Effect of benzoic acid and combination of benzoic acid with a probiotic containing Bacillus cereus var.  Toyoi in weaned pig nutrition. 
The purpose of this study was to assess the efficacy of a probiotic containing Bacillus cereus var.  Toyoi spores (Toyocerin) and benzoic acid (VevoVitall) on growth performance and diarrhoea in weaning pigs, against negative controls.  The trial groups were as follows: (a) NC group (Negative Controls): No treatment (b) TOYO group: Same feed as in the controls plus Toyocerin at a dose of 1 x 10(9) Bacillus cereus var.  Toyoi spores/kg feed, (c) BA group: Same feed as in the controls plus VevoVitall at a dose of 5 g/kg feed (5000 ppm benzoic acid) and (d) TOYO+BA group: Same feed as in the controls plus Toyocerin at a dose of 1 x 10(9) Bacillus cereus var.  Toyoi spores and VevoVitall at a dose of 5 g/kg feed.  In conclusion, the results of this study indicated that administration of Bacillus cereus var.  Toyoi spores at 1 x 10(9)/kg feed or benzoic acid at a dose of 5000 ppm or the combination of 1 x 10(9) Bacillus cereus var.  Toyoi spores and 5000 ppm of benzoic acid/kg feed, improved the growth performance parameters and reduced the severity of diarrhoea in weaning pigs.
