CBH, cutaneous basophil hypersensitivity; SEM, standard error of the means.
1)
Data are least squares means of 6 observations per treatment.
2)
TN, thermoneutral condition; HS, heat stress condition.
3)
PC (positive control), basal diet; NC (negative control), basal diet; Gln, basal diet + 0.5% glutamine; Cr picolinate, basal diet + 500 ppb chromium picolinate; Vit C, basal diet + 250 mg/kg vitamin C; Bet, basal diet + 0.2% betaine; Tau, basal diet + 1.0% taurine.
a–c
Means with different superscripts within a column differ (p<0.05).
