| 摘 要： | 为了研究皖南花猪部分屠宰性状的发育性变化及性别差异,试验采用0,30,45,90,180日龄的皖南花猪公、母各5头进行屠宰测定。结果表明:皖南花猪的各项屠宰指标都有不同程度的发育性变化,30日龄时,肾脏重有显著增长(P0.05),其他指标都有极显著增长(P0.01);在30～45日龄阶段,胴体斜长、膘厚、皮厚、肺脏重有显著增长(P0.05),但眼肌面积、心脏重、肝脏重、脾脏重、肾脏重增长不显著(P0.05);在45～180日龄阶段,所有指标都呈现快速的增长。出生和180日龄时,屠宰指标的性别差异均不显著(P0.05);30日龄时母猪的膘厚显著大于公猪(P0.05);45日龄时,母猪的胴体斜长和肝脏、脾脏、肾脏重显著小于公猪(P0.05);90日龄时母猪的胴体斜长显著大于公猪(P0.05);皖南花猪的肌内脂肪含量较高,且在背最长肌和半腱肌有不同的发育规律。

| Abstract: | Five Wannanhua boars and five Wannanhua gilts were slaughtered at birth,30,45,90,180 days of age respectively,and the developmental patterns and sexual dimorphism of partial slaughter performance were assayed.The results showed that the slaughter index were changed with age.All slaughter index were increased from day 0 to day 30 and from day 45 to day 180(P<0.05 or P<0.01).Body length,6,7-rib fat depth,6,7-rib skin depth,lung weight,but not loin eye areas,heart weight,liver weight,spleen weight and kidney w... |
