In dairy cattle, resumption of postpartum cyclicity is a normal process that takes place during the first 30 days in milk where cows ovulate and develop their corpus luteum. This is needed to re-establish the estrous cycle — every 21-day interval with a range of 17 to 24 days — and pregnancy after parturition. Anestrous and anovulation are often used to define cyclicity and cystic cows. However, these ovarian conditions are often triggered by different causes. Let’s define the ovarian conditions.
One important aspect of managing a dairy operation is having successful reproduction from your cows, as this both causes lactation and replenishes your herd. Multiple reproductive conditions in cattle can make it more difficult for farmers to get them bred.
