Effects of dietary steam-exploded pine particles supplementation on the rectal temperature of thermoneutral and heat-stressed broiler chickens.

Treatments	Rectal Temperature
	Before	After
0% NT	41.73 ± 0.03	41.88 a ± 0.05
0% HS	41.87 ± 0.04	43.75 b ± 0.25
1% HS	41.78 ± 0.05	43.52 b ± 0.23
2% HS	41.80 ± 0.04	43.30 b ± 0.20
p-value	0.157	0.001

Chickens were fed with diets containing 0% (control), 1%, and 2% shredded, steam-exploded pine particles (SPP) from the 8th day to the 41st day of age. On 41st day, birds were either kept at thermoneutral temperature (21.0 °C) and provided control diet (0% NT) or heat-stressed at 31.0 °C for six hours and supplemented with 0% (0% HS), 1% (1% HS) and 2% (2% HS) SPP in diets. “Before” and “After” indicates rectal temperature taken before starting and after completing six hours of heat stress respectively. Data show mean ± SEM (n = 6). ^a,b: Different letters indicate significant differences (p < 0.05). Abbreviations: NT, normal temperature; HS, heat stress.
