Development and Dissemination:
Improving Pig Feed Systems in
Sweetpotato-pig production is an important system that generates income, utilizes the unmarketable and undesirable crops, and provides manure for soil fertility maintenance. This system is practiced by many households in sweetpotato-producing region in the developing world. Considering the importance of this system to rural household economy, improvements in this system could have widespread impact.
With the aim of generating income through improved sweetpotato-pig feed system in Vietnam, the International Potato Center’s (CIP) Sweetpotato Postharvest Project and the Users’ Perspectives with Agricultural Research and Development (UPWARD), collaborated with Vietnamese research institutes in a diagnosisintervention-dissemination process of situation analysis, participatory technology development (PTD), scaling up and monitoring and evaluation (M&E) over a six year period (1997–2002).

The situation analysis involved a series of production surveys conducted between 1997 and 1999 and a large pig supply-market chain identification survey. PTD, on the other hand, included on-farm technical interventions such as sweetpotato
