* Minerals and vitamins (each kg contains): Vitamin A: 10,000,000 IU; Vitamin E: 70,000 IU; Vitamin D: 1,600,000 IU; Fe: 50 g; Zn: 40 g; Mn: 40 g; Co: 0.1 g; Cu: 10 g; Se: 0.1 g; I: 0.5 g. * RS = rice straw; PPCS = purple field corn stover. Anthocyanin content (cyanidin-3-glucoside equivalents, mg/L) = (A × MW × DF × 103)/(ε × 1); where A = (A510 nm–A700 nm)pH1.0–(A510 nm–A700 nm)pH 4.5; MW (molecular weight) = 449.2 g/mol for cyanidin-3-glucoside (cyd-3-glu); DF = dilution factor; 1 = pathlength in cm., ε = 26,900 molar extinction coefficient, in L·mol−1·cm−1, for cyd-3-glu and 103 = factor for conversion from g to mg.
