This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient utilization of feed protein by cattle, because of its impact on economics and the environment, is a major concern for animal nutritionists and producers. Ruminants play an important role in food production (milk and meat) and are major sources of protein for human livelihoods. Two experiments were conducted to assess the value of guanidinoacetic acid (GAA) with or without methionine (Met) on nitrogen retention, methionine flux, and methylation reactions in cattle. As well, a study was conducted to investigate the effectiveness of 2 ruminally protected methionine sources for lactating dairy cows. Another study evaluated effects of abomasal infusions of casein on dairy cattle production. The first experiment examined the effect of abomasal infusions of GAA (0, 10, 20, 30, or 40 g/d GAA) combined with either 0 or 12 g/d of methionine on creatine synthesis and plasma homocysteine concentrations in 6 ruminally cannulated Holstein heifers (520 kg initial body weight). This study demonstrated that plasma creatine was increased by GAA supplementation. Plasma homocysteine was not affected by GAA supplementation when heifers received 12 g/d methionine, but it was increased when 30 or 40 g/d of GAA was supplemented without methionine (GAA-linear x Met, P = 0.003). This experiment demonstrated that post-ruminal GAA supplementation increased creatine supply to cattle and spares arginine utilization. In the second study, effects of GAA supplementation on nitrogen retention and methionine flux were evaluated in 7 ruminally cannulated Holstein steers (161 kg initial body weight) limit-fed a soybean hull-based diet. Treatments were provided abomasally and included 0 or 6 g/d of L- methionine and 0, 7.5, and 15 g/d of GAA. Steers received continuous abomasal infusions of an essential amino acid mixture devoid of methionine to ensure that no amino acid besides methionine limited animal performance, and energy was supplied by ruminal infusion of volatile fatty acids and abomasal infusion of glucose. Whole body methionine flux was measured using continuous jugular infusions of 1-13C-L- methionine and methyl-2H3-L- methionine. Nitrogen retention was elevated by methionine supplementation (P

Download or read book Energy and Protein Metabolism and Nutrition written by Mario Luiz Chizzotti and published by Brill Wageningen Academic. This book was released on 2019 with total page 0 pages. 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 General Methods in Biomarker Research and their Applications written by Victor R. Preedy and published by Springer. This book was released on 2015-08-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease. The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics and so on. The chapters are written by national or international experts and specialists.
Download or read book Aquatic Animal Nutrition written by Christian E.W. Steinberg and published by Springer Nature. This book was released on 2022-01-03 with total page 1082 pages. Available in PDF, EPUB and Kindle. Book excerpt: As sequel to Aquatic Animal Nutrition – A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition – Organic Macro and Micro Nutrients addresses several gaps in nutritional research and practice. One major gap is the lack of common research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aquatic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel genetic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To increase public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.
