【摘要】 采用测定生理指标,生长发育、繁殖率和生产指标的方法,对从澳大利亚引进的20只安哥拉山羊进行适应性研究。测定结果:这群安哥拉山羊四季的生理指标正常、体重稳定增长、产毛量高、马海毛质量合格;但母羊的繁殖率低,羔羊初生重和断奶重较低。分折研究结果认为,安哥拉山羊能适应陕北的气候条件,但必须充分满足其营养需要,特别是怀孕后期和泌乳期,才能充分发挥其生产性能。更多还原

【Abstract】 With the methods of observing physiological indexes, growth and development, reproductive rate and production targets, 20 Angora goats introduced from Australia into the loess plaleau of north Shaanxi were studied on adaptability. The results showed that, in this flock of Angora goats, physiological indexes in all seasons were normal, weight was growing up steadily, grease—fleece wt. was higher, and the quality of Mohair was up to standard, but the reproductive rate of shegoat, and the birth wt. and weaning wt. of kid were lower. It is considered that Angora goat has a good adaptability to the local climatic conditions of north Shaanxi, but the nutrient requirements in all seasons, especially in the last gestation period and lactation period should be satified in order to give full play to their production performance.更多还原
