Book excerpt: Amino acids (AA) are essential components of diets but accurate determination of AA requirements in farm animals is a challenge. Requirements for AA in pigs can be influenced by several factors, including genetics, health, age, and, as recently shown, also individual variability. In conventional group-phase feeding (GPF) systems, large groups of pigs receive the same feed during extended periods and most pigs receive more nutrients than required to express their growth potential with potential detrimental effects on the environment through increased nitrogen excretion, and on production costs. In individual precision feeding (IPF) systems, pigs are fed diets tailored daily to their individual nutrient requirements. In light of this, it is necessary to distinguish the AA requirements of a population from those of individuals. Optimal essential AA ratios have been established for pigs in conventional GPF systems, but these optimal AA ratios might differ for pigs in IPF systems. The main research objective was to compare the ideal protein profile in pigs using the optimal threonine-to-lysine (Thr:Lys) ratio between conventional GPF and IPF systems. Based on a dose-response approach with five levels Thr:Lys ratios offered to growing pigs in a GPF or IPF system, it was possible to confirm the initial hypothesis that optimal AA ratios differ between feeding systems. Carcass chemical composition and AA concentration was likewise affected by the Thr:Lys ratio, and the magnitude and type of response depended on the feeding system. In a second dose-response study with similar Thr:Lys ratios offered to late finishing pigs, requirements were larger than to those previously observed for growing pigs, suggesting that AA requirements for protein deposition is age dependent. These two studies suggest that individual pigs can modulate their growth and body composition according to the level of AA intake and can respond differently to same amount of ingested AA. These studies further highlighted the weakness of using an ideal protein profile by considering fixed requirements for AA due the assumed constant AA carcass composition. Accurate estimation of AA requirements for pigs in an IPF system seems to be mainly limited by the use of fixed AA ratios as pigs have different AA requirements. Finally, a novel approach to the dose-response approach based on a central composite design with a factorial design aiming at independently estimating real-time requirements for Lys and Thr in individual pigs was proposed. A non-unique response of protein deposition to various Thr and Lys combinations was observed due to the differences in AA requirements among individual pigs. This insight on variability among individual pigs is useful to fine-tune the precision feeding system by estimating AA requirements more accurately, feeding pigs according to their individual requirements, and, ultimately, reduce waste of nutrients in pigs with lower protein deposition. The results presented in this thesis support the idea that changes in body composition in pigs are induced by changes in dietary AA levels. Therefore, growth may be modulated to the optimal body composition desired by the consumer. This thesis proposes a change of perspective in animal nutrition, where AA may be seen as a trigger for animal metabolic response with dynamic and distinctive AA requirements in individual animals.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The last book on the lactating sow was published over 15 years ago. This new book brings us up to date in current knowledge on the gestating and lactating sow. It covers new and important topics such as conditioning of gilts for optimal reproductive performance, feeding high fibre diets to gestating sows and providing various fat sources in gestation and lactation. It also describes the several key success factors to group-housing systems in gestation, which is a must due to the current move towards group-housing. The new concept of transition feeding for sows is discussed, as well as the factors involved in mammary development of gilts and sows, both of which are instrumental for maximum colostrum and/or milk yields. The impact of the human-animal interactions on sow welfare and performance is discussed with focus on new handling practices that could be developed to overbalance the negative interactions inherent to pig management systems. Updates on must-have topics, such as amino acid and energy requirements of sows, colostrum and milk yield and composition, and sow health are also provided. The subjects covered in this book will assist animal scientists, nutritionists, veterinarians and swine producers in learning the most recent information on relevant and current topics affecting sow production, and in knowing which areas are in need of further research efforts.
