Effects of dietary Bacillus subtilis supplementation on the cecum microbiota of broiler chickens
In this study, we supplemented the diets with 300 and 500 mg/kg of Bacillus subtilis DSM32324 and DSM32325 (3.2*10^9 CFU/g). The effects of Bacillus subtilis on broiler growth performance, intestinal health and cecum microbiota were investigated to dig out the key microbes associated with intestinal health.
