Download or read book The gestating and lactating sow written by Chantal Farmer and published by BRILL. This book was released on 2023-09-04 with total page 452 pages. 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.

Download or read book The Effect of Dietary Amino Acid Balance on Nitrogen and Lysine Utilization in Lactating Sows written by Lee-Anne Huber and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Decreasing dietary crude protein (CP) concentration and increasing crystalline amino acid (CAA) supplementation, in order to maintain constant daily intakes of Lys and other key amino acids (AA), improves dietary AA balance. The effect of improved dietary AA balance on lactation performance, nitrogen (N) and AA utilization efficiency, and AA fates must be determined for precise lactating sow diet formulation and to meet specific production objectives. Performance, N balance, mammary biopsy, and isotope tracer studies were conducted to determine the effects of improving dietary AA balance on sow and litter lactation performance, N and Lys utilization efficiencies for milk production, mRNA abundance of mammary AA (Lys) transporters, and the partitioning of dietary AA between maternal and milk protein pools. Litter growth rates and milk protein production increased with improved AA balance, at the expense of maternal N retention, particularly in peak lactation. At identical Lys intakes, there was minimal improvement in Lys utilization efficiency for milk production with improved dietary AA balance, and there were no corresponding changes in the expression of mRNA for several Lys transporters within the mammary gland. Whole-body protein turnover and tissue-specific fractional rates of protein synthesis were not influenced by dietary AA balance. Feeding lactating sows reduced CP diets with increased inclusion of CAA, to improve AA balance and to meet the requirements of limiting AA, is a feasible way to improve the utilization of N and AA for milk protein production and decrease N losses to the environment, without negatively impacting sow and litter lactation performance. Amino acid and N requirements differ from those estimated by the NRC (2012) model and among genotypes and parity of sows. The utilization efficiencies of N and AA may change across a lactation period. All of these factors should be considered when planning future research and formulating lactating sow diets.

Download or read book Milk Proteins written by C.A. Barth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the state of knowledge and progress of research on food proteins, and in particular, milk proteins. Its basis is the Symposium on Milk Proteins that was held at the Federal Dairy Research Centre in Kiel, FRG, in June, 1988. Scien tists from around the world attended and addressed pure, as well as applied fields of protein research and technology. This book is divided into five sections, each adapted from the symposium's invited lectures, short communications, and poster presentations. New criteria for the "bio logical value" of dietary proteins and their relationships are considered according to: - Milk Proteins and Nitrogen Equilibrium - Milk Proteins and Ligands - Milk Proteins: Structural and Genetic Aspects - Milk Proteins: Technological and Functional Aspects - Milk Proteins and Clinical Nutrition Generally, different dietary proteins are classified according to their "biological value," i.e., their capacity to cause different retention of nitrogen in the body. But we think there are other intriguing leads worth studying that may help to identify which dietary proteins are best recommended for specific dietary situations or clini cal conditions. In addition, we have taken into consideration new fields such as attempts to determine the three-dimensional structure of proteins using two-dimensional NMR spectroscopy, and the application of genetic engineering to the lactating cell. In other words, we are on the way to the transgenic cow with customized milk constituents and composition.

Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.
Download or read book Evaluation of Dietary Protein Quality written by Alejandro Uribe-Peralta and published by . This book was released on 1978 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The use of a target protein against which the quality of other dietary proteins could be compared has been examined in rats. Milk, the natural food during the early life of mammals, was proposed as the target standard. The milk standard diet was compared with proteins of different origins, amino acid pattern, or lacking an essential amino acid. A chemical score based on rat's milk (CSM-R) was developed to evaluate the quality of the protein diets; it combined determination of a protein's most limiting amino acid with a capacity for ranking proteins by nutritional values. Diets were evaluated for protein efficiency ration, body weight gain, levels of amino acids and protein complementation. Results indicated that rat milk contains a proportion of amino acids which provides maximum protein utilization in growing rats, and may also protect the lactating mother. Other diets were usually inferior. The CSM-R score appeared to be a useful analytic tool in evaluating the quality of dietary proteins.
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 Impact of a Near Ideal Amino Acid Profile on the Efficiency of Nitrogen and Energy Utilization in Lactating Sows written by Sai Zhang and published by . This book was released on 2019 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving dietary amino acid (AA) and energy efficiency in lactating sows is a potential nutritional approach to mitigate impacts of swine production on the environment. In addition, greater metabolic rate during lactation renders sows prone to heat stress (HS), therefore strategies to lessen metabolic heat production will improve sow welfare in particular given the foreseeable increase in global warming. The main hypothesis of this dissertation was that feeding a reduced protein diet with near ideal AA profile (NIAA) and a leucine:lysine of 1.14 improves the dietary essential AA (EAA) and energy utilization efficiency for lactation, and reduces the metabolic heat associated with lactation, compared to feeding diets containing leucine:lysine of 1.63. To test the hypothesis, three diets were formulated iso-calorically (2,580 kcal/kg net energy), including 1) control diet with a 1.63 leucine:lysine (CON; 18.75% CP), 2) reduced CP diet with 1.14 leucine:lysine referred to as optimal (OPT; 13.75% CP) and formulated to contain a NIAA by supplementation with the limiting AA in their crystalline form to meet their minimum requirements (i.e., L-Lysine (Lys), L-Valine (Val), L-Threonine (Thr), L-Phenylalanine (Phe), DL-Methionine (Met), L-Isoleucine (Ile), L-Histidine (His), and L-Tryptophan (Trp); and 3) OPT diet with L-Leucine (Leu) supplementation to achieve CON Leu:Lys of 1.63 (OPTLEU; 14.25% CP). The overall objective was to determine the efficiency of individual EAA and energy for lactation in sows fed CON, OPT and OPTLEU, and quantify the metabolic heat production of lactating sows fed CON and OPT. Three studies were conducted to address the following aims: 1) to estimate maximal biological efficiency value (MBEV) of EAA in lactating sows fed CON, OPT and OPTLEU diets; 2) to estimate dietary energetic efficiency, energy partitioning and heat production in lactating sows fed CON, OPT and OPTLEU diets; and 3) to measure heat production in lactating sows fed CON and OPT diets and exposed to thermal neutral and HS environments. The first study showed that feeding OPT diet improved utilization efficiency of nitrogen (N) (79.1%), arginine (61.1%), His (78.3%), Ile (65.4%), Leu (75.1%), Met + Cys (78.2%), Phe (53.4%), Phe + Tyr (69.5%) and Trp (70.1%) and maximized the efficiency of Lys (63.2%), Met (67.9%), Thr (71.0%) and Val (57.0%) for milk production over a 21-day lactation period. Leucine reduced Met utilization but did not affect that of N and other EAA. The second experiment demonstrated that feeding OPT led to greater energy utilization for lactation due to less urinary energy and metabolic heat loss, and triggered dietary energy deposition into milk at the expense of maternal lipid mobilization. A Leu:Lys of 1.63 compared to 1.14 reduced dietary energy utilization for lactation by directing dietary energy away from the mammary gland and towards maternal pool, in part explaining the efficacy of a NIAA diet over CON. Sows fed OPT diet produced less metabolic heat and had lower body temperature when exposed to HS conditions compared to CON fed sows. In conclusion, feeding a diet with NIAA profile containing Leu:Lys of 1.14 improves dietary EAA and energy utilization efficiency for lactation, and reduces the metabolic heat associated with lactation compared to feeding a diet with Leu:Lys of 1.63 and meeting SID Lys requirement with feed ingredients as the sole source of Lys. This improvement is in part due to a lower dietary Leu:Lys. Feeding lactating sows with reduced CP diets with crystalline AA supplementation to attain NIAA profile is a feasible strategy to improve efficiency of N and energy utilization, and to mitigate the impacts of HS on lactating sows and of swine production on the environment.
