Bem estar animal em sistema de confinamento de bovinos de corte: um estudo de caso

Abstract

Beef cattle confinement is a widely used practice to increase production efficiency, as it allows animals to reach slaughter weight in a shorter period of time. However, the restricted environment and intensive management can affect animal welfare, leading to behavioral and productive changes. This study aimed to analyze the behavior and welfare of confined cattle at Fazenda Bergamini, located, in the municipality of Riversul, in the countryside of São Paulo State. A total of 5,206 Nelore cattle, with an average entry age between 24 and 30 months, were evaluated in six confinement rows from July 14 to 19, 2025. Observations were conducted four times a day (6a.m, 9a.m., 11a.m., and 2p.m.) through direct behavioral observation and recording of management practices. Nutritional, structural, and environmental aspects were analyzed, as well as sanitary and handling procedures. The results showed that the animals displayed appropriate behavior, remaining at the feed bunk for 40 minutes to 1 hour, with an average daily weight gain of approximately 2.0 kg/animal/day. The structural and ventilation conditions were considered satisfactory, although improvements are needed regarding the frequency of water trough cleaning, feed bunk space, and the occasional use of electric prods during loading. It is concluded that the evaluated confinement system satisfactorily meets the principles of animal welfare, presenting good productive efficiency and potential for improvement in specific management aspects.
