摘要: 本试验用2×2×2因子试验估计了营养,性别和年龄对肉用山羊品种南江黄羊非胴体组织的影响。营养、性别和年龄对总非胴体组织重量有显著影响。不同因子间交互作用对总非胴体组织重量影响不显著。大多数非胴体组织部分,如体外器官,胸内器官和腹腔器官极显著(P<0.001)和显著地(P<0.05)受到营养、性别和年龄因子的影响。最小二乘分析结果表明:在低营养水平下,南江黄羊公羊非胴体组织重量比母羊重。在高营养水平时,公母羊间非胴体组织总重量间的差异减小。年龄和性别对非胴体组织总量和影响始终显著。

Abstract: A 2×2×2 factorial experiment was designed to evaluate the effect of the nutrition, sex and age on non carcass organs of Nanjiang meat goat breed. The total 50 kids were measured. Nutrition, age and sex affected significantly total non carcass tissue weight. The interactions of different factors have no significant effects on it. Most of the separate weights of non carcass external organs, thoracic organs and visceral organs were affected significantly(P<0.001-0.05) by nutrition, age and sex. The results of least-squares means showed that the weight of non carcass organs was larger in male than that in female kids under lower level of nutrition. A high plane of nutrition declined the weight difference of non carcass between male and female. The effect of age on the weight of non carcass organs was marked.

Key words: NOM CARCASSORGANS, GOATS, NLTRITION, SEXUALITY, AGE
