In this information age it is surprising how difficult it can be to get the latest information on proof day.  For that reason the Bullvine has compiled a quick summary of the genetic evaluations from the United States and Canada.


  • DE-SU OBSERVER debuts as #1 gTPI sire in the USA.
    Call it validation or even redemption but, if Observer’s first proof had him falling drastically, it might have put the industry back a few years.  With over 195 sons already being sampled, there is no question that the industry could not afford to have him not achieve a successful daughter proven proof.  Fortunately for all, he not only held his most recent (December 2012) genomic index, but he actually went up.  The biggest change in his numbers was an increase of 142 lbs. of milk, while maintaining his component percentages.  Observer also saw significant increases in his type composites, something the breeders who had been milking Observer daughters had already been forecasting.  While he still needs to be protected on body depth and F&L, he is now over 3 points for udders and has a solid score for rumps.

  • ZAHBULLS UNO GULLIVER new #1 gPA TPI Sire in the USA
    While there were not many new sires in the top gTPI list other than Observer, the same is not true for the gPA TPI list.  Leading the way is ZAHBULLS UNO GULLIVER (Though Supersire may still be the #1 gPA TPI available sire at this time).  GULLIVER is a NUMERO UNO from a DORCY then Toystory and Rudolph.  His dam ZAHBULLS DORCY GLAMOUR was fresh in December and is yet to be classified.  His 2nd dam JOHNAN TOYSTORY GLITTER is classified EX and has a 4yr record of 29,220 lbs. of 3.5%f 3.0%P.  Look for GULLIVER to sire strong components, especially fat, with solid type.  He will need to be protected slightly on his straight legs and depth of heal, but will greatly improve bone quality and foot angle.  His daughters will not win many shows, but they will be large enough however, they will need protection on body depth.  He will bring loads of genetic potential in the areas of health and fertility, especially productive life.

  • BUTZ-HILL SUPERSIRE 1757 new #2 gPA TPI Sire in the USA
    From the EASTSIDE LEWISDALE GOLD MISSY EX-95-CAN, Supreme Champion WDE and RAWF 2011, family.  Missy could, by the end of this week, also be the 2012 Canadian Cow of the Year (Read more: Eastside Lewisdale Gold Missy: 2012 Canadian Cow of the Year Nominee).  1757 has it all.  He is a Supersire from a Man-O-Man followed by Dolman then Goldwyn.  Look for him to bring a balanced package.  With no real holes in his type breakdown, strong components and very desirable health and fertility traits, he is sure to be on many peoples’ must have list.

  • LADYS-MANOR DORCY AMIRA debuts at #5 gTPI Cow in the USA
    From the same family as the long-standing #1 gTPI Cow, Ladys-Manor PL Shakira, Amira is a VG 86 Dorcy from 85 point Planet.  While from a different line of the Ladys-Manor Delightful Jem family, Amira certainly packs a strong genetic punch.  (Click here to see Top 25 GTPI Cows)


  • BADGER-BLUFF FANNY FREDDIE new #3 gLPI Sire in Canada
    Already having over 2,200 registered daughters born in Canada, Badger-Bluff Fanny Freddie (O Man x Die-Hard) hits the mark with his first official domestic evaluation at #3 LPI.  Coming in almost exactly where his MACE proof and genomic test would have indicated, Freddie’s Canadian proof shows the same strong production as in the USA, with great health and fertility, while needing to be protected on conformation, especially dairy strength.  At just 65% GP or better and only 12 VG 2yr olds in Canada (on 253 daughters), Freddie is certainly not a type specialist, but can give you that great shot of herd life, daughter fertility, and calving ease when needed.  His daughters excel at herd life, daughter fertility, body condition score and production traits from shallow smooth fore uddered mammary systems.  It is recommended that he be used on large framed females, with strong median suspensories.  He breeds a consistent pattern of worky functional daughters that should be robot compatible.  For breeders wanting to move their genetics along quickly, they may consider using a high genomically evaluated Freddie son from a large framed dam.  (Click here to read a full breakdown of the Canadian Holstein Evaluation Highlights – April 2013)
  • END-ROAD O-MAN BRONCO new #6 gLPI Sire in Canada
    Bronco (Oman x BW Marshall) has his first Canadian proof coming in at #6 LPI progeny proven sire.  Like his sire, Oman, he leaves functional cattle but Bronco’s daughters excel at production. He is in the top 1% of the breed for both milk and protein yields.  His daughters have good Dairy Strength and Foot Angle is steep and Heel Depth is deep.  Rear teat placement is slightly wide and udders are slightly shallow which will work well for robotic milking systems.  His daughters are likely the ones milk producers hardly notice as they go about producing large volumes.

