It’s in her genes…..

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.

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.

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.

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.

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).

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.

What the Experts Won’t Tell You about the Future of the A.I. Industry

Having grown up working with the Canadian Association of Animal Breeders, to working directly with some of the largest A.I. centers in the world, to running our own genetic programs that had many top LPI cattle, I have had the opportunity to learn the semen sales and marketing world from a variety of perspectives.  From this frontline view I have never seen as much change as the A. I. industry is now experiencing with Genomics.  With all these changes, the question becomes “What does the future hold for the AI industry?”

Genetic Advantage

It used to be that every artificial insemination center could claim an advantage in a certain product offering.  Semex would claim a type advantage that over the years converted to a longevity value, in order to appeal to the much larger commercial market, instead of just elite breeders looking for the next great show cattle.  ABS global added product lines and partnerships such as Judges Choice to counter moves such as Semex’s and included strong type offering to their very commercial product line.  Every AI center jockeyed back and forth to show how their genetic product offering was different.  Even when they overlapped, they would claim greater reliability or stability based on the country or system of origin.

Then along came genomics and wiped all that out. 

Today when you look at all the major A.I. centers products, you could take the name and stud code off and you would be hard pressed to notice any difference.  They all try to offer a complete product line.  Moreover, with the reliability, and ability to take the system or country of origin out of it, they all have pretty reliable product.  This almost completely eliminates any genetic advantage that any A.I. center has.

It has been very interesting to watch companies like Select Sires take to owning top bloodlines in a big way (to read more check out Should A.I. Companies Own Females?).  This may be the only way that A.I. companies can differentiate their genetic advantage.  Buy owning the top females these genetics companies (at this point, they are no longer just an A.I. company), are able to develop distinct bloodlines that none of their competitors can have.  This is only going to change more when breeders have full access to genomic information in 2013 and may start to sample and prove their own sires.

Think about it.  I remember back when I was working with GenerVations, and Champion hit as #1 in Canada.  We marketed the heck out of the fact that he was the best in Canada.  We relied on the world’s confidence in the Canadian system to promote that this new, small A.I. center had a reliable product.  We blasted that message around the world making sure everyone knew that GenerVations had the #1 in the world.  Because we all knew that there was about a 2-3 year window before competitors would have their own Champion sons, or he would no longer be the top bull.  Today we are looking at an even smaller window of opportunity. .  With new genomics bulls coming out pretty much monthly, things can change in a heartbeat.  The Select Sires program at least gives them 8 months advantage on the sires and total control over the dams (since they own them).  This gives them the ability to offer their customers a distinct advantage by doing business with them.  Some may look at it negatively and yet, from a purely business perspective, it makes total sense.  In the end, it will look like a very shrewd investment in a market in which it   so is hard to differentiate yourself.

Service vs. Price

Therefore, when you can no longer differentiate your company on product, it only leaves you two other options, service, and price.  You are either going to become the Wal-Mart of the A.I. world or you are going to become Nordstroms’s.  Both can exist in the same market place you just have to become extremely great at what makes you different.

If you want to become the Wal-Mart of the A.I. world, you are going to offer the lowest price for a very commercial product.  This means you need to have your production facilities running super efficiently and your overhead at a bare minimum.  This position plays extremely well to commercial producers who are looking for the lowest costs possible.  For years, companies like ABS, Alta Genetics, and Select have battled very aggressively.  Since most of these companies more or less were just selling a commodity, there really was not any brand loyalty.  Since most large herds did their own insemination work, they eliminated the close link that is developed between producer and the A.I. center through the regular visits by the technicians doing the insemination work.  While the major A.I. companies tried to lock in that connection again by offering mating programs and other services, since they all were pretty much the same and, often, not used by producers, they were only able to gain marginal difference.  And like the Wal-Mart model, margins are tight and profits are slim.

Therefore, if you cannot compete on product and you cannot compete on price, that only leaves service.  With the majority of the marketplace doing their own insemination, A.I. companies have to look outside the scope of traditional marketplace to provide services.  While this has been the case for many years in the commercial marketplace, it is also fast becoming the case in the entire marketplace.  While you may be able to get a slight premium when you have the #1 bull, otherwise you will live and die by the quality of service you offer your customers.  We have already seen this happen.  Many A.I. companies have gone to offering many non-genetic products in order to become a complete service organization, rather than just a supplier of genetics.

