Abstract:
Background: Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy bufalo popula-tion in Egypt. Furthermore, the optimum measurements for claw trimming in bufalo are unknown. A cross-sectional cadaver study was conducted where 135 pair bufalo hind feet were collected from 4 slaughterhouses and examined for the presence of claw lesions. The proportion and associated 95% confdence interval (CI) of each type of lesion were calculated. A separate set of healthy claws (n = 26) underwent ultrasonography (US) and computed tomography (CT ). The agreement between US and CT measurements was assessed using Passing-Bablok regression and intraclass correlation coefcient. The CT measurements were used to calculate trimming recommendations. Results: At least one lesion was identifed in 242 claws (89.6%, 95% CI = 85.4–93.0). In healthy claws, poor to moder-ate agreement was identifed between US and CT measurements which could be due a sample size of the study. The average ± standard deviation (SD) minimum recommended external wall length of the lateral and medial claws in heifers was 7.1 ± 0.36 cm and 7.5 ± 0.35 cm, respectively. The average ± SD minimum recommended external wall length in bufaloes over fve years of age was 8.2 ± 0.27 cm and 8.4 ± 0.39 cm for the lateral and medial claws, respectively.Conclusions: The study found a high prevalence of claw lesions in bufalo in Egypt, the clinical signifcance of which requires further elucidation. Recommended measurements will help guide claw trimming in bufalo to minimise lesions.
