Abstract

SUMMARYThree husbandry systems were used to promote differential live-weight gains in 603 Cyprus Fat-tailed, Chios and Awassi ewes. Ewes on the high level of feeding had heavier litters than those on the medium and low levels. Litter size was not affected by level of feeding during pregnancy. Milk production was highest (P < 0·01) for ewes on the high level. The milk production of Chios and Awassi ewes was similar on the high and low feeding levels, but Awassi ewes outyielded both other breeds on the medium level. Chios ewes had larger and heavier litters (P < 0·01) than both other breeds. The correlations between live weights during lactation and milk yield were low and negative indicating a tendency for body loss at high yields.
