文摘

Sweet potato roots provided high faecal digestible nutrients to grower pigs. Blended diets of boiled, ensiled or milled roots were of similar nutritional value. Retained nitrogen, growth and efficiency matched a wheat-based complete feed. Sweet potato roots may replace 70% of imported wheat in commercial pig feeds. Using stored root silage feed may be an advantage for smallholder pig production.
