Seasonal Anestrus — Problems and Perspectivesnvironmental cues to control estrus and ovulation. It also follows that the responses to these cues to show estrus and ovulation are more forceful and distinct if they are contrasted with the absence of behavioural estrus and ovulation at other periods.

Light Control of Reproduction in the Ewetime of that light pulse to between 8 and 12 hours after dawn induces ovarian activity within 2 months after the change..This makes it possible to control reproduction in ewes by giving only extra light and without having to use light-proof buildings.

Hypothalamic-Pituitary-Ovarian Responses to Weaning — Retrospective Evidence for the Cause of Lactated rise in baseline. Plasma FSH levels are related to the development of steroidogenic activity and to ovulation rate after weaning. The mechanisms controlling the inhibition of reproduction during lactation are uncertain, but a primary block at the hypothalamic level is evident. Both prolactin and

During two years first oestrus occurred one month later in Texel than in Suffolk ewes. First oestrus occurred at the end of August in Finn-Dorset, mid Septem
