Effects of Inoculation with Different Rhizobia on the Nutritional Value and Ruminal Fermentation of Desmodium intortum

Rhizobia inoculation is widely used in legumes to improve the yield and quality of forage. However, symbiotic interactions different are specific. The search for efficient strains plays an important role legume forage practical production. In this study, Desmodium intortum was first inoculated with rhizobia from regions, then production traits, nutritional quality, fermentation D. rumen were evaluated according strains. results showed that, compared control, significantly increased number nodules, shoot fresh weight, crude protein content, plant yield, ether extract content intortum, R3 strain (Bradyrhizobium elkanii) these values by 61.0%, 29.6%, 16.1%, 62.9%, 30.4%, respectively. basal diet Pennisetum purpureum Rich. × P. americana King grass cv. Reyan No.4, added (75:25), combination R5 rumen’s ammonia-nitrogen (NH3-N) levels vitro dry matter digestibility (IVDMD): contents NH3-N IVDMD 50.1% 12.3%, respectively, while them 50.9% 15.4%, Based on a comprehensive evaluation through principal component analysis, ranked overall. These support development competitive inoculants indigenous as strategy value ruminal fermentation.
