Objectives: To determine the various constituents of commercial, broiler chicken feed and the presence of these constituents in their meat. Methods: The experimental study was conducted at the Pakistan Council of Scientific and Industrial Research laboratory, Karachi. Samples of commercial broiler chicken feed and meat were collected in 2015 from a large poultry farm that supplies chicken meat to various suburban areas of the city. Another set of organic chickens were bred in an animal house. The samples of feed, meat and droppings were then analysed for the estimation of basic constituents and additives in the laboratory. Data was analysed using SPSS 20.0. Results: The constituents were measured in 26 samples of chicken meat from each group. Calories (p<0.01), amount of protein (p<0.01), total fats (p<0.05), cholesterol (p<0.01), saturated fats (p<0.01), monounsaturated (p<0.05) and polyunsaturated fats (p<0.01) were significantly increased in commercial broiler chicken compared to that of organic chicken meat. The commercial chicken feed was found to contain crude carbohydrate, crude protein, crude fat, crude fibre, vitamins, amino acids, premixes of vitamins and toxicities of roxarsone, melamine and pesticides. Additive constituents were also present in the commercial chicken meat. These components were absent in organic chicken meat and droppings which suggests that they were absent in their feeding contents. Conclusion: Organic chickens were found to be safer for consumption than commercial chickens.
