Given the importance of pork in the Vietnamese diet, this trend is of concern to the Government of Vietnam. Some policymakers think that the main problem is the inefficiency of small household suppliers of pigs and believe the answer to the problem is to expand production by larger-sized commercial producers. However, at this stage in Vietnam’s development, small household producers still make an important contribution to Vietnam’s supply of pork, accounting for at least 70% of supply. In many cases, their costs of production are lower than can be achieved by larger commercial producers because they utilize inputs that otherwise may be unused or under-utilized. They are also much less reliant on imported pig food than are large commercial producers.
In the current situation, ways should be explored to reduce the cost of production for both household and non-household producers. Attention should be given, for example, to increasing the supply and reducing the cost of domestically produced pig food and utilizing available supplies more efficiently.
