The study aimed at the utilization of locally available feed resources for increasing growth performance and reducing enteric methane emissions from goats in Lao PDR. The specific objectives were following: to evaluate the of water spinach as a source of high soluble protein and biochar on methane production in an in vitro system with substrate of Bauhinia acuminata or Guazuma ulmifolia leaves; to evaluate the effect of water spinach as a source of high soluble protein and biochar on feed intake, digestibility, N retention, methane emission and growth performance of goats fed Bauhinia acuminata foliages plus molasses or dried cassava root chip as the basal diets; to examine the effect of replacing water spinach by cassava foliage and/or brewer’s grain on feed intake, digestibility, N retention and growth performance of goat fed Bauhinia acuminata plus dried cassava root chip as the basal diets; to compare the sweet or bitter of cassava leaves and biochar on gas production, methane content of the gas and methane ml/g DM digested in an in vitro incubation. |
