ABSTRACT

 

Taymouri A, Dehghani S, Meimandi A., Effect of grazed versus penned sheep on hoof morphometrics, Onl J Vet Res., 24 (6):328-331, 2020. Hoof lesions and lameness reduce milk, meat, wool and fertility in sheep. We compare hoof morphology and lameness in grazed and penned sheep. Hoof from grazed sheep were collected at slaughter, measured and lesions recorded before and after trimming. Hoofs with lesions were X-rayed after trimming to detect changes in digit bones and joints. For penned sheep, gait and limb morphometrics, hoof lesions were recorded as per Greenough, trimmed and then, further lesions recorded. We found that morphometrics before and after trimming changed (P < 0.05) in both groups. Results suggested that gender affected (P < 0.05) morphometrics of hind legs after trimming hooves but not between right and left forelegs. Hind limb morphometry was significantly different (P<0.05) between penned and grazed sheep but no differences in bones and joints of digits by X-Ray. We find that hoof morphometry before and after trimming, changes, suggesting that sheep should be trimmed regularly to reduce lameness.

Keywords: hoof, lameness, sheep, trimming, morphometry.
