霉变玉米中呕吐毒素的提取及其对仔猪血液生理、生化及生长性能的影响

Effect of dietary lysine level on growth performances and serum biochemical indices of Hainan black pig

摘要: 探讨了人工提取霉变玉米中呕吐毒素（DON）的技术路线，以及其污染饲粮对断奶仔猪生长性能、血清生化指标、血常规指标的影响。试验选用10 头25 日龄，平均体重为7.70（依1.00）kg 的三元杂断奶仔猪，随机分为2组，分别进行对照处理（基础饲粮）和DON 处理（基础饲粮垣DON），试验期为38 d。结果表明，2 mg/kg 低剂量的DON污染饲粮造成断奶仔猪生长性能下降，使部分血清生化指标、血液常规指标产生变化，但大部分指标不发生明显变化，且对脏器指数没有影响。

Abstract: The experiment was conducted to study the effects of different dietary lysine level (0.6%, 0.8%, 1.0%) on growth performances and serum biochemical indices in Hainan black pig. The results showed that the dietary lysine had significant effect on average daily gain of Hainan black pig, and when the level of lysine was 1.0% , the growth performances were the best. The dietary lysine level had significant influence on serum albumin, but had no significant influence on content of total protein, globulin, urea nitrogen and albumin/globulin in serum. In conclusion, Hainan black pig爷s optimal dietary lysine level was 1.0.
