Abstract

At day 112-113 of gestation a prostaglandin F analogue, Etiproston, was administered intramuscularlyinto the neck of sows as follows: 0.85mg in 10 sows (Group A), 1.7mg in 20 sows (Group B), 3.4mg in 10sows (Group C), and 2ml of a placebo in 10 sows as the control. The time periods from the drug administrationto the start of parturition were 49.1±30.4hr, 28.0±14.8hr and 27.0±4.5hr in Groups A, B and C, respectively, and those of Groups B and C were significantly shorter (p<0.05) than that of control group (56.7±27.6hr). No adverse effects were observed on either the health of the sow and piglets or on the subsequentbreeding capability of sows.
