Description
Summary:The inclusion of prebiotics and/or probiotics in broiler diets as a substitute for antibiotics is a topic of interest in poultry nutrition research due to concerns about antibiotic resistance and the need for sustainable poultry production practices. A total of 200 one-day-old chicks were housed in 40 cages, with eight cages repeated per treatment. Birds were fed a basal diet supplemented with one of five feed treatments at the following rates: 0 (control), 0.05 g Neoxyval/kg (antimicrobial growth promoter (AGP)), 0.2 g GalliPro®/kg (probiotic), 0.6 g TechnoMos®/kg (prebiotic) and a mixture of 0.2 g GalliPro®/kg + 0.6 g TechnoMos®/kg (symbiotic). During 0–42 days, the growth performance of broilers, carcass characteristics and intestinal histomorphology were investigated. The AGP, prebiotic and probiotic-treated birds outperformed the control and symbiotic-treated groups in terms of body weight gain, feed conversion, performance index and feed efficiency. The birds given AGP and probiotics had the longest partial and total small intestine length, while the birds given prebiotics had the smallest. In addition, prebiotic-treated birds had longer ileum villi and higher ileal lactic acid bacteria colonies than control and AGP-treated birds. Clostridium perfringens was eradicated from the ileum by probiotics, but not from the caecum. In conclusion, probiotics and prebiotics can be used as an alternative to antibiotics in broiler diets.
