| 摘 要： | 通过对宰后延边黄牛肉血清生化、肌纤维结构及蛋白质表达的测定,考察宰前饲喂延边黄牛复合磷酸盐水对其生理生化指标的影响。结果显示:宰前饮用0.10%的复合磷酸盐水可降低延边黄牛肉的肌纤维面积和周长,并显著降低宰后Troponin-T表达量,提高Creatine Kinase表达量,对改善宰后延边黄牛肉的血液生化指标有显著作用,可在一定程度上减少宰前应激,改善肉质。

| Abstract: | The effects of serum phosphate biochemical, muscle fiber structure and protein expression on post-mortem Yanbian yellow cattle were studied to investigate the effects of compound phosphate water on the physiological and biochemical indexes of Yanbian yellow cattle before slaughter. The results showed that drinking 0.10% of compound phosphate water before slaughter could reduce the muscle fiber area and circumference of Yanbian yellow beef, and significantly reduce the expression of Troponin-T and increase the expression of Creatine Kinase after slaughter, and improve the blood biochemical index of Yanbian yellow cattle after slaughter. Morevover, a significant effect on, reducing the pre-slaughter stress and improving meat quality were also found. |
