Description
Data were analysed on 6 claw measurements, claw shape, leg posture scores and 8 claw disorders of 725 German Simmental (GS) daughters of 18 GS bulls. The statistical model included the fixed effects of herd, chest girth, calving period, nutrition, claw care rating, and month of measurement, and the random sire effect. The claw measurements, which are illustrated in a diagram, were linear, angular and area measurements. Herd was the most important fixed effect. The h2s of (1) claw measurements, (2) leg posture and claw shape, and (3) claw disorders were 0.17 0.08 to 0.66 0.21, 0.08 0.06 to 0.50 0.18 and 0.10 0.07 to 0.35 0.14 resp. For Pt. 2 see pp. 208-221 of the same number of the journal
