Abstract

|
To study the effects of oxytocin and three parasympathomimetic drugs such as neostignine, bethanechol, and pilocarpine in reduction of interval between birth and incidence of intrapartum stillborn pigs, 213, sows and gilts which had been kept under the same condition, were randomly allotted to 4 treatment and one control groups. The side reactions of three parasympathomimet ic drug were also examined. The results obtained were summarized as followings.
1. Parasympathomimetic-treated groups revealed tendence to shorter interval between birth than oxytocin-treated or control groups.
2. Stillbirth rate per litter was significantly less (p<-0.01) in the parasympathomimetic-treated groups than in the oxytocin-treated or control groups.
3. Moderato to severe salivation and vomiting were found in many dams of the pilocarpine-treated and bethanecol-treated groups. The neostigmine-treated group showed nearly no side re action and neostigmine found to the safest among three parasympathomimetic drugs.
