摘 要:研究了褐煤中提取的硝基腐植酸钠对生长育肥猪生长性能、舍内有害气体含量和饲料中营养成分消化率的影响。结果表明,褐煤中提取的硝基腐植酸钠对生长育肥猪的促生长效果与抗生素相当,1%添加量效果较明显,且饲用该硝基腐植酸钠可降低猪舍内有害气体的含量。Studied the effects of nitro humic acid natrium extracted from lignite on growth performance of fattening pig, harmful gas content in shed and digestibility of feedstuff. The results indicated that the promotion effect of nitro humic acid natrium extracted from lignite on growth performance of fattening pig was equal with that of antibiotics, and the effect was better when addition amount of nitro humic acid natrium was 1%. And the harmful gas content in shed of pig could be decreased by feeding the nitro humic acid natrium.
