- Abstract
The aim of this study was to analyze the influence of the rearing system (collective, individual hutch, and tropical) on the temperament of crossbred dairy calves. Forty crossbred dairy calves were studied, distributed into three groups: 14 calves in the individual hutch system, 12 calves in the collective system, and 14 calves in the tropical system. The animals were subjected to evaluations of physiological parameters such as heart and respiratory rates, as well as a temperament test using a scale. The analyses were performed using the statistical software R. No significant differences were observed for the physiological variables among the different rearing systems. However, for the temperament test, the most reactive animals were found in the collective system. It was concluded that the temperament of crossbred dairy calves was influenced by the rearing system, with animals in the individual hutch and tropical systems showing a more docile behavior.
