Tóm tắt

Poultry enteric disorder causes a threat to health and contributes to the poor production performance and liveability of the poultry flocks. A large number and diversity of antimicrobials, are used in animal production for prevention and treatment of diseases, promotion of growth and improvement of productivity and production. The use of antimicrobial agents in animal husbandry linkes to the development and spread of the resistant bacteria. Probiotics, natural plant compounds, essential nutritional trace minerals are extensively assessed to replace antibiotics in feed. This experiment was carried out to evaluate the effects of three different dietary supplementation
materials on growth performance and prevention of enteric disorder in poultry. The studied results indicated that supplementing Lactobacillus acidophilus, green tea and zinc sulfate (ZnSO4) in feed for the broiler chickens improved significantly the growth performance and reduced the count of E. coli in the chicken intestines (P < 0.05) during the starter phase (chickens at 1 to 24 days old).
