Abstract: The present study was conducted to investigate whether nutritional treatments can influence the carcass composition, potential consumer acceptability and cost of rearing, at any defined liveweight (LW) or proportion of breed mature weight (MW), in male lambs of three indigenous Greek dairy breeds of sheep. Two trials were carried out each with 30 weaned lambs (about 42 days) of the Boutsko (B), Serres (S) and Karagouniko (K) breeds. The lambs were reared under different conditions of diet, housing and management and were slaughtered at different degrees of maturity or different slaughter weights. During the first trial, the lambs were individually fed on three levels: high (H), medium (M) and low (L) of concentrate (192 g crude protein/kg DM and 11.3 MJ ME/kg DM) and Lucerne hay (182 g crude protein/kg DM and 8.3 MJ ME/kg DM) offered ad libitum. During the second trial, the lambs were group fed indoors for 63 days on three levels (also denoted as H, M and L) of the same concentrate and Lucerne hay ad libitum, and then finished on irrigated sown pasture (Lolium perenne+Trifolium repens). It was found that in both trials, breed of lambs and concentrate allowances (CA) had a significant effect (P<0.001) both on daily LW gain (g) and time taken to reach the target LW. The proportion of fat in the carcasses of lambs was affected significantly by the breed and LW at slaughter of lambs (P<0.001) and also by the CA (P<0.01) in year 1 whereas in year 2 only LW at slaughter had a significant effect (P<0.05). Lambs finished indoors were fatter than those finished on irrigated sown pasture. The results suggest that manipulation of post-weaning nutrition for the Greek dairy breeds, based on locally available feeds, can be used to produce consumer acceptable carcasses heavier than the traditional from suckled lambs and the marketing period can be extended to avoid the current oversupply at traditional marketing times.
