¹The experiment was conducted with day-of-hatch male Cobb chicks with 9 replicate pens per treatment and 8 birds per pen. Three animals per pen (n = 27) and 5 animals per pen (n = 45) were sacrificed on d 28 on d 42, respectively, for subsequent analysis
²Dietary treatments included: Control, basal diet; Butyrate, basal diet supplemented with 1 g/kg microencapsulated sodium butyrate; FSK10, basal diet supplemented with 10 mg/kg of 20% forskolin (FSK)-containing Coleus forskohlii (CF) extract; Butyrate+FSK10, basal diet supplemented with 1 g/kg microencapsulated sodium butyrate and 10 mg/kg CF extract
³Statistical significance was determined using one-way ANOVA, followed by post hoc Tukey’s test. The values in a row not sharing a common superscript are considered significantly different (P < 0.05)
