NOVAK Proof Impacted by Addition of Daughters from United Kingdom

PLAIN CITY, Ohio, May 5, 2016-7GU446 Lang Haven Grumpy NOVAK, former No. 1 PTI proven sire, added 38 daughters from the United Kingdom that had a major negative effect on his April 2016 sire summary data. Based on genomic data and the performance of 37 daughters in 27 herds in the U.S., NOVAK's proof would stand at +1,123 Milk, -.09% Fat, +34 Fat, -.01% Protein, +34 Protein, +3.1 Productive Life (PL) and +.5 Daughter Pregnancy Rate (DPR). This data is supported by an extreme yield deviation of +1,602 Milk, +48 Fat and +44 Protein compared to herdmates which is significantly higher than the MACE proof data that includes the U.K. daughters.

"Historically, we have found that MACE proofs including U.K. and Guernsey Isle data have negatively impacted pounds of milk and positively impacted fat percent when compared to the U.S.-only daughter data," reports Blaine Crosser, Guernsey sire analyst at Select Sires Inc. "Contrary to the MACE data, NOVAK daughters are high-production cows that are impressing breeders around the country. Using the U.S. daughter data only, NOVAK would remain the breed's highest PTI sire at +104 rather than dropping to No. 6 on the April active A.I. list. NOVAK will continue to be used as a sire of sons for the Select Sires Program for Genetic Advancement™ (PGA™) sampling system. We provide this information to help our Guernsey customers understand the change in NOVAK's proof."
