,075

Rising heifer prices are more than just a headline; they are a significant issue for many in the dairy business. Last week, the top 25 springers sold for between $3,000 and $3,300 per head at the monthly auction in Pipestone, Minnesota. It wasn’t simply a regional increase; top-quality Holstein springers averaged $3,075 at the monthly video auction in Turlock, California. These statistics are startling when considering how they will affect your operation’s finances.

Imagine planning a herd expansion only to discover that heifers suddenly cost thousands more than expected. The financial hardship is confirmed. Higher heifer prices raise starting expenses, forcing many companies to reconsider their breeding strategy or postpone growth plans entirely. Although milk sales remain stable, rising expenditures make it difficult to invest for the future or pay off debt.

With beef prices high, many people turn to hybrid dairy-beef calves for a more immediate cash source. This technique provides a faster financial return but needs to address the long-term need of keeping a healthy milking herd. It’s a difficult decision: spend substantially now with uncertain future profits or capitalize on the present meat market for faster gains.

The problem is more than statistics; it is about planning for sustainability in a volatile business. Your ability to handle these complex dynamics will influence the future of your operations, so it is vital to be aware and adaptive.

Why Are Dairy Producers Leaning Towards Crossbred Dairy-Beef Calves? 

Why do dairy farmers choose crossbred beef calves over conventional dairy heifer ones? The solution rests in irresistible economic incentives. Crossbred calves may provide more immediate cash, frequently commanding $200 to $400 more than purebred Holsteins. This quick income is a game changer for dairy producers wanting to secure their finances in an ever-changing market.

However, the value of dairy heifers remains variable. Investing resources in growing replacement calves is a long-term risk, with no certainty that these heifers will be worth the high price when ready to join the milking herds. In contrast, revenue from beef calves is immediate and guaranteed, making it a less hazardous and more tempting choice for farmers. The quick financial gain from beef calves helps dairy producers navigate a volatile sector, maintaining a consistent revenue stream even when prices move.

Traditional Breeding Battles Modern Economics: A Minority’s Approach to Sustaining Heifer Supplies

Surprisingly, a small number of dairy farmers are adopting a more conventional strategy for breeding, focused on maintaining appropriate heifer headcounts to support their herds. These farmers recognize the long-term importance of a consistent supply of replacement heifers, even if it means preceding some immediate revenue from crossbred dairy beef calves. However, these changes are minor enough to reduce the overall heifer shortfall significantly. The financial incentives for generating crossbred calves are too appealing, causing most dairy producers to prefer quick, consistent revenue above long-term profits. As a result, even those who return to conventional breeding need to produce more heifers to alter total heifer availability. This circumstance exacerbates the current shortage, highlighting the intricate economic calculations dairy farmers must make in a volatile business.

Future Focus: Will Short-Term Gains Trump Long-Term Stability in Dairy Farming? 

The present breeding practices and prolonged heifer deficit are expected to have long-term consequences for the dairy business. These trends pose severe concerns regarding the sustainability and efficiency of dairy production. Will the quick profitability from crossbred dairy-beef calves balance the long-term advantages of ensuring enough heifer supplies? This problem has the potential to influence breeding methods significantly.

Due to present economic incentives, dairy farmers progressively leaning toward crossbreeding may see their choice becoming a standard practice. The guaranteed income from cattle calves offers a lifeline in an unstable industry. However, this change may accidentally diminish the total dairy cow herd, reducing milk production capacity and increasing reliance on shifting market circumstances for beef.

Suppose heifer prices remain low to encourage a return to conventional breeding. In that case, the business may progressively migrate toward farms specializing in beef-dairy hybrids. This trend may cause dairy farm operations to prioritize short-term profitability over long-term herd growth, thereby changing the farming environment.

Furthermore, dairy producers that oppose this tendency and continue with conventional breeding may find themselves in a unique situation. If heifer prices finally line with the risks and expenditures connected with their growth, these farmers might reap significant benefits. They may become major competitors in a market desperate for high-quality dairy cows, resulting in a competitive but more stable economic climate.

