摘要
通过饲喂复合乳酸杆菌、喷淋除臭型复合益生菌和导入除臭型复合益生菌的组合干预方式,研究复合益生菌对猪场粪污臭气的生物降解效果。试验以2910头肉猪(平均体重约65 kg/头)为试验对象,分为对照组(918头,不进行任何干预)、Ⅰ组(1003头,饲喂剂量为2×10^(9) cfu/d的复合乳酸杆菌:植物乳杆菌、副干酪乳杆菌、鼠李糖乳杆菌,并在猪舍喷淋除臭型复合益生菌:枯草芽孢杆菌、屎肠球菌、酿酒酵母)和Ⅱ组(989头,饲喂复合乳酸杆菌+喷淋除臭型复合益生菌+粪污池内导入除臭型复合益生菌),探究猪群健康度和猪舍内氨气、硫化氢的浓度变化。结果表明,Ⅰ组猪群的平均腹泻率、发病率和死亡率较对照组分别降低了87.07%、74.44%和69.49%,Ⅱ组猪群的平均腹泻率、发病率和死亡率较对照组分别降低了73.38%、58.17%和79.38%。Ⅰ组猪舍内氨气、硫化氢的平均浓度分别降低了16.13%和15.38%,Ⅱ组猪舍内氨气、硫化氢的平均浓度与对照组相比分别降低了26.27%和26.92%。综上,通过饲喂复合乳酸杆菌、喷淋和导入除臭型复合益生菌的组合干预方式,可提高猪群健康度和降低猪舍内氨气、硫化氢的排放。
Through the combined intervention of feeding compound lactobacillus,spray deodorizing compound probiotics and introducing deodorant compound probiotics,the biodegradation effect of compound probiotics on manure odor in pig farms was studied.A total of 2910 pigs(with an average weight of about 65 kg/pig)were involved and divided into control group(918 pigs without any intervention),experimental group 1(1003 pigs,fed with 2×10^(9) cfu/d compound lactobacillus including Lactobacillus plantarum,Lactobacillus paracasei and Lactobacillus rhamnosus,and spraying deodorant compound probiotics including Bacillus subtilis,Enterococcus faecalis,Saccharomyces cerevisiae)and experimental group 2(989 pigs,fed with compound lactobacillus,spraying deodorant compound probiotics and introducing deodorant compound probiotics into the septic tank).The health status of pigs and the changes in the concentration of ammonia and hydrogen sulfide were explored.The results showed that compared with the control group,the average diarrhea rate,morbidity and mortality of pigs in experimental group 1 decreased by 87.07%,74.44% and 69.49%,and that of pigs in experimental group 2 decreased by 73.38%,58.17%and 79.38%,respectively.The average concentrations of ammonia and hydrogen sulfide in the pigsty of experimental group 1 decreased by 16.13% and 15.38% respectively,while those in experimental group 2 decreased by 26.27% and 26.92% respectively.In summary,the combination intervention method of feeding compound lactobacillus,spray deodorizing compound probiotics and introducing deodorizing compound probiotics effectively improved the health status of pigs and reduced the emissions of ammonia and hydrogen sulfide in piggery.
