南非肉用美利奴羊与东北细毛羊杂交效果分析
Crossbreeding Effect of South Africa Merino and Northeast Fine-wool Sheep
摘要
Abstract
The Northeast Fine-wool sheep is a main sheep breed in northeast farming-pastoral-zone,which was bred for wool and meat in the 1960s.However,the meat performance of this breed is not obvious.Therefore,to investigate the crossbreeding effect of South Africa Merino and Northeast Fine-wool sheep,South Africa Merino was used as male parent and Northeast Fine-wool sheep as female parent to obtain the F1 generation (SN),then compared the growth and development index and wool performance of the F1 generation (SN) with Northeast Fine-wool sheep at the same age.The result showed that the weight of 3 month-old,6 month-old,and 1 year-old,and the lactation daily gain of SN were very significantly higher than Northeast Fine-wool sheep(P＜0.01);the coat of SN was still homogeneous fine wool,although the wool length and wool yield were lower,the wool fiber diameter was greater than Northeast Fine-wool sheep and the weight after shearing of SN was significantly higher than the Northeast Fine-wool sheep.The hybrid combinations of South African Mutton Merino and Northeast Fine-wool sheep can be widely used in northeast farming-pastoral-zone.关键词
