Abstract
Twenty-four to 36 hours after farrowing, 192 sows were treated with a single intramuscular injection (2 ml per animal) of a prostaglandin analogue; 102 were treated with cloprostenol racemate and 97 with dinoprost tromethamine, and 90 were left untreated. There were no statistically significant differences between the groups in the percentages of sows that came into oestrus by eight days after weaning or conceived by eight days after weaning. Significantly more piglets were born per litter (10.71 and 11.00 piglets in the cloprostenol and dinoprost groups, respectively) and born alive (10.22 and 10.41, respectively) than in the controls (9.24 piglets born per litter and 8.66 piglets born alive).
