This is the first series of study and the first sciencetific information on improving the utilization of Bauhinia acuminata for goat production in Laos. The results presented in this dissertation indicate that: (1) Goats fed Bauhinia acuminata responded with improved diet digestibility, N retention and growth rate when the Bauhinia acuminata was supplemented with water spinach; (2) But an important negative effect was that the improvement in diet digestibility by supplementation with water spinach led to increases in methane production per unit diet DM digested; (3) Supplementing Bauhinia acuminata foliage with leaves from a bitter variety of cassava reduced the in vitro production of methane when compared with supplementation by leaves from a sweet variety of cassava; (4) Ensiled brewers’ grains fed as an additive (5% as DM) to a diet of Bauhinia acuminata improved the digestibility, N retention and growth rate of goats. The degree of improvement was greater when the Bauhinia acuminata was supplemented with cassava foliage instead of water spinach; (5) Biochar fed at 1% of a diet of Bauhinia acuminata and cassava foliage was as effective as brewers’ grains in improving the growth rate of the goats.
