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. Online journals follow a systematic pattern with a particular style which is universally followed to avoid confusion. All the information should be unbiased, readily proven and can be challenged in any kind of situation. Each and every fact should be made clear by providing proper evidence thereby encouraging true scholar and safeguarding copyrights. Following such stringent rules and evaluation can be costly, so publishers charge from the users who access the information, but, it will obstruct research as young researchers can afford it. Alternatively, fees can be charged from the researcher who has made the research and it can be free to the user who is interested in research thus, increasing the popularity and reputation to scholar and enhancing knowledge to user.
