【摘要】：為評估四川白鵝與百子鵝在遼寧地區(qū)生產(chǎn)性能的適應性,以360只70日齡豁眼鵝、四川白鵝和百子鵝為試驗素材,比較3個品種生產(chǎn)性能差異。結(jié)果表明:3個鵝種母鵝體重差異顯著(P0.05),百子鵝四川白鵝豁眼鵝;百子鵝在體斜長、脛圍、潛水長高于豁眼鵝和四川白鵝,其中,百子鵝的脛圍和潛水長極顯著高于豁眼鵝(P0.01);公鵝潛水長比較為百子鵝四川白鵝豁眼鵝(P0.01),百子鵝公鵝的脛長極顯著高于四川白鵝(P0.01),脛圍極顯著高于豁眼鵝和四川白鵝(P0.01);3個鵝種各項屠宰指標間均存在著不同差異,百子鵝母鵝全凈膛率、半凈膛率、胸肌率顯著高于豁眼鵝(P0.05),四川白鵝腿肌率8.79%,極顯著高于豁眼鵝(P0.01);百子鵝公鵝的全凈膛率和胸肌率顯著高于其他2個品種的公鵝(P0.05);豁眼鵝公鵝的腹脂率顯著低于其他2個品種(P0.05);百子鵝早期生長較快,活重最大為3 230.21 g,屠體重為2 810.97 g,依次為和四川白鵝和豁眼鵝,豁眼鵝屠宰性能好于四川白鵝。不同品種鵝體尺、屠宰性能各指標間有不同程度的相關性。
[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.
