In vivo measurement of claw horn toughness of Holstein Friesian cows

Foot structure is one of the most important determining factors of longevity. In this study the claw horn toughness was investigated in one herd of Jászapáti 2000 Mg. Zrt. Ten repeated measurements were taken during foot care on a determined area of the sole on 70 Holstein Friesian cows. The average value of claw horn toughness was 37.23 Shore D, with 4.45 standard deviation value. Results showed that cows with 3 or more lactations have significantly harder claw horn (Tukey HSD test, α = 0.05) than the others. Relationship was not found between locomotion scores and claw horn toughness. There was only a significantly loose-medium correlation (rrank = 0.44) between claw horn toughness and age.
