These include poi fresh or fermented paste, canned, and canned-acidified , flour, cereal base, beverage powders, chips, sun-dried slices, grits, and drum-dried flakes. In addition to these results, other studies on the feeding value of taro silage showed that the fermentation characteristics were comparable with other silage, and that taro silage could meet much of the feed needs for brood sows with no reproductive problems and good litter performance Carpenter and Steinke, In many tropical developing countries, edible aroids and other indigenous non-conventional feedstuffs can help to lower feed energy costs and save some quantity of cereals for human food. For best results, it is important to ensure that the moisture content of the coir is damp and not wet as the latter would facilitate the decay of corms. Often, imported feeds are too expensive for farmers in these subsistence environments. Therefore, corm flour does not constitute a major health hazard in this regard, making it suitable for human consumption. The nitrogen-free extract NFE was estimated by difference.
