Preferential Treatment – The Bull Proof Killer

Accuracy of bull proofs has been one of the biggest challenges for dairy cattle improvement for many years.  It has been well known that top index cows have always received some level of “preferential treatment” and as a result their indexes have been inflated.  Usually this didn’t affect their sire’s proof since they were usually already proven sires and when weighted with many other daughters this had little to no effect on the sires proofs.  Enter genomics and large portions of young sire daughters receiving preferential treatment and this could have huge effects on the proofs of these genomic index bulls.  There is no question that the current systems around the world cannot account for this preferential treatment and as a result many genomic sires’ first proofs will be inflated.

In the past when young sires were sampled they were used across many different herd environments and regions.  I remember when regionally proven sire (California, etc) or breeder proven sires were released. Many breeders where hesitant to use them because they were not confident that these sires proofs would hold up.  Young sire programs in the past offered semen at low cost or pretty much free (when you factor in incentives) to many different breeders in order to ensure that the sire got enough daughters and that they would be able to achieve a reliable proof.

Does random sampling still exist?

Young sires are no longer randomly sampled.  In today’s genomic age, a lot of the systems and controls are gone.  Yes, many of the sires are still offered to all breeders, but these high-ranking young sires are sold at a much higher price, and marketed much heavier.  In addition often the first release semen is only used on contract matings on extremely high index, carefully selected mates.  This results in anything but random sampling and in reality is almost the perfect method for receiving an inflated proof.  It isn’t just because of the actual mates they are being used on but also because of the care the resulting calves will receive.

Why do daughters receive preferential treatment?

Think about it, if you have paid upward of $750 for a dose of semen (Read more – $750 Dollar Semen! Are you crazy?) to be used on your most valuable animals, wouldn’t you make sure you protected your investment by giving them the best care possible?  It is well known that top index cattle around the world have received over inflated indexes as a result of preferential treatment.  The problem is ‘how do we account for the biases?

Does the current system account for preferential treatment?

Genetic evaluation systems assume that all animals in the herd are treated equally.  Yet while there is nothing wrong with a breeder wanting to ensure their return on their investment in these top genetic animals, it certainly causes many problems when accounting for it in the genetic evaluations of these animals. (Read more – The Hot House Effect on Sire Sampling).

Most “animal-model” genetic evaluations in the world account for the genetic merit of a sire’s mates.  However, when the US first added females to their genomic reference set they actually got lower reliabilities as a result of inaccuracies in female’s proofs due to preferential treatment.  That is why some countries actually leave female genomic data out of their reference sets, as a large portion of the females are these high index animals that, in many cases, have received preferential treatment.  In the US they actually implemented a scaling-effect adjustment to bring those top females down.  The US has also implemented a new single-step model that includes genomic and traditional data together designed to account for this in bull proofs.  Other countries are also looking for potential solutions.  This includes potentially withholding early data from evaluations as well as other options.  The challenge is that no one has found a real solution to the actual problem, and steps so far just mask the issue with scale downs and other band-aids.

How to identify preferential treatment?

I recently attended a GEB session put on by CDN (Canadian Dairy Network) where they gave a presentation on accounting for herd bias.  Brian Van Doormaal presented a few different ways he theorized would identify bulls’ daughters who might have received this preferential treatment.  One indicator he presented of possible preferential treatment was if a high percentage of a bull’s early offering were the result of ET.  Another indicator he looked at was the percentage of daughters that have been genotyped.  However, neither delivered conclusive results.  Another suggestion that was presented was increasing the number of daughters a sire needs  in order to receive an official proof.  The challenge with that is that A.I. companies and most high profile breeders are wanting sires to get a proof as quickly as possible and increasing the requirements will cause delay.  In addition, analysis of semen price so far does not show it to be a great predictor either.  Currently there are simply no answers.

In Brian’s presentation he equated this problem to the challenges we have seen with second-country proofs.  In Canada bulls like Shottle, Planet and more recently Man-O-Man (Read more – Man-O-Man will he turn platinum? and Is Man-O-Man really going to be a sire of sons?) that come through with initial Canadian proofs over 3500 LPI, which everyone knows to be unrealistic, in time saw their proofs drop 300+ points with the addition of more daughters.  Van Doormaal also comments that you could expect bulls like Snowman, and genomic sires to do the same.