Also of interest, is how the roles of sales and sire analysts have also changed.  While many have called the modern sire analyst a glorified tail hair puller, they are now becoming more of a breeding advisor mixed with a negotiation specialist.  This is exactly what they have to do.  They can provide insight to breeders about the daughters of the top mating sires and maybe a little insight that his proof will not tell you.  Even more so, they are now the chief negotiator for their A.I. center.  If I were a GM of an A.I. company, I would invest heavily in negotiation and relationship building training for these individuals.  Realistically, unless you run a program like Select Sires, this will be your only way to get the top sires from many breeders.

The Bottom Line

Like most mature market places, there is little room for grey areas when it comes to the future of the A.I. industry and where the major A.I. companies position themselves.  It will take strong action now either to develop very aggressive genetic programs like Select Sires has, or you will need to decide if you are going to be the lowest cost provider or offer the greatest service.  And yes, I know there are many small micro A.I. companies that will be able to turn a profit.  I get that, they are able to keep their overhead so low that they will be able to offer a niche product to small segments of the market place.  However, when it comes to the big players, they need to ask themselves, “Am I going to get aggressive and develop distinct bloodlines?”  “Are we going to be the lowest price provider?” Alternatively, “Are we going to become legendary for the quality of our service?” Anything that is a smorgasbord of these will only end in extinction in the end.  Don’t think so?  Look what happened to your local hardware store, when Home Depot moved in, or the independent grocer, when Wal-Mart put up one of their super centers in the same community.  Where do you shop today?  Who will be your provider tomorrow?

Has Genomics Knocked Out Hot House Herds?

For years there has been an unspoken awareness that some herds appeared to be able to “work the genetic indexing system.”  These herds clearly understood how genetic indexing systems work in their country and how to manipulate the composition of their herd in order to achieve the highest ranking possible for some top members of the herd.  It was possible to pick these herds out, they had top females and even though they had many sons sampled out of them, seldom were able to produce a top ranking sire, especially for total merit.  This scenario played out in all major countries that use the BLUP (Best Linear Unbiased Prediction) system.  Fast forward to the top total merit rankings since genomic testing has become available.  At first glance it appears there might be a lot less of those animals on the list.  The question is: “Has genomics knocked out all of these animals from the top lists?”

How It Was Done In The Past

First it is necessary to understand what was happening in the past.  Since indexing calculations are based on the variance compared to herd and genetic base, the greater the difference the greater the gain or loss in the result.  Putting that into practice takes two areas: conformation and production evaluations.  The following is a breakdown on how both were done.

Conformation

In order to get maximum results from their genetics programs, many top programs needed to have their top cattle score significantly higher than the other animals scored that same day.  While many people deemed these herds “Hot Houses”, in reality they are just working the BLUP system to get maximum results.  Since the calculations also took into account the genetics of the other animals scored, these “hot house” herds needed to have daughters of high type bulls that would score lower than the selected cattle that were typically sired by bulls with lesser conformation scores.  For example, you have a low value cow sired by a +14 conformation sire that goes 79 points, and a high conformation cow sired by a +6 conformation sire that goes 86 points.  This would provide the selected cow with the greatest difference over the expected value and have significant improvement in their EBV for conformation and thereby in their overall total merit.

It’s in these herds that you may have seen a “good group” and a “bad group” of the herd, with a corresponding difference in management and presentation of the groups.  While it’s normal in any herd to have the high value or “family favorites” get some level of preferential treatment, these herds took it to a new level.  While this sounds bad, in reality it was necessary in order to achieve top rankings.  For the classifier visit the good group was show ready and the bad group was ready to head for beef.  (Though if you read “Tom Byers: It’s Classified” you realize that this really does not make that big a difference for the professional classifier).

