In some cows, the corpus luteum (yellow body)
fails to regress towards the end of an oestrus
cycle. The result will be a continuous production
of progesterone and thus preventing the cow to
get in heat.
This condition is usually associated with uterine
infections, including pyometra, in the early post-
partum period.