The Bullvine Bottom Line

Currently there are no definitive answers only growing concerns.  This preferential treatment problem is going to get greater attention, as more high profile genomic sires,  priced high and highly marketed will start to receive proofs in 2013. The industry must be proactive about this issue. If not we are going to see breeder confidence in proofs decrease, instead of increase, because of genomics. That would be a killer!

Bullvine Performance Index (BPI) – Top Sires December 2012

While there is no doubt that national composite index’s (TPITM, LPI, PLI etc.) are great marketing tools, recently there has been  discussion about their merits as actual genetic advancement tools.  With each index providing “home field” advantage to domestic animals and many out of date with where the industry is headed, we here at the Bullvine have developed the Bullvine Performance Index (BPI).

In the BPI we use direct genomic values instead of parent averages and we also incorporate reliabilities, in order to greater account for animals whose indexes stand the best chance of being stable over time.  As far as what traits we looked at, we have used an equally balanced weighting between production, longevity and health and fertility, as we see that emphasis represents where the market is heading.  We also include a small component (MPS) that factors in dam, 2nd dam and 3rd dam actual performance irrelevant of country of origin, as per our discussion with many breeders who feel that this should have some weight.  Instead of trying to be reactionary to the marketplace like most composite indexes, we are trying to be leading and ahead of the market.  We also are publishing BPI as a percentage so that it is clear just how far apart each animal is from each other.  Since this is a ranking index we felt it was more important to show the range between animals than to give a number that technically means nothing.

Key Findings

  • One of the neat things we found in developing this index is that it is able to give a realistic comparison between sires from all countries.
  • Even more importantly it also gives a good comparison of genomic test sires versus proven sires.  Four of the top ten sires are proven sires, as compared to most national indexes that, when combining the genomic sires and the proven sires would find that at least nine if not all ten would be genomic test sires.
  • Outside of MR LOOKOUT P ENFORCER most of the sires are very close and really do warrant that you make sure you use the corrective mating for your specific animal as opposed to just using the top 5 or 10 bulls.
  • Another finding was the ability for second crop sires to also compare favorably with genomic test sires.  Besides Man-O-Man (LONG-LANGS OMAN OMAN-ET) other second crop sires who come up high are UFM-DUBS ALTAESQUIRE-ET (BPI of 68%) and BRAEDALE GOLDWYN (BPI of 66%).  This demonstrates that these high reliability sires very much still have value in many mating programs.


  • There is no question that MR LOOKOUT P ENFORCER offers an extremely balanced package.  His strong production numbers combined with his extreme type and longevity with good health and fertility traits will have him be a sire of sons worldwide.  He may be hard to get your hands on as he is just one year old and he may only be released for contract matings.  This Marbri Facebook son has the highest DGVs in the breed.  Look for him to sire extreme component yields from strong dairy cattle with great feet and legs.  One area to be cautious on using him is his body depth.  Both his sire stack and his DGVs would say this area needs protecting.
  • There is no question that this last proof round Man-O-Man (LONG-LANGS OMAN OMAN) stole the show.  His outstanding second crop daughter numbers have many top index breeders going back and using him again.  His extreme production numbers have him and his daughters in high demand.  With many sons like UNO also coming on the scene and offering a more balanced offering, it’s important to make sure you use Man-O-Man or maybe GENERVATIONS LIQUID GOLD when looking for the splash of production for a high type, high health and fertility mating. However hold off, if you are looking to improve those areas.  Use a more balanced sire like MR LOOKOUT P ENFORCER-ET or maybe SOUTHERN-HILLS BAYARD-ET.
  • Coming up strong, as he keeps adding daughter numbers, is COYNE-FARMS DORCY.  Look for Dorcy to sire balanced dairy cattle that have great udders and very good feet & legs, though he will need to be protected for dairy strength, fat percent and, specifically, for his body depth and chest width.
  • Also catching our eye are a couple of Freddie sons – SOUTHERN-HILLS BAYARD and HAMMER-CREEK FRED KRUNCH.  Both these sires offer a greater type and longevity option over their sire BADGER-BLUFF FANNY FREDDIE who suffers on our BPI index as his second and third dam’s classification and performance scores are low.
  • The top non- North American sire on our list is GOLDDAY.  Goldday is a Goldwyn son from A-L-H DESTINY VG-87-3YR-USA DOM GMD.  Destiny is of course the popular bull mother from Markwell Durham Daisy (Read more – Markwell Durham Daisy – 2012 Golden Dam Finalist), proven in Germany.  Goldday is also the full brother to former #1 German sire Danillo.  Look for Goldday to sire unbelievable udders and legs as well as long herd life.  One area where you will want to protect Goldday is rump angle.  Be cautious in using him on cattle that need production improvement.

