The potential of Acacia polyacantha and Adansonia digitata for small ruminant feeding was evaluated through nutrient analysis, in vitro gas production and determination of organic matter digestibility, metabolizable energy, short chain fatty acids and methane production. Adansonia digitata seedcake and Acacia polyacantha leaves were analyzed along with Glycine max meal and Chloris gayana hay, which were common feed supplements to grazing goats at Bunda farm. Results from the study revealed that Acacia polyacantha leaf meal (212.3 g/kg DM) had higher CP than Chloris gayana hay (74.0 g/kg DM) but less than that of Adansonia digitata seedcake (310.5g/kg DM) which was lower than that of Glycine max (397.5 g/kg DM) (P < 0.05). Gas production (24 hours), OMD, ME and SCFA was similarly higher in Adansonia digitata and Glycine max. Least methane production was observed in Acacia polyacantha. It was concluded from the study that Adansonia digitata can be utilized for small ruminant production in arid and semi-arid parts of Malawi and that incorporation of right amounts of Acacia polyacantha in small ruminant diets could reduce enteric methane production and improve small ruminant productivity.
