a,b Mean values within a row with different superscripts differ significantly (p < 0.05). 1 Pre- and post-weaning: calves were given treatments at ages 28 and 42 d, and at ages 56 and 80 d. Overall: calves were given treatments at ages 28, 42, 56, and 80 d. 2 CON = no yeast or flavonoids fed; ADY = Candida tropicalis as supplement; FLA = mulberry leaf flavonoids as supplement; YF = combination of Candida tropicalis and mulberry leaf flavonoids as supplement; BHBA = β-hydroxybutyric acid; EGF = epidermal growth factor. 3 SEM = standard error of the mean.
