Background: The effects of humic substances (HSs) on the carcass characteristics and meat quality traits of breast and thigh muscles were studied. Methods: In total, 200 pheasants were allocated to 4 treatments, each containing 50 birds. The control birds were fed a diet without additives (0% HS): the other treatment birds were fed diets containing HSs at 0.5, 0.75 and 1.0% from 1 to 90 days of age. At the end of the experiment, several carcass characteristics were measured and breast and thigh muscle samples were taken to determine the composition of several nutrients by standard laboratory methods and procedures. Results: The carcass weights of both males and females increased significantly (p <: 0.05) in the 0.50 HS and 0.75 HS groups after supplementation with HSs. The same effect of humic substances in the 0.50 and 0.75 HS groups was found in the weight of breast and thighs (p <: 0.05). Significantly (p <: 0.05), the highest carcass yield in males and females was found in the 0.50 HS group. Conclusions: Feeding with a diet containing HSs can have a beneficial influence on the carcass parameters, decrease the crude fat content in the meat and change the profile of bioactive fatty acids in the breast and thigh muscles of broiler pheasants.
