Feed additives play an important role in the production performance and physiological functions of poultry. The most commonly used additives in poultry farming are microecological preparations, enzyme preparations, oligosaccharides, bioactive peptides and Chinese herbal medicine feed additives. Automatic poultry systems in Nigeria.

Microecological preparations can improve the flora of chickens, reduce the incidence of Salmonella and coccidiosis, and have a good effect on the disease resistance and immunity of chickens. Microecological preparations can feed the chicks to the serum and intestines.
