Abstract

Sixty-three Large White ♂ × (Landrace ♂ × Large White ♀) ♀ gilts were allocated to one of three treatments as follows: (i) boar contact for 20 h/day; (ii) boar influence through a mesh pen division for 20 h/day; and (iii) control, which had no boar exposure.

The experiment started when gilts averaged 156 days of age, and continued until either puberty was detected or the age of 210 days was reached. Analysis revealed significant differences between groups for proportion of gilts reaching puberty (0·76, 0·38 and 0·19), the interval from stimulation to-puberty (10·4, 34·1 and 36·7 days) and age at puberty (167·9, 192·2 and 191·2 days) respectively.
