【摘要】：目的:通过测定皖东黄牛不同部位肌纤维直径的大小,探讨股二头肌、臂三头肌和腰大肌肌纤维直径的相关性。方法:将成年皖东黄牛屠宰后,对股二头肌、臂三头肌和腰大肌进行肌纤维直径测定,分析肌纤维直径的差异性和相关性,并建立三者间的回归方程。结果:股二头肌肌纤维直径为23.1667μm、臂三头肌肌纤维直径为24.7967μm、腰大肌的肌纤维直径为25.5367μm,三者肌纤维直径无显著差异性。结论:建立的最优回归方程分别为:股二头肌肌纤维直径(Y)与腰大肌肌纤维直径(X)的指数式回归方程y=14.115e0.0298x拟合效果最好,R2=0.9782。臂三头肌肌纤维直径(Y)与腰大肌肌肌纤维直径(X)的多项式回归y=-0.0035x2+0.9273x+11.513拟合效果最好,R2=0.9865。
[Abstract]:Objective: to study the correlation between biceps femoris muscle, triceps arm muscle and psoas major muscle by measuring the diameter of muscle fiber in different parts of Wandong Yellow cattle. Methods: after slaughtering adult Wandong cattle, the biceps femoris muscle was obtained. The muscle fiber diameters of triceps arm muscle and psoas major muscle were measured, the difference and correlation of muscle fiber diameters were analyzed, and the regression equations were established. Results: the diameter of biceps femoris muscle fiber was 23.1667 渭 m. The diameter of triceps arm muscle fiber was 24.7967 渭 m, and that of psoas major muscle was 25.5367 渭 m. Conclusion: the optimal regression equations are: the diameter of biceps femoris muscle fiber (Y) and the diameter of psoas major muscle fiber (X). The best fitting effect is obtained by using the exponential regression equation YJY 14.115e0.0298x. R2n 0.9782.The diameter of triceps brachii muscle fiber and the diameter of muscle fiber of psoas major muscle. The best fitting effect was obtained by the polynomial regression of YJ 0.0035 x 2 0.9273x 11.513. R2 + 0.9865.
