Resumo
The morphometric study of the digits of cattle and buffaloes can contribute to understanding the pathogenesis of foot diseases and may serve as a valuable tool in the selection of animals with the intention of reducing the harm caused by these bulky disease in cattle. Several breeds of cattle and buffaloes still need further studies to determine such measures. The aim of this study was to describe and compare the measurements of the digits of cattle in CurraleiroPantaneira and Nellore and Murrah buffaloes. After submission and approval by the Ethics Committee of the Universidade Federal de Goiás, Protocol No 189/11, were used 80 ends distal limb locomotion of healthy cattle and buffaloes. Members were obtained in Refrigerator under Federal Inspection, disjointed carpal-metacarpal joints and tarsal-metatarsal being used only the fore and hindlimbs rights. The morphometric measurements were obtained with the aid of a mechanical caliper graduated and angles of tweezers conferred through metal protractor. The main parameters evaluated in digital chest and pelvic limb of each animal was measured both using the digit digit as medial side were dorsal hoof angle (A), dorsal wall length (B), the bead height (H), clip height (D), the hull length (L), diagonal length of the hull (F), the digit lateral width (G), the digit width medial (M), length of the digit side (I) and medial digit length (J). For comparison of average results between races we used the Tukey test (p <0.05). Multivariate analysis for the graphical representations of canonical variables was used to express the similarity of the variables between the groups in which they used the software R. The average weight obtained at the end of the experiment each group of cattle and buffaloes was analyzed to establish a possible correlation between the measures of the digits and the size of the animals used in the experiment. The results revealed that the major buffaloes present morphometric measurements for the variables B, C, D, E, F, G, H, I and J, only the variable A (dorsal hoof angle) that have lower angles to different breeds cattle studied. We conclude that there is evidence that morphometrics influence the occurrence of illnesses digital, but does not act as an isolated factor, requiring interaction with other structural factors, and environmental management for the manifestation of these diseases.
