Summary

Seventy-two Cyprus Fat-tailed and Chios ewes with their lambs were used over a 2-year period to study the effects of three suckling regimes on the lactation performance of ewes and growth rate of lambs. The regimes studied were continuous or 24-hr a day suckling, 12-hr suckling and no suckling. The lambs were weaned at the age of 10 weeks. All the ewes, including those suckling, were handmilked throughout the trial twice daily.

Highly significant differences in milk yield (milk sucked by lambs plus milk withdrawn by hand) and lactation length were found between the Fat-tailed and Chios ewes, the respective average milk yields being 159 and 265 kg and the corresponding lactation lengths, 158 and 209 days. There were no significant differences between breeds in the live weight or average daily gain of lambs up to the age of 20 weeks. Suckling for 12 rather than 24 hr a day had no adverse effects on the milk yield of ewes or the growth rate of lambs. The no-suckling regime, however, adversely affected milk yield and lactation length but the effects were less pronounced for the Chios breed.
