摘要: 对凉山半细毛羊的产毛、产肉性能、繁殖性能、生长发育、生理生化性状、血液蛋白多态性和染色体核型作了全面的介绍。凉山半细毛羊成年公羊体重85.25±3.25kg、母羊48.11±4.13kg;剪毛量分别为6.55±0.12kg和4.12±0.32kg;毛长分别为18.12±0.51cm和15.74±0.21cm;羊毛主体细度48~50支。6月龄肥羔胴体重16.83±0.76kg,屠宰率为50.79%。母羊初配年龄为10~12月龄,平均产羔率为111.36%。染色体数目2n=54。在长期的精心选育和当地生态条件的影响下,凉山半细毛羊的生理生化性状产生了不同程度的变化,以适应凉山地区的生态条件。

Abstract: Some traits and characteristics of Liangshan semi-wool sheep are introduced, such as wool and mutton performance, reproduction performance, growth and development, physiological and biochemical character, blood protein polymorphism and chromosome karyotype. The average body weight of ram and ewe is 85.25±3.25 kg and 48.11±4.13 kg, respectively. The average wool yield of ram is 6.55±0.12 kg and ewe is 4.12±0.12 kg. The wool length of ram and ewe is 18.12±0.51 and 15.74±0.21 cm respectively. Its main fineness is 48~50 s. The carcass weight of fed-lamb is 16.83±0.76 kg and its dressing percentage is 50.79% in 6 month. The first mating of ewe is 10~12 month and average lambing rate is 111.36%. The number of chromsome is 2n=54. Through long-term breeding, some physiological and biochemical traits of Liangshan semi-wool sheep have changed in order to adapt to higher altitude and lower oxygen-pressure.
