不同杂交组合鹅产肉性能的研究

Meat Production Performances of Geese in Different Crossbred Combination

[目的]研究不同杂交组合鹅的产肉性能,为肉鹅新配套系的培育提供参考依据。[方法]选择太湖鹅、五龙鹅、皖西白鹅、四川白鹅和三花鹅为研究对象,设计了8个杂交组合。分别对8个杂交组合90日龄鹅的体尺、屠宰性能、常规肉品质和肌肉成分进行测定和比较分析。[结果]WXSC组合除髋骨宽外其他各项体尺指标都最大,而SHSC组合的平均体重、体斜长、胸深、胸宽、胫长和颈长都最小。活体重、屠体重和腹脂重都以WXSC组合为最高,分别为3291.36、2956.46和77.84g。SHWL组合屠宰率为92.96%,高于其他7个组合的水平。剪切力值SHT最小只有3.09kg,WXWL最大3.78kg。系水力SCWL组合最高(66.46%),WXSC组合最低(61.48%)。水分含量SHWL最高(73.05%),SCT组合最低(66.77%)。蛋白含量SHT组合最高(23.32%),SHWL最低(21.94%)。脂肪含量SHT组合最高(3.06%),SCWL组合最低(1.67%)。[结论]WXSC组合生长速度最快,SHT组合产肉性能最佳。

[Objective] To study the meat production performance of goose in different crossbred combination,and provide a reference for cultivating new multiplication strains of meat geese.[Method] A total of five kinds of geese including Taihu goose,Wulong goose,Wanxi white goose,Sichuan white goose and Sanhua goose were selected as research object,and designed eight crossbred combinations.The body measurements,slaughter performance,conventional meat quality and muscle composition of 90-day-old geese in eight crossbred combinations were determined and comparatively analyzed.[Result] All the body measurement indexes except thurl width of WXSC combination were the biggest in the eight crossbred combinations.Contrarily,the body measurement indexes of SHSC combination,including the average body weight,body slope length,breast depth,breast width,shank length,neck length and half-diving depth were the least in the eight crossbred combinations.The live weight,slaughter weight and abdomen fat weight of WXSC combinations ware 3 291.36,2 956.46 and 77.84 g,which were the biggest in eight crossbred combinations.The slaughter rate of SHWL combinations was 92.96%,and more than other crossbred combinations.The Shear force of SHT and WXWL combinations were the lowest（3.09 kg） and the highest（3.78 kg）,respectively.The water holding capacities of SCWL and WXSC combinations were the highest（66.46%）and the lowest（61.48%）,respectively.The percentage of moisture content of SHWL and SCT combinations were the highest（73.05%）and the lowest（66.77%）,respectively.The crude protein content of SHT and SHWL combinations were the highest（23.32%）and the lowest（21.94%）,respectively.The percentage of crude fat content of SHT and SCWL combinations were the highest（3.06%）and the lowest（1.67%）,respectively.[Conclusion] The growth rate of WXSC combination is the fastest,and the meat performance of SHT combination is the best.
