A study was conducted to investigate the nutrient contents and microbial loads of different mixtures of Lablab purpureus and Panicum maximum. The five (5) experimental diets formulated were 100% P. maximum, 70% L. purpureus + 30% P. maximum, 50% L. purpureus + 50% P. maximum, 30% L. purpureus + 70% P. maximum and 100% L. purpureus. Forage samples were harvested at 8 weeks of age after sowing and arranged in a completely randomized design. Results showed significant differences (P0.05) by varied inclusion levels, however, calcium content decreased with increased levels of P. maximum. Highest (P0.05) across the diets. 100% L. purpureus had the highest (P<0.05) bacterial counts (3.48 x105 cfu/g) while the least values (2.86 and 2.68 x 105cfu/g) were similar for 30% L. purpureus + 70% P. maximum and 100% P. maximum, respectively. Grass-legume mixtures influenced chemical compositions and microbial loads, hence 30% L. purpureus + 70% P. maximum will make a good diet and enhance the performance of ruminants, if fed.
