Abstract

Two trials were carried out to evaluate the potential of Tephrosia bracteolata (TB), Tephrosia candida (TC) and Tephrosia linearis (TL) for animal feed In an 18 week growth experiment, Tephrosia species differed (P<0.05) in leaf number (LN) and stem height (SH). TB and TL had apparent (P<0.05) early and persistent growth than TC until weeks 12-18 when they retarded in growth at the commencement of flowering. TC however, increased geometrically in LN and SH. There were significant (P<0.50) differences among the species in dry matter (DM) and acid detergent fibre (ADF). The DM, CP, NDF, ADF, EE and ash range from 30-41.8, 24-26.5, 62.5- 68.5, 45.8-48.4, 2.3-26 and 5.6-6.2% respectively. Calcium and sodium were highest (P<0.05) in TB and TL species were not significantly (P<P.05) different in degradation characteristics. Lower amount of crude protein (10-14.81%) was released in the 3 Tephrosia species. As a result of rapid growth, high nutritive values and easily degradable nutrients of Tephrosia shrubs, ruminants could benefit immensely from the plants.
