摘要
为评估四川白鹅与百子鹅在辽宁地区生产性能的适应性,以360只70日龄豁眼鹅、四川白鹅和百子鹅为试验素材,比较3个品种生产性能差异。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、潜水长高于豁眼鹅和四川白鹅,其中,百子鹅的胫围和潜水长极显著高于豁眼鹅(P<0.01);公鹅潜水长比较为百子鹅>四川白鹅>豁眼鹅(P<0.01),百子鹅公鹅的胫长极显著高于四川白鹅(P<0.01),胫围极显著高于豁眼鹅和四川白鹅(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%,极显著高于豁眼鹅(P<0.01);百子鹅公鹅的全净膛率和胸肌率显著高于其他2个品种的公鹅(P<0.05);豁眼鹅公鹅的腹脂率显著低于其他2个品种(P<0.05);百子鹅早期生长较快,活重最大为3 230.21 g,屠体重为2 810.97 g,依次为和四川白鹅和豁眼鹅,豁眼鹅屠宰性能好于四川白鹅。不同品种鹅体尺、屠宰性能各指标间有不同程度的相关性。
In order to study on the adaptability of production performance of Sichuan White goose and Baizi goose in Liaoning area, body measurements and slaughter traits were measured in Huoyan goose,Sichuan white goose, Baizi goose at the age of 70 days, and correlative parameters were analyzed. There were different between goose breeds in average body slope length, chest bone length, chest width, shank length, shank girth and half-diving depth,and the body slope lengh and half-diving depth of Baizi goose were longer than those of the other two varieties. There were differences between each breeds in the slaughter traits of body weight,slaughter weight and eviscerated yield percentage,in which of those Baizi goose were better. The abdominal fat weight of Huoyan goose was 134.02 g,which was significantly lower than those of two others. The leg muscle rate of Sichuan White goose was 8.79%,which was higher than those of others, and there were no difference between three goose breeds in semi-eviscerated weights, leg muscle rate and dressing percentage. There are different degrees of correlation between of different varieties of goose in body measurements and slaughter traits.
