Extract

Recognition of the importance of the native sheep breeds as one of the main source of meat in Iran has led to several studies on their growth performance. There is little information available on the animal potential of Sangsary sheep, a native Iranian breed. The aim of this trial, therefore, was to assess the growth potential and carcass quality of Sangsary male lambs.

Forty four entire males, 9 month (m.) old, mean initial weight 26.8 (sd 2.5) kg were used. The two diets, which consisted of concentrate and roughage, had a similar protein content (150 g CP/kg DM) and metabofisable energy of either 10.6 MJ/kg DM (diet A) or 9.2 MJ/kg DM (diet B), were each fed ad libitum to 22 lambs. The animals were group penned. At the start and end of the study, the animals were weighed on two consecutive days.
