Summary:

Although intensive husbandry is increasingly applied to sheep, most sheep production around the world is still based on the extensive system. Under these conditions, attempts to improve productivity must take particular account of reproductive and developmental behaviour, as successful sheep production depends heavily on optimal reproduction and development. These topics are presented in this anthology of selected publications on sheep behaviour. The papers have been taken from ten years of Applied Animal Ethology (now Applied Animal Behaviour Science) from its inception in December 1974.
