Effect of Bacillus subtilis and Bacillus licheniformis inclusion in turkey diets on growth performance.The aim of this study was to evaluate the influence of a probiotic preparation containing spores of Bacillus subtilis and Bacillus licheniformis, added to feed, on growth performance of female turkeys reared until 84 days of age. A total of 300 day-old Hybrid Converter female turkeys were randomly assigned to 20 pens. The pens were randomly divided into two treatment groups: T1, received basal diets, and T2 received the same diets as group T1 supplemented with the probiotic (1.28 x 106 CFU/g). It can be concluded that the probiotic feed additive had a beneficial influence on growth performance and significantly increased the final body weights and average daily gains of female turkeys.
