Anoestrus
Anoestrus is a condition where some cows do not show heat signs for a long time after calving. In this case, no ovulation takes place. The condition can be caused by an infection or inflammation of the uterus and underfeeding of the cow, especially with minerals.Â
Anoestrus. Cows in anoestrus show no heat activity, because the process of follicle development does not lead to ovulation. Anoestrus is normal in the post-partum cow, but most dairy cows ovulate for the first time within 50 days of calving.
