Table 1.
Distribution of age and days post-partum of animals diagnosed with left displacement of the abomasum (LDA) and either no claw lesion (LDA − CLAW) or at least one claw lesion (LDA + CLAW). Results with a p-value < 0.05 were considered statistically significant and are printed in bold letters. As data was normally distributed, mean and standard deviation (SD) are given.
