性别和屠宰年龄对笼养野鸡胸肌质量的影响
The effect of sex and slaughter age on the quality of the breast muscle (Pectoralis major) in pheasants housed in aviaries.
摘要(中文译文)
本研究旨在比较在农场笼养并于21、23和25周龄屠宰的雌性和雄性雉鸡（Phasianus colchicus）胸肌（胸大肌，PM）的常规营养成分、脂肪酸和氨基酸组成以及理化特性（每个年龄组10只雌性——母鸡和10只雄性——公鸡）。性别和屠宰年龄均对PM肌品质有显著影响。然而，年龄对所分析品质指标的影响数量更多。雌性雉鸡PM肌的胶原蛋白含量较低（P ≤ 0.05），单不饱和脂肪酸（MUFA）、维生素A和必需氨基酸（EAA）浓度较高（P ≤ 0.05）。以下参数的数值随年龄增长而升高（P ≤ 0.05）：β-生育酚含量、脂肪含量、MUFA比例、MUFA/SFA比值以及肌内脂肪（IMF）的营养品质指标。UFA/SFA和DFA/OFA比值也呈升高趋势，而饱和脂肪酸（SFA）和胱氨酸浓度随年龄增长呈降低趋势（P ≤ 0.05）。本研究结果表明，尽管所比较的雉鸡组之间存在上述差异，21~25周龄屠宰的鸡肉品质优良（脂肪含量低、蛋白质含量高、EAA浓度高、脂肪酸比例理想），可作为其他类型禽肉的一种可行替代品。
Abstract
The aim of the present study was to compare the proximate composition, fatty acid and amino acid profiles, and physicochemical properties of the breast (Pectoralis major, PM) muscle in female and male pheasants (Phasianus colchicus) raised in aviaries on a farm and slaughtered at 21, 23, and 25 weeks of age (10 females - hens and 10 males - roosters per age group). Both sex and slaughter age had a significant effect on the quality of the PM muscle. However, age influenced a higher number of the analyzed quality attributes. The PM muscle of female pheasants had lower (P ≤ 0.05) collagen content and higher (P ≤ 0.05) concentrations of MUFAs, vitamin A, and essential amino acids (EAAs). The values of the following parameters increased (P ≤ 0.05) with age: β-tocopherol content, fat content, the proportion of MUFAs, the MUFA/SFA ratio, and the nutritional quality indicators of intramuscular fat (IMF). The UFA/SFA and DFA/OFA ratios also tended to increase, whereas the concentrations of SFAs and cystine tended to decrease (P ≤ 0.05) with age. The results of this study indicate that, irrespective of the observed differences between the compared groups of pheasants, the meat of birds slaughtered at 21-25 weeks of age was characterized by high quality (low fat content and high protein content, high concentrations of EAAs, a favorable fatty acid ratio) and could be a viable alternative to other types of poultry meat.
