Growth, carcass characteristics, meat quality and microbial aspects of growing quail fed diets enriched with two different types of probiotics (Bacillus toyonensis and Bifidobacterium bifidum)

Abstract The present investigation aimed to explore the impact of dietary graded levels of two types of probiotic bacteria (BT and BB) on growth, carcass traits, meat quality, and bacteriology of growing Japanese quail reared under cage system. One thousand and three hundred sixty Japanese quail day-old chicks randomly divided into ten groups (eight replicates each). Birds were fed a basal diet (control, T1) and the basal diet plus 0.05, 0.075, 0.10 and 0.125% BT (T2, T3, T4 and T5, respectively), 0.10% BB (T6) and the same previous doses of BT plus 0.05% BB (T7, T8, T9 and T10, respectively). Results showed a significant (P
