This paper details a field survey conducted in three dairy cattle production centres (Malang, Kediri, and Blitar) of East Java on the use of cassava pulp as feed. The authors found a very high usage of cassava pulp as additional feed for dairy cows, particularly in the dry season when a large supply of the pulp was available. The report identifies a number of advantages identified by farmers of feeding cassava pulp to dairy cattle, including improving palatability of concentrate feed and increasing milk yield. It also notes that incorporating cassava pulp into feed does slightly decrease milk fat content. The authors discuss their findings with respect to the use of the pulp, regardless of its quality or hydrogen cyanide content. The report outlines and briefly discusses the cassava pulp supply chain and price differences between wet and dry pulp. The paper is reasonably well laid out and easy to read, however the conclusion reached by the author is somewhat simplistic - that cassava has the potential to be an important feedstuff, and the most limiting factor is supply. It assumes that increasing the supply of cassava will result in increased used of the by-products by cattle farmers to supplement feed.
