Table 2.
Percentage of “long”, “wide”, “short”, and “narrow” lying postures for cows on pasture in Uruguay, within and between four herds on one farm. Herd 1 are pregnant, non-lactating cows, while herds 2, 3, and 4 are non-pregnant and lactating. Results of a chi-square analysis with adjusted residuals (AR).
| Posture | Herd 1 % (AR 1) | Herd 2 % (AR) | Herd 3 % (AR) | Herd 4 % (AR) |
|---|---|---|---|---|
| Long | 86.8 (4.1) | 84.6 (5.6) | 89.3 (10.5) | 83.3 (4.4) |
| Short | 2.6 (−1.3) | 5.1 (−1.0) | 3.7 (−2.5) | 11.1 (0.8) |
| Wide | 0 (−2.5) | 2.6 (−3.0) | 2.1 (−5.2) | 1.9 (−2.7) |
| Narrow | 10.5 (−1.9) | 7.7 (−3.4) | 4.8 (−6.6) | 3.7 (−3.5) |
1 if AR > 1.96 then % of lying postures is higher than expected; if AR < −1.96 then % of lying postures is smaller than expected.
