Effect of Bacillus toyonensis BCT-7112^T supplementation on growth performance, intestinal morphology, immune-related gene expression, and gut microbiome in Barbary ducks.

ABSTRACT: This study aimed to investigate the effect of Bacillus toyonensis BCT-7112^T supplementation on growth performance, intestinal morphology, immune-related gene expression, and the cecal microbiota of meat ducks. A total of 150 one-day-old male Barbary ducks were divided into 3 groups with 5 replicates (n = 10 ducks per replicate) by completely randomized design and offered diets supplemented with the commercial product Toyocerin (containing 1 × 10⁹B. toyonensis BCT-7112^T viable spores/g product) at the levels of 0, 500, or 1,000 mg/kg (0, 500, or 1,000 ppm), respectively, for 8 wk. The results showed that although ducks in the 500 ppm B. toyonensis BCT-7112^T group displayed numerically better values (e.g., weight gain and feed conversion ratio) tha
