This book was released on 2016-05-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Book Synopsis INRA feeding system for ruminants by : INRA
Download or read book INRA feeding system for ruminants written by INRA and published by BRILL. This book was released on 2023-11-27 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

Book Synopsis Metabolic Modifiers by : National Research Council
Download or read book Metabolic Modifiers written by National Research Council and published by National Academies. This book was released on 1994-02-01 with total page 94 pages. 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.

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.

The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.
Book Synopsis Nutrient Requirements and Utilization in Dairy Calves and Heifers by : Rodrigo Alfonso Molano Torres
Download or read book Nutrient Requirements and Utilization in Dairy Calves and Heifers written by Rodrigo Alfonso Molano Torres and published by . This book was released on 2020 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dairy cattle replacement programs should provide management and nutrition that best supports the evolving needs of the developing heifer during all phases of rearing. The work described in this dissertation had two main objectives, i) to evaluate the supplementation of nutrients that could be limiting for dairy calves transitioning from the preruminant to the ruminant state, and ii) to quantify energy and protein requirements of the growing dairy animal. The first objective was addressed with two feeding trials evaluating what are considered limiting nutrients during the weaning phase. The first study tested the inclusion of different forms of methionine (Met), one rumen-protected and two different analogs (HMBTa and HMBi), in the calf starter. Calves fed the starter with HMBi consumed more feed postweaning and where heavier at the end of the study, but overall calves seemed not to be limited by Met. The second feeding trial assessed the effect of the combined supplementation of B-vitamins and choline on measures of performance and vitamin adequacy, and results suggested that dairy calves could obtain sufficient B-vitamins and choline from the diet and rumen synthesis to support growth rates over 1 kg/d. For the second objective, a database was constructed by merging eight comparative slaughter studies conducted on growing dairy cattle. Using this data set as input, a first analysis explored different aspects concerning nutritional energetics and generated new maintenance requirements coefficients, estimates of efficiency of ME utilization and predictive equations for energy retention for preruminant and ruminant dairy cattle. A variable efficiency of ME utilization for growth calculated as a function of feeding level offered the best prediction ability of energy retention. Finally, a subsequent analysis generated a system of equations to predict net requirements, true supply and efficiencies of use of N and AA for young preruminant dairy calves. Requirements were defined based on the supply of N and AA per Mcal from total ME and carbohydrate ME. A combined variable efficiency allowed the best prediction of N and AA balance on a net basis. Together both models improved the understanding on nutrient partitioning and enhanced the accuracy to predict nutrient requirements and utilization in growing dairy cattle.
