Abstract：To evaluate the effect of house fly Musca domestica L. maggots and pupae on the quality and flavor of Qingyuan chickens, and to provide new food instead of fish powder for chicken production, 150 chickens divided into five groups at random, were fed with different proportions of house fly larvae, pupae in commercial chicken diets. The chickens in the control were fed with fish powder or commercial chicken diets. The results indicated that therewere no significant differences in the weight of spleen and bursa of the chickens between those fed with house fly larvae, pupae, fish powder or commercial chicken diets. The mortality of the chickens fed with house fly larvae or pupae was significantly lower than those with fish powder and commercial chicken diets. The water loss in the chicken meat fed with the fly was also significantly lower than that fed with non- insect diets. When the chickens were fed with the house fly, the flavon of the chicken meat was greatly improved and the contents of amino acids in the chicken meat increased, especially of aspartate, threonine and serine, which are considered as an important indicator of the chicken flavon. These results showed that house fly larvae and pupae can be used as a useful diet for chicken production by improving the anti- disease capacity and the flavon of the chickens.
