Short summary
This study investigated the effect of organic and inorganic chromium supplementation on growth and nutrient digestibility in chickens raised under chronic heat stress. The results show that 400 ppb organic chromium and 100 ppb inorganic chromium improve growth and protein digestibility. The use of organic chromium has demonstrated greater effectiveness, suggesting that it could be a useful strategy for nutritional management under adverse climatic conditions.
