Download or read book Cysteine in Broiler Poultry Nutrition written by Iyakutye Jacob Nte and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SAAs are limiting in the major poultry feed ingredients, ranking first and fifth in soya bean meal and maize, respectively. Feed ingredients rich in protein, in particular and other nutrients, enhance Energy supply and protein accretion. Modern commercial broilers have reduced maintenance needs and high amino acid requirements, and are more responsive to protein (amino acids) than energy. Cysteine is a semi-essential amino acid belonging to the SAAs. It plays essential roles in protein synthesis, structure and function, causing growth depressing effects in broiler chicks when there is methionine:cysteine imbalance. Genetically predetermined amino acid sequences in proteins are essential for production of adequate quantities of meat, milk and eggs. Therefore, ideal amino acid ratios which conform to the requirements of broilers should be utilized. In nutrition, amino acids are equivalent to proteins, hence the shift in focus from proteins to individual amino acids, expressed as ideal ratios to lysine. The SAAs are practically relevant and have critical nutritional roles in animal nutrition with over 90% production being used to fortify animal (particularly poultry) diets. A balance in the methionine:cysteine ratio is necessary to ensure efficient utilization of the SAAs for proper growth and development in broiler poultry.
Download or read book Amino Acids in Nutrition and Health written by Guoyao Wu and published by Springer Nature. This book was released on 2021-03-26 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amino acids (AAs) are not only building blocks of protein, but are also signalling molecules as well as regulators of gene expression and the protein phosphorylation cascade. Additionally, AAs are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological importance. For example, physiological concentrations of AA metabolites (e.g., nitric oxide, polyamines, glutathione, taurine, thyroid hormones, and serotonin) are required for cell functions. Growing evidence shows that humans and animals have dietary requirements for all proteinogenic AAs. Mammals, birds and fish also have species- and age-dependent needs for some AA-related substances. However, elevated levels of other products (e.g., ammonia, homocysteine, H2S, and asymmetric dimethylarginine) are pathogenic factors for neurological disorders, oxidative stress, and cardiovascular disease. Thus, optimal amounts of AAs and their ratios in diets and circulation are crucial for whole body homeostasis and health. Adequate provision of one or a mixture of functional AAs or metabolites may be beneficial for ameliorating health problems at various stages of the life cycle (e.g., fetal growth restriction, neonatal morbidity and mortality, weaning-associated intestinal dysfunction and wasting syndrome, obesity, diabetes, cardiovascular disease, the metabolic syndrome, and infertility). Dietary supplementation of these nutrients can also optimize the efficiency of metabolic transformations to enhance muscle growth, milk production, and athletic performance, while preventing excess fat deposition and reducing adiposity. Therefore, functional AAs hold great promise in improving the growth, health and well-being of individuals.

Download or read book Advances in Poultry Nutrition Research written by Amlan Kumar Patra and published by BoD – Books on Demand. This book was released on 2021-07-07 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the wide acceptance of poultry meat and eggs, poultry farming is the fastest growing global livestock industry. Nutrition plays a vital role in economic production and the maintenance of proper poultry health. Therefore, there is a great need to update balanced nutrient requirements for new breeds, utilize alternative feed resources, evaluate newer feed additives to optimize production while excluding antimicrobial feed additives and maintain overall health. The first section of this book contains six chapters that discuss the utilization of unconventional feeds, nanominerals to reduce mineral proportions in diets, and water intake affected by environmental temperature. The second section contains six chapters that describe proper nutritional management to improve gut health and immunity, the prevention of common diseases, and the amelioration of heat stress in poultry.

Download or read book The Role of Chromium in Animal Nutrition written by National Research Council and published by National Academies Press. This book was released on 1997-11-17 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American feed industry manufactures tons of dietary supplements and additives each year for inclusion in the diets of food-producing animals. Some scientists have suggested that chromium should be a key ingredient in nutritional supplements. Controversy exists, however, over whether chromium sources should be approved as feed additives and whether enough data exist to establish dietary requirements. Chromium use has been suggested to have positive impacts on farm profitability, and many animal health benefits have been attributed to chromium supplementation, including increased longevity; enhanced reproduction; decreased incidence of metabolic disorders, stress effects, and disease; reduced need for antibiotic usage; improved immune response; and lean carcass quality. This book addresses recent research on chromium in animal diets; metabolic interactions between chromium and other nutrients; assessments of form and species interactions; supplementation effects; bioavailability of chromium forms and sources; and effects of diet composition, stressors, and animal physiological status on chromium utilization. It also provides recommendations on the essentiality of dietary chromium in domestic animal species and guidelines for use of dietary chromium.
