A total of 94 sows were injected intramuscularly at the root of the ear with 0.05mg of Prostaglandin F2αanalogue at 114 days of pregnancy. Twenty control sows were injected with 2.0mlof solvent alone and allowed to deliver spontaneously. The average time of beginning of parturition was 12: 20 p.m. at 115 days of pregnancy in the treated sows and 2: 45 a. m. at 116 days of pregnancy in the controls. The average time required until the occurrence of parturition was 25.77 and 38.67 hours in the treated and control sows, respectively. There was a significant difference in it between the two groups (p>0.05).
The rate of parturition during the working time was 41.5% in the treated group and 30.0% in the controls. The average time required for delivery was 4.18 and 4.39 hours in the treated and control groups, respectively. There was no significant difference in the average number of newborn young, the time required for discharge of the placenta, or the frequency of appearance of abnormality in piglets between the two groups.
