摘要：本试验研究AA肉鸡体重与肌纤维直径的相关关系，通过对AA肉鸡体重和肌纤维直径相关性的研究，分析在其生长过程中体重和肌纤维直径的变化规律。选择100只AA肉鸡，在笼养的环境下，自由饮水、采食。自1-7周龄每周屠宰8只，共屠宰7次。空腹状态下每周进行体重称量，并取一定量胸肌样本在显微镜下测量其纤维直径，记录相关数据，建立体重和胸肌纤维直径间的回归方程，并筛选最佳的回归方程。体重随周龄变化的最佳回归方程为：y = 22.438x2+16.674x+36.507，R2为0.9972；肌纤维直径随周龄变化的最佳回归方程为：y =-0.3979x2+9.055x+0.7457，R2为0.9886；肌纤维直径随体重变化的最佳回归方程为：y =12.647Ln(x)-46.323，R2为0.986。试验结果表明：胸肌纤维直径随体重的增加而不断增粗。因此，以体重的大小来估测肌纤维直径粗细效果较好。

Abstract : Objective: The pilot study AA broiler weight and muscle fiber diameter of the relationship, Through the AA broiler weight and muscle fiber diameter relevance of the study, In its analysis of the growth in weight and muscle fiber diameter changes in the law. Select 100 AA broilers, Captive in the environment, Free drinking water, food intake. Since the 1-7 slaughtering eight-week-old weekly, Slaughtered a total of seven times. Fasting state weight weighing a week, And take a certain amount of breast samples under the microscope measurements of it

Abstract: This experimental study AA meat chicken body weight and the muscle fiber diameter correlational dependence, through to the AA meat chicken body weight and the muscle fiber diameter relevant research, analyzes in its growth process the body weight and the muscle fiber diameter change rule.Chooses 100 AA meat chickens, under the raising in cages environment, the free potable water, picks the food.Slaughters 8 from 1-7 week age each week, altogether slaughters 7 times.Under the empty stomach condition each week carries on the body weight weighing, and takes the ration musculus pectoralis sample to survey its textile fiber diameter under the microscope, the record correlation data, establishes the body weight and the musculus pectoralis textile fiber diameter regression equation, and screens the best regression equation.The body weight along with the week age change best regression equation is: y = 22.438x2+16.674x+36.507, R2 is 0.9972; The muscle fiber diameter alon