The Bottom Line

It is difficult to keep track of all the top animals and compare them accurately. Trying to compare genomic sires with proven sires with each country having their own index with apparent bias makes it doubly hard.  Having said that, comparisons are instructive for informed decision-making.  That is why we developed the BPI formula.  Contrary to popular belief that you need to be using 100% genomic sires to accelerate your genetic advancement, our analysis shows absolutely that there are  proven sires that should be used in order to minimize your risk and still achieve the greatest results.

Is the Genomic System Really Working?

With Genomic sampled sires starting to get proofs, many breeders are finding themselves asking, “Is genomics really working?” Since it takes about 36 months for a sire to be sampled this is the first round we can start to evaluate the genomic system since its release in August 2009. To answer that question we decided to take a close look at how the system is working and if there are any early trends indicating if it is or not.

New Release Sire Performance over the past 2 Years

Probably this first place to look is how the young sire sampling programs are working proof round over proof round. (Due to the access of information, we are using the CDN system for this analysis).


# of New Release

Average LPI*

# >2000 LPI





























*not base adjusted

Let`s start with the good news. The breed has been advancing when factoring in the base change. Now the not so good news, when compared to previous rounds at delivering top sires the numbers are not so pretty. As you can see by the table above, the last two proof rounds have not been so favorable for genetic advancement). We see the lowest average LPI from the sire sampling programs, with also the lowest number of elite sires being proven. This caused us great concern about the merits of the genomic system at delivering top sires and so we decided to look even deeper.

What’s going wrong? Or Right?

To get a better understanding of just why this last round was the 2nd lowest performing round in the past years (only behind Apr 2012) we decided to look at the group of young sires receiving proofs this round and discover whether it`s the system or how we`re using it.

In order to determine this we figured it would be best to compare the old system, top 10 parent average LPI (PA LPI) sires to the Top 10 Genomic sires (GPA LPI) and see how they stacked up. For the record her are the two groups.


The results are as follows:





Top 10 GPA LPI




As you can see from the table above the GPA LPI sires outperformed the PA LPI sires by 27.1% indicating that the GPA system is a better indicator of estimated performance than the old PA system. In actuality, the top 10 GPA LPI sires actually increased their numbers by 3%, contrary to the expected drop. Even all 119 sires only averaged a drop of 89 points (9%) contrary to some other stats showing sires drop upwards of 20% from GPA LPI to the official LPI proof.

It’s also important to note that with an average official LPI proof of 2033 (445 points for base change) would have this group rank #5 behind the August 2009 proof round behind (Shottle, Justice, Goldwyn and Ashlar) with BRAWLER’s base adjusted proof (3083=2638+445) falling behind Shottle’s August 2009 proof of 3873.

So if it’s Not the System, What Is the Problem?

As the analysis of the PA LPI system vs. the GPA LPI system above indicates the issue is not the system. So then the question becomes, is it how we are using the system? Or are we just going through a lull? That question is tricky to answer. If we look at a longer period trend using currently available data from CDN we see that the two proof rounds before this period where even lower performing than the last two proof rounds.

Round # of New Release Average LPI # >2000 LPI









It may also be that as an industry we are still very much learning how to use the Genomics system and sire selection practices have to adjust for these changes. When we look at the PA LPI list vs. the GPA LPI list we see two herds whose sires on average drop between 400 and 600 LPI points. Can we say hot house effect? (to read more Has Genomics Knocked Out Hot House Herds?)

