摘要/Abstract

摘要： 本试验选用20头6月龄的辽宁绒山羊，平均体重约为16 kg，完全随机分为半胱胺组和对照组。两组饲喂的基础日粮一样，半胱胺组每周添加1次半胱胺，剂量为100 mg/kg，制成颗粒料一次性饲喂；试验期60 d。研究半胱胺对绒山羊产绒性能的影响。结果表明，半胱胺组绒自然长度、毛自然长度、绒伸直长度、毛伸直长度较对照组显著提高（P<0.05 ）;半胱胺组绒、毛强度，绒、毛伸度较对照组显著提高（P>0.05 ），半胱胺组绒毛细度比对照组显著降低（P<0.05 ）;半胱胺组粗毛细度比对照组显著提高（P<0.05 ）。因此，日粮中添加半胱胺可以改善辽宁绒山羊绒毛的品质。

Abstract: Experiments were conducted with twenty six-month old Liaoning cashmere goats with average live weight of 16 kg.The experiment was composed of two groups,there were cysteamine group and control group repectively.Each experimental group was feed by the same basic diet.The cashmere goats in the control group was only feed with basic diet,while the CS group feed with the basic diet added with cysteamine 100 mg/kg W.B. one time every week.Effects of cysteamine on the physical quality of down and hair in cashmere goats was studied in the experiment.The periods of experiment had sixty days.The results showed that CS group of down lengh and hair lengh,down stretched length,hair stretched length were significantly higher than those of control group (P＜0.05).Compared with control group,down strength and hair strength,down elongation and hair elongation of CS group there were no significantly different than those of control group (P＜0.05).The results indicated that the cysteamine made better the cashmere quality of cashmere goats.
