| dc.description.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. | en_US |
