Browse, chemical composition, forage acceptability, goats, grazing, supplementationAbstract
The study was carried out to investigate the suitability of utilizing Tephrosia species in the feeding of small ruminant livestock. It involved the laboratory assessment of nutritive and anti-nutritive components of three Tephrosia species. Forage acceptability of the species using cafeteria method with eight adult goats and effect of feeding the most preferred specie to grazing goats. The species studied were T. candida (Roxb) D. C., T. purpurea (L) Pers, and T. vogelii (Hemsley) A gray. These values are within the ranges considered adequate for goats. The concentration of tannins, saponins, oxalic acid and phytic acid were low. Differences in the relative preference index (%) were significantly different with an average of 80.4 for T. purpurea, 67.7 for T. vogelii and 19.9 for T. candida. Total body weight of grazing animal supplemented with T. purpurea was significantly higher than those without supplement by 2.19kg. The results showed that these Tephrosia species have good level of nutrients save level of anti-nutritional factors and therefore can be used as supplement to animals grazing on poor paddocks.
