In order to investigate the reasonable shape of hoof in fattening young steer of japanese black cattle，8 regions of hoof after trimming were measured with 5 beef cattles kept in paddok stall barn.
1) Measures of each region in hoof were as follows :
Front height hoof of front legs 59cm, hoof of hind legs 6.1cm hind height : 4.3cm, 3.8cm, upper length 8.6cm, 8.1cm, lower length : 14.0cm, 12.8cm, length of front incline 6.9cm, 7.6cm, lower width : 11.6cm, 10.1cm, higher width : 10.8cm, 9.9cm, angle of inclination : 52.4゜, 52.9゜, volume : 478<cm>^^^3, 393<cm>^^^3.
2) Prorortion of each measures in hoof to upper length were as follows : Front height : hoof of front legs 68.7%, hoof of hind legs 75.5%, hind height : 49.4%, 46.7%, lower length : 162.3%, 157.6%, length of front incline : 79.9%, 94.5%, lower width : 137.8%, 124.1%.
