Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods in Protein Nutrition and Metabolism grew out of a series of seminars (Modern Views in Nutrition) held in 1989 at Iowa State University. These seminars and this book were financed primarily through the Wise and Helen Burroughs Lectureship endowment generously established by the late Dr. Wise Burroughs and his wife Helen. This book comprises 12 chapters, and begins with a focus on amino acid analysis in food and physiological samples. Succeeding chapters go on to discuss concepts and techniques on nitrogen balance; determination of the amino acid requirements of animals; and novel methods for determining protein and amino acid digestibilities in feedstuffs. Other chapters cover measurement of protein digestion in ruminants; evaluation of protein status in humans; surgical models to measure organ amino acid metabolism in vivo; and measurement of whole-body protein content in vivo. The remaining chapters discuss estimation of protein synthesis and proteolysis in vitro; isotopic estimation of protein synthesis and proteolysis in vivo; n-glycine as a tracer to study protein metabolism in vivo; and mathematical models of protein metabolism. This book will be of interest to practitioners in the fields of human nutrition and medicine.

Download or read book Effect of Reducing Dietary Protein Level and Adding Amino Acids on Performance, Carcass Characteristics, and Nitrogen Excretion of Finishing Pigs written by Haijun Liu and published by . This book was released on 2000 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of eight experiments utilizing 572 finishing pigs were conducted to evaluate the effect of reducing dietary protein level and adding amino acids on pig performance, carcass characteristics, and N excretion. The valine requirement of early-finishing (50 to 80 kg) barrows and the effect of adding isoleucine (Ile) and valine (Val) in amino acids fortified low-protein diets on finishing pig performance were also evaluated. In the first experiment (Exp. 1 of Chapter II), it was determined that the CP level in the diet for early-finishing (50 to 80 kg) gilts can be reduced up to four percentage units by adding Lys, Thr, Trp, and Met, with no detrimental effect on pig performance or carcass characteristics. The second study (Exp. 2 of Chapter II) indicates that Ile and/or Val may be limiting in a four-percentage-unit-protein-reduced diet for late-finishing (80 to 120 kg) gilts. The third experiment (Exp. 1 of Chapter III) indicates that the true digestible Lys requirement of early-finishing PIC barrows is not higher than 0.70%. In the fourth experiment (Exp. 2 of Chapter III), it was demonstrated that dietary protein level for early-finishing PIC barrows can be reduced up to five percentage units by adding Lys, Thr, Trp, Met, and Ile, with no detrimental effect on pig performance or carcass characteristics. Valine was not limiting in a 10.49% CP diet for early-finishing PIC barrows with ADFI of 3.1 kg/d, and the true digestible Val requirement of early-finishing PIC barrows gaining 1.0 kg/d, was not greater than 11.4 g/d. In the fifth experiment (Exp. 3 of Chapter III), we found that decreasing dietary protein level by 4.81 percentage units and adding amino acids to the diet reduced N excretion of early-finishing barrows by 40.6%. In the sixth experiment (Exp. 4 of Chapter III), it was determined that the dietary protein level for early-finishing barrows can be reduced up to four percentage units by adding Lys, Thr, Trp, and Met, with no detrimental effects on pig performance or carcass characteristics, and reducing dietary protein level by four percentage units can reduce N excretion by 38.4%. In the seventh experiment (Exp. 1 of Chapter IV), it was determined that late-finishing barrows fed an amino acid (Lys, Thr, Trp, Met, Ile, and Val) fortified corn diet (7.92% CP) have similar performance and carcass characteristics as pigs fed a corn-soybean meal control 12.50% CP diet. Deleting Ile or Val in an amino acids fortified corn diet may decrease pig performance. In the eighth experiment (Exp. 2 of Chapter IV), it was determined that late-finishing gilts fed an amino acid (Lys, Thr, Trp, Met, Ile, and Val) fortified corn diet (9.55% CP) have similar performance and carcass characteristics as pigs fed a corn-soybean meal control 15.17% CP diet. Decreasing dietary CP level from 15.17 to 9.55% decreases N excretion of late-finishing pigs by 48.28%. Deleting Ile or Val in an amino acid fortified corn diet may decrease pig performance. In summary, finishing pigs fed a low protein diet properly fortified with crystalline amino acids can have similar performance and carcass characteristics as pig fed typical protein level corn-soybean meal control diets, and N excretion will be greatly reduced.

