四川白鹅活体拔毛产毛绒量测定

DETERMINATE ON FEATHER PRODUCTION FOR LIVE-BODY PLUCKING OF SICHRAN WHITE GEESE

从四川白鹅种群中抽取试验鹅106只，分别进行“成年公鹅常年拔毛”、“种鹅体产期拔毛”、“种鹅育成期投毛”及“肉鸽一次性拔毛”四个试验．除“成年公鹅常年拔毛”试验不设对用外，其余备试验均设对照。试验结果表明成年公鹅一年可拔毛8次，平均每只一年获得毛绒736．7克．种鹅休产期拔毛二次，平均每只获毛纺157．2克，休产期拔毛对其体重和产蛋性能并无不良影响。种鹅育成期拔毛二次，平均每只获得毛绒111．3克，对有成期生长发育未见不良影响。肉鹅一次性拔毛虽然每只可获得毛绒50．9克，但拔毛后要饲养25天以上方好出售，结果毛绒收入不延长饲养期支出，因此没有推广价值。
