|Journal||Applied Animal Behaviour Science|
|Abstract||Sows were infused with corticotropin (ACTH) at 1 IU/kg body wt per day in 1 litre saline, or with the same volume of saline, from the 104th day of gestation. In piglets from both groups of sows, blood cortisol decreased significantly after birth, while glucose increased within 2 h. The total number of aggressive acts was significantly higher in pigs born to control than in pigs born to ACTH-treated sows. Time between birth and sucking was slightly less in pigs from ACTH-treated than in those from control sows. It is concluded that ACTH reduces the rate of agonistic interactions and tends to reduce the time required for first-time successful sucking..|
