Locally Produced Agricultural By-Products as Feed Sources for Pigs

Raw fiber concentrates, products with high content in cellulose, hemicellulose and lignin, are new sources of concentrates with high biological and functional value. Recent studies have demonstrated that raw fiber concentrated products have a positive influence on intestinal development, in health status of piglets and in sows. Agricultural by-products with high lignocellulose content are commonly used as supplementary feeds for animals and with their low or zero cost can also improve the economic efficiency of animal production. The materials that have been studied in this work currently are wasted or in best case are used as pellets fuel.
