Abstract: In order to study the economic benefits and social benefits of breeding excellent local sheep breeds, the slaughter test of Sunit bred sheep was carried out. The results showed that the average live weight,carcass weight and net meat weight of Sunit bred ewes and bred wethers were 47.70, 22.50, 17.60 kg and 51.60, 25.00, 19.60 kg respectively. Their slaughter rate and net meat rate reached 47.10%, 36.80%and 48.30%, 38.00%respectively. Their eye muscle areas could reach higher levels, being 13.70 and 15.10 cm2 respectively. The coefficient of variation of net meat weight,carcass weight and live weight were higher and that of bred ewes and bred wethers were 13.46%,12.97%, 10.80%and 8.11%,7.86%, 6.25%respectively.
