Abstract: This study determined the nutritive value of Indigoferra gerardiana, Marisine affricana, Impashion bicolor and Adhatoda vesica shrubs for ruminants. Five shrubs of each species were sampled and composite sample of leaves for each species was oven dried at 55oC for 48 h. Chemical analysis revealed that dry matter (DM) content varied from 24.3% (Adhatoda vesica) to 38.1% (Indigoferra gerardiana, Impashion bicolor). Maximum crude protein (14.7%) was observed for Marisine affricana while, minimum (15.6%) was noted for Impashion bicolor and Adhatoda vesica. Higher ash content (14.7%) and lower neutral detergent fiber contents (49%) were observed for Marisine affricana. Higher hemicellulose (42%) and lignin (7.9%) contents, and lower acid detergent fiber (22%) were observed for Impashion bicolor. The Ca, 1.01-2.7 %; P, 0.016-0.064 %; K, 0.47-1.29 %; Mg 0.012-0.032 %; Cu, 14-25 ppm; Zn, 12.4-41.3 ppm; Mn, 9-12 ppm and Co, 0.012-0.061 ppm were observed among shrub species. Potential intake rate (g/sheep/4min) was highest (64.5) for Indigoferra gerardiana, while, lowest (8.8) for Adhatoda vesica. Similar trend was observed regarding relative preference. Maximum in vitro DM digestibility (69.7%) and metabolizable energy (9.54 MJ/kg DM) were noted for Impashion bicolor, while, minimum in vitro DM digestibility (53.5%) and metabolizable energy (7.16 MJ/kg DM) were examined for Adhatoda vesica. Based upon the findings of present study, shrub species for use as ruminant feed were ranked as Marisine affricana > Indigoferra gerardiana > Impashion bicolor > Adhatoda vesica.
