Heifer Livability: The new trait was released in December, but 99% of the attention went to the simultaneously released Feed Saved trait. Of course, we have been getting used to Cow Livability for a while, but it is still worthwhile to reflect on Heifer Livability for several reasons.
First, the trait is the first to target a period that is otherwise largely neglected by the genetics industry. Calving and stillbirth are traits developed to genetically improve the first few hours of life, and Heifer Conception Rate improves that first breeding. But we didn’t have a national trait that genetically aims to increase the chance of survival from calf to breeding.
Good data – and a bit of buzz
