Abstract Use of multi-strain probiotics in poultry nutrition provides advantages, including promoting microbial diversity the birds’ gut. Less investigated, as compared to broilers, is how application affects performance and health Japanese quails. Up date effects either based on a single microorganism or using dose probiotic were investigated. The aim study was investigate effect gradual levels applied quails’ diet their performance, carcass, microbiological immunological parameters. Total 240 quail mixed sex chicks randomly selected into four treatments: 0.15, 0.10, 0.05 g/l control group not provided with probiotic. Body weight gain (BWG), feed intake (FI), conversion ratio (FCR), carcass characteristics, gut microbiome species sheep red blood cell (SRBC) immunoglobulin IgT, IgG IgM antibodies determined. Repeated measures ANOVA performed parameters related productive birds, while one-way all other SAS software v 9.4. FI highest (16.84±2.19) did differ significantly between groups (from 16.53±2.12 15.18±1.86). FCR lowest (3.15±0.28 3.07±0.27), two birds which received (2.8±0.23 2.77±0.24, respectively). Birds had lower counts IgT (5.63±0.26 5.75±0.25, respectively) (4.00±0.38 4.13±0.3, respectively), treatment receive Lactobacillus (6.98±0.01), those amount higher E.Coli (6.67±0.01). Multi-strain overall positive health, efficacy varied depending dosage.
