摘要: 旨在研究发酵床饲养模式(fermentation bed breeding,FB)以及常规水泥地面饲养模式(conventional breeding,CB)下,猪群运动时间差异,以及由此差异造成的对猪生产性能、肌纤维形态、MSTN蛋白表达的影响。结果显示,在FB条件下,猪只运动时间占总时间比率较CB显著增加82.60%(P〈0.05);生产性能上,FB与CB饲养效果相比,平均增重与平均日增重分别提高10.50%与11.72%,差异显著(P〈0.05);FB条件下猪臀部肌纤维束变粗,且与CB相比,肌纤维直径增加4.90%(P〉0.05);免疫组织化学结果显示,内源性MSTN蛋白在CB条件下,猪臀肌中的阳性比例较高,FB条件下,猪臀肌中内源性MSTN蛋白显著减少(P〈0.05)。

Abstract: The present study was conducted to investigate the difference of swine movement time between the fermentation bed feeding model (FB) and conventional cement ground single bar feeding mode (CB) ,and to investigatethe effect of swine movement time on the swine production performance, muscle fiber morphology and MSTN protein expression.The results showed that compared with the swine of CB, the swine movement time ratio of FB was increased by 82.60% (P〈0.05), the average weight gain and average daily weight gain of FB were increased by 10.50% and 11.72% (P〈0.05), respectively, and the diameter of swine gluteal muscle fiber bundle of FB was increased by 4.90% (P〉O.05).The immunohistochemistry experiment results showed that there was a higher positive proportion of endogenous MSTN protein ingluteal muscle protein of CB swine and the expression of endogenous MSTN protein in gluteal muscle protein of FB swine was significantly reduced (P〈0.05).
