The aim of this paper was to determine the standard measures of the hoof claw: length, height, heel height and hoof surface in breeding bulls as indicators for the correction of hooves. The paper deals with the healthy and pathologically altered hooves of 11 Simmental bulls, owned by the Centre for Reproduction in Livestock of Croatia, Križevci. After measuring these dimensions, their mean values were calculated, and a statistically significant difference was determined between values within each group of parameters and a certain correlation between the mean values and weight of each bull. The average length of the front limb hooves in the bulls studied was 9.39 cm, and the average length of the hind limb hooves was 9.92 cm. The average height of the front limb hooves was 8.65 cm and average height of the hind limb hooves was 8.63 cm. The average height of the front limb hoof heel of the bulls studied was 5.93 cm, and the average height of the hind limb hoof heel was 5.09 cm. The average surface of the front limb hooves was 122.46 cm² and the hind limb hooves 102.49 cm². The degree of correlation between the hoof length and body mass in front limb hooves was fourfold higher than the one in hind limb hooves. The trimming of the front limb hooves was rendered difficult by the live animals’ restlessness and the fact that they lean on one front limb hoof which is overburdened by the front part of the body during trimming and the horn of the front limb hooves was much firmer than of the hind limb hooves. A negative correlation between the obtained measurements of the heel height in front and hind limbhooves and body mass indicates that the increase in body mass overburdens the legs, and therefore their heel parts. The average surface area of the front limb hooves was 20 percent larger than the surface area of hind limb hooves. A significant and a very high correlation existed for the total area of hooves in relation to body mass of breeding bulls, and this correlation was more pronounced in the hoof surface of the front limb and body weight than the surface of the hind limb hooves and body weight. Hoof area increased with increasing body weight and the degree of correlation was more pronounced in the front limbs than in the hind limbs. This is, most probably, related to the fact that the front limb hooves suffer greater physiological load. The correlation of the total surface area of all limb hooves and body mass was also high.
