| Abstract: | Based on the measurement of the body size and weight of the 150 Jialuo Sheep of different gender at all ages, and the slaughter determination of the adult ram （n=4） and adult Jieyang （n=6）, the results show that the slaughter ratio of adult rams rate is 63.75±3.59%, net mutton ratio is 35.00±0.82%, the body of weight is 37.33±5.05kg, and the flesh and blood ratio is 1：3.91. The slaughter ratio of Jieyang adult is 67.17±2.32%, net mutton ratio is 40.83±1.17%, the body of weight is 32.17±3.25kg, and the flesh and blood ratio is 1：5.15. The regressive equation between the body of weight of the adult ram Jialuo Population and the net mutton weight is y=1.761x＋23.915. |
