Question

Why animals undergo postpartum anestrus after parturation

Answer 1

Answer:

for this question i have taken the example of cow to explain..

After calving, cows go through a period of temporary infertility known as postpartum anestrus. Cows will not experience estrous cycles during this time. Another common term associated with this phe‐ nomenon is postpartum interval, which is the time from calving to the subsequent conception. Post‐ partum interval plays an important role in determining a cow's calving interval, or the number of days from calving date in one year to calving date the next year. To maintain a 365‐day calving inter‐ val, a cow must have a postpartum interval of 80‐85 days. If a shorter calving interval is desired to move the cow up in the calving cycle, she must have a postpartum interval of less than 80‐85 days.
