Abstract: The reproductive tract was examined in 17000 ewes (largely Polwarth and Corriedale) slaughtered for meat in 1967-70. A clearly defined seasonal pattern of ovulatory activity was evident, with autumn peaks in both the proportion of ewes ovulating and the incidence of multiple ovulation. A further peak in multiple ovulation occurred-in the relatively few ewes which cycled in the spring. Joining in April/May is therefore recommended for optimal fertility in wool flocks and this recommendation is discussed in relation to ewe nutritional requirements during pregnancy and lactation. |
