摘要:

通过在断奶仔猪日粮中添加中链脂肪酸混合物(MCFAs)，同时以一个成熟的中链甘油三酯(MCT)产品作为对照，研究MCFAs对断奶仔猪生长性能、血液指标、肠道形态结构以及消化道pH值的影响。共选取200头断奶仔猪，随机分为5个处理组：空白对照组(不添加)、低剂量添加组(0.2% MCFAs)、中剂量添加组(0.4% MCFAs)、高剂量添加组(0.8% MCFAs)和产品对照组(2.5% MCT)，每组4个重复，每个重复10头猪，试验为期42 d。结果表明：MCFAs对各个时期的平均日采食量(ADFI)、平均日增质量(ADG)和料肉比(F/G)影响均不显著(P>0.05)；MCFAs显著提高了断奶仔猪血清中总蛋白(TP)的含量(P<0.05)，显著降低了总胆固醇(TCH)含量(P<0.05)，高剂量添加组(0.8% MCFAs)的总甘油三酯(TG)含量显著降低(P<0.05)，中剂量添加组(0.4% MCFAs)的谷丙转氨酶(ALT)含量显著增加(P<0.05)；MCFAs显著降低断奶仔猪胃和十二指肠pH值(P<0.05)。由此可见，MCFAs对于断奶仔猪的生长性能影响不大，但会减少采食量，可以增加断奶仔猪的绒毛高度，降低消化道的pH值，并对血液生化指标产生一定的影响，从而从某些方面提高断奶仔猪的生长性能。
