For years there has been great debate between dairy breeders and producers about what type of cow is the most profitable. There are sound arguments on both sides of this issue. However, developments arising from new indexes and analysis highlight that it’s not always the prettiest cow that milks the most over her lifetime. To paraphrase the popular song, these cows prove that “She ain’t pretty, she just milks that way!”
Are show cows great lifetime milk producers?
We are all guilty of it. We see the cows that win at World Dairy Expo, The Royal, Swiss Expo, and IDW and are amazed at their extreme size, capacity, and dairy strength. We look at them as the epitome of what the ideal cow looks like. And it’s fair to say that the production level of these animals has greatly improved over the past 30 years. However ask any commercial producer in a large free stall environment and they would tell you that these winners would not be the ideal cow for their operation or to maximize their revenues. The very characteristics that make them great in the showring (their massive size especially) would limit their efficiency for these producers. (Side note: With dropping sale prices show cows and especially high index cows are not bringing the same resale value as they once did – Read more: An Insider’s Guide to What Sells at the Big Dairy Cattle Auctions 2013).
Now here at the Bullvine we like to deal in facts not hearsay. So we took the top 10 animals from the Mature Cow Class at the 2013 Royal and here is what we found. They average an amazing 95 points with a couple even going Excellent multiple times. The scarier part is that they only average 2.5 complete lactations each, out of a possible 4, and just over 50,000 kgs of lifetime production. With the winner of the class, having out of three lactations started only completed 2 by 7 years of age and produced under 48,000 lifetime. Now some would say, “Yes that is because all the big producers are in the Lifetime Production Class.” So we decided to take a look at that class as well. Surprisingly this class averaged a slightly lower 94 points, and just over 3.5 completed lactations each, out of a possible 5, and 61,647 kgs. of lifetime production. Not exactly extreme for a class that is supposed to be the epitome of the breed. However there was one strong exception in the class, STARBRITE LYSTER LYNDSAY, who at EX-96-3E, with 5 completed lactations and 84,282 kgs (185,808 lbs.) of lifetime production, certainly is a testament to longevity. That is probably why she is a perennial contender and a huge fan favorite.
Are high scoring 2 year olds good lifetime producers?
Then of course there is type classification and the true type model. Believing in full disclosure, we here at the Bullvine are big fans of the type classification system (Probably because my father ran the Canadian Type Classification and Breed Improvement Program, for 18 years in the 70’s and 80’s) and have written many articles about it (Read more: TOM BYERS: “THAT’S CLASSIFIED!” and Is Type Classification Still Important?). But more and more we are beginning to question some of the long standing beliefs that we have had relating to type classification and longevity.
There is no doubt that the goal of the type classification system is to produce a long lasting profitable cow. What is becoming more apparent is that what we believed it took to achieve that may not have been functionally correct.
Now it would not be fair to make a blanket statement like that, nor would it be Bullvine style, if we did not back that up with cold hard numbers and examples. I cannot think of a better example than, GILLETTE E SMURF, the world record holder for lifetime production at 242,303 kgs (534,181 lbs) in 11 lactations. (Read more: World Records Are Not Only Set at the Olympics). As a two-year-old Smurf scored GP-83, with Dairy Strength (82) and Feet & Legs (80). These two the traits kept her from going VG. What makes this surprising is those are the two exact traits that many believe are the greatest indicators of longevity. Yet the greatest producing cow in the world was deemed to be lacking in those areas. In fact it was not until 10th lactation and over 216,893 kgs of lifetime production that the classifier deemed that Smurf had enough strength (97) and sound enough legs (86) to make her an excellent cow.
Now as we always say it is easy to find case by case examples. But do the numbers hold up across multiple animals and larger groups? We decided to look at all the VG-89-2yr olds from January 1st 2007 to December 31st 2010. In that time there were 20 VG-89 1st lactation cows that have remained in Canada. 60% of them have gone on to classify Excellent, with the group now averaging 91 points. The alarming part is that, as a group, they have completed on average 2 lactations each out of a possible 4, with lifetime production averaging 42,262 kgs. In fact only 30% of them have even completed a 3rd lactation. That percentage is even less than that of the mature cow class at this year’s Royal. Achieving VG89 first lactation certainly is not a good predictor of lifetime production. In analyzing the US numbers we found similar results.
So what is a good predictor of lifetime production?
We all have in our mind what the ideal mature cow looks like. For many pedigree breeders it’s a cow that looks like this. (Read more: The Perfect Holstein Cow)
In taking that one step further, we also did a composite of what the perfect classification 2 year old would look like.
But in reality, as we have mentioned earlier in this article, these cows are not the epitome of lifetime production animals. In fact they are not even bull mothers. Currently the typical ideal high genomic 2 year old/bull mother looks like this.
But in analyzing the numbers, especially productive life and herd life, the true ideal 2 year old should look something like this.
First, let’s make one thing clear. Unlike indexes like TPITM and LPI that try to predict lifetime production based on hypothesis and our understanding of what we think it takes to make a long lived productive cow, productive life (USA), and herd life (CAN) measure actual longevity. They measure how many months the cow actually is a productive member of the herd compared to herd mates.
This means that our long-accepted theories that a cow needed to have a wide muzzle, deep chest, and deep sweeping open rib in order to be a high lifetime producer are actually incorrect. As we pointed out in Breeding for Longevity: Don’t believe the hype – It’s more than just high type, the top 25 productive life proven sires in the Dec’13 genetic evaluations actually average only 0.52 for Dairy Character and 0.47 for Body Composite.
