选取70日龄四川白鹅、百子鹅为试验对象,以豁眼鹅为对照,比较了各品种间生产性能差异.结果表明,3个鹅种母鹅体重差异显著(P<0.05),百子鹅>四川白鹅>豁眼鹅;百子鹅在体斜长、胫围、潜水长3个体尺指标上高于豁眼鹅和四川白鹅,其中,百子鹅的胫围和潜水长明显高于豁眼鹅,差异极显著(P<0.01).3个鹅种公鹅潜水长,百子鹅>四川白鹅>豁眼鹅,差异极显著(P<0.01),百子鹅公鹅的胫长高于四川白鹅,差异极显著(P<0.01),胫围高于豁眼鹅和四川白鹅,差异极显著(P<0.01).3个鹅种各项屠宰指标间均存在着不同差异,百子鹅母鹅全净膛率、半净膛率、胸肌率显著高于豁眼鹅(P<0.05),四川白鹅腿肌率8.79%,高于豁眼鹅,差异极显著(P<0.01).百子鹅公鹅的全净膛率和胸肌率高于其他两个品种的公鹅,差异显著(P<0.05).豁眼鹅公鹅的腹脂率低于其他两个品种,差异显著(P<0.05).%The purpose of this study was to comparative analysis of productive performance in Huoyan goose,Sichuan white goose, Baizi goose at the age of 70 days. The results showed that there were differences between three female breeds in average body weight(P<0.05), which means female Baizi goose>female Sichuan White goose>female Huoyan goose. Body slope length,shank girth and diving depth of Baizi goose were better than other two breeds, especially, shank girth and diving depth of Baizi goose were higher than Huoyan goose(P<0.01). Diving depth of male Baizi goose was highest in three breeds, to be specific, male Baizi goose>male Sichuan White goose> male Huoyan goose (P<0.01), and shank length of male Baizi goose was longer than Sichuan White goose (P<0.01), as well as, shank girth of male Baizi goose was bigger than other two breeds (P<0.01). There were differences between each breeds in the slaughter traits, in which eviscerated weights, semi-eviscerated weights and leg muscle rate of female Baizi goose are better than Huoyan goose (P<0.05), and leg muscle rate of Sichuan White goose higher than Huoyan goose(P<0.01), which is 8.79%. Eviscerated weights and chest muscle rate of male Baizi goose were higher than other breeds(P<0.05). Abdominal fat rate of Huoyan goose was lower than other breeds(P<0.05).
