    Column:Pig Time:2021-01-12

    Abstract: Pregnant sows with the same breed and weight were randomly selected and allocated to 2 treatments groups designed as follow: a control and AMPs 0.5%, respectively. The sows were fed with a commercial feed mixed with AMPs at 0 and 0.5% for ten weeks. Sow reproductive performance was recorded during ten weeks and the results showed that the stillbirth rate of sows fed with AMPs in diet showed greatly reduced and the effect was obviously found when used in a longer period.
