Abstract

The sexual behaviour of 6-month-old boars and gilts mating in the boar's accommodation pen was compared with that of boars and gilts mating in a mating system called the Detection Mating Area (DMA), in which the boars are housed in individual stalls around a large central arena which is used for oestrus detection and mating. All pigs were Large White x Landrace. Sexual behaviour was observed in a series of 5 min mating tests over an 8 week period, and the long-term effects of these 2 mating systems on the boars were examined by observing sexual behaviour in three 15 min mating tests in a specific mating pen after the 8 week experimental period. Boars and gilts mating in the DMA system achieved a significantly higher number of copulations than those mated in the boar's accommodation pen (9.8 vs. 7.8). This increase in the number of copulations achieved in the DMA system was mainly due to the increased duration of oestrus in gilts in this system (2.7 vs. 2.2 days), while the sexual behaviour of the boars was similar in the 2 mating systems. The increase in the duration of oestrus was possibly due to the increased sexual stimulation received by gilts in the DMA system during oestrus detection. No long-term effects of mating system on the sexual behaviour of the boars were found in the 15 min mating tests.
