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.
