AMBIÊNCIA NA PRODUÇÃO DE FRANGOS: REVISÃO DE LITERATURA

Abstract

Literature review on the environment in broiler farming, an economic activity of great importance in Brazil. For this, searches of academic papers, dissertations, theses, articles and websites were carried out in the Google, Google Scholar, Scielo, Pubvet, Capes and ResearchGate databases for the last 14 years. The environment in which birds are raised directly influences their welfare, health and productive performance. The ambient temperature is one of the main factors that influence thermal comfort, which contributes to the regulation of body temperature because they are homeothermic animals. Studies have shown that the ideal temperature for broilers varies according to age, weight, genetics and stage of reproduction. The relative humidity of the air also plays an important role, as it influences the loss of heat through evaporation. In addition, air speed, solar radiation and bird density are factors that can affect thermal comfort inside the housing. The results indicate that the combination of different environmental factors can lead to heat stress, with negative consequences for productive performance and animal welfare. Therefore, the proper management of these animals must promote healthy and productive development, being economically viable for the producer.
