AFE = age at first egg, BWFE = body weight at first egg, WFE = weight of first egg, BWTA = body weight at 300 days of age, EWTA = egg weight at 300 days of age, and EN = total number of eggs at 300 days of age. LH means Luhua chickens (N = 232), and DX means Dongxiang blue-shelled chickens (N = 279). Results are expressed as least square means ± standard errors.
