Seventy crossbred (Yorkshire (Y) x Landrace (L)) sows parity 1-5 were randomly assigned to Prolan oil S (experimental group) and placebo treated (control group) on day 3 post weaning. They were mated twice when observed in heat. It was showed that the interval from treatment to mating was shorter in treated than those in the control (4.5 +- 5.8 days VS 15.6 +- 27.8 days; P<0.025). Reproductive performance of the sows from the 2 groups were similar. Furthermore, the interval from weaning to subsequent estrus was also similar, 18.3 +- 18.3 days VS 14.6 +- 8.6 days for treated and control animals, respectively. The findings indicated the possibility of using Prolan oil S for fertility control in post weaning sows.
