Source 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 were collected from Shandong, Shanxi, Hubei, Hunan, Sichuan, Henan, Hebei, Xinjiang, Anhui, and Liaoning province of China, respectively.

GE = Gross energy; DE = Digestible energy; ME = Metabolizable energy; ATTD = Apparent total tract digestibility; ME/DE = The ratio of ME to DE.

SEM = Standard error of means. Means within the same row lacking a common superscript letter differ significantly (p<0.05).
