摘　　要：研究不同剂量的外源色氨酸、果聚糖和酪蛋白对不同猪粪发酵液产硫化氢的影响。试验组日粮中添加纳豆芽孢杆菌,对照组不添加。猪粪液全部体外厌氧发酵。结果表明:试验组猪粪乳酸杆菌和梭菌含量分别高于(P<0.01)和低于(P<0.05)对照组,发酵液硫化氢含量低于对照组(P<0.05);果聚糖对两组猪粪发酵液产硫化氢影响最大,色氨酸对两组猪粪发酵液产硫化氢影响最小。建议猪日粮中添加纳豆芽孢杆菌及调整猪粪中果聚糖含量以减少猪粪发酵液中硫化氢的产生。The effects of different dose of exogenous tryptophan, fructan and casein on hydrogen sulfide production from different manure fermentation liquid were studied in this paper. The Bacillus Natto was added into the tested group of pig manure, but not in control group. All liquid manures were anaerobic fermented in vitro. The results showed Clostridium and LactobaciUus contents in tested group were significantly higher （P 〈 0. 01 ）and lower （P 〈0.05 ）respectively than that in control group. The hydrogen sulfide content of fermenta- tion liquid in tested group was significantly lower than that in control group （ P 〈 0. 05 ）. The effects of fructan on hydrogen sulfide production of fermentation liquid were the most, while that of tryptophan were the least. In conclusion, the supplementation of Bacillus Natto in diet and the adjustment of fructan content in pig manure could reduce the hydrogen sulfide production from pig manure fermentation liquid.
