Análise do comportamento e vocalização de frangos de corte pela captura combinada de som e imagem aos 14 dias de criação submetidos a reduções cíclicas de temperatura.

Abstract

Animal welfare is an issue of increasing significance for the whole world consumers, that are becoming interested in animal production systems, demanding production methods that are interested in productive methods, and demanding good animal welfare practices. One of the main subjects that affect the welfare of commercial poultry production is the thermal comfort. The ways of quantify and qualify the poultry welfare degree is being changing. Some behavior answers like vocalization, animal actions or postures are associated to animal welfare. The presence of animal behavior observers affect directly in animal behavior and the interpretation of the events may be subjective. The animal precision technique of signal capture like images and sound are important alternatives to replace a human observer. The objective of this research was to study behaviors related to the animal welfare of 14th days old broilers using image and sound analysis. The automated processes of signal capture and analyze were evaluated too. It was concluded that the cyclic temperature reduction affect significantly in broilers behavior and vocalization. The software and hardware used in this research allow the automated image and sound caption and analysis.
