Cattle hoof diseases have multiple causes, including infectious, genetic and environmental, high yield, stress, nutrition, race, physiological condition, and both animal and human behavior. It is gaining importance due to the production intensification. The aim of this study was to determine and compare the prevalence of hoof diseases in dairy farms and feedlots in Tandil county, Buenos Aires Province, Argentina. A total of 24 dairy farms in 2005 and a feedlot in 2013 were included in the study. Animals with claudication were separated from the rodeo and clinically examined. Crude prevalence, prevalence by pathologies and by affected members were calculated. Differences between the prevalence of each production systems by Chi square (p < 0.05) and Prevalence Ratio were estimated. The crude prevalence was 2.71% in dairy farms (12,132 animals), and 0.57% in feedlots (14,500 animals) (Prevalence Ratio = 4.73; 95% CI = 3.72% to 6.02%). The trauma prevalence was 0.17% in feedlots and 0.016% in dairy farms (p < 0.05), digital dermatitis (0.69% dairy, feedlot 0.13%; p < 0.05) and interdigital (0.81% dairy, feedlot 0.1%; p < 0.05). In both productions systems, hind limbs were the most affected (feedlot 90.4% and 88.1% dairy). Low prevalence observed in feedlot could be due to the low animal's age. Trauma was prevalent in feedlot animals while digital and interdigital dermatitis were more common in dairy farms.
