Beef poultry production and technologies for nutrition, immunology and genetic improvement: a narrative review

Abstract

Objective: To describe the development of the broiler industry with regard to the technological improvement implemented for nutrition, immunology and genetic improvement. Bibliographic review: The technological increment used for the production of broilers reinforces the importance of immunomodulation, using nutrition as a quick and effective response to improve the immune system of birds, especially in their early stages of life. In this sense, there is direct interference in production, as the better the immune system, the better the development of these animals. Studies on diets with adequate vitamins, minerals, amino acids and fatty acids are recommended to improve productivity, in line with the well-being and immune capacity of birds, stimulating resistance to disease and eliminating other problems, as changes in the immune system demand energy and various nutrients for the formation of the avian defense system. Final considerations: Immunonutrition is a way to optimize the animals' immune system, by providing the necessary nutrients and in adequate amounts, for the good productive and reproductive performance of the birds.
