The invention aims to provide a maternal-body low-protein method for improving the meat flavor of offspring. The method takes protein as a main way and improves the nutritive value and meat quality of offspring chicken by changing the amount of feeding a maternal generation. According to fed daily rations in different protein levels (high protein level, normal level and low protein level), 96 egg-laying hens are divided into three daily ration groups at random; when the egg-laying rate of maternal bodies reaches 50 percent, artificial insemination is performed; when the egg-laying rate of the maternal bodies reaches a peak, people begin to collect hatching eggs; and the collected hatching eggs are incubated. The method has the function of improving the meat quality of chicken, wherein the low protein level of the daily rations for the hens can improve the meat flavor of the offspring, and does not change the muscular nutritive value of the offspring at the same time; in addition, the reduction of the protein level of the daily rations for the hens can not affect the liver health and functions of the offspring, but can save raising cost.