Finally, the endurance of these present breeding tendencies may signal substantial changes in dairy farming operations. Whether this results in a widespread move toward crossbred beef-dairy herds or a return to conventional breeding, today’s actions will influence the industry’s future. Dairy producers must balance immediate financial rewards and long-term herd viability when analyzing breeding options.

The Bottom Line

As we handle increasing heifer pricing and the transition to hybrid dairy-beef calves, it’s clear that dairy producers have a distinct set of issues. Despite having the highest on-farm margins in years, the heifer scarcity threatens long-term viability. While some ranchers continue to use conventional breeding techniques, most find the instant money from beef calves too appealing. This delicate balance between short-term profits and long-term stability will dictate dairy farming’s future. Will the heifer scarcity cause a significant shift in dairy production practices?

Key Takeaways:

  • Feed costs have decreased, and milk revenues remain stable, improving on-farm margins.
  • There is a significant shortage of heifers, driving prices to between $3,000 and $3,300 per head.
  • High beef prices incentivize dairy farmers to produce crossbred dairy-beef calves instead of purebred heifers.
  • From September 2023 to June 2024, 286,100 fewer milk cows were sent to beef packinghouses than the previous year.
  • Milk production has decreased in 16 of the 24 largest dairy states, affecting long-term herd management.

Summary:

Dairy farmers enjoy unprecedented on-farm margins thanks to reduced feed costs and stable milk revenues, but a significant heifer shortage hinders increased milk production. With heifer prices soaring—last week, the top 25 springers ranged from $3,000 to $3,300 per head at the monthly sale in Pipestone, Minnesota—and beef prices at record highs, many farmers are opting for crossbred dairy-beef calves, which offer a more immediate and reliable revenue stream. From September 2023 to June 2024, 286,100 fewer milk cows were sent to beef packinghouses, while milk yields are below year-ago levels in 16 of the 24 largest dairy states, complicating long-term herd management strategies.

Sire vs. Dam – Which has a Greater Impact on Your Herd’s Genetic Improvement?

Too many people say that dairy breeding is an art. If they manage their herds this way, they will be unable to compete in an industry that grows with science. Art places value on the ‘family’ and sees both parents contributing equally shared value to their offspring. In practicing the science of dairy cattle breeding parents are not equal when it comes to which one is the most important when deciding upon a herd’s genetic improvement plan (Read more: What’s the plan? And Flukes and Pukes – What Happens When You Don’t Have a Plan, and Pick The Right Bull – Your Future Depends on The Decisions You Make Today!).

3 Factors Determine Genetic Advancement

On a simplified basis, the rate of genetic advancement in a dairy herd is primarily a function of three factors: 1) the superiority of parents; 2) the accuracy of the parent’s genetic indexes and 3) the generation interval expressed as the time between the birth of the parent to the birth of the calf. Dairy cattle breeders have, in the past, placed a priority on intense selection, but today with genomic information generation interval is necessary.

Four Pathways for Improvement

In a population of dairy cattle there are four groups, commonly called transmission pathways that are considered when determining the overall population rate of improvement. These pathways are: 1) the Sires of Bulls (SB); 2) the Sires of Cows (SC); the Dams of Bulls (DB); and the Dams of Cows (DC). Breeders do not have equally accurate information on each pathway and definitely do not apply equal selection intensity for each pathway.

Which Breeding Scheme is the Best?

The following table outlines the importance of the different pathways for three improvement schemes when animals are ranked and selected using total merit indexes like TPI, NM$ and LPI.

Comparison of Genetic Improvement Schemes

Pathway Selection % Accuracy Generation Interval Relative Emphasis
1. Traditional Progeny Testing Program
Sires of Bulls (SB) 5 0.99 7 44%*
Sires of Cows (SC) 20 0.75 6 22%
Dams of Bulls (DB) 2 0.6 5 31%

* Pathway of most importance The Bullvine appreciates the assistance of Dr. Larry Schaeffer, University of Guelph, in providing information for the above  table. Further details can be found in Dr. Schaeffer’s 2006 paper “Strategy for applying genomic-wide selection in dairy cattle,” Volume 123 of Journal of Animal Breeding and Genetics.

