Abstract

Forty Large White × (Landrace × Large White) gilts were allocated by litter to one of four treatments, such that one gilt from each of 10 litters was on each treatment. The treatments were: (i) 30-min daily boar exposure; (ii) 30-min daily pen change; (iii) 30-min daily pen change, plus exposure to boar urinary pheromone; and (iv) a control, subject to no stimulation.

The treatments commenced at a gilt age of 165 days and continued either until puberty was detected or a cutoff age of 250 days was reached. Analysis revealed no significant differences between any groups for age at puberty or ovulation rate (determined at slaughter following the second oestrus).
