Paper Title
Major Non-Conventional Feed Resources of Livestock
  Abadi Nigus Areaya

This paper aims to review the major non-conventional feed resources of livestock. Limited feed supply and poor quality of the available feeds are the major constraints for optimal livestock productivity in tropical and sub-tropical countries. Non-conventional feed resources (NCFR) generally refer to all those feeds that have not been traditionally used for feeding livestock and are not commercially used in the production of livestock feeds. Some of the potentially available NCFR are rubber seed cake, Sal seed meal, tapioca waste, tea waste, babul seeds, slaughter house byproducts, mango seed kernels, nizger seed cake, karanj cake, guar meal, Prosopis juliflora pods and cassava leaf meal, Sea buckthorn leaves, cake and pomace, and animal organic wastes (bovine and poultry excreta) etc. Many of these feed materials are low in energy, protein, minerals and contain high amounts of lignin, silica and other nutritionally incriminating substances. One major constraint in the use of non-conventional feedstuffs is the anti-nutritional factors contained in them. Anti-nutritional factors may be defined as the chemical constituent of a feedstuff, which interferes in the normal digestion, absorption and metabolism of feeds, some of which may have deleterious effects on the animal’s digestive system. Some inherent chemical constituents present in different kinds of feedstuffs interfere in the optimum utilization of nutrients and some are also toxic in high concentrations. Although anti-nutritional factors are present in many conventional feeds, these are more common in most of the non-conventional feeds. These anti-nutritional factors need to be removed or inactivated by various procedures before the use of the ingredients in the diet.
