I know UC-Davis tests for A1 v A2 milk ... but wasn't sure if anyone tested for butterfat.
It's one of the traits included in genomic profiling, and no, I don't know the details.
You could get useful information from ancestral indexes, at low reliability. But probably a lot cheaper than doing genomic profiling.
btw, I'm milking one May daughter, she's a little doll but not sure that she's back in calf. She was the youngest of the group and the grazier didn't grow her out properly, he no longer has a job growing yearling heifers. Have some more to calve next year.
The Murmurs will calve next spring, I'm told they will turn into capacious little cows but based on their growth thus far am not keen to use him again.
Some new faces in the bull selection teams in the top AI companies in NZ and things have changed a little since this thread started, for the better we hope.
