摘    要:将12只阿帕克孕驼随机分为4组,通过简易的外科手术在羊驼绒毛生长较慢时期(2~5月份),在其颈部皮下埋植褪黑激素(MLT)缓释剂,埋植量分别为0、50、100、150 mg,探讨MLT对试验期羊驼绒毛生产性能的影响,寻求较为经济、可行、实用的促绒途径。研究结果表明:MLT显著增加了羊驼绒毛的直径与伸直长度。各处理组在试验期绒毛生长速度均显著提高,但褪黑激素对羊驼采食量及净毛率均无影响。从整体效果来看褪黑激素对羊驼可以起到很好的促绒作用,100 mg为最佳埋植量。

关 键 词:褪黑激素  绒毛性状  孕驼

Abstract:In order to study how MTL affecte alpaca fleece growth at the slowest growth period of fleece(2~5 month),12 pregnant alpacas were injected melatonin(MLT) by 0、 50、100、150 mg from Feb to May.The results showed that MTL caused diameter and stretched length increased significantly.During the experiment the fleece growth rate in treated groups was increased significantly,but MTL had no effects on picking amount and percentage of scoured wool rate.Above all,MTL played a great role in increasing alpaca fleece growth and 100mg was the best dosage.
Keywords:MLT  Performance of fleece  Pregnant alpaca
