Table 2.
Distribution based on the Temperature Humidity Index (THI) of the ten deliveries of Italian heavy pigs transported approximately for 30 min under commercial conditions. For each class of THI, identification (ID) of the deliveries, number of pigs, mean and standard deviation (s.d.) of outdoor temperature (T), relative humidity (RH) and THI at unloading are shown.
| THI Class * | Deliveries ID | Pigs | T (°C) | RH (%) | THI | |||
|---|---|---|---|---|---|---|---|---|
| No | Mean | s.d. | Mean | s.d. | Mean | s.d. | ||
| 1 | 1, 2, 4, 5 | 560 | 5.6 | 1.1 | 76.6 | 2.8 | 43.5 | 1.5 |
| 2 | 3, 6, 7 | 420 | 12.8 | 2.4 | 71.7 | 4.6 | 55.5 | 3.5 |
| 3 | 8, 9, 10 | 420 | 19.7 | 1.8 | 67.0 | 12.3 | 65.6 | 2.0 |
* THI classes were obtained by the CLUSTER procedure on the basis of THI values and the deliveries were allocated into the classes by the FASTCLUS procedure of SAS [23].
