Difference analysis of breast muscle weight (a), body weight (b), ATP content (c), and ATPase activity (d) among RR, RC, CR, and CC. For a-d, each dot represents a sample. The central red dot represents the mean value of the corresponding group. ***, **and * indicate adjusted P-values less than 0.001, 0.01, and 0.05, respectivelyBack to article page
