Table 7.
Effects of enrichment treatments on skin lesion scores in focal sows. Lesion scores were measured on day 1 (before enrichment) and day 12 of each treatment period.
| Lesion Scores * | Treatments | |||||
|---|---|---|---|---|---|---|
| Control | Constant | Rotate | Stimulus | SEM | p-Value | |
| Day 1 Total | 3.54 a | 2.50 a | 3.32 a | 5.41 b | 0.57 | 0.002 |
| Shoulder Day 1 | 1.11 a | 0.47 ab | 0.83 ab | 1.40 c | 0.18 | 0.001 |
| Side Day 1 | 0.63 a | 0.33 a | 0.58 a | 0.91 b | 0.13 | 0.028 |
| Day 12 Total | 4.01 | 3.42 | 4.50 | 4.11 | 0.27 | 0.446 |
| Shoulder Day 12 | 0.77 | 0.63 | 1.00 | 0.80 | 0.16 | 0.465 |
| Side Day 12 | 0.40 | 0.46 | 0.51 | 0.41 | 0.11 | 0.908 |
ab LS Means with a different superscript within the same row are significantly different (p < 0.05). * Lesion scores were done using a scale of zero to three (0 = no injury, and 3 = severe injury) on 11 regions on the right and left side of sows. Total = sum of lesions for all 22 body regions.
