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

Extracting deoxynivalenol from the contaminated corn and effects of contaminated feed on the growth performance,blood routine and serum biochemical indexes of piglets

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(±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+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。

This experiment was conducted to investigate the technique of extracting deoxynivalenol from the contaminated corn and effects of contaminated feed on the changes of the growth performance, blood routine, serum biochemical indexes. A total of 10 crossbred weaner piglets with an average body weight of 7.70（±1.00） kg were randomly assigned to 2 groups as follows： control group fed with basal diet, DON group fed with basal diet ＋ DON. The experiment lasted for 38 d. The results showed that, low dose of DON （2 mg/kg） in eontaminated feed could reduce growth perfornlance of weaner piglets, and induce some changes in part of serum biochemical and blood routine indexes, but had no obvious effect on most of indicators, and had no influence on the viscera index.