The Bullvine Bottom Line

It is still early to weigh the success or failure of Genomics. The early indicators show that it is a 27.1% improvement over the old PA system. There is still much room for refinement and education on both the breeder side and the sire sampling side!

Eight Proven Holstein Sires to Watch For or to Watch Out For

Far too often many proven sires get missed. This can be for two reasons. Either their initial proof is lower than expected or everyone is so caught up in using the latest genomic release sires, that they miss some great ones.  And then there are those new release sires that certainly seem to be amazing and then   plummet to earth like a meteor.  In order to help breeders understand which sires are which, we took a closer look at some of today’s top proven sires.  Here is what we found.

(Please note: Due to the need to get DGV values all numbers are based on the Canadian System)

Sires to Watch for

    With a dam that has MACE proof of over +4000 MLPI, it can be pretty scary for many breeders to use a MACE sire that is so high.  Concerns that his proof is all parent average and genomics are not unusual.  However, when it comes to MASACLESE his daughters are actually backing up what his family and genomics would indicate.  His young sire proof estimates (65% Genomics and 35% Parent Average) would be +3019 MLPI and his MACE proof has him at+ 2972, telling you that, while his daughters are slightly lower, they are not far off.
    While no means a new release sire ALTAESQUIRE’s 2nd crop daughters seem to be outperforming his first crop proof.  Watch for ALTAESQUIRE to sire more production, components as well as better mammary systems than his current proof would indicate. Currently ALTAESQUIRE’s proof is held back significantly by his low parent average MLPI of +1763, that is 1171 points lower than his current official MLPI proof of +2934.  With the addition of more daughters watch for his official CDN proof to have him among the top 2-3 LPI spots.
    With so many sires from De-Su at the top of the genomics list, and breeders expecting that the top genomic sires will drop with the addition of daughter information, ALTAGOALMAN has actually outperformed his genomics and parent average.  With a PA MLPI of +1960 and DGV MLPI of +2710, ALTAGOALMAN’s official proof MLPI is +2887, indicating that his daughters are significantly outperforming expectations for both type and production traits.
    Unlike some sires that are significantly helped by their Parent Average’s SANTANA is actually significantly held back by his parent averages.  With an official proof MLPI proof of +2854 that outperforms his strong DGV MLPI of +2778 and his not so strong PA MLPI of +1678, SANATANA’s daughters are performing significantly better than expected, especially for production and components.
    Here is one Goldwyn sire that I think many breeders might have missed. His lower DGV’s (DGV MLPI of +2024) and parent average of +1420 MLPI, do not spell breed topper.  With an official MLPI proof of +2392, ARTES’s daughters are significantly outperforming expectations.  While already among the breed leaders for type, watch for ARTES to be a significant type improver across all the major type traits, as well as giving significantly more production than expected.

Sires to Watch Out For

    As we highlighted in our recent article The Effect Genomics Has On The August New Release Sires, DORCY’s current daughters are not performing as high as his Genomics (DGV MLPI of+ 2726) would indicate.  Even when you factor in his lower parent average (PA MLPI of +2016) his expected young sire proof would have been +2477 MLPI higher than his current official proof of +2305 MLPI, indicating that his daughters are currently performing below his parent average.
    Living up to expectations can be very challenging,   especially for sires that come from extreme families.  That is the challenge EXPLODE finds himself in.  With high genomics (DGV MLPI of +2333) and parent average (PA MLPI of +2127), EXPLODE falls short of what his young sire evaluation would be (YS MLPI +2261), with an official MLPI proof of 2183.  Specific areas to watch out for are his feet and legs and rumps, based on current daughter performance.
    When his first proof came out END-STORY was not genomically tested.  Being a late Oman son and internationally proven, many breeders were hesitant to use END-STORY, fearing that his numbers would not hold up.  His daughters are significantly outperforming his DGV’s (DGV MLPI of +2419) and PA MLPI of +1504, with an official proof of +2502 MLPI.  The hesitation factor is that with 57 daughters in 39 herds, there is plenty of potential for END-STORY’s proof to go in either direction.  If the daughters live up to the numbers, he may have many breeders thinking twice and those that took the risk looking pretty smart.

