Have a heifer that calved her first calf 5 months ago. Took her to get palpated and open. Have not seen the bull on her but thought maybe while I was at work he did his majic. So 3 days ago I pulled her calf off of her and tonight I get home and my bull has her off alone doing his majic. Anyone had a situation where a cow didnt go into heat while having a calf nurse?
