Over the past 20 years increasing global growth and increased per capita income have led to significant changes in food production, consumption and trade for many countries. As incomes and urbanization increase, food consumption patterns exhibit increased demand for a more diversified diet increasing meat and dairy consumption, which leads to improved meat production systems and modern animal science-based feed rations. Greater demand for feed grains and oilseeds is provided by domestic production and through imports. This study analyzes the effects of Southeast Asia's changing food consumption patterns on agriculture production, consumption, and trade out to the year 2021. The impact of increasing consumption of poultry and pork and increased meat production and feed demand on domestic agricultural markets of Southeast Asia and international markets is assessed. Countries analyzed include Philippines, Indonesia, Vietnam, Thailand, and Malaysia. Results provide insights to potential higher global feed prices in the near future and constraints to expanding production. Global markets respond to higher feed prices through increased production and decreased demand.