Progeny Testing has Served Breeders Well

Breeders have been successful when they used the results of the traditional A.I. progeny testing programs. That is when only elite sires are used to produce bulls (SB) for progeny testing, each year newly proven sires are used to produce the heifer calves (SC), Dams of Bulls (DB) are elite indexing milking females and the bottom 10-15% of the cows in the herd are not used to produce replacement heifers. (Read more: Why you should get rid of the bottom 10% and  8 Ways DNA PROFILING Your Whole Herd Will Improve Your Breeding Program) most important pathway, by quite a distance, is the Sires of Bulls (SB) at 44%. Combined the sire pathways (SB & SC) account for 66% of the total genetic progress. That is opposite to what many breeders say ‘Sires are not as important as cow families. The cow family, in a herd, dominates.’

Genomics gives 185 – 200%

Over the past five years, breeders have become familiar with the program whereby the genomic indexes on young animals are used for animal selection.  Even though this program is much discussed, it has been implemented on less than 10% of the farms in North America. In Holsteins, less than 7% of calves registered are genomically tested. Breeders are obviously not confident with the lower accuracies and the much shorter generation intervals. So let’s dig deeper to see what the facts are when it comes to rates of genetic improvement. With the genomics program the relative importance between pathways shifts to where the Dams of Bulls (DB), at 40%, is the most important followed next by the Sires of Bulls (SB) at 34%. Again in this program, as in progeny testing, very limited selection pressure is applied to Dams of Cows (DC), pathway resulting in only 3% of the total progress. The relative ratios of improvement from sire and dam pathways is 57:43. The telltale important fact is that by using a genomic program the rate of annual genetic gain is 185% to 200% of what can be achieved by using the traditional progeny testing program. Another important difference between these two programs is that considerable money can be saved by only having to progeny test less than half as many young bulls with the genomic testing program.

Adding IVF gives 225 – 250%

Some breeders add IVF to their genomic selection program however due to costs and the challenge of mating carefully to avoid inbreeding it is not for everyone. The accuracies of this program match those of the genomic testing program, but the selection intensities are increased for the Sires of Cows (SC) pathway and greatly increased for the Dams of Cows (DC) pathway. For all pathways the generation intervals are short, something many breeders state as being a concern.  These farms use IVF on maiden heifers to produce all of the next generation of animals. Again the most important pathway is the Dams of Bulls (DB) at 36%.  However, the differences between emphasis on the pathways is narrowed. The ratio of emphasis sires to dams is 50:50. Farms employing this program can have annual rates of genetic gain of 225% to 250% compared to what is possible for herds using a progeny testing program. To fund this more expensive program breeders often sell surplus embryos or animals.

The Bullvine Bottom Line

Determining which parent pathway is the most important rests with which testing and selection program a breeder wants to follow. For breeders using the traditional progeny testing program by far the most important animals are the sires of the young bulls (SB) that enter A.I. progeny testing programs. For breeders wanting to advance their herds at a faster rate by using the less accurate genomic information and shorter generation intervals, the dams of the bulls (DB) is the most important pathway. No matter which program a breeder chooses it is important to have a plan and always use the best available animals.

Who Said You Can’t Breed For Higher Fertility?

If you were to describe the perfect program to achieve top female fertility in your herd, what would it be? Would your program include heifers calving at 22 months of age and every 11-13 months thereafter until lifetime production reaches 275,000 lbs (125,000 kgs) of milk? For decades breeders have heard that they can’t breed for fertility. It’s all management and nutrition. Well that story is changing. Let’s examine how genetics can play a role in improved fertility in a herd.

The Current Scenario

The CDCB (Council on Dairy Cattle Breeding) has summarized the following current reproduction information on the current US dairy cattle.

  • Holstein cows take 2.5 breedings per conception. Jerseys take 2.2.
  • Holstein cows average 80 days in milk before they are bred. Jerseys average 77 days.
  • Average calving interval for Holstein cows that calve back is 13.8 months. Jerseys average 13.0 months.
  • Average conception rate for Holstein cows is 32%. Jerseys average 41%.
  • Average age at first calving in Holsteins is 26 months. Jerseys average 23.5 months.

