Abstract
The current study was undertaken to evaluate the chemical composition, in vitro dry matter degradation and gas production of four browse species (Azadirachta indica, Ficus exasperate, Synedrella nodiflora and Boerhavia diffusa). The results showed that ash, crude protein, dry matter and neutral detergent fibre contents were significantly different (p˂ 0.05) among all the species. A. indica had the highest crude protein concentrations exceeding 30%. In vitro gas production was different (p< 0.05) between B. diffusa and S. nodiflora from 9 to 48 h of incubation. S. nodiflora however, recorded the highest (p< 0.05) values for ry matter degradability of 65.0% at 48 h; organic matter digestibility of 45.86%; the predicted dry matter intake of 4.0% body weight and the lowest (p<0.05) rate of digestion (0.01 ml/h). It was concluded that, all the browse species would provide good nutrition for browsing ruminants, but of these four plants,S.nodiflora appeared to be the best browse species with the lowest potential for methane emission.
