Abstract

Sixty-one sows and gilts, selected from a herd with a mean gestation length of 114±1.6 days. were allocated randomly on day 113 of gestation to three treatment groups as follows: (l) 175 μg
cloprostenol, (II) 175 μg cloprosenol diluted in 2 ml sterile distilled water and (III) untreated control. Of the treated animals (Groups I and II). 73% farrowed within 30 hours Farrowing during day-time (0700-1700h) occurred in43%, 63% and 36% of Groups I , II and III respectively Farrowing induction had no effect on duration of farrowing, interval between birth, incidence of dystocia, piglet viability at birth and during the four weeks to weaning. litter size and piglet weight at birth and weaning' Results indicate that cloprostenol can be used to induce farrowing without any ill effects.
