Available in PDF, EPUB and Kindle. Book excerpt: Amino acid flow from the rumen was quantified and key aspects of rumen fermentation were evaluated in lactating dairy cattle. Rumen bacteria and protozoa were analyzed for amino acid (AA) composition and digestibility, and values were incorporated into the Cornell Net Carbohydrate and Protein System (CNCPS). Two in vivo studies were performed to evaluate the effects of a commercial fermentation byproduct on nutrient digestion, microbial growth, omasal flow of nutrients, and milk production in lactating dairy cattle. The objectives of the first portion of the first study (Chapter 2) was to evaluate nutrient digestion in the rumen and total tract, along with omasal flows of N. Inclusion of fermentation byproduct decreased dietary N degradation in the rumen, with no detrimental effects on microbial N flows. The second part of the experiment (Chapter 3) involved measurment of microbial growth and turnover, partitioning of protozoa and bacterial N, and determination of omasal AA flow. Cows fed the fermentation byproduct had increased flows of non-microbial AA at the omasal canal. Comparison of the observed results against model predicted values indicated that the rumen sub-model of CNCPS v.7 was able to provide accurate estimations of total microbial N. The second trial (Chapter 4) was performed to evaluate the effects of the fermentation byproduct on milk production in groups of lactating cows. Cows fed fermentation byproduct had increased energy-corrected milk yield and protein yield compared with cows fed regular and rumen protected soybean meal. In Chapter 5, two methods not previously applied to microbial samples were used to characterize the AA profile and digestibility of bacterial and protozoal protein. The values obtained, along with other updates to protozoal growth and turnover parameters from Chapter 3 were incorporated into the CNCPS. A comparison of model predicted vs. observed value from a larger literature dataset was used to evaluate improvements in the model's predictive capability. Overall, the use of omasal sampling, improved isolation of protozoa, and more accurate determination of post ruminal flows of digestible AA allowed for a more complete understanding of microbial protein synthesis and more accurate model predictions of post ruminal AA supply.

Download or read book Protein and Amino acid nutrition written by Anthony Albanese and published by Elsevier. This book was released on 2012-12-02 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein and Amino Acid Nutrition describes the state of knowledge concerning the nutrition of proteins and amino acids. Topics range from the effect of some therapeutic agents on protein and amino acid nutrition, to species and age differences in amino acid requirements; utilization of D-amino acids; effect of proteins and amino acids on the growth of adult tissue in vitro; and amino acid requirements of animals and young adults. This volume is organized into 16 chapters and begins with an overview of the nutritional implications of the metabolic interrelationships of amino acids. The next chapters discuss experiments that tested the differences in amino acid requirements due to the differences in age and in species among animals, the biochemical individuality of amino acid requirements, and the utilization of dietary proteins. This book explains the synthesis of tissue proteins in relation to the essential amino acids; the link between food energy and nitrogen metabolism; and the use of the repletion method to measure the nutritive value of proteins, protein hydrolyzates, and amino acid mixtures. The final chapter discusses the nutritional needs of the older age groups. This book is intended for scientists, students, and researchers interested in human and animal nutrition.

Available in PDF, EPUB and Kindle. Book excerpt: NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.

This book was released on 2013-06-05 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has a long history of coordinating isotope aided research projects for improving animal productivity in developing countries. These projects have focused on enhancing the efficiency of animal production through better use of locally available feed resources and those that do not compete with human food. As a part of these efforts, the Joint Division has been actively involved in developing and simplifying approaches for measuring microbial protein supply to ruminant livestock. The contribution of microbial protein in meeting the overall requirement for protein in ruminants is significant, but understanding the contribution of microbial protein to the nutrition of ruminant livestock has been hampered by the lack of simple and accurate methods for measuring microbial protein production in vivo. A Consultants’ Meeting was held in 1995 in Vienna to explore the feasibility of using nuclear and related techniques to develop and validate new approaches for measuring microbial protein supply in ruminant animals. Based on the available information, the consultants considered that the purine derivative excretion method, which is non-invasive and both simple to use and inexpensive compared with other available methods, had the potential for use in developing countries. However, development of models for various animal species and breeds and their validation were required before this technique could be advocated for use.