The Bullvine Bottom Line

While we are not saying don’t use bulls like DORCY or EXPLODE, what we are saying is to use them with some level of caution, as current daughter performance has them below their DVG’s and parent averages.  This does not absolutely mean they will drop with the addition of more daughters, but, if the additional daughters maintain current daughter performance, then a drop is in their future.

Old School Dairy Breeders – Stop Pissing On Genomics

Old school breeder pissing on genomics!!!!

Recently as part of our weekend humor series we published the picture seen at the right.  In publishing the image we knew we would get a reaction, but we were surprised at the way breeders interpreted it.  While we intended to show how old school breeders are dissing on genomics, but instead it seemed to become a rallying cry for old school dairy breeders.

The conversation that has stemmed from it has been very interesting.   As you can see, there are still many breeders who don’t totally understand the merits of using top genomic young sires.  In an effort to help educate, or maybe just bang my head against the wall, we have prepared the following details. .

Proven vs. Young Sire – Who wins in the long run?

Let’s take a comparison of the top 10 Genomics Young Sires vs. the Top 10 Proven sires from the April 2012 proof run.  Of course we all know that the genomic young sires will have higher breeding values, but we need to account for the expected drop.  Our analysis of the NAAB genomic sires’ proofs vs. their later daughter proven proofs currently shows a 13.8% drop on TPI.  (Note: we are actually tracking the drop on LPI sires, TPI sires and PLI sires, and so far we see them dropping 9.7%, 13.8%, and 13.5% respectively.)

The following table shows where the current top genomic sires would rank compared to the proven sires options available currently.

[csv2table source=”” icons=”true”]

What Does This Mean?

What you notice is that three of the top current genomic young sires (Numero Uno, Supersire, and McCutchen) would all rank among the top 10 proven sires.  In fact, 25 of the top 50 sires would be genomic young sires.  This is not to say that they will all drop the 13.8% that the average sire has already.  They could drop more or less.  However, what it does show is that these young genomic sires have a much higher predictability than in the past.  You can now use a group of these young sires with much greater confidence than in the past.

The Bullvine Bottom Line

Are all the top genomic sires, going to end up on the top of the proven sires list, when they have daughter progeny?  No, of course not.  But what we have been finding is that only about 10% of them drop off the top list, and many of them hold pretty strong.  We have even found some genomic sires that actually go up with daughter information.  What it does mean?  Use genomic sires that are within 10% of the top sires.  If they have GTPI values of 2,300 or greater, you will end up ahead of where you would have been, if you had not used any genomic sires at all.  Just remember this is an average.  The movement will not be exactly the same for all sires, hence the need to spread out your young sire usage.

For all those old school breeders, who are pissing on genomics, well what can I say?  I don’t expect to change your mind. However, it is foolish to piss on something that you don’t understand.  Might I recommend that you read our free guide – The Dairy Breeders “No BS” Guide to Genomics.

There is no question that strong maternal bloodlines are the foundation of any good breeding program. But what top female possesses the best bloodlines and what bloodlines are the ones to watch in the future? In order to determine this, we looked at the top GPTI, GLPI, Polled, and Red cows and heifers. The following is our analysis.

Top GTPI Cows

Leading the way is LADYS-MANOR PL SHAKIRA VG-85 2YR-USA is also a full sister to the #1 Genomic Sire in the breed, Ladys-Manor Shamrock. She and her full sister LADYS-MANOR PL SHANDRA-ET VG-85-2YR-USA, who is #4 on the list, are from the seventh generation bull mother, Ladys-Manor Ruby D Shawn. The most impressive sire stack on the list (#6) goes to SULLY PLANET MONTANA-ET whose sire stack of Planet x Shottle x Justice x BW Marshall leads the way. Montana is also the most genomically gifted on the list, just slightly edging out the extremely popular genomic bull mother Shakira and AMMON-PEACHEY SHAUNA-ET.

