微生物发酵饲料对生猪规模化饲养生产性能和经济效益影响的研究

选用日龄相近、体况一致的杜长大三元杂交小猪,对照组289头和试验组265头。试验组日粮中添加了4%的微生物发酵饲料。试验结果表明,在90d的规模化饲养试验中,试验组生产性能和经济效益要明显优于对照组,其成活率由96.2%上升到97.7%,平均日增重提高7.0%,料肉比减少0.35%,采食量明显增加,每头猪的出栏利润由443元提高到了503元,增加了13%。饲用微生物发酵饲料,对生猪的生产性能和经济效益有明显的促进作用。

In this paper, Duroc-lanndrae--Yorkshire crossbred piggy of born at the same birth and similar body weight were randomly divided into control group （289 pigs） and experimental group （265 pigs）. In the basal diet of experimental group, 4% microbial fermentation feeds were added. The results indicated that compared to control group, in the scale feeding trial of 90d, the production performance and economic benefits of experimental group were better, its survival rate increased from 96.2% to 97.7%, the average daily gain raised 7.0%, the feed conversion ratio reduced 0.35%, and the feed intake increased significantly. In addition, each pig slaughter profit increased from 443 yuan to 503 yuan, an increase of 13%. Thus, the microbial fermentation feed had obvious promoting effect on production performance and economic performance in pig.
