The objective of this study was to determine the chemical composition and in situ ruminal degradability of normal and brown midrib (bmr) forage pearl millet [Pennisetum glaucum (L.) R. Br.] grown in southwestern Quebec conditions. Forage was harvested twice during the season. Relative to normal genotype, bmr millet contained less (P < 0.05) neutral detergent fiber (NDF) and acid detergent lignin and more (P < 0.05) crude protein (CP). Fiber fractions were similar for the two harvests. However, CP content was higher (P < 0.05) in the first than the second harvest. In situ ruminal degradabilities of DM, CP and NDF were all higher (P < 0.05) for bmr than normal forage millet and were not affected by harvest.
