Analysis and Utilization of Germplasm Characteristics of Ganjia Sheep
The physiological indexes,production performance,wool quality and reproductive performance of Ganjia sheep were systematically studied and analyzed in this experiment.The results showed that Ganjia sheep had a good adaptability to the special environment of high cold and hypoxia.The function of heart and lung was stronger,and the frequency of respiration and pulse was faster.The average body weight,height and length of adult ram were 56.80 kg,74.65 cm and 80.35 cm respectively,the average body weight of adult ewes is 46.62 kg,the average body height is 71.96 cm,the average body length is 79.34 cm,the average wool yield of adult rams is 1.38 kg,the average wool yield of adult ewes is 1.13 kg,and the average length of Braid of adult rams is 30.26 cm,the average of adult ewes was 29.18 cm,the average net wool rate of adult rams was 66.37％,and that of adult ewes was 68.69％.Under the condition of year-round grazing,the body weight before slaughter and carcass weight of Ganjia sheep were 47.70 kg,24.03 kg,the slaughter rate was 50.38％and the net meat rate was 33.6％.The body weight before slaughter and carcass weight of adult ewes were 42.6 kg and 20.85 kg,respectively.The dressing rate was 48.86±3.10％and the net meat rate was 32.95％.The analysis of production performance showed that Ganjia sheep had good genetic characteristics.
