中链甘油三酯在动物体内的代谢及应用研究

Metabolism in animal body and application of medium-chain triglycerides

中链甘油三酯(MCT)是由6～12个碳原子的脂肪酸组成的甘油三酯,它们在体内具有消化、吸收、转运、代谢快的特点。MCT能迅速提供能量,但同时也产生大量的酮体,进入血液,使血液中酮体水平升高。MCT用于仔猪的饲养效果不一致,但用于母猪和鸡的饲养中有明显的正效果。如何消除MCT在肝细胞内氧化产生的大量酮体带来的不利影响,以及寻找一种简便的饲喂方法,都有待今后进一步的研究。

Medium-chain triglycerides (MCT) have fatty acids 6 to 12 carbon atoms long. In animal body the digestion, absorption, transport and metabolism process of MCT are more rapid relative to long-chain triglycerides (LCT). MCT can release rapidly energy to animal and may also increase the blood concentration of ketone. Perhaps orally dosed MCT do not improve the performance of piglets, but they can improve the performances of sow and chicken. These problems, how to eliminate negative effects of ketone in hepatocell and how to find a simple feeding way, need be investigated.