  • REGAN-ALH DIPLOMAT #7 gLPI and Highest New Release Sire in Canada
    Regan-ALH Diplomat*RDC (Mr Burns x O Man)  takes the spotlight as the highest young sire graduate this round at #7 LPI and the new leader among red carrier sires proven in Canada.  His dam A-L-H DESTINY has many superior progeny including top sons, Danillo and Goldday, in Europe (Read more: 12 Holstein Sires to Maximize Genetic Gain) and his second dam is none other than Markwell Durham Daisy (Read more: Markwell Durham Daisy – 2012 Golden Dam Finalist).  DIPLOMAT ( Mr Burns x Oman x Durham) has his first proof based on 62 classified and 123 milk recorded daughters. His production and durability ratings are well above average and he earns the distinguished Class Extra rating.  Care needs to be taken, as he is slightly below average for milking speed and calving ability.  He will likely qualify as a sire of sons mating sire, especially for red.
  • SUNTOR JOYRIDE new #1 gPA LPI Sire in Canada
    JOYRIDE is from the same family as Oconnors Jay, as his 2nd dam OCONNORS GOLDWYN JASMINE EX-92 is the Goldwyn sister to Jay (Read more: The Bloom is On  Oconnors Goldwyn Jasmine).  His dam SUNTOR MAN O MAN JELENA VG-2YR sold for $30,000 in the 2012 Sale of Stars (Read more: Genomic Stars Shine at Sale of Stars), a steal for a cow that has proven she can throw extremely high genomic progeny.  No doubt the commission from semen sales on this one will be larger than the sale price of the dam.  Joyride, sired by Epic, offers extreme production (+106 kgs protein) from outstanding type with strong health and fertility traits.  With a DGV of +19 for conformation, there is no question that Joyride will leave you those nice sharp cut calves that will draw attention and top dollar at all the genomic sales in a year’s time.

  • MAPEL WOOD M O M LUCY new #2 gLPI Cow in Canada
    The highest newly indexed cow this round is Mapel Wood M O M Lucy, arriving at #2 GLPI right behind her maternal sister, OConnors Planet Lucia, who stays firm at #1 GLPI.  Lucia and Lucy are daughters of Comestar Goldwyn Lilac (Read more: Comestar Goldwyn Lilac: 2012 Canadian Cow of the Year Nominee and Genetics By Design – Crosses the $4,000,000 Mark) with Lylehaven Lila Z as grand dam.

  • RI-VAL-RE SUPRSRE NIKK new #1 gPA LPI heifer in the World!
    Nikk jumps almost 200 LPI points and takes over the coveted #1 spot.  Powered by her dam’s sire, Observer, who debuts at #1 gTPI, Nikk leads a pack of Supersire daughters that top the LPI list.  Her dam RI-VAL-RE OBSRVR NIKKI is due this month and looks very promising for  Ri-Val-Re (Read more: Breeding Ri-Val-Re: Where looking good in the stall is just as important as looking good on paper).

The Bullvine Bottom Line

Some might call it a quieter round in North America, with only one new top proven sire in the US and many of the new Canadian sires already proven in the US.  However, this round is certainly an emphatic validation for the different proving programs.  The fact that Observer came out where he did validates the genomic evaluation system.  Additionally, having many sires that receive their official proofs in Canada matching the US MACE conversion also validates the Interbull MACE system.  Many new genomic sires were released this time, providing   terrific opportunities to discover the next Observer.
