BOVINE HEALTH INDICATORS IN DUAL-PURPOSE PRODUCTION UNITS IN THE DRY TROPICS

Abstract

Background: Beef ranks third in consumption in the Mexican market, where the diversity in supply sources and management systems used in production units is notable. This diversity is reflected in the health and welfare conditions of cattle. Objective: To evaluate health indicators of dual-purpose cattle in Michoacán, Mexico, aiming to promote quality in the meat industry. Methodology: Data were collected using the protocol adapted from UC Davis Cow-Calf Health and Handling. Bivariate and multivariate statistical techniques (principal component analysis and cluster analysis) were applied to analyze the data. Results: Six factors explain the cattle's current and past health conditions. From these, three groups of cattle were obtained with statistically significant differences in eight key indicators. Group 1 (G1) was characterized by good body condition and favorable past health status. Group 2 (G2) showed recent health problems, skin lesions, wildlife attacks, and parasitosis. Group 3 (G3) presented moderate conditions regarding past and recent health. Implications: This study provides a foundation for designing tools to enhance livestock living conditions by identifying and addressing individuals with poor health and welfare. These actions benefit livestock and directly improve the quality of meat derived from them. Conclusions: Group 2 (G2) was identified as having the greatest health problems, while G3 showed intermediate conditions and G1 grouped cattle with better health indicators. These findings underscore the importance of implementing improved animal health and welfare practices in production units to enhance the quality of meat produced.