This actually makes sense. When you look at the top two reasons given for non-dairy purposes sales, infertility and mastitis, they account for almost double (26.9%) the number of animals culled for production or conformation reasons (18.5%). Basically we learn that, when it comes to predicting longevity, there are many contributing beyond conformation.
That is why it’s not surprising when we interviewed Don Bennink of North Florida Holsteins, a very commercial production oriented breeding program, type and conformation where not even on his list of selection requirements. (Read more: NORTH FLORIDA HOLSTEINS. Aggressive, Progressive and Profitable!!). In fact if you really want to break down the numbers into the nuts and bolts simplicity, you would only look at two things. In the US that would be pounds of milk production (with some allowance for %F) and productive life. In Canada that would be kilograms of milk production and herd life.
So here at the Bullvine we like to complete the steps for you. We looked at all the proven sires who are over 1250 lbs of milk and 5 for productive life. The results were very telling. There were 40 sires that made this list, with the top 6 reading like a who’s who of top selling sires, Bookem, Freddie, Robust, AltaMeteor, Shamrock, and Observer. Also it is interesting to note that these sires average 2.77 SCS, 6 CE, 1.33 PTAT, 1.23 UDC, 1.23 FL&C and 2026 TPI.

The Bullvine Bottom Line
Any way you look at it, it’s hard to argue with the cold hard facts. For years the show ring and type classification have tried to do the best job possible in predicting what it take to produce a long lived productive cow. But just like the evolution of the computer, healthcare and science, as more information becomes available, we find that some of our previous beliefs are no longer accurate. In no way am I saying that there is not value in programs like type classification, it is just time for those programs to evolve and do a more accurate job of predicting longevity. (Read more: What is the role of dairy cattle breed associations?) As the numbers show, today’s longed lived productive cow, may not look that pretty, but she sure milks that way.
Want to learn more about his? Andrew Hunt will be presenting at Canadian Dairy Expo on February 5th.
I still don’t like the fact that we are ignoring great bulls out there all because of the hype of productive life. There are still several problems with that formula, in particular the idea that frail cows will last longer (which I think is BS). In the meantime, Until that formula is improved, I won’t really pay attention to it.
Eduardo,
Productive Life is not a formula. It is the difference the length a sires daughters last in a heard (in months) compared to the average sire. It’s not a hypothesis index, is actual production info.
The Bullvine.
But then something isn’t being measured correctly somewhere.
Eduardo, the Colombian case as well as some other Andean countries is very specific because of the elevation factor. In this particular case at 2600 meters above sea level dairy strength is by far more important than under Canadian and USA conditions at 0-500 mts Also, the avg strength of Colombian cattle is lower than here, that’s why it is important to consider that trait as you mentioned and I share your concern. Now, the problem and the big failure is that for many years Colombian breeders as well as many other countries, only focused on type, bus as Andrew mentioned numbers are facts and He is totally correct in his approach too. From my stand point you breed the cow that you need and combining both perspectives yes we should look for a strong, nice functional cow, and yes we need to select cows to get pregnant and live longer, are we aware that the PL range today in USA bulls is 13 months? 13 months extra avg per daughter??? between the best and worst bull? that is an incredible difference and no doubt that will affect profitability no matter how and where you produce milk. So, Just to give you an example of this philosophy, I wanted to use planet in my herd because of many reasons, but I didn’t buy a straw because he was not good in dairy strength, then I waited for Shamrock, the improved version of planet for our specific breeding program and a bull that for me provided the best of both worlds.
Hi Eduardo ! Greetings from Brazil ! This is an issue that in my opinion Dairy Producers should think more about it , facing high costs for milk production and raising a good replacement heifer. I’d like just to point some details that maybe could contribute a little to this Productive Life issue.
When you mentioned it as formula … it made me think on the PL index in the US Dairy Bull Proof. That weights the main traits that researches have shown what could make a cow stays longer in a herd or leave earlier and also the economic important traits that play an important role in a long life profitable dairy cow … So far , she must make Money too ! Source : PRODUCTIVE LIFE – USDA-AIPL , 12-2012:
DPR – DAUGHTER PREGANCY RATE = .60
SCC – SOMATIC CELL COUNT = -.45
CALVING ABILITY TRAITS(CALVING EASY -SCE,DCE, STILLBIRTH SSB, DSB) = .40
BODY SIZE COMPOSITE = -,26
UDDER COMPOSITE = ,15
PTA PROTEIN = ,10
PTA MILK , PTA FAT = ,08
FEET & LEGS COMPOSITE = ,08
That would give us an idea of how are bulls being selected to promote Productive Life improvement , so that would represent the GENETIC part.
How many months a cow stay longer in production , lifetime, in a herd compared to her herdmates would represent the PHENOTYPE , or the Genetic Expression + Enviroment.
So, when I think about that what comes to my mind is not a Top Show Cow but a functional cow , and they do look different until now. In my opinion depending on your breeding goals you may select for a high type show cow or a very profitable and functional dairy cow. But in fact , at the end , what really will lead the situation is the Market . What it pays for ? What makes more Money for a major number of Dairy breeders.
I love being on great Dairy Shows , they are very important , that´s where all the old and new dairy people can get together, make business, talk about cows , exchange experience, find motivation to keep up their day to day good work being around dairy cows !
I think many progress can be made in the future selecting for longevity so as it have been done on Type, as more and more dairy breeders globally have been feeling right in their pockets how important key they are in a profitable dairy operation nowadays.
Hope this can contribute !
Regards !
