Uncover the potential of Lactanet’s 2025 monthly genetic evaluations to elevate your Canadian dairy cows to premier status. Are your herds positioned to gain from this groundbreaking update? Learn more today.

A pillar of the dairy sector, genetic assessments are essential for herd management, breeding choices, and production. These tests concentrate on important factors like milk output, health, and fertility, thus empowering breeders and farmers to propel operational effectiveness and genetic advancement. Early 2025 will see Lactanet, Canada’s national dairy statistics and genetic improvement agency, moving to monthly official assessments for Canadian cows. This shift is significant for herds where milk samples are gathered unsupervised by the herd owner as it might improve more dairy cows to a top-rated level in genetic rankings. The change fits business trends toward automation, improved data-collecting techniques, and expands the genetic basis accessible to breeders.

Driving Genetic Progress: How Lactanet Canada Shapes the Future of Dairy Herds 

Crucially, lactate is the pillar of genetic development in Canada. The company provides complete dairy herd management solutions comprising milk records, genetic assessments, and advising services to boost dairy output and genetic enhancement.

Using solid data collecting and thorough analysis, Lactanet stimulates developments that support the national dairy industry’s sustainability and output. Three times a year, in April, August, and December, genetic assessments and bull proofs guarantee great precision and dependability. These tests provide essential benchmarks, including production characteristics, Lifetime Production Index (LPI), and Pro$, thus helping breeders choose the most genetically outstanding animals.

The way Lactanet combined genomic data emphasizes its dedication to genetic improvement. Lactanet accurately assesses the genetic potential of dairy cattle by using sophisticated genotyping, enabling breeders to make educated choices promoting long-term genetic improvement.

Lactanet guarantees the genetic quality of Canadian dairy cattle by matching modern genetic research with pragmatic on-farm data collecting, therefore advancing the sector.

Unveiling Hidden Potentials: Addressing the Genetic Evaluation Gaps in Owner-Sampled Herds

Even with improvements in genetic assessments, the existing method offers challenges—especially for owner-sampled herds. These cows are deprived of gaining places on top-ranking lists like the Lifetime Production Index or Pro$ depending on Parent Average (PA) values instead of exact genetic parameters from supervised testing. These cows typically stay underestimated in formal genetic evaluations without controlled testing data.

The triannual updates postpone the distribution of vital genetic information and further limit the acknowledgment of gene progress within owner-sampled herds. This lag narrows the breeding base, affecting individual breeders and limiting general genetic progress.

The introduction of automated milking systems with built-in sample features emphasizes the increasing discrepancy between contemporary herd management techniques and conventional genetic assessment approaches. In the present configuration, these systems generate large amounts of data that only partially support genetic assessments, developing a discrepancy between actual and evaluated genetic value.

To solve these problems and guarantee that every cow has fair access to top-ranking lists independent of milk testing control, the suggested change to monthly official assessments aims to This modification seeks to drive more successful breeding strategies by offering a more comprehensive and accurate picture of genetic quality in Canadian dairy herds.

Proposed Monthly Genetic Evaluations: A Game Changer for Owner-Sampled Dairy Herds 

The suggested adjustments will greatly help owner-sampled herds, including switching to a monthly genetic evaluation scheme. The first Tuesday of every month will be used to update genetic assessments for cows with fresh test results, including unsupervised samples. Official updates for proven sires will come three times a year; owner-sampled herds will frequently have their Parent Average (PA) values updated. This shift increases the genetic pool accessible to breeders by allowing these herds to have maybe cows included in top-ranking genetic lists.

Through monthly updates, Lactanet recognizes the growth in automated milking systems, which gather production data and conduct thorough sampling. This renders either supervised or unsupervised categorization less critical. The obtained data still shows excellent accuracy. Hence, genomics guarantees solid genetic assessments. This change toward regular and comprehensive updates seeks to optimize genetic advancement and enhance the genetic health of dairy cows throughout Canada.

Lactanet’s genetic assessment procedure revolves mainly around integrating genomics, the fundamental component of all genetic ranking systems used in Canada. The company uses a diverse strategy to guarantee the quality and completeness of the published genetic data. Newly collected data from bulls and females undergoing controlled testing is continuously included in the current dataset, updating the “unofficial” genetic assessments. Participating artificial insemination (AI) businesses and farmers using modern herd management systems like Compass and DairyComp may obtain these unofficial assessments. 

