Effect of Enzyme Supplementation on Broiler Chicken: A Literature Review

Abstract

While broiler chicken breeding is becoming more expensive and the market demand for chicken meat is constantly increasing, farmers are in need of a supplement that could boost their production while maintaining the animal’s welfare. When antibiotics usage as growth promoters got banned in many countries due to negative impacts on the consumer’s health, enzyme supplementation started increasing worldwide for different reasons. Several studies have been conducted on the effects of exogenous enzyme supplementation on the broiler chicken’s body, showing their impacts on different traits such as immunity, nutrition, intestinal microflora, and growth rate. This thesis demonstrates how different exogenous enzymes can have a positive impact on broiler chickens by boosting their immunological system or by reducing the pathological lesions associated with different viral or bacterial infections.
