Research Interest

• Suitable nutrient partitioning will be different according to the purpose of ruminant production (milk, lean meat, intramuscular fat), and its physiological stages (pregnancy, growth, milking). Manipulating the partition of nutrients content of ruminant feed is also one of strategy to mitigate methane emission from enteric fermentation.
• Current research activities are in two main areas
  • Mitigation research of methane emission from enteric fermentation
  • Establishment of country-specific emission factor in the areas of enteric fermentation
  • Development of feeding program for high quality beef production with high marbling
