Study finds pregnancy genes
A Dairynz scientist has discovered why some cows are better at getting pregnant than others.
After examining more than 20,000 genes over the past three years as part of her PHD, Caroline Walker found that about 1500 of them affecting the uterus were altered cows.
Ms Walker’s research involved New Zealand and United States holsteins.
Dairynz principal scientist ( animals) Dr John Roche said Us-type dairy cows were less likely to get pregnant in the Kiwi
pregnant pasture-based system.
‘‘ Caroline’s work shown us some of reasons why.
‘‘Basically the New Zealand cow is better at establishing pregnancy and now she’s identified some of the genes which determine this,’’ he said. has the
