Nutritive value and acceptability by goats of selected indigenous browses from semi-arid areas of Kenya

摘要

The feeding value and palatability of five browses foliage’s ( Balanites aegyptiaca, Maerua angolensis, Acacia brevispica, Grewia hostii and Berchemia discolorfrom semi-arid area were evaluated for their potential as supplements to Rhodes grass (Chloris gayana) hay. The crude protein (CP) content ranged from 41.4 gkg-1dry matter (DM) in Rhodes grass to 162 gkg-1DM in Berchemia discolor. Maerua angolensis had the lowest fiber content. Total extractable phenolics (TEPH) and condensed tannin (CT ranged from 6.1 to 52.3 gkg-1DM and 2.0 to 43.8 gkg-1DM, respectively. Relative palatability indices were: Acacia brevispica Balanites aegyptiaca Grewia hostii Berchemia discolor Maerua angolensis Chloris gayana. Maerua angolensis was of low palatability compared to other browse species.
