Table 5.
Comparison of claw volume, sole surface area, dorsal wall length, and hoof horn hydration between fissured and non-fissured claws from the same claw position on the same cow
| Variable | Mean fissured claws (s) | Mean non-fissured claws (s) | t-value | P-value |
|---|---|---|---|---|
| Claw volume (cm3) (n = 15) | 371.3 (78.8) | 373.3 (99.2) | −0/13 | 0.90 |
| Sole surface area (cm2) (n = 15) | 15.1 (2.5) | 16.1 (2.1) | −1.82 | 0.08 |
| Length of dorsal wall (cm) (n = 10) | 108.3 (8.2) | 105.2 (10.2) | 1.89 | 0.09 |
| Hoof horn hydration (%) (n = 33) | 23.7 (4.0) | 21.3 (2.8) | 4.02 | 0.0003 |
Note: The n-value for the comparative tests is not constant, this is due to the fact that in a number of cases measurement of claw size either by volume, length of the toe or sole surface area could not be measured due to the abnormal shape of the claw (corkscrew claw abnormality, etc.)
s — standard deviation
