Resumo
Radiographic and computed tomography (CT) findings may contribute to the diagnosis and prognosis of diseases based on knowledge of digits morphometric reference values. Some breeds of cattle and buffaloes still require determinations of these values for the digits. Thus, the objective with this research was to compare and correlate the condyles and phalanges, on radiographic images, and measurements of internal and external structures of the hoof, using computed tomography, to buffaloes and cattle breeds Nelore, Curraleira and Pantaneira. After submission and approval of the project by the Ethics Committee in Research of UFG, Protocol No. 090/2011, 114 were used digits of the locomotor members cattle and buffaloes without lameness in foot. Members were collected from an abattoir under Federal Inspection, disarticulated joints carpal/metacarpal and tarsal/metatarsal and by lot were used only thoracic and left pelvic limbs. For radiographic placements used were dorso-palmar/plantar and members of the CT scans were positioned with the palmar or plantar portion of the table CT scanner and the images obtained by transverse sections. From the radiographic images was measured the length of the condyles, proximal, middle and distal phalanges and the entire condyle and digit together. CT measurements were carried out: thickness of the sole; distance between the inner wall of the sole the distal phalanx; distance between the inner wall of the hoof the distal phalanx; thickness of the wall hoof; base length of the distal phalanx; side length of the distal phalanx; height of the distal phalanx, length of the sole; length of the dorsal hoof wall; heel depth, angle between the lengths of the wall and the sole length and angle between the side and base of the distal phalanx. To compare the means between the races was used the Tukey test (p<0.05). The Pearson correlation was performed between the weight and all measurements and multivariate analysis tested the similarity of the groups. The results of radiographic verified for the buffaloes, the greater length of the proximal phalanx in forelimbs (Lateral: 6.28 ± 0.13; Medial: 6.31 ± 0.18) and the hindlimbs (Lateral: 6.48 ± 0.15; Medial: 6.38 ± 0.17). The lengths of these phalanges did not differ (p> 0.05) between the Pantaneiro and Curraleiro digits in the forelimbs. In CT scans measures the length of the base (Lateral5.58 ± 0.18; Medial 6.52 ± 0.32 / Lateral:5.39 ± 0.09; Medial:6.43 ± 0.18) length lateral (Lateral:5.44 ± 0.21; Medial:6.02 ± 0.24 / and Lateral:5.3 ± 0.17; Medial:6.07 ± 0.27) and height (Lateral: 3 , 98 ± 0.16 and Medial: 4.15 ± 0.12 / Lateral:3.93 ± 0.11; Medial:4.01 ± 0.12) of the distal phalanx, had the highest measured in buffalo and did not differ (p> 0.05) between breeds of cattle. Thus, we conclude that the buffaloes have larger dimensions of the condyles and phalanges. In tomographic imaging, measures the hoof were similar between Nelore and Curraleiro in forelimb and between Curraleiro and Pantaneiro in the hindlimb.
