Growth rate and feed conversion were improved, and emissions of methane reduced, when goats fed a basal diet of pigeon wood foliage (Trema orientalis) were supplemented with sun-dried cassava foliage (Manihot esculenta, Crantz) or water spinach (Ipomoea aquatica)

The treatments applied to 12 local goats housed in individual pens were three feeding systems: pigeon wood foliage alone or supplemented with sun-dried cassava foliage or water spinach (20% of basal diet DM). Supplementation resulted in higher feed intake and growth rates, and better feed conversion, with best results for cassava foliage. The proportion of methane in eructed gas was reduced when pigeon wood foliage was supplemented with sun-dried cassava foliage or fresh water spinach, with lower values for cassava foliage than for water spinach.