In contrast to the “hot house” herds who try to have a high herd average score (for example the average 2yr old score of 83+ points) find it very hard to get high indexing conformation females.  With very little difference in scores from the top to bottom of the herd, there is less herd variance, contributing to a lowering of their overall rankings.  Since these herds where not a cross section representation of the breed population and BLUP treats them as if there were, these cattle actually get somewhat penalized for being a member of a great herd.

In order to have maximum impact, herds wanting to have high index’s needed to have maximum within herd variance. This meant that they have to have a true cross section of the breed present in their herd, as opposed to just the best of the best, like many of these breeders would have liked. It’s also for these reasons why niche type sire sampling programs need to be used in all types of herds not just high conformation breeding programs.

Production

The story is not that different on the production side.  Here the comparisons are for milk, fat and protein yields on a within test day basis.  Adjustments are made for a cow’s age, lactation number, stage of lactation, month / season…etc.

In order to maximize the increase in production genetic evaluations, these “hot house” herds needed to  have underperforming  daughters of high production sires, that were being out produced by the selected females that were typically sired by more balanced sire who’s production index may not be as high.  In Canada, this is where you would see females with very high (i.e. +200 and more) BCA deviations.  Sometimes you would see deviations that were greater than even their herd average BCA.  You ask yourself “How could one cow on the same feed, same treatment, same exact program, produce twice as much milk as another cow?” While it sounds unrealistic, it was necessary in order to gain maximum results.  All breeders have seen cows that can out produce herd mates by 30, 40 even 50%, but when you see them doing more than double (100%) it raises questions in the minds of people with practical cow sense.  Hence why some herds are stamped as “Hot House’s.”

How Genomics Has Changed Things

relative weighting for Direct Genomic Value (DGV) compared to traditional Estimated Breeding Values (EBV)With the introduction of genomic evaluations in August 2009, the effects that any “hot house” efforts can have has been reduced in the genetic indexing systems.  This is because for young cows in first or second lactation, the relative weighting for Direct Genomic Value (DGV) compared to traditional Estimated Breeding Values (EBV) is roughly 55:45 (Source: Canadian Dairy Network).  What that means is that if a “hot house” cow would have had a 300 point jump from these types of efforts, they now would only see a 165 point jump.  While it would still have an effect, genomics has greatly decreased the “hot house” effect. Remember that the female family members of each cow are being re-evaluated as well.  Additionally those females formerly lower on the listings, but that were in herds where practices are normal, could now move up the genetic index rankings.

The other factor that Genomics has brought into play is that, if a particular animal is not gifted with the best genomics her parents had to offer, she will also see a significant drop.  So let’s say that a cow has an EBV-PA of +2500 LPI or TPI, but her genomic panel comes back with a LPI or TPI value of +1500.  That cow would see a drop of about 450 points.  Dropping her  to an LPI or TPI of +2050. This takes her  from being near the top of the list to almost out of consideration.  All this is outside the control of any on-farm practices.  It’s for these reasons I am sure that some owners now get nervous when opening their genomic results letters.  This single test can have the biggest effect on the genetic profitability of any cow.  It can even have a greater effect than the classification.  With GLPI’s and GTPI’s now over 60% reliable, adding animal performance information now has much less influence than in the past.

The Bullvine Bottom Line

The great news is that genetic indexes that contain animal genomic information are not as influenced by preferential treatment or herd variance as traditional genetic indexes are.  Since genomic values are based on evaluations of thousands of cattle in many different herds, in many different environments, and in different countries, the ability of a “hot house” to greatly change results has been significantly diminished.  That is not to say it has been totally removed.  Remember that 45% of the new GLPI formula is still based on an animal’s performance compared to contemporaries.  Therefore, these efforts will still have an effect.  It is for these reasons that you see some previously prominent cows and cow families are now absent from the top female lists.  Am I saying that these cattle may not be great investment?  No, what I am saying is consider these factors when making your purchase decision.  Do your homework before selecting, breeding, merchandising or buying.  GLPI’s, GTPI’s and DVG’s will help you make more informed decisions, but remember they are just a tool.

Should A.I. Companies Own Females?

The debate is back! While Artificial Insemination companies have owned females for many years, with recent dominance by some AI breeding programs on the TOP GTPI list in the US and the upcoming ability for breeders to sample their own bulls, the debate is at the forefront again!

