If certain guidelines are followed when feeding sweetpotatoes to livestock it is possible to minimize health hazards. Careful herd management and the recognition of specific biomarkers such as excessive dental deterioration could aid in the early identification of feed problems. Where these tubers are produced locally in abundance there can be an economic and environmental incentive to divert waste sweetpotato by-products toward livestock feed. The feeding of culled sweetpotatoes and processed sweetpotato waste by-products can have three major benefits. First, expensive disposal costs are reduced. Second, negative environmental impacts from landfill dumping and crop spreading are limited. Third, the culled sweetpotatoes and SPCW offer an inexpensive and nutritious alternative feed ration for livestock that may increase economic returns.
如果在给牲畜喂食红薯时遵循某些指导方针，就有可能将健康风险降至最低。谨慎的畜群管理以及对特定生物标志物（如牙齿过度磨损）的识别有助于早期发现饲料问题。在当地大量生产这些块茎的地方，将废弃红薯副产品转作牲畜饲料具有经济和环境方面的激励因素。喂食淘汰红薯和加工后的红薯废料副产品有三大好处。首先，降低了昂贵的处置成本。其次，限制了垃圾填埋场倾倒和作物播撒对环境的负面影响。第三，淘汰红薯和红薯加工废料为牲畜提供了一种廉价且营养丰富的替代饲料，可能会增加经济回报。
