Meeting livestock nutritional requirements is extremely important in maintaining acceptable performance of neonatal, growing, finishing and breeding animals. From a practical standpoint, an optimal nutritional program should ensure adequate intakes of amino acids (both traditionally classified essential and nonessential), carbohydrates, fatty acids, minerals, and vitamins by animals through a supplementation program that corrects deficiencies in basal diets (e.g., corn- and soybean meal-based diets for swine; milk replacers for calves and lambs; and available forage for ruminants). Additionally, dietary supplementation with certain nutrients (e.g., arginine, glutamine, zinc, and conjugated linoleic acid) can regulate gene expression and key metabolic pathways to improve fertility, pregnancy outcome, immune function, neonatal survival and growth, feed efficiency, and meat quality. Overall, the proper balance of protein, energy, vitamins and all nutritionally important minerals in diets is needed to make a successful nutrition program that is both productive and economical. Both fundamental and applied research is required to meet this goal. Journals are the major source of knowledge for young and aspiring generations who are keen in pursuing their careers in science. This system provides easy access to networks of scientific journals. Authors who contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholars explore these works extensively. This process assures considerable impact factor for the journal and good reputation to the authors that add value to their Academic Performance Index (API) Score. Because of the free access open access journals impact factors are improving.
