The aim of this work was to evaluate the effect of dietary chromium supplementation on performance, carcass yield, meat quality, cholesterol level on the breast and blood biochemical parameters on broilers. It was used a complete randomized experimental design with five levels of chromium tripicolinate (0, 150, 300, 450 and 600 µg/kg of chromium) and six replicates with 50 broilers per experimental unit. The use of chromium tripicolinate had no effect on the performance of broilers. The levels of chromium did not change the carcass yield neither the breast pH of the broilers at 42 days of age. At evaluation of dry matter composition, crude protein and ether extract of breast meal, only the percentage of ether extract was quadractly affected by the dietary chromium level. Chromium level of 218.2 µg reduced the ether extract percentage by 7.03 when compared to the lack of chromium. The addition of chromium in the diets did not influence the total cholesterol level in the breast meat but it did change the levels of HDL at 14 old, the VLDL and triglicerides at 21 days old. The dietery suplementation of chromium did not influence the performance neither the carcass yield. Levels of chromium ranging from 218.2 to 360.3 ì g affects fat meat and levels of blood lipids of broiler chickens.
