Feeding Concentrates

Pages : 190
Book Description
This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC 1993. It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best results in their particular situation. The benefits that arise from supplementary feeding include higher stocking rates, promotion of growth in heifers and young cows; better body condition score and increased lactation length when pasture is less available; improved pasture use; reduced cost per tonne of pasture eaten; flexibility to increase milk production when milk prices are high; and increased milk protein content when the energy content in pasture is low. This edition has thoroughly reviewed the issues and clearly documents the results of research particularly for grains supplementation. The summaries and recommendations in each chapter will be particularly helpful to dairy farmers in making best management decisions relating to concentrate feeding.

Book Description
Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
Rumenology

ISBN: 3319305336
Category : Science
Languages : en
Pages : 326
Book Description
The book combines information about the behaviour that allowed ruminants to survive and to evolve on Earth: the rumen. Furthermore, the reader will find aspects involving rumen anatomy, physiology, microbiology, fermentation, metabolism, manipulation, kinetics and modeling. Thus, the book was not only organized to help students involved in areas such as ruminant nutrition and ruminant production but collegians gathering material for teaching practices.
Effects of Dietary Potassium Carbonate and Fat Concentration in High Distiller Grain Diets Fed to Daily Cows

Book Description
Abstract: Distiller grains with solubles (DGS) can induce milk fat depression when included in dairy cow diets at greater than 20% DM. In vitro experiments have found that potassium (K) supplementation with potassium carbonate (K2CO3) decreased concentrations of biohydrogenation intermediates associated with milk fat depression (MFD), such as trans-10, cis-12 conjugated linoleic acid (CLA). These intermediates are often produced when diets are fed to cows with high concentrations of polyunsaturated fatty acids, like those in DGS. We hypothesized that there would be an interaction between level of K and level of fat. We hypothesized that adding K2CO3 to a high fat diet based on DGS would alleviate MFD. We also hypothesized that the addition of K2CO3 to a low fat diet based on DGS would have no effect on milk fat percent because these diets would not cause MFD. Sixteen Holstein cows averaging 157 days in milk were placed into 4 blocks; each block comprised a 4x4 Latin square with 21 d periods and a 2x2 factorial arrangement of treatments. The basal diet (no added K or fat) contained 27% DGS, 47% corn silage, 22% starch, 32% NDF, 4.2% long chain fatty acid, and 1.2% K (DM basis). Treatments were 0 or 2.3% added fat from corn oil (in high fat diets, DGS + corn gluten meal + corn oil = 27%) with 0 or 1% added K. Diets with added K had supplemental K in the form of K2CO3 from DCAD Plus® (Church & Dwight Co., Inc., Princeton, NJ). DCAD is a measure of the balance between cations and anions in the diet. DCAD over 20 meq/100 g DM improves performance for lactating cows, while low or negative DCAD benefit dry cows. Diets with added K had a DCAD of approximately 30, while diets without added K had a DCAD of 2. This low DCAD may have limited performance for cows fed diets without added K. Dry matter intake (DMI) decreased with added fat (21.0 vs. 22.5 kg/d; P

Book Description
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.
