Short summary
This study aims to investigate the screening of leptin genetic polymorphism and its effect on lameness prevalence. Prevalence of lameness was evaluated and results showed that genotypes and other factors included in the logistic regression model significantly affect the prevalence of lameness in Holstein cows (P < 0.01). The probability of lameness incidence varied between 37 % and 99 % with parity. This recorded incidence is greater in winter and autumn than in the summer and spring.
