Effects of Bacillus spp. as a supplemental probiotic in diets for weaned piglets

This article evaluated the effects of supplemental probiotic Bacillus subtilis (Bs) ATCC 6051a (1.6x109cfu/mL) in diets for weaned piglets on their performance and occurrence diarrhoea. Sixty piglets, 30 ±3 days old with initial bodyweight 8.41±0.92 kg, were allotted randomly to six pens ten piglets. There two replicates each treatment, namely a control diet (C), supplemented 1% Bs (E1), 3% (E2). Feed was provided ad libitum as flour meals per day. materials examined total numbers fungi, aerobic mesophilic bacteria (TNG), Coliforms, Escherichia coli Salmonella spp. The addition did not influence (P >0.05) (BW) or average daily weight gain (ADWG). However, across experimental period ADWG greater E2 E1 than C (>1.12 1.08 times compared C). intake (ADFI) by pigs fed E2. efficiency higher diet. Addition decreased (P<0.05) diarrhoea around 8% C, 4% Bs. A 23.4% produced soft faeces. Diarrhoea scores 2 (mild diarrhoea) 3 (severe observed 43.75% 32.81% pigs. No differences detected between treatments. results suggested that could positively affect growth mitigate
