内蒙古白绒山羊与河西绒山羊杂交对产绒量和绒品质的影响

河西绒山羊和内蒙古白绒山羊生存环境相同,前者产绒量低,绒品质好,后者产绒量高,绒品质相对较差。本文旨在评价内蒙古白绒山羊与河西绒山羊杂交对后代产绒量和绒品质的影响。从河西绒山羊主产地平山湖测定11只河西绒山羊、10只内蒙古白绒山羊和10只杂种产绒量,采集颈部山羊绒测定细度、含绒率和长度。测定结果表明河西绒山羊与内蒙古白绒山羊杂交后,杂种后代平均产绒量比河西绒山羊提高了23.43%。杂种后代的山羊绒平均细度比河西绒山羊粗0.32μm,比内蒙古白绒山羊细1.64μm。杂种后代山羊绒长度比河西绒山羊增加5.85mm,比内蒙古白绒山羊增加2.90 mm。

Effects of Inner Mongolia Cashmere Goats Cross Hexi Cashmere Goats on Cashmere Yield and Quality

The cashmere yield of Hexi Cashmere Goats was lower than Inner Mongolia Cashmere Goats,but the cashmere quality of Hexi Cashmere Goats was better than Inner Mongolia Cashmere Goats,although they lived in the same environment.This study aimed to evaluate the effect of Inner Mongolia Cashmere Goats cross with local Hexi Cashmere Goats on the cashmere yield and cashmere quality.Cashmere yield of 11 Hexi Cashmere goats,10 Inner Mongolia Cashmere Goats and 10 crossbreeding goats from Pingshanhu were measured,neck cashmere wool were measured for fineness,cashmere content rate and length.The results showed that average cashmere yield of crossbred offspring increased by 23.43%.Average fineness of crossbred offspring was thicker than Hexi Cashmere goats by 0.32μm,thinner than Inner Mongolia Cashmere by 1.64 μm.The length of crossbred offspring was longer than Hexi Cashmere goats by 5.85mm,longer than Inner Mongolia Cashmere by 2.90 mm.