Implications for Breeders: Expanding the Genetic Horizon with Monthly Evaluations 

This change has significant ramifications for breeders. Monthly certified genetic evaluations will increase the genetic data accessible to breeders, enabling assessments based on actual performance rather than Parent Average values. This will increase the genetic pool from which sires and dams could be chosen. Frequent updates will ensure breeders receive the most recent genetic information, guiding their breeding choices. This precision will enable the identification of previously missed outstanding cows. More cows will land top-rated in genetic rankings.

Including information from automated milking systems and other cutting-edge technology will also help to guarantee ratings reflect actual performance. This will enable breeders to propel genetic advancement efficiently, improving dairy herd sustainability, health, and production throughout Canada.

Precision and Reliability: Lactanet’s Multifaceted Genetic Evaluation Process 

Using a thorough internal procedure, Lactanet guarantees accuracy and dependability in genetic assessments. This generates unofficial and formal genetic evaluations by combining data from known sires with supervised testing females. Shared via Compass and DairyComp, unofficial assessments provide vital information for temporary herd sire decisions.

Underlying all genetic rankings, Lactanet’s work is based on the integration of genomes. Genomic testing lowers the uncertainty related to conventional techniques by improving assessments’ accuracy and prediction ability.

Considered equally accurate are both controlled and unsupervised milk sample data. The emergence of automated technologies has improved sample integrity and milk production monitoring. Lactanet’s data analytics technologies tightly evaluate these inputs and match them with genetic data to provide high-precision assessments.

Combining conventional data collection, cutting-edge genomics, and strict validation techniques, Lactanet’s genetic assessment system is a diverse strategy that improves assessment accuracy. It increases the genetic basis accessible to breeders, promoting the ongoing development of Canadian dairy herds.

Technological Advancements: The Role of Automated Milking Systems in Modern Dairy Farming

Using automated milking systems signifies a significant change in dairy production, improving output and efficiency. These sophisticated technologies have reduced the need for supervised milk testing by including exact sampling and production monitoring features. Automated milking guarantees reliable data collecting necessary for genetic studies and fits with Lactanet’s shift to unsupervised testing, simplifying the procedure. This change enables significant genetic advancement and improves the quality of Canadian dairy herds by allowing cows to be included more broadly in genetic rankings.

Genomics and Unsupervised Testing: A New Era of Equitable Genetic Evaluations

Brian Van Doormaal highlighted the significance of these changes, noting, “For genetic evaluation, top lists usually involve genotyped females, so there’s little need to distinguish between supervised and unsupervised testing. The data accuracy is equivalent, and genomics ensures high genetic information accuracy.”

Mapping the Road Ahead: Key Milestones for Implementing Lactanet’s New Genetic Evaluation System 

As Lactanet gears up for its new monthly evaluation system, several pivotal milestones guide its implementation: 

  • Early 2024: Finalize criteria for cow eligibility through stakeholder consultations and in-depth analysis.
  • Mid to Late 2024: Conduct pilot runs and gather feedback to refine the evaluation process.
  • January 2025: Begin initial rollout, integrating the new system with existing triannual updates.
  • May 2025: Achieve full implementation, ensuring monthly updates for all owner-sampled herds.

This carefully structured timeline guarantees thorough preparation and testing, allowing Lactanet to maintain its commitment to accuracy and reliability.

The Bottom Line

Changing from Lactanet to monthly genetic tests might revolutionize the Canadian dairy sector. It levels the playing field for owner-sampled herds so they may reach high genetic rankings alongside monitored herds, hence increasing the genetic pool available for breeders. This action also fits the growing usage of automated milking systems, which combine cutting-edge dairy farming technology. Dairy cow rankings will become more dynamic and accurate, defining new national genetic advancement and herd development criteria.

