During the collared peccaries’ (Tayassu tajacu) management, raised in captivity at Rio Grande do Norte’s Semi-arid, is common, in the hottest hours of the day, the animals’ death after clinical manifestations of myophaty by capture. The objective of this work was to study the stress syndrome in collared peccary, submitted to capture and containment in different hours of the morning. Thirty-five collared peccaries were used and divided in seven groups with five animals, they were evaluated to each one hour, to 6 a.m up to 1 p.m, generating seven intervals (treatments). For 35 days, in week intervals, clinical, hematologic, anatomopathologic exams, and physico-chemical of the meat were realized. There was significant increase (P<0,05) in the respiratory and cardiac frequencies, beyond the rectal temperature from the first up to the seventh treatment. Spleen petechiaes and heart ecchymosis had been observed in the necroscopic exam. At the microscopic exam, it was observed degeneration, necrosis, and retraction of heart and skeletal muscle fibers. At the physico-chemical, it was observed high indexes of water besides low pH in the meat. It was concluded that capture and containment, in the hottest hours of the morning and with the management observed, cause important clinical alterations, high death frequency and physical-chemical alterations in the meat.
