本文使用了40只不同年龄的母羊,通过一个对比试验,研究了陕北白绒山羊的精料补充料。结果表明,试验组比对照组在绒长、体高、体长、胸围、产绒量、体重、毛长等7个性状方面差异性显著。试验组的产绒量高于对照组80克以上。并实施了陕北白绒山羊精料补充料的推广试验,进行验证,显示出使用陕北白绒山羊补充精料补充料的羊只体格明显增大,体重增加,繁殖能力增强、生产性能提高。建议对陕北白绒山羊补充精料应该在陕北进行大面积推广,以增加羊农经济收入。
In this paper, 40 ewes of different ages were used, and a comparative experiment was conducted to study the concentrate supplements for the white goats in Shanbei. The results showed that there were significant differences between the experimental group and the control group in seven traits of cashmere length, height, body length, chest circumference, cashmere yield, body weight and length of hair. The amount of cashmere production in the experimental group was higher than 80 g in the control group. And the implementation of the North Shaanxi cashmere goat fine feed supplement test to verify that the use of cashmere goats in northern Shaanxi supplemented with refined feed material significantly increased physical fitness, weight gain, increased reproductive capacity, improved production performance . It is suggested that the supplementary concentrate of white goat goats in northern Shaanxi should be popularized in a large area in northern Shaanxi so as to increase the economic income of the sheep farmer.
