摘　　要：为研究复方营养调控剂对猪生长性能及猪舍氨气和硫化氢浓度的影响,试验选取健康、日龄相近、体重30 kg左右的杜长大三元杂种猪200头,随机分为对照组、复方营养调控剂组。试验期17 d。第1天至第3天两组均饲喂基础饲粮,从第4天起对照组饲喂基础饲粮,复方营养调控剂组饲喂在基础饲粮中添加0.2%复方营养调控剂的饲粮。结果表明,与对照组相比,饲喂14 d后,复方营养调控剂组猪舍的氨气(NH_(3))浓度下降55.88%,硫化氢(H2S)浓度下降46.47%,对仔猪生长性能无显著影响。说明在仔猪饲粮中添加0.2%的复方营养调控剂能够减少猪舍中氨气和硫化氢的排放,且不影响仔猪的生长性能。In order to study the effects of compound nutrition regulator on production performance of piglet and the concentration of ammonia and hydrogen sulfide in pig house.The compound nutritional regulator was added to the basal diet at a ratio of 0.2%and continued for 14 days.The concentration of ammonia and hydrogen sulfide in the pig house were determined every day.Finally,average daily gain and feed intake were calculated.The results showed that the compound nutritional regulator can reduce the concentration of ammonia and hydrogen sulfide significantly,and has no significant effect on production performance of piglet.
