微生态酶制剂对鸡舍空气净化的研究

为有效降低鸡舍中有害气体，于诸城外贸桃园肉鸡场随机抽取5栋健康的10日龄AA肉鸡舍（各有2000只鸡），在日粮中分别添加0、0.5、1、3、5 g/kg的酶制剂（主要成分为地衣芽孢杆菌、粪肠球菌、嗜酸乳杆菌等），利用Andersen-6级撞击式空气微生物采样器和CD-1便携式大气采样器分别搜集舍内气体，观察酶制剂对肉鸡舍内空气菌落总数和发酵粪中氨气含量的影响。试验结果表明：与对照组相比，在日粮中添加3 g/kg的酶制剂可显著降低空气中微生物含量和减少氨气的含量（P<0.05）。

Study on Purifying Atmosphere of Microbe Enzyme in Henhouse

In order to reducing badly atmosphere efficiency in henhouse, 5 henhouses were randomly allocated in Taoyuan foreign trade in Zhucheng city, each have 2000 10-day-age AA healthy henhouse. Enzyme was supplied with 0, 0.5, 1, 3, 5 g/kg respectively in broilers diet, which contains lichen sporangium, enterococcus faecalis, acid milk bacillus an so on. We collected the atmosphere in henhouse using Andersen-6 impacting airborne (FA-1,6-stage) fungal samples and CD-1 airborne samples. The result showed that, compared with the control group, the addition of 3 g/kg probiotics could remarkably decrease the air microbe quantity (P< 0.01), and it could dramatically decreased the fecal emission of ammonia ( P< 0.01) .
