Age of 150 days in each group randomly selected 40 (half male and half female), slaughter, pork, and compared with growth and carcass and meat quality and economic benefit indexes were determined. The results showed that show pheasant of the various stages of weight and weight was significantly lower than that of the cyan-shank partridge chicken (P 0.05 or P 0.01). Population death number and the death rate is lower than the cyan-shank partridge chicken; slaughter performance and cyan-shank partridge chicken difference was not significant (P 0.05); the muscle inosine monophosphate significantly was higher than that of cyan-shank partridge chicken (P 0.01), intramuscular fat content is lower than the cyan-shank partridge chicken, and the difference was significant or extremely significant (P 0.05 or P 0.01).Through the comprehensive economic benefits of two varieties of analysis, show the pheasant breeding efficiency was significantly higher than that of young chicken feet.
