The protein digestibility of seven ungerminated and germinated dried finger millet (Eleusine coracana) grain was determined in this study. All the finger millet varieties had low to medium tannin content, ranging from 0.1% Catechin equivalents (CE) in Dalle 1 to 0.6% CE in EKR 228. For raw ungerminated finger millet, the mean protein digestibility was 58.9%. It ranged from 40.5% in P224 to 86.3% in EKR 227. EKR 227 had significantly higher digestibility (P<0.05) than P224. Cooking drastically reduced the digestibility of ungerminated fingermillet. The protein digestibility of cooked finger millet ranged from 1.7% in Dalle 1 to 25% in EKR 227, with a mean of 9.0%. There were significant differences (P<0.05) in protein digestibility of cooked ungerminated finger millet grain. The mean protein digestibility of the raw germinated millet was 53.0%, ranging from a minimum of 16.9% in P224 to a maximum of 79.1% in EKR 227. The variety P224 had significantly lower protein digestibility (P<0.05) than P283 and EKR 227. The mean protein digestibility of the cooked germinated finger millet grain was 55.7%, and did not significantly differ (P >0.05) from that of the raw germinated grain.