These stats for Holsteins and Jerseys are provided for breeders to benchmark their herds, not to start a breed war. In five years’ time even if a Holstein herd was able to achieve the current Jersey average it will not be good enough. The three biggest factors that stand out from these stats and that are in need of correction are: 1) days to first breeding; 2) number of breedings before conception; and 3) age at first calving.

As it turns out the reproductive performance of North American dairy cows and herds reached their lowest level in 2007 and since then there has been minor genetic improvement.

Breeders Must Address Fertility

An attitude shift is needed. We must move from tolerance of fertility to awareness that genetics plays a role. Not all breeders have accepted the need for change. The Bullvine analysed the sires with the most progeny registered with Holstein US over the past two weeks and found that nine, yes nine, of the top twenty had negative genetic ratings for Daughter Pregnancy Rate (DPR). In fact two sires had significant negative ratings of -2.5 and -3.5. In addition four of the twenty had only slightly positive ratings. In total 13 of the top 20 sires were not breed improvers for DPR. That is significant!

Some breeders have paid attention to the management side of fertility and have increased their pregnancy rate by aggressive heat detection, by using professional A.I. reproduction specialists (Read more: Artificial Insemination – Is Doing It Yourself Really Saving You Money?) by installing heat detection devices or by using hormone level monitors (Read more: Better Decision Making by Using Technology). However from the latest reports from milk recording, half the herds have a pregnancy percent of less than 15%. And only 10% of herds have a pregnancy rate of 21% or more. Clearly more attention needs to be paid to getting cows and heifers pregnant.

Genetic Tools to Aid with Fertility

Daughter Pregnancy Rate (USA) and Daughter Fertility (Canada) are the primary genetic evaluation ratings to use when selecting for improved female fertility. These indexes are created using data from insemination, milk recording and type classification.

However there are eleven other genetic ratings that have some influence on reproduction. Individually they may not be significant but collectively they can contribute to reproductive problems or solutions.

  • Calving Ease – difficult births delay cows coming into heat
  • Maternal Calving Ease – normal delivery benefits – cow, calf and staff
  • SCC – cows with mastitis are less likely to conceive
  • Feet – problem cows are not mobile and do not show heats
  • Rear Legs Rear View – cows that toes out are not as mobile
  • Milk Yield – high milk yield stresses cows. Breed for high fat and protein yields on lower volumes of milk.
  • Body Condition Score – high yielding cows that retain body condition are more fertile
  • Persistency – high lactation yielding cows that have flatter lactation curves put less strain on their bodies
  • Inbreeding – inbreeding negatively affects reproduction
  • Haplotypes – information is now coming available to show that certain haploids hinder reproduction
  • Semen Conception Rate – although not a genetic rating, low fertility semen should be avoided

Those are the tools available today. We can expect that, with the current research into genomics and reproduction, there will be new ratings to assist with breeding more reproductively sound animals in the future.

Selection Matters

The Bullvine recommends that after breeders short list the sires they intend to use that they eliminate sires that do not have a DPR over 1.0  or a DF over 103. Yes, female fertility is included in TPI, NM$ and LPI but the emphasis on fertility in these total merit indexes is not high enough to result in major genetic improvement for fertility. The following lists of bulls are examples of bulls that significantly improve total merit as well as female fertility.

Action Plan

It is important for both herd viability and sustainability that the following steps be followed.

  1. Do not use bulls that are genetically inferior for reproductive traits.
  2. Genomically test heifer calves. Eliminate reproductively inferior cows and heifers.
  3. Include genomic reproductive information when correctively mating females.
  4. Use heat detection devices, hormone level monitoring equipment or intensive staff heat detection.
  5. Use herd management software and herd protocols to assist with reproductive management.
  6. Ensure that animal housing and animal grouping result in healthy animals
  7. Feed cows and heifers according to their performance and reproductive needs
  8. Employ staff training and education program for reproduction.

The Bullvine Bottom Line

The genetic attention starting to be given to female reproduction on dairy farms is long overdue. The first step for breeders is to include reproduction in your herd genetic improvement plan (Read more: What’s the plan?). In as little as five years, by following a progressive proactive plan, breeders will significantly reduce their losses due to reproduction.
