Bem-estar animal aplicado a matrizes pesadas: revisão de literatura

Abstract

With the increasing production and productivity of poultry meat, the need for research and investment in ways to improve the welfare of animals during all stages of the production cycle also grows. The constant increase in population demands for food produced in a more ethical way, in addition to the proven improvement in zootechnical indices in animals exposed to animal welfare tools, raises the need for measures in favor of the welfare of birds at different stages. of the production chain. Among the stages, the broiler breeders stand out, as they present longer production cycles, which allows for greater use of methods to encourage welfare and better zootechnical responses. This work aims to raise the different methods of stimulating natural behavior and consequent increase in animal welfare rates applied to heavy breeders and their impacts on the poultry production chain. Even with the evident conflicts between the maintenance of animal welfare and productivity, technological advances has been great allies in minimizing the impacts of production systems on animals and improve their life quality.
