Evaluation of claw dimensions in crossbred heifers of Kerala

Abstract

Hoof disorders markedly reduce productivity and overall performance of ungulates, with lameness posing a significant challenge in the dairy sector. This study aimed to assess the dimensions of claws in crossbred heifers in Kerala and to establish essential foundational data in this domain. The study, involving six crossbred heifers, encompassed the measurement of parameters like toe length, toe height, toe angle, sole length, sole width, and heel height using a defined methodology. The mean toe length in the forelimb (6.16±0.03 cm) was significantly greater than that in the hindlimb (5.84±0.05 cm). Among the heifers, the highest toe height was recorded in the right lateral claw of the forelimb (5.40±0.03 cm), while the lowest was in the left medial claw of the hindlimb. The overall mean sole length of the forelimb (9.11±0.10 cm) was significantly greater than that of the hindlimb (8.67±0.10 cm). Preserving an ideal claw conformation in line with optimal dimensions is critical for averting claw-related challenges and promoting animal welfare, underscoring the importance of regular hoof maintenance.
