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.
