Abstract

Behavioural responses can have direct effects on reproduction when the performance of the behaviour contributes to productivity (e.g. achievement of copulation). Alternatively, there are indirect effects where a behavioural change is insufficient to allow adaptation to an environmental change and so the animal has to resort to physiological mechanisms with potential adverse effects on productivity. Boar contact has substantial effects on a number of female behaviours that can directly affect her productivity. Either daily introduction to a boar or continuous housing adjacent to boars is effective in stimulating the onset of oestrus in weaned sows. In addition, daily boar contact is necessary..
