Table 2. Effects of THI on growth performance of finishing pigs

Item	Treatments		SEM	p-value
Temperature (°C)	23–24	32–33
Humidity (%)	35	80
THI1)	68	87
Day 0 to 14
Initial BW (kg)	50.44	48.81	0.52	0.058
Final BW (kg)	59.99	54.10	0.98	0.003
ADG (kg/d)	0.764	0.504	0.03	0.001
ADFI (kg/d)	1.676	1.182	0.15	0.050
G:F (kg/kg)	0.468	0.434	0.03	0.467

The data reported represent the means of 12 replicates (5 pigs/pen).
THI = (1.8 × temperature + 32) – [(0.55 – 0.0055 × relative humidity) × (1.8 × temperature – 26.8)].
THI, temperature-humidity index; BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; G:F, gain-to-feed ratio.
