Download or read book The gestating and lactating sow written by Chantal Farmer and published by BRILL. This book was released on 2023-09-04 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last book on the lactating sow was published over 15 years ago. This new book brings us up to date in current knowledge on the gestating and lactating sow. It covers new and important topics such as conditioning of gilts for optimal reproductive performance, feeding high fibre diets to gestating sows and providing various fat sources in gestation and lactation. It also describes the several key success factors to group-housing systems in gestation, which is a must due to the current move towards group-housing. The new concept of transition feeding for sows is discussed, as well as the factors involved in mammary development of gilts and sows, both of which are instrumental for maximum colostrum and/or milk yields. The impact of the human-animal interactions on sow welfare and performance is discussed with focus on new handling practices that could be developed to overbalance the negative interactions inherent to pig management systems. Updates on must-have topics, such as amino acid and energy requirements of sows, colostrum and milk yield and composition, and sow health are also provided. The subjects covered in this book will assist animal scientists, nutritionists, veterinarians and swine producers in learning the most recent information on relevant and current topics affecting sow production, and in knowing which areas are in need of further research efforts.
Download or read book Alphaherpesviruses written by Sandra Knowles Weller and published by Caister Academic Press Limited. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.

Download or read book Nutrient Requirements of Beef Cattle written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-06-16 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.

Download or read book Recent research developments in food biotechnology written by Raffaele Porta and published by . This book was released on 2008-01-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes are highly efficient and naturally occurring catalysts allowing all the biochemical reactions and processes of life to happen. They are present in all food raw materials from both animal and plant origin. Due to the role played by numerous microorganisms in the production of foods and beverages, enzymes have been extensively and unwittingly used in the past centuries. In fact, for many thousands of years man has used naturally occurring microorganisms bacteria, yeasts and moulds and the enzymes they produce to make foods like bread and cheese, or drinks such as beer and wine. The Egyptians and Sumerians (2000 B.C.) developed fermentation for use in brewing and both bread- and cheese-making. Essential in the metabolism of all living organisms, the enzymes can also be used to drive chemical reactions outside their natural localization. When purified and added to food preparations, several enzymes are able to improve their flavor, texture, nutritional value and digestibility. In fact, enzyme efficiency, specificity and environmental friendliness led to their increased use in food processing. Food industry is constantly seeking advanced technologies to meet consumer demand and the enzymes are a useful biotechnological tool whose action can be controlled in the food matrix to prepare high quality products. Moreover, the enzymes facilitate chemical reactions otherwise impossible or requiring conditions that could damage or destroy the end product or which would need a too much high input of energy. Examples are the production of clear apple juice concentrates, which relies on the use of the enzyme pectinase, and the breakdown of starch to sugars. The latter process, originally carried out by boiling the starch with acid and, thus, requiring large energy inputs, takes place in the presence of enzymes in mild conditions, saving energy and preventing pollution of undesirable by-products. However, it was not until the mid of the past century that the rapid development in enzyme technology occurred, and only in the last 30 years the use of commercial enzymes has grown in the food industry, progressively becoming an important aspect of the manufacturing of particular foods, such as meat, vegetables, fruit, baked goods, milk products, and both alcoholic and non-alcoholic beverages. Currently used food enzymes sometimes originate in animals and plants but most come from a range of beneficial microorganisms. Thus, numerous purified enzymes are now being widely used not only in food processing but also as food additives. In this respect, it is noteworthy that the enzymes, like all proteins, can cause reactions only when people have been sensitized through exposure to large quantities. Therefore, since their levels in the food are generally very low, the enzymes are highly unlikely to cause allergies. Finally, the recent advent of biotechnology has also allowed significant refinements in the methodologies offering unpredictable solutions to many persistent problems and opening up exciting new possibilities. Among these, enzymes are proposed as exemplary agents of green technology since they can also be used either to treat biological wastes or to prevent their formation. However, even though the first food application of a product of gene technology (alpha-amylase) took place in 1982, progress in this field is being slowed down because the debate on some other more controversial applications of genetic engineering in animals is continuing throughout Europe. This book highlights the rapidly expanding field of enzyme applications in food technology, explaining how the biocatalysts bring advantages in some food processing improvement and innovation. The properties of different enzymes are linked to the physical and biochemical events that they influence and are related to the key nutritional, organoleptic and shelf-life qualities of food. In this context, the chapters explore also recent developments in the use of some enzymes as well as the discovery of applications of new enzymes.
