ANIMAL PRODUCTION AND GRASSLAND DIVISION: Diagnosing and developing control measures for classical swine fever in the Mekong Delta region of Vietnam

摘要

Swine production developed dramatically in Vietnam in the 1990's (a 7% annual increase) and by 2000, the pig population in the region reached 20 million heads. One of the two major agricultural areas of Vietnam, the Mekong Delta region produced more than 2.9 million pigs in 2000, while making use of abundant rice by-products. A typical pigsty is found in the farm backyard; pigs are fed with rice bran and water spinach, and sewage from the pen is drained into adjacent fishponds or irrigation canals as nutrient-rich fertilizing material.
