Abstract

Two studies were carried out at a commercial piggery. In the 1st study, the sexual behaviour of 24 boars of known breeding performance was observed. There was a correlation between the number of times the boar nosed the sides of the female and the CR achieved (0.48, P<0.05). In the 2nd study, 68 sows housed singly or in pairs were artificially inseminated without contact with a boar or were briefly courted by a boar prior to AI. For sows housed singly and in pairs, the CR after courting was 50.0 and 86.7% resp. (P<0.05) and litter size averaged 6.67 and 10.31 (P<0.05). Corresponding results for sows inseminated without courting were 66.7 and 62.1