Download or read book Effects of Amino Acid Inclusion, Oil Source Or Mineral Supplementation of Swine Diets on Finishing Or Nursery Pig Performance written by Kyle Edward Jordan and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 6 experiments, a total of 1,802 pigs were used to determine: 1) effects of increasing crystalline amino acids in sorghum- or corn-based diets on nursery or finishing pig growth performance; 2) effects of different Zn sources on nursery pig performance; and 3) effects of different corn oil sources on nursery pig performance. In the first set of experiments, corn or sorghum-based diets were supplemented with increasing levels of synthetic amino acids up to the 5[superscript]th limiting amino acid. For nursery pigs, there were no main or interactive effects (P>0.05) of grain source or added amino acids which suggests that balancing up to the fifth limiting amino acid is possible in both sorghum- and corn-based diets with the use of crystalline amino acids without detrimental effects on nursery pig growth performance. For finishing pigs, balancing to the 5[superscript]th limiting AA using NRC (2012) suggested amino acid ratios in corn- or sorghum-based diets resulted in decreased ADG and G:F and pigs fed corn-based diets had greater G:F and IV than those fed sorghum. The second set of studies compared two new zinc sources to a diet containing pharmacological levels of ZnO on nursery pig growth performance. These studies demonstrated that increasing Zn up to 3,000 ppm Zn increased ADG and ADFI. Lower levels of the new zinc sources did not elicit similar growth performance as the high level of ZnO. The third set of studies compared increasing levels of different sources of corn oil to diets containing soy oil. In the first study, an oil source × level interaction was observed (P

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.

This book was released on 2017-05-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, the concept of standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) has been used in diet formulation for pigs. However, there is limited data on the nutritional composition and SID of CP and AA in home-grown European soybean and rapeseed products. For full-fat soybeans (FFSB), the presence of heat-labile trypsin inhibitors may cause problems in protein digestion of pigs. Therefore, the optimization of heat treatment for FFSB is a need to reduce trypsin inhibitor activity for improving SID of CP and AA. However, excessive heat treatment may have a negative effect on protein digestion. Furthermore, reducing dietary protein levels in combination with the supplementation of Bacillus spp. may reduce feed costs and improve pigs’ gut health. As a result of the present study, home-grown European soybean and rapeseed products can be considered as a suitable alternative to imported soybean products for pigs raised in organic and conventional farming systems. Wet heating at 100°C for 16 min, together with autoclaving at 110°C from 15 to 45 min reflects optimal heat treatment for FFSB resulting in greater SID of CP and AA with lower destruction of AA. Reducing the dietary CP level is an alternative strategy to improve SID of some AA, thereby decreasing feed cost and nitrogen excretion. The supplementation of Bacillus spp. promoted gene copy numbers of Roseburia spp., which may be beneficial due to ascribed health promoting properties of this butyrate producer.

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two 35-d experiments were conducted to investigate the effect of reducing crude protein by 2.5% and diet complexity with amino acid supplementation on performance and feed cost during the nursery phase. In Exp. 1 and 2, 32 PIC barrows (initial wt. = 7.28 ± 0.44 and 6.89 ± 0.77 kg, respectively) were weaned at 21 d and allotted to one of four dietary treatments in a completely randomized design (RCD) with four replicate pens per treatment with two pigs/pen. The four diets were: 1) corn-soybean meal based diet; 2) diet 1 with inclusion of fishmeal (FM) and spray-dried plasma (SDP) in Exp. 1 or soy protein concentrate (SPC) and spray-dried blood cells (SDBC) in Exp. 2; 3) low crude-protein diet (LCP) with 2.5% reduction; 4) LCP containing FM and SDP in Exp. 1 or SPC and SDBC in Exp. 2. In order to reduce CP by 2.5%, diets were supplemented with synthetic lysine, methionine, threonine and tryptophan (Trp) in Exp. 1 and in Exp. 2, LCP diets were additionally fortified with synthetic valine (Val) and isoleucine (Ile). Blood samples were collected on d 14, 21, 28 and 35 for determining plasma urea N (PUN). Growth performance was determined weekly. Overall in Exp. 1, pigs fed corn-soybean meal based diet containing higher CP had greater ADG (P = 0.001) than pigs fed LCP diet (0.60 vs. 0.52 kg/d, respectively) and final BW (25.28 vs. 22.95 kg, respectively) (P = 0.002). Pigs fed diets containing FM and SDP had higher final BW when compared to pigs fed less complex diets (24.87 vs. 23.35 kg, respectively) (P = 0.034). These data suggest that Val and Ile become the next limiting amino acids in LCP nursery diets. In Exp. 2, there was no effect on overall ADG and final BW. However, pigs fed HCP diets had decreased ADFI (P = 0.009) when compared to pigs fed LCP diets (0.92 vs. 1.01 kg/d, respectively). Meanwhile, pigs fed diets containing SDBC and SPC had decreased ADFI (P = 0.019) compared to pigs fed noncomplex diets (0.93 vs. 1.00 kg/d, respectively). Overall in Exp. 1 and 2, pigs fed LCP diets had lower PUN concentration (P
