Abstract

Urolithiasis is a disease characterized by the formation of calculi in the urinary tract, representing a significant health problem in beef cattle kept in feedlot systems due to its economic impacts and the compromise of animal welfare. This study describes the occurrence of a urolithiasis outbreak in feedlot cattle, aiming to report the clinical, diagnostic, and therapeutic aspects, as well as the possible predisposing factors involved. The affected animals were Nellore males, presenting clinical signs compatible with urinary obstruction, such as dysuria, anuria, abdominal distension, and apathy. Besides the nutritional management consisting of a diet with a high proportion of concentrate, the main suspicion for the outbreak was related to inadequate hygiene conditions of the water troughs and water reservoir, factors that can reduce water consumption and favor urinary concentration, contributing to the formation of uroliths. Despite the implemented procedures, five animals died as a result of uroperitoneum secondary to urinary bladder rupture associated with obstructive urolithiasis. The results highlight the importance of proper diet and water management, as well as early diagnosis and intervention, as fundamental strategies for the prevention and control of urolithiasis in intensive production systems.
