Cassava called Manihot esculenta, is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize. Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people. Cassava is one of the most drought-tolerant crops, capable of growing on marginal soils and Nigeria is the world's largest producer of cassava, while Thailand is the largest exporter of dried cassava. Cassava can be processed into various products such as garri,tapioca, cake,bread and flakes for human consumption,but the peels can be processed and fed to animals. Cassava peels,used to be an environmental nuisance,because farmers and processors just left heaps on the floor to decompose or they burn them because they did not know how to process or preserve the peels until intervention of CGIAR. CGIAR scientists developed a low-tech way of transforming wet cassava peels into high quality, safe and hygienic feed ingredients within eight hours, producing one tonne of high quality cassava peel (HQCP) mash from three tonnes of wet peels. The processing of the peels into feed has a high potential because Africa’s estimated 50 million tonnes of cassava peel waste per year could generate at least 15 million tonnes of HQCP, thus providing alternative animal feed that are cheap ,easily accessible and with a capacity of creating a $2 billion a year industry on the continent. The cassava peels can be fed to both ruminants,fish and monogastrics,making it an ideal feed source,locally produced to reduce cost and boost productivity. The processing of the peels depend on the target animals. The cassava peels processing is as follows; 1) peels must be clean and fresh. 2) sorted to remove tubers or big sized lumps/cuts. 3) pour the peels in a grater,and grate 3 times.4) put in sacks stacked on one another in an hydraulic press to dewater the peels. 5) 24hrs later the cassava peel cake is ready and can be fed to cattle, sheep,goat and pigs.
