Significant reductions in cortisol and hsp70 were observed after 30 days of chromium yeast supplementation under heat stress conditions.
Cortisol levels dropped alongside hsp70 expression at the highest chromium yeast dose, highlighting physiological benefits for lambs.
Animals received varying doses of chromium yeast in a factorial design, assessing their effects on stress biomarkers over time.
Short-term protective effects against heat stress were noted, but these effects were not sustained beyond 30 days.
