Book Synopsis Optimisation de l'usage des coproduits dans l'alimentation des porcs en croissance by : Laurie Dickner-Ouellet
Download or read book Optimisation de l'usage des coproduits dans l'alimentation des porcs en croissance written by Laurie Dickner-Ouellet and published by . This book was released on 2018 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'augmentation du coût des ingrédients de base des aliments pour porcs a permis à certains ingrédients alternatifs de se tailler une place sur les marchés nord-américains de l'alimentation animale. En effet, leur utilisation judicieuse en production porcine peut représenter un atout économique important. Toutefois, l'usage d'ingrédients alternatifs est limité dans les aliments pour porcs, notamment à cause leur effet parfois négatif sur la qualité de la carcasse ainsi que de leur teneur élevée en fibres alimentaires, peu valorisées par les monogastriques. Ce projet avait comme objectif de mieux comprendre l'impact de l'usage des ingrédients alternatifs disponibles dans l'Est du Canada afin de diminuer les coûts d'alimentation, sans modifier les performances de croissance chez le porc. Plus précisément, le projet visait à évaluer l'impact de différents types de fibres (solubles et insolubles) et de la supplémentation en xylanase, une enzyme exogène, sur la digestibilité iléale apparente des composants nutritionnels ainsi que sur les performances de croissance et la composition corporelle chez le porc en croissance-finition. Pour ce faire, deux expérimentations ont été réalisées. La première était un essai de digestibilité réalisé à l'aide de porcs canulés chez lesquels la digestibilité iléale apparente a été mesurée pour différents aliments variant en leur teneur et leur type de fibres, et selon l'addition ou non de xylanase. La seconde expérimentation consistait en un essai de croissance chez le porc en finition afin de mesurer ces mêmes traitements sur les performances de croissance, la composition corporelle et la qualité du gras. Les résultats obtenus montrent que les niveaux élevés de fibres alimentaires utilisés n'ont pas eu d'effets majeurs sur la digestibilité iléale apparente des nutriments et de l'énergie, sur la composition corporelle et sur les performances de croissance des animaux. De plus, l'ajout de xylanase dans les aliments a eu peu d'effets sur les critères mesurés.
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 The Value of Fibre by : G. González-Ortiz
Download or read book The Value of Fibre written by G. González-Ortiz 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: Dietary fibre has been associated with impaired nutrient utilisation and reduced animal performance. A minimum amount of dietary fibre is required to maintain normal physiological functions in the gastrointestinal tract. This book reviews the latest advances in the understanding of dietary fibre for animal nutrition. Fibre clearly has more value than was once thought. This book attempts to define not only the analytical constraints but also the advances in understanding its role in intestinal development and health in both swine and poultry. It identifies how we can exploit fibre to the advantage of the host. Stimulating the gastrointestinal microbiota (often referred to as the second brain) to digest more fibre creates a more favourable environment for intestinal health. This outcome is especially important in antibiotic free diets. The type of fibre employed, the use of exogenous enzymes and the interaction between them, the gastrointestinal microbiota and the host will be covered in detail throughout the chapters. This book discusses the practical application of this research and has been written for all animal scientists, nutritionists, feed producers and anyone interested in exploring new developments in the understanding of dietary fibre.

Book Synopsis Food Chemistry Research Developments by : Konstantinos N. Papadopoulos
Download or read book Food Chemistry Research Developments written by Konstantinos N. Papadopoulos and published by Nova Publishers. This book was released on 2008 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.

Book Synopsis Local Food Systems; Concepts, Impacts, and Issues by : Steve Martinez
Download or read book Local Food Systems; Concepts, Impacts, and Issues written by Steve Martinez and published by DIANE Publishing. This book was released on 2010-11 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive overview of local food systems explores alternative definitions of local food, estimates market size and reach, describes the characteristics of local consumers and producers, and examines early indications of the economic and health impacts of local food systems. Defining ¿local¿ based on marketing arrangements, such as farmers selling directly to consumers at regional farmers¿ markets or to schools, is well recognized. Statistics suggest that local food markets account for a small, but growing, share of U.S. agricultural production. For smaller farms, direct marketing to consumers accounts for a higher percentage of their sales than for larger farms. Charts and tables.
Book Synopsis Morphological Plant Modeling: Unleashing Geometric and Topological Potential within the Plant Sciences by : Alexander Bucksch
Download or read book Morphological Plant Modeling: Unleashing Geometric and Topological Potential within the Plant Sciences written by Alexander Bucksch and published by Frontiers Media SA. This book was released on 2017-10-13 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increasing population faces the growing demand for agricultural products and accurate global climate models that account for individual plant morphologies to predict favorable human habitat. Both demands are rooted in an improved understanding of the mechanistic origins of plant development. Such understanding requires geometric and topological descriptors to characterize the phenotype of plants and its link to genotypes. However, the current plant phenotyping framework relies on simple length and diameter measurements, which fail to capture the exquisite architecture of plants. The Research Topic “Morphological Plant Modeling: Unleashing Geometric and Topological Potential within the Plant Sciences” is the result of a workshop held at National Institute for Mathematical and Biological Synthesis (NIMBioS) in Knoxville, Tennessee. From 2.-4. September 2015 over 40 scientists from mathematics, computer science, engineering, physics and biology came together to set new frontiers in combining plant phenotyping with recent results from shape theory at the interface of geometry and topology. In doing so, the Research Topic synthesizes the views from multiple disciplines to reveal the potential of new mathematical concepts to analyze and quantify the relationship between morphological plant features. As such, the Research Topic bundles examples of new mathematical techniques including persistent homology, graph-theory, and shape statistics to tackle questions in crop breeding, developmental biology, and vegetation modeling. The challenge to model plant morphology under field conditions is a central theme of the included papers to address the problems of climate change and food security, that require the integration of plant biology and mathematics from geometry and topology research applied to imaging and simulation techniques. The introductory white paper written by the workshop participants identifies future directions in research, education and policy making to integrate biological and mathematical approaches and to strengthen research at the interface of both disciplines.
