摘要
用简易的外科手术对阿白羊、盖县绒山羊及二者杂交改良型绒山羊在梳绒后于其颈部皮下埋植一种含褪黑素的胶囊，经５周后受试羊群开始长绒，而对照群羊则未见绒生长。在９月中旬天然生绒季节开始时，受试群羊绒已分别长至３～５ｃｍ，而对照群则刚开始生长至２ｃｍ。表明上述各受试群当年被成功地诱发二次生绒。受试群较对照群可提早２个月生绒；当年春季埋植药囊，在８月下旬新生绒可脱落并呈绒花状浮于粗毛上，如不适时采集，则成絮状缠在粗毛或蹭于灌木丛中，自然流失；如适时梳绒则获收成，增加经济效益。但是当年夏季埋植药囊、初秋未行梳绒的受试群（盖羊），于翌年春与正常羊的采绒量相比，其产绒量较正常盖羊提高３４％。本试验进一步表明，在当年春季埋植药囊于秋季二次生绒和采收后，并不影响翌年春的正常产绒与产绒量收成。
Inner Mongolia Albus, Gai and hybridizable cashmere goats were treated with melatonin (melt.) implants in 19 June 1993, end of April 1994. The results showed that the cashmere was initiated to start growing 5 wks later after melt implant, while nothing was happend in the control. Measurement was made on 12 of Sept. and end of April in the next year. The product of cashmere in the treated Gai was increased to 34%. and control group only 6%. The mean maximum length of cashmere was ranged 3～6 cm. for the treated goats and only 2～5 cm. for control Albus and Gai. No significantly chang observed in the experimental animal and control group of Albus white cashmere goats. The cashmere growth of treated Gai was early and faster than control group. The natural loss of cashmere was existed. Melt implant did not influence the quality, quantity, diameter of cashmere producttion neither of treated goats in autumn of current, nor in spring of next year, which is as same as the control one. The control group of goats grew cashmere only during autumn and winter period.