Lessons from the Past

Over the years there have actually been many examples, with mixed results when A.I. companies have owned their own female bloodlines.

  • AltaGenetics
    Back in 2001 Alta Genetics caused considerable  stir when they planned to take their embryo program and convert it into a 1000 elite females test herd to have sires sampled through 100 contracted progeny test herds.  While the program had many supporters from the genetic advancement side, it was seen as very risky and ultimately was put on hold when Alta purchased Network Genetics.  The herd was then dispersed to farms owned by Alta in Canada and Holland and in four independent herds in the U.S.
  • GenerVations
    GenerVations is probably a great example of an A.I. program that has had a lot of success owning their own female bloodlines.  Starting with Albert Cormier’s part ownership of Skys-The-Limit Claire where he was able to maximize profits from both sides, thanks to Champion.  Continued by GenerVations part ownership of Lylehaven Lila Z, owning female bloodlines has been what enables GenerVations to compete on a global scale.  Not being able to have a large sampling program, GenerVations has had to focus on potency rather than volume.  Selecting on the very top bloodlines and putting all your eggs in a few baskets means GenerVations has to take a larger risk than the big A.I. companies.  Owning top females has helped them manage the risk.
  • Genex CRI
    The Genex CRI Genesis program has been around since 1989.  While heavily focused on top Index cattle they have been able to achieve success on the female side with such cattle as MS Pride Plnt Tasket 788-ET who tops TPI and Lifetime Net Merit lists.  On the male side, the Genex program has proven to be very stable in their bull program.  The 54 Co-op prefix bulls averaged a mere $1 drop in Lifetime Net Merit (LNM) as they transitioned from genomic-only genetic evaluations in August 2010 to daughter-proven genetic evaluations in December 2011 (minimum of 40 daughters).  The average change among the 1,879 bulls industry wide over the same time period was a $22 decrease.
  • St. Jacobs ABC
    While the St. Jacobs ABC’s Judges Choice program has been around for many years marketed in partnership with ABS Global. They have more recently entered into the ownership of top female bloodlines with the purchase of Ashlyn, Hezbollah, and Barbara.  Choosing to focus on established show cattle has meant that the Judges Choice program has been focused on young sire sales with sires achieve proven status being an added bonus.
  • Select Sires
    Probably the A.I. Company making the biggest waves today is Select Sires.  Select has been very aggressive in the ownership of top genomic females to the point that on the December Top 200 Genomic Female list they owned 18% of the top 50 new genomics heifers in the US.  With Ladys-Manor PL Shamrock and others, Select Sires is investing heavily in ownership of top genomics females in order to produce the next generation of top TPI Sires.

The Genomic Game Changer

The biggest reason this issue is coming up again is because genomics is changing the prominence of industry sires with no daughter proof data, and virgin heifers are now in heavy demand as for contract matings.  Genomics has deceased the risk to such a level that it can be very economically viable for these A.I. companies to invest in top bloodlines and increase their genetic advancement rate faster than their competition.  By being able to control the matings on these top females and use top (often unproven ) genomic sires on these virgin heifers they will be able to greatly increase their rate of advancement over their competition, and in fact fast than even top breeders.  That is because they will have access to their own top genomics young sires sooner. They  can use them on contract matings far faster than any breeder can.  This gives  them a distinct competitive advantage over both other A.I. companies and over breeders.

The Question of Ownership

A.I. companies owning females seems to be a very touchy issue for many breeders.  While many of these companies are perfectly within their rights legally, it comes down to a question of public perception.  Many companies, such as Semex, have taken a very vocal position that they do not own females.  Given that Semex is a member owned co-operative, it’s understandable that they do not want to be in competition with their breeders, many of whom are the top suppliers of sires to many A.I. companies worldwide.  However, Select Sires is also a federation of nine farmer-owned-and-controlled cooperatives.  You could not have two more extremely opposite positions from two very similarly owned companies.

