摘 要：为了解益生素制剂在生猪养殖过程中对猪群减排、猪舍减臭和猪群生长性能的影响。采用在饲料中添加益生素、猪粪表面喷洒除臭粉和猪舍中喷洒除臭液体的“三维”立体应用方法，通过监测试验组、对照组猪群中粪便相关指标、猪舍氨气浓度和猪群生长性能情况，结果表明：试验组中猪群粪便的氮、磷、钾含量分别从11.26 mg·g-1、0.58%、3000 mg·g-1下降到10.22 mg·g-1、0.34%、2100 mg·g-1;猪舍环境中的氨气浓度从（3±0.026）mg·m-3下降到（2±0.023）mg·m-3;臭气情况有效缓解，猪舍臭气等级从明显（++）下降为轻微（+）;猪群生长性能提高，日增重从289.63 g·d-1提高到318.79 g·d-1，死淘率下降0.2%。試验结果表明益生素制剂在生猪养殖中减排、除臭及提升生长性能等方面取得较好效果。

Abstract： In order to investigate the effects of the preparations of probiotic on the emission reduction， odor reduction of pigsty and growth performance of pigs during the process of pig breeding， the ″three-dimensional″ application method of adding probiotics in the feed， spraying deodorant powder on the surface of pig manure and spraying deodorant liquid in the piggery was used to monitor the relevant indicators of feces， the ammonia concentration in piggery and the growth performance of pigs in the experimental group and the control group. The results showed that： in the experimental group， the contents of nitrogen， phosphorus and potassium in the feces of pigs decreased from 11.26 mg·g-1， 0.58% and 3000 mg·g-1 to 10.22 mg·g-1， 0.34% and 2100 mg·g-1， respectively. The ammonia concentration in the environment of piggery decreased from （3±0.026） mg·m-3 to （2±0.023） mg·m-3. The odor situation was effectively alleviated， and the odor level in piggery decreased from obvious （++） to slight （+）. The growth performance of pigs was improved， and the daily gain increased from 289.63 g·d-1 to 318.79 g·d-1， and the mortality rate decreased by 0.2%. The results showed that the preparations of probiotic had good effects on the emission reduction， deodorization and growth performance of pigs during the process of pig breeding.

我国是一个生猪养殖大国，据国家统计局数据，2020年末全国生猪存栏40650万头，全国猪肉产量4113.3万t，人均猪肉占有量29.2 kg，猪肉已经成为人们生活“菜篮子”工程的重要组成部分。近年来，我国生猪养殖模式已经从家庭养殖逐步发展到规模养殖，2020年全国生猪养殖规模化比重达到57.1%，规模化程度和产业集中度显著提升。随着养殖规模化、工厂化持续发展，资源化利用不断推进，粪尿得到较为科学的处理与应用，实现了资源循环利用，变废为宝，而规模猪场也开始面临著一系列的新问题，其中猪场空气污染问题已经成为制约了养猪业健康发展新的突出问题。因此，如何减少猪场异味对周边环境、居民的影响，给新时代养殖场保护周围生态环境提出更高的要求，这些都成为我国畜牧业需要解决的迫切问题。……