Key Takeaways:

  • Monthly official evaluations will provide more timely and comprehensive genetic data for Canadian cows.
  • Owner-sampled herds, previously limited to Parent Average values, will now have their genetic evaluations updated monthly.
  • This change is expected to expand the genetic base available to breeders, allowing more cows to achieve top rankings.
  • Proven sires’ evaluations will continue to be updated three times annually, maintaining the reliability of genetic data.
  • The transition aligns with the rising trend of automated milking systems, which offer unsupervised sampling and monitoring capabilities.
  • Genomics remain fundamental to genetic rankings, ensuring accuracy across both supervised and unsupervised testing environments.
  • Lactanet is yet to finalize criteria for eligibility, with implementation set for early or mid-2025.

Summary: 

Lactanet Canada, Canada’s national dairy statistics and genetic improvement agency, is set to transition to monthly official assessments for Canadian cows in early 2025. This change is particularly significant for herds where milk samples are collected unsupervised by the herd owner, as it could improve more dairy cows to a top-rated level in genetic rankings. Lactanet provides complete dairy herd management solutions, including milk records, genetic assessments, and advisory services to boost dairy output and genetic enhancement. The proposed change aims to drive more successful breeding strategies by offering a more comprehensive and accurate picture of genetic quality in Canadian dairy herds.

CANADIAN BULL PROOFS – You’ve Got to Prove It to Use It!

No one likes paying upfront fees for anything.  After all, what’s the point of paying for something you haven’t received yet?  But there are some situations where paying upfront totally makes sense. Getting genetic information is one of those times.  You give up your money first and it translates into rewards later.

The Pieces are Put Together to Pull Together

Twenty years ago in Canada the dairy industry was faced with a challenge.  Government said it would fund research and development but not genetic evaluation services.  The goal was to shrink the cost and size of government.  The industry said these reports are valuable so we are going to have to get involved and that is what happened.

logo_cdn2_0[2]Canadian Dairy Network (CDN) was established in May 1995.  General Manager, Brian Van Doormaal, has been with CDN since its inception and summarizes the general details. “CDN is governed by a Board of Directors that primarily consists of breeders who are elected as representatives from four categories of member organizations, namely Breed Associations, DHI Agencies, A.I. organizations and Dairy Farmers of Canada.

The Canadian Dairy Network provides five major services:

  • Genetic Evaluation Services
  • Research and Development Projects
  • Industry Standards
  • Maintains the National Dairy Data Base
  • Operates the Data Exchange amongst the industry partners

It`s Fully Integrated and Always Moving

In the simplest terms, all the relevant information is shared by those who contribute.  Examples are:  Breed pedigrees go to CDN; CDN shares them with everyone who is a partner; DHI records go to CDN and are shared with partners.  These and more types of information are available to all users at all times via the Internet.  Everything can be found at the CDN website AT NO CHARGE for lookups.

The Dollar Division

Van Doormaal updates the funding process behind CDN. “All activities of CDN are financed by the industry organizations that are its members and for this reason the CDN Board of Directors has established an equitable service fee structure.” He further breaks out the pay structure. “80% is paid by AI and 20% by breed associations and milk recording provide their information at no charge to CDN.”

FEES: Fearsome Hurdle or Forward Thinking?

When there is a 79% cost increase (effective April 2013), there are going to be questions. Namely, “How did CDN determine the cost of $7500 to prove a bull in Canada?”  Previously the fee was $4200. The same fee has been set on a per bull basis for privately owned genotyped bulls, starting April 2013.  CDN does not have any other fees so this is an all-inclusive rate that gives the bull owners access to various services associated with genetic and genomic evaluations.”

Van Doormaal further clarifies. “With the arrival of genomic evaluations in 2009, operational costs have risen due to increased staffing needs and computer power while the number of young bulls with semen released in Canada each year has almost halved.”  Obviously, the plan is three-fold:  provide more research; more development and, at the same time, cover costs into the future.

Everybody Pays!

Van Doormaal stresses that, “In one way or another, all people and organizations will be paying fees to receive genetic and genomic evaluation services from CDN for bulls. While the mechanism for paying differs for breeders compared to A.I. organizations that are members of CDN, the level of payment is equivalent.  On the female side, no fees are applied on an animal basis since the breed associations contribute to funding CDN activities on behalf of their members.”

What’s Up in Other Countries?

Van Doormaal knows the international scene and explains, “While there are other countries like Canada for which the genetic evaluation services are financed completely by industry stakeholders, as opposed to government, each country inevitably ends up with its own funding formula and mechanism.” He speaks of the American situation.  “In the US, the mechanism proposed for financing its genetic and genomic evaluation services includes some level of fee applied to every male and female for which a genomic evaluation is to be calculated.”