The Bullvine Bottom Line

Genomics has changed the breeding world.  However, it has also created a wild wild west environment where both breeders and A.I. companies are figuring out what the new world will look like.  Will A.I. companies be nothing more than service companies that deliver genetics from many sources (much like a Wal-Mart) where they are more based on quality of service and customer experience than the genetics they have to offer?  Will more and more top breeders try to increase their own profits and sample their own sires? (Watch www.thebullvine.com for articles on these issues coming shortly)  The important  thing to note is that some A.I. companies have taken early steps to control the source and supply top genetic animals to their customers.  The world is changing and so will  the inter-relationship between breeders and A.I. companies, in many cases they are no longer just a customer they are now a competitor.

The Genomic Advancement Race – The Battle for Genetic Supremacy

In the race to have the next great sire, there comes a point where you have to ask have we taken it too far.  Analysis performed by Holstein International of the 33 popular genomics bulls of 2009 showed that only one has managed to maintain his breeding value: O-Style.  Even with those facts, why are so many A.I. companies now basing 70%, 80%, and 100% of their genetic programs on genomic sires?

Partly due to the “shortage” of new daughter proven sires of sons, and partly due to the increased confidence in genomics since it started in 2009 the percentage of breeding programs that are using genomic sires has increased from 40% to 50% on a global basis.  Moreover, just like a great outlier sire, the difference between the AI’s is substantial.  With Accelerated Genetics, Genex-CRI and Alta Genetics all sampling over 90% genomics sires.

So why are these studs putting so much weight in genomics?  Do they know something the rest of us don’t?  Have they just gone cuckoo?

In reality is actual goes back to the genetic advancement formula that has been around for many years.

Let’s take a close look at each piece of this equation and the effect genomics has.

Accuracy

The effect that genomics has on accuracy is very significant.  According to CDN the average gain in accuracy in LPI due to Genomics is as follows:

Selection Intensity

In the past AI companies would have sample multiple sires from the same cross, and try multiple crosses to find out which one was the genetically gifted.  That does not even take into account the need to sample from a larger portion of the top females to discover which ones where genetically gifted and which ones where “artificial” in their breeding values.  With genomics, they can pre-screen these sires and crosses to see which ones will have the highest chance of producing the next top-selling sire and which ones did not get the best their parents had to offer.

By eliminating the need to sample such a large number of sires, allows the AI companies to focus on a more intense core group of sires, and push the limits on genetics advancement

Genetic Variability

This is one area than many breeders do not pay enough attention to.  Certain traits, such as Milk Yield, Protein Yield, and stature are much more heritable than others (i.e. Rump and Feet & Legs).  What this means is, if you spent all your time breeding for feet and legs, you will see less overall genetic gain than say focusing on production traits.  That is why production sires will typically offer the greatest genetic gain, since most type traits have a much lower heritability.  It’s also why breeders always need to be conscious of production when building your breeding program and don’t mate for low heritability traits.

The following is Holstein heritability estimates used for genetic evaluations in Canada

  • Production Traits
    • Milk Yield 43%
    • Fat Yield  34%
    • Protein Yield 40%
    • Fat Percentage 50%
    • Protein Percentage  50%
  • Functional Traits
    • Somatic Cell Score  27%
    • Lactation Persistency 40%
    • Herd Life  10%
    • Calving Ability 6%
    • Daughter Calving Ability 6%
    • Milking Speed  21%
    • Milking Temperament 13%
    • Daughter Fertility 7%
  • Major Type Traits
    • Conformation 26%
    • Rump 15%
    • Mammary System 25%
    • Dairy Strength 36%

Time

In order to cut down the genetic intervals many AI companies are now using genomic sires themselves as sires of sons.  This means that there are sires of sons that don’t have any daughter information yet.  The company taking this to the extreme is Alta Genetics.  Their breeding program is made up by no less than 70% of genomic bulls that are sired by genomic bulls.  The greater you can cut down the interval from the birth of the parent to the birth of the progeny the greater the average genetic gain per year.Yes, you will run the risk of sires that drop, but overall on a large breeding program you will come out ahead.

