Enriching the Nutritive Value of Cassava as Feed to Increase Ruminant Productivity
Energy and protein sources are of prime importance for ruminant feeding as they stimulate microorganisms in the rumen and enhance the productive functions of the animals. Cassava roots in the form of dry cassava chips or pellets, used as an energy source, and dried cassava leaves or cassava hay as a protein source, have been used successfully in ruminant rations, due to their high rumen degradable energy and by-pass protein, respectively. Using higher levels of cassava chips in the diets could enhance supplementation of urea as an non-protein nitrogen source. The use of cassava could provide year-round feed, resulting in high yields and good quality of meat and milk, and hence, contribute to a more lucrative dairy, beef cattle and buffalo production system, especially for small-holder farmers. Recent development by enriching protein in cassava chip based, yielding yeast fermented cassava chip protein (YEFECAP) up to 47.5% CP, used to replace soybean meal. Moreover, there are many available feed resources in the tropics which can potentially be used in ruminant feeding, particularly the development of food-feed-systems (FFS). A very practical FFS system is the intercropping of cassava with leguminous crops such as Phaseolus calcaratus, Vigna unguiculata etc., which resulted in improved soil fertility while providing food for humans and feed for livestock on a year-round basis.

More about this publication?
- Journal of Nutritional Ecology and Food Research is an international journal which publishes peer-reviewed articles on food production and consumption, with regard to health, environment, society and economy. The scope is thus broad, articles being focused on significant novel research in human and animal nutrition, food science and technology, food marketing and transportation. In addition, articles on food and identity, agriculture and sustainability, are also welcome. The journal only publishes novel, high quality review papers, original research papers, short communications, concerning all aspects of food and nutrition. It is journal policy to publish special issues on topical and emergent subjects of nutrition and food research or related areas.
