The following question is based on AI done with sequencing and/or using AI drugs of any kind.
I'm not so sure females that take first time AI consistently are necessarily more fertile, due to the possible need for the AI drugs to get pregnant. I say this as the vet mention that older cows and higher BCS produce less hormones and that makes it harder to get them settled. If you use hormones on them to get them AI"d, there's no true way to know if the animal "required" the hormones or was capable of getting settled via bull consistently without aid of hormone injections.
Your thoughts please.
