Breeding Effect and Analysis of Specialized Strain Longdong Cashmere Goat
摘要
Abstract
In order to breed the high-quality and high-yield cashmere group, fineness type and length type breeding ram were introduced to crossbreeding improvement and strain breeding, aimed to cultivate Longdong cashmere specialized strain which could adapt arid and semi-arid regions natural ecological feature in Longdong area. The results showed that cashmere yields of fineness type special A for adult male and female sheep were 601.67 g and 465.76 g, body weights were 36.16 kg and 29.31 kg, fineness was 14.49μm and 14.25μm, respectively; cashmere yields of length type special A for adult male and fe- male sheep were 626.49 g and 506.37 g, body weights were 37.74 kg and 29.65 kg, fineness was 15.02/~m and 14.82/zm, re- spectively. The genetic polymorphisms of 9 microsatellite loci in Long-dong cashmere goats were studied to reveal genetic diver- sity of the population. The relating effects between markers and economic traits were analyzed in a generalized linear mode. Nine microsatellite loci had significant effect on some economic traits of Long-dong Cashmere goats; meanwhile, we also dis- covered favorable genotype and some alleles above loci had positive effect and negative effect on interrelated economic traits.关键词
