Resumo
Morfometric studies of bovine and buffalo digits can help to understand the etiopathogeny
of digital diseases. This study described morphometric characteristics of digits
of Curraleira (Bos taurus), Pantaneira (Bos taurus) Nelore (Bos indicus) breeds of cattle
and Murrah buffalo (Bubalus bubalis) and stablish possible relation among the parameters
and digital infirmities. Were used ten animals of each breed and specie. Two limbs
were evaluated, a toracic and a pelvic, in a total of 80 distal limbs. Morphometric measurements
were obtained using a graduated paquimeter and angles using a metallic
protactor. The main parameters evaluated were hoof dorsal angle (A), dorsal wall length
(B), heel height (C), toe height (D), hoof length (E), hoof diagonal hoof (F), lateral digit
width (H), medial digit width (I) and medial digit length (J). For results averages comparison
among breeds were used Tukey test (p<0,05). Multivariate analysys for graphic
representations of canonic variables was used to express similarity of measures studied
among groups, using R software. Results shows tha bubaline present higher morphometric
measures for the variables B, C, D, E, F, G, H, I and J, only for variable A presented
lower measures comparing the bovine breeds studied. There is similarity between the
three breeds of cattle studied about toe height (D), lateral digit width (G) and medial
digit width (H), which differed of values observed in buffalo. It was concluded that digital
morphometry can influence the occurence of digital infirmities, but doesn´t act as an
isolated factor, needing interaction of other structural, environmental and management
factors for its occurence.
