SAN FRANCISCO, US Vietnam animal feed market size is expected to reach US$10.55 billion by 2022. The market demand was 15,829 kilotonnes in 2014 and is expected to grow at a compound annual growth rate of 6.4 percent from 2015 to 2022, according to Grand View Research Incorporated. Shift in trends towards consumption of poultry and cattle meat is expected to remain a key driving factor for the Vietnamese animal feed market. Historically, domestic consumers depended largely on pork meat to meet the daily nutritional requirements, however, the increasing per capita disposable income level has led to changes in meat intake. Poultry was the leading livestock and accounted for over 39 percent of total volume in 2014. Incidences of disease outbreaks such as bird flu, fowl pox and avian influenza have driven demand for improved quality in poultry feed products. Incorporation of various immune boosting feed additives is also expected to drive its growth. Increasing investments particularly in research and development are expected to drive production sustainability over the forecast period. Fodder was the leading product segment and accounted for over 85 percent of the total volume in 2014. Industrialisation of livestock breeding has led to significant change in animal feed patterns, which were predominantly based on grazing and plant feed in pastoral regions. This factor is expected to drive fodder growth over the forecast period. Fodder is also expected to witness the highest gain in its market size over the forecast period
