摘要
以70日龄太湖鹅为试验素材,测定其屠宰性能和相关肉品质指标。结果表明:①全净膛率公母鹅分别为69.01%和70.31%,差异显著(P<0.05);半净膛率公母鹅分别为77.46%和79.17%,差异显著(P<0.05);胸肌率公母鹅之间差异显著(P<0.05)。②无论公鹅还是母鹅,腿肌肉色、pH显著高于胸肌;剪切力范围在2.45～3.91kg,胸肌剪切力极显著高于腿肌(P<0.01);系水力为71.30%～73.05%。③水分含量为75.88%～76.70%,粗蛋白质含量为20.33%～20.91%,各指标间差异均不显著;粗脂肪含量为1.18%～1.45%,母鹅胸肌含量为1.45%,公鹅为1.18%,两者之间差异显著(P<0.05)。
The slaughter capability and meat quality of Taihu goose at age of 70 days were measured. The results were as follows：①there was a significant differenee between the percentage of eviscerated yield of female goose（70. 31%） and male goose（69.01% ）（P〈0.05） ; there was a significant difference between the percentage of semi- eviscerated yield of female goose （79.17 % ） and male goose（77.46 %） （P〈0.05） ; the difference of breast muscle ratio between female and male goose was significant（P〈0.05）. ②whether the goose is female or male, the flesh color and pH of leg muscle was much higher than breast muscle; The Shear force was 2. 45-3.91 kg, and the breast muscle was higher than leg muscle（P〈0. 01）; the water holding capacities was 71.30%-73. 05%. ③The percentage of moisture content and the crude protein were 75.88% -76.70% and 20.33% -20.91%, respectively, there was no significant difference between male and female or breast and leg muscle. The percentage of etude fat was 1. 18%- 1.45%, there was a signifieant difference between the breast muscle of female goose （1.45%） and male goose（1.18%）（P〈0.05）.
