ABSTRACT
The experiment was performed on ISA broilers at big farm conditions. One day old chickens were randomly assigned to two poultry-houses with the capacity of 10600 birds each. Chromium was provided in the form of chromium enriched yeast (1.0 g Cr/kg yeast) given in doses of 0.2 mg Cr/kg diet. No significant differences in growth rate and only a slight decrease of feed conversion ratio was found in broilers receiving chromium-yeast supplement. However, these birds had a lower mortality rate comparied with the rate observed in the controls. Moreover, dietary chromium led also to an improvement of carcass composition. Organic chromium supplementation increased the weight of pectoral muscles and meat of these broilers contained less amounts of fat and cholesterol. These effects were accompanied by an insignificant increase of chromium concentration in the pectoral muscles of birds fed chromium supplemented diets, from 40 to 52 microg/kg wet tissue.
