a, b, c Means within a row with different superscripts significantly differ (Tukey’s test; P < 0.05)
TN (control): Thermoneutral treatment, fed basal diet; TN + PHY: Thermoneutral treatment fed basal diet + 1 kg/ton feed PHY; HS: Heat stress treatment, fed basal diet; HS + PHY: Heat stress treatment, fed basal diet + 1 kg/ton feed PHY.
HDL chol: High-density lipoprotein cholesterol; LDL chol: Low-density lipoprotein cholesterol; VLDL chol: Very low-density lipoprotein cholesterol; A/G ratio: albumin/ globulin ratio
Data are means ± SEM (standard error of the mean)
