Extract

Efficient management techniques in sheep production must take particular account of the pattern of reproductive behaviour and its application in the manipulation of reproductive processes. Conventionally in the UK, the advancement of the breeding season has been achieved by the use of progesterone-impregnated sponges and pregnant mare's serum gonadotrophin (PMSG). The ‘ram effect’ has been shown to be a powerful and cheap way of controlling the time of mating of sheep. The objective of the present study was to investigate the value of using different methods of teasing for the stimulation of ovarian activity in an early lambing flock.
