Supplementing chromium from chromium propionate in the diet showed a positive effect on feed conversion ratio and breast meat yield of birds subjected to cyclical heat stress. Chromium supplementation may alleviate the negative effects of stress on growth, performance and carcass traits.
Based on extensive research conducted by Kemin Industries, the Food and Drug Administration (FDA) Center for Veterinary Medicine (CVM) approved the use of chromium propionate as a source of chromium in broiler diets. Chromium propionate is the newest trace mineral approved for broiler diets in more than 40 years. The food additive petition process through the FDA can be time consuming and expensive but is designed to generate necessary data to sell safe, efficacious ingredients to the marketplace.
Chromium supplementation has been shown to improve broiler body weight, weight gain and carcass yield by decreasing the impact of stressors experienced by the bird. The objective was to evaluate the effects of chromium propionate (Cr Prop) on broiler performance and livability in a commercial antibiotic free complex. The supplementation of Cr Prop improved average feed conversion ratio (FCR) by 2 points compared to historical data. Moreover, Cr Prop improved livability by 0.45%.
