Abstract

This experiment was carried out to investigate the effect of dietary supplementation of complex probiotics and enzyme on air quality in finishing pig building and the performance of finishing pigs. A total 117 crossbred $[(Landrace{\times}Yorkshire){\times}Duroc]$ pigs were randomly arranged into nine groups and assigned to three treatments. Pigs were fed a basal diet supplemented with 0, 0.1% level of probiotics and 0.1% level of complex probiotics and enzyme until the market weight for 42 days of the experimental period. Ammonia and hydrogen sulfide concentrations in the finishing pig building were significantly (p<0.05) decreased by dietary supplementation of complex probiotics and enzyme compared with those of control, however, indoor carbon dioxide concentration was not affected by dietary supplementation of probiotics or complex probiotics and enzyme. Average daily feed intake and feed conversion ratio were significantly improved (p<0.05) with dietary supplementation of 0.1% complex probiotics and enzyme; however, average daily gain was not affected by dietary supplementation of probiotics or complex probiotics and enzyme. In conclusion, the results obtained from this experiment suggest that the dietary supplementation of complex probiotics and enzyme for finishing pigs may improve air quality in the finishing pig building and the performance.
