A review of uterine involution and ovarian activity during the postparturient period in the cow.
1970
Abstract Extract In order to utilize spring growth efficiently under a system of grassland farming, a New Zealand dairy farmer endeavours to calve as many cows as possible within a four to six weeks' period. To maintain this calving pattern, herd members must conceive by 70 to 80 days after calving. Consequently normal postparturient uterine involution, together with a minimum of delay in the onset of ovarian activity and oestral cyclicity, is of vital importance. A study of these phenomena may be very rewarding in helping to achieve optimal reproductive efficiency.
