本文采用对比实验方法对陕北白绒山羊的专用饲料添加剂进行了研究,试验通过对供试羊子绒长、毛长、体高、体长、胸围、管围、体重和产绒量以及繁殖等性能的观察测定,并对专用饲料添加剂进行了扩大试验。实验数据用SPSS软件进行方差分析和差异显著性检验。结果表明,试验组各性状明显高于对照组,以1.5岁母羊为例,试验组比对照组的体重平均高出5.3kg,产绒量平均高出85g以上。可见,在陕北白绒山羊的饲料中添加饲料添加剂,对白绒山羊的绒长、体重、产绒量和繁殖率等性状的表现有很大影响。陕北白绒山羊专用饲料添加剂为陕北白绒山羊生长发育、繁殖和生产提供了全面的营养,解决了白绒山羊全舍饲条件下微量元素和维生素的缺乏问题,是增加羊农经济收入的重要途径之一。
In this paper, comparative experiments were carried out to study the special feed additive of Shanbei white cashmere goat. The experiment was carried out to test the performance of the feed for the goat cashmere, length, body height, body length, bust, tube circumference, body weight and cashmere yield, The observation and determination, and special feed additives were expanded test. The experimental data using SPSS software for analysis of variance and significant difference test. The results showed that the traits in the experimental group were significantly higher than those in the control group. Taking the 1.5-year-old ewes as an example, the body weight of the experimental group was 5.3kg higher than that of the control group, and the average cashmere yield was 85g or more. It is obvious that adding feed additives to feed of Shanbei white cashmere goats has great influence on performance of cashmere goat such as cashmere length, weight, cashmere yield and reproduction rate. The special feed additive for white goat goats in Northern Shaanxi provides comprehensive nutrition for the growth, reproduction and production of the white goat goat in northern Shaanxi and solves the problem of the lack of trace elements and vitamins under the condition of full feeding in white goat, One of the important ways.
