Pig-raising in urban areas has become important in meeting the growing pork demand. The main constraints to using sweet potato vines as pig feed are labour and storage. Regardless of how they are fed to the animals, the vines must first be chopped into small pieces, a daunting and time-consuming task, mainly undertaken by women. If the vines are fed fresh, the women must allocate time each day for this task, even during the busy field season. Silage offers a potential alternative and overcomes both main constraints.
