Abstract: | A group of 16 German Landrace sows, nursing 155 piglets, was used for the demonstration of the effect of 20 mg of the progestogen megestrol acetate, administered orally from Day 8 to 21 post-partum, on milk production, milk composition and piglet weight. Eight sows remained untreated. Megestrol acetate treatment increased significantly milk yield by 35% and piglet weight at weaning (Day 35) by 30% over controls. A carryover effect after cessation of drug treatment was dtected, which kept milk production at an increased level for 8 more days. |
