Evaluation of Selected Species of Fodder Trees Cultivated for Feeding Ruminant Animals in the Hills of Nepal

Abstract

Leaves and twigs from four species of tree fodders, Aetocarpus lakoocha (AL), bauhinia  purpurea (BP), Garuga pinnata (GP) and Ficus sroxburghii (FR), cultivated widely for  feeding ruminants in the hills of Nepal and maintained at the Agriculture Research Station  (Goat), Bandipur were investigated for there chemical composition, and nutrient intake,  digestibility, and growth rate in growing female goats. Differences occurred between species  of tree fodders on nutrient composition, which contained 286, 342, 312, and 263 g/kg DM;  174, 98, 116 and 178 g/kg total ash; 137, 163, 140, and 119 g/kg CP; 440, 458, 437, and 451  g/kg NDF; 383, 407, 382, and 406 g/kg ADF; 177, 135, 181, and 143 g/kg ADL; 19.5, 21.6,  20.9, and 29.3 g/kg Ca; and 2.2, 2.8, 2.4, and 2.5 g/kg P on DM basis for AL, BP, GP, and  FR, respectively. The DM intake was higher for goats fed AL (432 g/d) and GP (428 g/d)  than BP (342 g/d) or FR (306 g/d). Nutrient digestibility was higher for goats fed AL and  GP, except Ca, which was higher for goats fed FR. Similarly, highest daily weight gain was  observed for goats fed AL (71 g/d) and GP (64 g/d) than either of BP (54 g/d) or FR (30  g/d). Overall, leaves and twigs from these tree fodders supported moderate growth, but may  not be advisable for maximum production.
