TABLE 3.

Effect of rearing temperature and feed restriction on mortality (%) of Cobb 500 male broiler chickens.

Treatments1	Time period (day)
	0–28	29–42	0–42
CTL	0.89	1.34	2.23
CHS	3.12	0.93	4.01
PF	1.78	0.46	2.23
SEM2	0.96	0.58	1.12
P-value3	0.282	0.573	0.444

¹Treatments include: (1) control (CTL): birds raised under normal temperature (23°C) from day 29 to 42 and had free access to the diet; (2) cyclic heat stress (CHS): birds exposed to high temperatures (8 h/day at 35°C; from 9:30 am–5:30 pm) from day 29 to 42 and had free access to the diet; (3) pair-fed (PF): birds raised under the same condition as CTL group, but fed the same amount of feed as CHS group from day 29 to 42. All birds fed the same corn-soybean meal basal diet.

²SEM: pooled standard error of means.

³P-value: based on one-way ANOVA.
