摘要:
An AB programme restricted to 14 days through the use of mated, 135 were treated after selection on pre-mating oestrus dates or rectal examination. Treatment was administered on the 6th day of mating. Untreated cows were inseminated, on detection of oestrus, throughout the 14 days. Nine of 135 treated cows were inseminated within 48 hours, 50 at 72 hours only, 75 at both 72 and 96 hours and one at 96 hours after treatment. All cows in season were inseminated, irrespective of recent insemination. Prolonged and split heats, and short cycles (less than 14 days), occurred in treated and untreated cows.
