USE OF WASTE BARK AND SHAVINGS OF CASSAVA IN RUMINANT FEEDING

Abstract

Cassava (Manihot esculenta Crantz) is considered the most Brazilian of all economic plants and is one of the main food sources for millions, especially in developing countries, where it is grown in small areas with low technological level. Like any industrial process, the manufacture of derivatives of cassava also generates wastes such as bark, and bark and shavings. Cassava producers can take advantage of these residues as feed in the treatment of ruminant animals waste and lowering production costs. Thus, this study aimed to characterize waste bark, bark and cassava through bromatological analysis and guide for producers to use it correctly. The results showed that the bark, bark and cassava can provide energy for the cattle, however, serve as sources of protein and therefore should serve as a food supplement plus other sources of protein.