The Bullvine Bottom Line

Many AI companies, especially in North America, are pushing the edge with genomics to maximize annual genetic gain.  While they will run the risk of a sire not turning out, or dropping significantly from his pre-proven prediction, when you look at the net result over the generations of their whole breeding program they will come out way ahead.  By leveraging the effect Genomics has on accuracy, selection intensity, focusing on highly heritable traits, and making the interval between generations as low as possible, these studs stand the greatest chance of consistently producing the best genetics available.

If you are like many, this whole genomics thing can be very confusing.  While it might be just simplest to pick the top five genomic young sires.  Who knows what could happen.  In order to get some clarity on just what young sires you should use we took a deeper look at the top 50 genomic young sires available in Canada and here is what we found.

GLPI vs Parent Average

In the past most would have just simply used the top parent average young sires and gone from there.  It’s interesting to see that only one of the top GPA LPI sires (DE-SU PHOENIX 588-ET) would have even been considered a top LPI sire before genomics.

GPA LPI PA-LPI
DE-SU PHOENIX 588-ET GEN-I-BEQ LAVAMAN
GENERVATIONS LEXOR COMESTAR LOBSTER
CABON FERNAND COMESTAR LAUTAMARCUS
MISTY SPRINGS NUMBER ONE DE-SU PHOENIX 588-ET
COOKIECUTTER HEFTY-ET STE ODILE RIMOUSKI

Genomically Gifted

With DE-SU PHOENIX 588-ET jumping to the top of the list, we then wanted to see just who else has been genomically gifted with the best genes his parents have to offer. What we found was the following:

Sire GPA LPI PA – LPI Difference Direct Genomic Value
CABON FERNAND 3239 2492 747 3655
DE-SU ALTAROGERS-ET 2816 2159 657 3167
COOKIECUTTER HEFTY-ET 3211 2591 620 3211
DE-SU ALTAMELHOR-ET 3013 2413 600 3296
SHEEKNOLL ALTAVITTEK 2905 2307 598 3291

Bitch Slapped With the Ugly Stick

Since we took the time to see who was gifted we thought it would be equally important to see what bulls full-out of the ugly tree and hit every branch on the way down.  Here is what we found:

Sire GPA LPI PA LPI Difference Direct Genomic Value
COMESTAR LAUTAMARCUS 2879 3020 -141 2806
GIBBS M-M DENALLI-ET 2913 2909 4 2847
COMESTAR LOBSTER 3048 3020 28 3094
GEN-I-BEQ LAVAMAN 3116 3070 46 3317
GENERVATIONS LINGO 2938 2888 50 2899

(Please note: this does not mean they are totally ugly they are just not as pretty as the could have been)

When in Doubt Go To Sire Stack

One thing I have learned from your tried and true breeders, is whether you are breeding for index or showing, nothing beats a good sire stack.  With that in mind we prepared a 4 generation sire stack of each sire and here is the cream of the crop.

Sire Sire Stack Sire Stack Index
DE-SU PIERRE 649-ET Planet x Bolton x Shottle x Justice 2638
PIROLO SOLEMIO-ET Man-O-Man x Goldwyn x Justice x Jacko Besn 2617
GENERVATIONS ENSIGN Man-O-Man x Baxter x Shottle x Justice 2582
ESPOIR Man-O-Man x Goldwyn x Champion x Jesther 2573
GALLAIS FEELING Man-O-Man x Bolton x Shottle x Trent 2565

Girl Power

The following are the bulls that are getting it done from a strong female (dam) side of their pedigree.

Sire GPA LPI Sire Stack Index Difference
MAPEL WOOD BREWMASTER 3046 1955 1091
MISTY SPRINGS SUPERSONIC 2827 1760 1067
DE-SU ALTAMELHOR-ET 3013 2084 929
LESPEREE GLOBAL 3009 2099 910
MISTY SPRINGS NUMBER ONE 3220 2331 889

The Bottom Line

Depending on your propensity for risk you can take those sires that are the extreme genomically, such as CABON FERNAND or DE-SU ALTAROGERS-ET, or you can go for the sire with great blood lines, such as DE-SU PIERRE 649-ET and PIROLO SOLEMIO-ET.  But as my wife tells me every day, behind every good man is a great woman, so maybe you try MAPEL WOOD BREWMASTER or MISTY SPRINGS SUPERSONIC.
