Abstract

Five groups of four boars were reared from an early age under various social conditions. The sexual and social behaviour of these boars was studied from 32 to 52 weeks of age. Boars reared in a group from 3 weeks of age achieved a significantly greater (0·10 > P > 0·05 and P < 0·05) number of copulations and displayed significantly more (P < 0·05 and P < 0·05) courting behaviour than boars reared from 3 weeks of age in the absence of either physical contact or of both physical and visual contact with other pigs, respectively. On average, lack of physical contact with other pigs accounted for approximately 70% of the impairment in the copulatory performance of boars reared in the absence of visual and physical contact with other pigs. There were no significant differences between the copulatory performance of the boars reared in a group from 3 weeks and either those reared from 12 weeks of age in the absence of visual and physical contact with other pigs or those that were housed as a group during rearing and the testing period.
