I had a calf that I am unsure of the sire on. AI'd the cow, 2 weeks later put a bull in, SAW her get bred, 30 days later let her run with the commercial cows, and 3 bulls. She just calved.......so 3 possible sires. I looked on the angus web site, but didn't find any info on parent testing. Anyone know how, who to contact, where to look? Thanks!