[csv2table source=”” icons=”true”]


Top Genomic LPI (GLPI) Cows

Planet daughters dominate the list occupying the top 17 spots and 23 of the top 25. Topping the list is COMESTAR LAUTAMIRE PLANET who is from the Laurie Sheik family. She combines a solid sire stack and genomic values with a maternal power that is the Laurie Sheik’s trademark. The most impressive sire stack on the list goes to the SULLY SHOTTLE MAY daughter SULLY PLANET 935-ET VG-86-2YR-CAN who combines Planet x Shottle x Oman x BW Marshall. When it comes to genomically gifted, none can top ALEXERIN OMAN 993. This Justice daughter has DGV LPI of +3395, which is almost 2000 LPI points higher than her parent average.

[csv2table source=”” icons=”true”]


Top GTPI *RC and R&W Females USA

Setting the pace is KHW SHAMROCK ARALYN. This Shamrock daughter is from the popular RC bull dam KHW Goldwyn Aiko VG-89-USA and is among 6 Shamrock daughters to top the list. In fact, the top three spots are all trace back to Kamps-Hollow Altitude-ET EX-95-USA 2E DOM, who has had every bull she put into stud return to active service and is also the dam of the 2010 World Red Holstein Champion, KHW Regiment Apple-Red. This family has dominated the Red and White scene, demonstrating that they can get it done in the show ring as well as with genomics. The genomic leader of the list is CURR-VALE OBSERVER DELTA-ET. This Observer daughter traces back to Pineyvale Outside Apple another cow family that has it all, type, numbers and red factor. The strongest sire stack on the list belongs to MD-HARMONY SMRK CHRIS V1-E, Shamrock X Gold Chris X Shottle.
[csv2table source=”” icons=”true”]


Top GTPI Polled Females USA

There seems to be nothing more popular these days than polled genetics (read They’re Sold On Polled) and, with that, the demand for genetics from chart topper VER-HAGES TNT SABLE-P-ET could not be higher. This daughter from the Glen-Drummond Splendor family possesses an impressive sire stack – Shamrock x Lawn Boy x Lou – with strong genomic values. The only member of the list to surpass Sable-P for genomics is HICKORYMEA MANOMAN OPINE-P who also poses the most impressive sire stack on the: list Man-O-Man x Shottle x Bosco.
[csv2table source=”” icons=”true”]


Top Genomic Females in the U.S.

Shamrock daughters dominate the list with 18 daughters of the top 25 being sired by this outstanding son of Ladys-Manor Ruby D Shawn. Leading the way is a pair of Shamrock full sisters from the Genomic powerhouse herd De-Su. In the number one spot is DE-SU 1438-ET followed by DE-SU 1439-ET at #2 and not to be forgotten is DE-SU 1451-ET who is #6 on the list all from the popular genomic family Clear-Echo Hershl D Rac-822. In fact it’s 1451 that possesses the highest genomic values in the family. This family has proven to be genomic giants and, with these members topping the list, demand just continues to grow. Of interesting note is the 4 animals on the list owned by Select Sires (S-S-I SHAMROCK MENNA7392-ET, S-S-I SHAMROCK MAGIC7368-ET, S-S-I MOGUL MAYHEM 7963-ET, S-S-I SNOW MALENA 7514-ET) demonstrating this AI center’s strong desire to produce their own genetics (for more read Should A.I. Companies Own Females).
[csv2table source=”” icons=”true”]


Top GLPI Heifers

Similar to the US list, the CDN list is also topped by a pair of full sisters, Velthuis SG Snow Event and Velthuis S G Snow Evening. These Snowman daughters are from the Whittier-Farms Lead Mae family who has 6 daughters in the top 25. Event and Evening are from the extremely popular bull mother Calbrett Planet Eve VG-CAN-2YR. In fact, it’s interesting to note that 16 of the top 25 females come from three main families, (Lead Mae, Lila Z and Gypsy Grand). The Event and Evening sire stack of SNOWMAN X PLANET X SHOTTLE is also the highest on the list. With a DGV LPI of 4406, the split embryo sisters Event and Evening are also the highest genomic females on the list.

The Bullvine Bottom Line

No matter how you look at it, when marketing top females, it comes down to their genes. Whether you are looking at LPI or TPI, genomics has put the spotlight on the females that truly have the best genes.
