THE SYSTEM OF FREE FORAGING IN HENS (Gallus gallus): AN ALTERNATIVE FOR ANIMAL WELFARE

Abstract

Current poultry production systems keep animals under constant pressure and stress. In order to reduce these stress conditions, the concept of animal welfare is now becoming more important, in which poultry can develop in a manner more in keeping with their natural behavior. That is why the models of management and care of animal health have been redesigned. In this note, the advantages of the free-run system that lead to the welfare of poultry are explained. In this system, for example, chickens develop their natural activities more frequently and tend to carry out their usual activities more completely, including greater movements of wings and flights, which is beneficial because it maintains a more resistant bone system, and there is reduction of aggressions. The disadvantages associated with this system are high mortality due to predators, as well as greater exposure to diseases and parasites.
