Influence of the efficacy of a probiotic complex containing Bacillus subtilis and Pichia farinosa on the growth performance and fecal microbiota of finishing pigs

摘要

A total of 120 finish pigs [(Landrace x Yorkshire) x Duroc; 52.61 +/- 2.37 kg] were randomly allotted into three treatments for a 70 d trial to evaluate the growth performance and fecal microbiota counts in finishing pigs. Treatment groups were (i) basal diet (CON), (ii) CON + 0.1% probiotic complex (TRT1), and (iii) CON + 0.2% probiotic complex (TRT2). Each treatment consisted of eight replicate pens with five pigs per pen. The average daily gain and fecal Lactobacillus counts of TRT2 were increased (P 0.05) compared with CON treatment. The result showed that 0.2% complex probiotic was more effective than 0.1%.
