| Abstract | ||
| The present study was conducted in a private farm in Ashmoon, Menoufia Governorate, Egypt, throughout the experimental period from August to September 2023 to study the effect of dietary supplementation of different levels of yeast (Saccharomyces cerevisiae) on growth performance, some blood, antioxidant status, immunological parameters, carcass characteristics, cecal microbiota counts, some histomorphological measurements and economic efficiency of broiler under experimental conditions. A total number of 120 unsexed, one-day-old Ross 308 broiler chicks were randomly distributed and divided equally into four dietary treatment groups, with an average body weight of 40 g / chick. Each group was represented by birds in three replicates of 10 chicks each, and they were kept under similar management conditions. Broiler chicks were fed dietary treatments as follows: T1, basal diet without supplementation (control); T2, T3, and T4, fed a basal diet with 0.05, 0.10, and 0.15 g yeast/kg diet, respectively, during 1-42 days of age. | ||
