Table 4.
Estimates of breast blisters (%), live weight (g), summed footpad dermatitis scores, skin injuries (%) and rejections (N) for chickens hatched on-farm (OF) and in a hatchery (HC). Data were obtained from the slaughter plant.
| Parameter | Sex | OF1 | HC1 |
|---|---|---|---|
| Breast blisters (%) | M | 1.83 ± 0.51a | 3.67 ± 0.51b |
| F | 1.58 ± 0.51 | 1.61 ± 0.51 | |
| Live weight (g) | M | 2033 ± 39.3 | 2039 ± 39.3 |
| F | 1990 ± 39.3 | 2008 ± 39.3 | |
| Summed footpad dermatitis scores | M | 8.8 ± 3.1 | 12.3 ± 4.3 |
| F | 17.8 ± 6.2 | 21.7 ± 7.6 | |
| Skin injuries (%) | M | 2.50 ± 0.46 | 2.33 ± 0.46 |
| F | 1.14 ± 0.46 | 1.22 ± 0.46 | |
| Rejections (No.) | M | 4.68 ± 2.11 | 2.98 ± 1.40 |
| F | 4.03 ± 1.82 | 5.02 ± 2.24 |
a-bOnly the prevalence of breast blisters in males differed between the treatments (P < 0.05).
