Little change in non-Holstein bull proofs

Guernseys are the only breed to get a new front-runner in the recent non-Holstein bull proofs from DairyCo.



Sniders Option Aaron moves into first position on the Guernsey Merit Index (GMI), while second place is shared between Boskenna Junes Royal Oak and Coulee Crest Luxury Spider.


The leading British Friesian remains unchanged, with Sem 7 ranked number one with a PLI of £133. Irish proven Grietman is second and UK-bred Lakemead Rancher, third.


In the Ayrshires, Brieryside Golden Sand with a PLI of £169 remains font-runner. He is now followed by G Ebdo, ahead of Orraryd which is ranked third.


D J Hulk holds on to his top position in the Jerseys with a PLI of £185. The second spot is taken by new comer Sunset Canyon Anthems Allstar, which offers a good all-round proof and a PLI of £179.


There is huge interest in using non-Holstein breeds in cross breeding programmes as well as for pure breeding, says Marco Winters of DairyCo.


“However, breeders should be reminded they cannot compare one breed’s index with another – when considering a variety of breed options, they will need to apply a conversion formula to make comparisons.”


Breeders should also be aware some bulls are not the breed they seem at first glance. “This may not be important for some breeders but, when a producer wants to avoid Holstein bloodlines, he needs to check the percentage of Holstein in an animal marketed as an Ayrshire or a Shorthorn, for example.


“When checks are not undertaken, they could find themselves using more Holstein than they think.”
