摘要
试验选用24只,平均年龄(15±1.5)月龄、平均活重(32.92±2.33)kg半同胞羯羊,随机分为4组,分别埋植0、2、4、8 mg/kg BW褪黑激素(MT),研究MT对内蒙古白绒山羊生绒期产绒性能的影响。结果表明:绒萌发前约一个月(夏至)埋植MT显著提高了血浆MT浓度,使羊绒萌发时间提前,绒长度增加、产绒量提高,而对绒纤维细度和粗毛生长没有影响,同时确定MT适宜剂量为2mg/kg BW。
The experiment was conducted to study the effects of melatonin on cashmere performance in Inner Mongolia white cashmere goats during the cashmere growing. Twenty-four half-sib castrated male goats （15±1.5） months, （32.92±2.33） kg were divided randomly into 4 groups and subcutaneously implanted respectively with melatonin implants 0, 2, 4, and 8 mg/kg BW. The results showed that treatment with melatonin implants clearly increased plasma melatonin concentration about one month before cashmere growing （the summer solstice）, ahead of time cashmere growing, prolong cashmere and increase production. However, it was no effect on guard hair length and cashmere diameter. And besides, the appropriate dose of melatonin was 2 mg/kg BW.