Proving Your Own Bull

When asked about advice for breeders looking to prove their own sires, Van Doormaal urges. “Genotyping young bull calves shortly after birth makes as much sense for breeders as the genotyping of their newborn heifers.  Once the genomic evaluations are available to the breeder, better decisions can be made about the bull’s future.  Owners (AI or breeders) of bulls with outstanding results can then pay the CDN fee to make results official and have the young bull ranked among others available in Canada.”

LPI Formula Changing

Van Doormaal reports “The LPI for Holsteins in Canada currently has a range in values of approximately -3000 to +3000, which is three times bigger than the TPI in the United States and over 50 times bigger than national indexes used in most other countries.

The CDN Board of Directors decided, after consulting all stakeholders, that the LPI scale should be halved.  To achieve this objective while maintaining the current level of LPI values for the highest progeny proven bulls, it was decided to add a “constant” value to the LPI formula in a manner similar to what the United States has done for years with its TPI formula. Conversion from current LPI values to the proposed new scale is simply done by dividing the current LPI in half and then adding the constant of 1700.”

LPI Formula Give and Take

Another adjustment Van Doormaal expects to happen to the LPI formula relates to the specific traits included and the relative emphasis placed on each.  Analysis of various options and discussion will proceed through 2013 with a likely implementation of an updated formula in April 2014. Based on feedback received from a cross-section of breeders, there seems to be a general interest to increase the overall emphasis on longevity, fertility and disease resistance in the formula. Of course, once the emphasis is increased on some traits, there also has to be other traits losing emphasis.

Future CDN Genetic Evaluation Evolution

In December 2012, CDN introduced Body Condition Score as a newly evaluated trait for all breeds, which can be used as an indicator for fertility, disease resistance and longevity.  The release in December 2013 will include the first official genetic evaluations for Mastitis Resistance in all breeds which should be followed by Resistance to Metabolic Disorders in 2014.  Other traits on the planning horizon within the next five years include desirable fatty acids and other components of milk, hoof health and feed efficiency.

Changing Gears for Genomics

Van Doormaal provides updates resulting from the introduction of Genomics. “Prior to 2009, CDN had six different genetic evaluation systems, which were run monthly to evaluate over 60 traits including production, type, longevity, female fertility, calving performance and milking speed/temperament. With the arrival of genomics, a new system was developed and implemented, which estimates Direct Genomic Values (DGVs) for all traits and combines them with traditional evaluations to produce the published genomic evaluations.  This new system is also run monthly and also required the establishment of a national database to process and store all genotypes, which now totals over 310,000 across all breeds. Operationally, these new services that are highly valued by the industry organizations and breeders, have required additional geneticists and new web site development as well as investments in advanced computer equipment and processing power.”

CDN: Providing Global Genetics and Genomics

Looking to the future, Van Doormaal gives an overview. “The era of genomics is still in its embryonic stages.  It is difficult to predict the extent to which it will continue to impact the dairy cattle industry over the next 10 or 20 years.  One thing for certain is that the world of genetics will continue to shrink at an increasing rate since it is so easy to collect DNA from any animal in the world and assess its genomic evaluation on numerous country scales.”

CDN:  Fine-Tuning

CDN will dedicate much time and effort in the coming years to fine-tuning existing traditional genetic evaluation systems and methods for estimating genomic evaluations. Van Doormaal is realistic about the possibilities. “The shift towards a higher market share held by genomic young sires compared to progeny proven sires will likely experience some pendulum swings, eventually reaching stabilized proportions as breeders and industry gain experience in the coming year.”

After 25 years working and educating in the Canadian proving system, Van Doormaal is proud of the achievements. “We are fortunate in Canada to have many geneticists and research scientists who realize that the ‘practice’ of genetic selection and mating is not the same as the ‘science’.  Both sides need to continue to respect and listen to the knowledge and experience of the other. The most progress is made by incorporating the ‘science’ of genetic improvement into a solid, practical breeding program.”

BULLVINE BOTTOM LINE:

Recognizing the potential of responding to changes in the industry, in technology and from science, CDN is focused on the future on behalf of breeders.
