PROBIÓTICOS EM RAÇÕES PARA POEDEIRAS

Abstract

The rapid and proper development of birds is strictly linked to the nutrition they receive, making it necessary to adopt criteria to maintain a high level of production. The objective of this study was to review the literature results on the use of probiotics as replacements for antimicrobials as performance enhancers, where searches for articles on google were made using the terms "probiotic in laying hens eggs quality" and "probiotic in laying hens diets". The Brazilian poultry production is constantly evolving, following the world's population growth, with an increasingly demanding and judicious public, it is necessary to use managements that ensure animal welfare, whether in terms of ambience or nutrition. A large number of additives have been studied with the objective of improving the zootechnical performance of animals. With the prohibition of antimicrobials used for this purpose, substitutes for these drugs have been sought. The probiotics are quite quoted to occupy this position, which are composed of live microorganisms, with the ability to install themselves in the gastrointestinal tract of birds, promoting improvement in their performance. The results found in the literature indicate that probiotics are an efficient substitute for antimicrobials in the feeding of laying hens.
