Avaliação do ambiente em pesquisas sobre o comportamento dos suínos em crescimento e terminação

Abstract

Pig farming can be improved in animal welfare through adaptations from behavioral analysis, but this is somewhat complex because it results from the interaction of pigs with the environment variables. The objective of this work was to analyze the environment factor in behavioral assessment surveys of growing and finishing pigs. The work was developed through a systematic review based on articles that evaluated the behavior of pigs through ethograms in the growth and finishing phases. The data were extracted and tabulated in an electronic spreadsheet to enable the evaluation and interpretation of data between experiments. The articles described different parameters of the environment and, in most cases, in a simplified way. The environment, climate, temperature, structures, management, stocking, feeders and drinking fountains, directly influence the behavior of pigs. All of these factors contribute to animal behavior both positively, calm animals with behavior characteristic of the species, and negatively, aggressive and fighting behaviors. The articles on behavioral assessment of growing and finishing pigs lack information on environmental factors, which makes it impossible to analyze the influence of the environment on the behavior of pigs.
