Conventional feed sources are an indispensible part in livestock feeding for Indian rural households. Though India possesses huge population of diverse livestock, but the productivity is low. The main constraint in livestock production is unavailability or fluctuating year round feed supply of quality feed. Therefore, for sustainable development of livestock sector, it is pertinent to look into all possibilities to overcome feed shortages. The inclusion of non-conventional feed resources (NCFR) could be a most viable option for bridging the gap between supply and demand for animal feeds, for reducing the competition between human and animals for food and for providing nutritional sufficiency to available feed sources. This would also be an effective way of diversification of traditional agriculture and biodiversity conservation. A variety of feeds from perennial crops, multipurpose trees and shrubs, weeds and agro-industrial byproducts are included in the category of NCFR. They are excellent source of nutrients which keep intestinal microflora active for digesting cellulosic biomasses.
However, some of them are low in nutritive quality and contain high concentrations of aversive factors which reduce the nutrient utilization and causes discontinuation of various metabolic processes. An array of processing and feeding methods has been developed to overcome the negative effects of the anti-nutrients from NCFR. The present review emphasizes the integration of NCFR in livestock feeding for achieving improved livestock productivity and the sustenance of rural livelihoods.
