A top price of 2,700gns was achieved and 12 lots sold for 2,000gns or more when the Goostrey herd of Holsteins and Aryshires was dispersed for Griffiths Farming, Cheshire.Second generation SNP chip available ‘in months’
WHILE the advancement of ‘SNP chips’ has driven genomics in recent years, Jerry Taylor, Animal genomics professor at Missouri University, USA, told the British Cattle Breeders Conference audience, less may be more.
The first generation chip looked at 50,000 locations on the DNA chain, while the second generation (available in a few months) will do 780,000. The masses of information generated by those chips, and the work to find how much of that information was relevant, meant the future could mean only a 100 SNP chip.
Dr Taylor says he was working on breed specific and trait specific chips, to create highly accurate tests for tenderness in an Aberdeen-Angus, for example.
A total of 384 were in development for the Angus, Limousin, Charolais, Hereford and Simmental breeds.
