【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(P0.05),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(P0.01);公鹅潜水长比较为百子鹅四川白鹅豁眼鹅(P0.01),百子鹅公鹅的胫长极显著高于四川白鹅(P0.01),胫围极显著高于豁眼鹅和四川白鹅(P0.01);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(P0.05),四川白鹅腿肌率8.79%,极显著高于豁眼鹅(P0.01);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(P0.05);豁眼鹅公鹅的腹脂率显著低于其他2个品种(P0.05);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。
[Abstract]:In order to evaluate the adaptability of Sichuan white geese and Baizi geese in Liaoning, 360 70 day-old Huoyan geese, Sichuan white geese and Baizi geese were used as experimental materials to compare the differences of production performance among the three varieties. The results showed that the body weight of the three geese was significantly different (P0.05), the body weight of the three geese was significantly higher than that of Huoyan goose and Sichuan white goose, and the body length, shank circumference and diving length of the Baizi goose were higher than those of Huoyan goose and Sichuan white goose. The shank circumference and diving length of the 100 female geese were significantly higher than that of the Huoyan goose (P0.01), the diver length of the male geese was significantly higher than that of the Sichuan white goose Huoyan goose (P0.01), the shank length of the Baizi goose male goose was significantly higher than that of the Sichuan white goose (P0.01), the tibial circumference was significantly higher than that of the Huoyan goose and Sichuan white goose (P0.01). There were different slaughtering indexes among the three geese (P0.01). 100 geese and geese, full and semi-clean, The rate of pectoral muscle was significantly higher than that of Huoyan goose (P0.05), the percentage of leg muscle of Sichuan white goose was 8.79, which was significantly higher than that of Huoyan goose (P0.01); the rate of total bore and pectoral muscle of the male goose was significantly higher than that of the other two breeds (P0.05); the abdominal fat rate of Huoyan goose was significantly lower than that of the other two geese (P0.05). Two of them (P0.05); the early growth of Baizi Goose was faster, The maximum live weight was 3 230.21 g and the slaughtering weight was 2 810.97 g, which was better than that of Sichuan White Goose and Huoyan Goose. There were different correlations between body size and slaughter performance of different breeds of geese.
