云南剥隘鸡与河南肉鸡肌肉中肌苷酸含量的 比较研究
目的 比较研究不同月龄、性别的云南剥隘鸡与河南肉鸡肌肉中不同胴体部位的肌苷酸含量。 方法 随机选取健康5月、7月龄左右的云南剥隘鸡、河南肉鸡, 公母各10只, 屠宰取胸肌和腿肌待测。采用高效液相色谱法测定出不同月龄(5、7月龄)、性别及胴体部位(胸肌、腿肌)的云南剥隘鸡和河南肉鸡肌肉中肌苷酸含量。结果 云南剥隘鸡、河南肉鸡肌肉中肌苷酸含量分别为2.4374~3.3192 mg/g、2.2095~ 3.0220 mg/g; 5月、7月龄的云南剥隘鸡肌肉中肌苷酸含量均显著高于同月龄的河南肉鸡(P<0.05);云南剥隘鸡肌肉中肌苷酸含量高于同性别的河南肉鸡, 其中2种品种的母鸡肌肉中肌苷酸含量差距更显著(P<0.05); 云南剥隘鸡胸肌、腿肌中肌苷酸含量均显著高于相同胴体部位的河南肉鸡(P<0.05)。结论 不同月龄、性别、胴体部位对2个品种鸡肌肉中肌苷酸含量的差异性均产生显著影响, 云南剥隘鸡肌肉中肌苷酸含量要高于相同条件下的河南肉鸡。
Objective To compare the concentrations of inosinic acid of Yunnan Boaichicken and Henan broiler between different ages, genders and carcass parts. Methods Five-month-old and seven-month-old Yunnan Boaichicken and Henan broiler, including 10 males and 10 females, were chosen and slaughtered, and the chest and leg muscles were tested. The concentrations of inosinic acid of Yunnan Boaichicken and Henan broiler in different ages, genders and carcass parts were detected by high performance liquid chromatography. Results The concentrations of inosinic acid in Yunnan Boaichicken and Henan broiler were 2.4374~3.3192 mg/g and 2.2095~3.0220 mg/g, respectively. The concentrations of inosinic acid in Yunnan Boaichicken at 5-month-old and 7-month-old were significantly higher than the same month in Henan chicken (P<0.05). The concentrations of inosinic acid in Yunnan Boaichicken at different genders were higher than that of the same gender in Henan chicken and the difference of the concentrations of inosine acid between two brands of hen was more significant (P<0.05). The concentrations of inosinic acid concentration in pectoral muscle and leg muscle of Yunnan Boai chicken were significantly higher than the same carcass part of Henan chicken (P<0.05). Conclusion The inosinic acid content in 2 varieties of chicken is significantly affected by ages, genders and carcass parts, and the content of inosinic acid of Yunnan Boaichicken is higher than that of Henan broiler under the same condition.
