Table 4.

Effect of the interaction between the class of the Temperature Humidity Index (THI) and deck level on the maximum surface temperature (°C) recorded at unloading by a thermal camera on the ocular region of Italian heavy pigs transported approximately for 30 min under commercial conditions (least square means).

THI Class *	Deck Level						SE
THI Class *	1	2	3	4	5	6	SE
1	32.8 ^{x ab}	33.2 ^{x a}	32.0 ^{x b}	33.2 ^{x a}	33.0 ^{x ab}	32.4 ^{x ab}	0.60

^a^{, b}: different superscript letters in the same row are different at p < 0.05; ^x^{, y, z}: different superscript letters in the same column are different at p < 0.05. SE: standard error. * In THI classes, the following deliveries (ID) were included: 1, 2, 4 and 5 in class 1; 3, 6 and 7 in class 2; 8, 9 and 10 in class 3.
