Impact of CT occurrence on piglet production, piglet mortality and the splay legs syndrome
| Farm | WP/S/Y before OCT | WP/S/Y during OCT | Mortality of CT-affected piglets | Splay legs observed in CT-affected piglets |
|---|---|---|---|---|
| A | 25.5–26.5 | 23.57 | Up to 30% | Yes |
| B | 24.5 | 17.2–19.6 | i.d. | No |
| C | 25.6 | 22.8–24.0 | i.d. | Yes |
| D | 26.2 | 26.0 | 0.6% | No |
| E | 26.5 | 23.45–23.86 | Up to 25% | Yes |
| F 2013a (2016) | i.d. (24.1) | i.d. (24.0–24.05) | i.d. (<0.6) | i.d. (no) |
| G | i.d. | i.d. | i.d. | i.d. |
WP/S/Y: weaned piglets per sow and year; OCT: occurrence of congenital tremor; CT: congenital tremor; i.d.: indeterminate, due to inexistent or inconsistent records.
