Download or read book Feeding Rumen protected Methionine During Pre and Postpartum Period in Dairy Cows written by Mateus Zucato Toledo and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methionine (Met) is one of the most studied and characterized functional amino acid with several functions such as DNA methylation, synthesis of other molecules (e.g choline, polyamines, and carnitine,), and antioxidant balance. Thus, Met is an AA of potential interest during the periparturient period for dairy cows and may improve health, and consequently lactation and reproductive performance. The main hypothesis of this dissertation was that feeding rumen-protected Met (RPM) in a total mixed ration (TMR) during the pre- and postpartum period would increase plasma Met concentrations and improve lactation, reproductive performance, and health of dairy cows. The main projects were a collaboration between University of Wisconsin-Madison and Cornell University to enroll a large number (> 400) of cows in a pen-based design. Cows fed RPM had greater lactation performance via increased milk protein yield (overall +50 g) and concentration (+0.12 percentage units), and milk fat concentration (+0.10), but other lactation response variables were unaffected. In addition, cows fed RPM in the TMR had increased plasma Met during the periparturient period (+38%) and at a later stage of lactation (+86 to 105%) consistently throughout the day, with no changes in other AA. We observed no effect on overall reproductive efficiency, nor on the incidence of clinical health disorders. However, cows fed RPM had a reduced the number of cows with subclinical hypocalcemia on the day of parturition (-38%; UW only) and tended to have a reduced number of cows culled/sold (-32%; UW and CU). An analysis of the interaction of health disorders and RPM feeding showed that RPM feeding alleviated negative impacts of health disorders on production and reproduction. For example, feeding RPM increased milk protein production (+70 g) and reduced the time to pregnancy (mean decrease of 24 d) in cows with health disorders but not in cows without health disorders. In conclusion, feeding RPM during the pre- and postpartum period increased plasma Met and milk protein production. In contrast, feeding RPM did not reduce incidence of specific health disorders, except subclinical hypocalcemia, and did not produce any overall improvement in reproductive performance. Nevertheless, the results from these studies provided evidence to support a novel hypothesis that additional metabolizable Met, provides positive effects on production and reproduction but only in cows with health disorders and not in cows without health disorders. Since this concept was discovered during exploratory analysis of our results, important biological and practical implications and needs to be considered and thoroughly tested in future research on Met in reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an in-depth description of different groups of microbes (i.e. bacteria, protozoa, fungi and viruses) that exist in the rumen microbial community, and offers an overview of rumen microbiology, the rumen microbial ecosystem of domesticated ruminants, and rumen microbial diversity. It provides the latest concepts on rumen microbiology for scholars, researchers and teachers of animal and veterinary sciences. With this goal in mind, throughout the text we focus on specific areas related to the biology and complex interactions of the microbes in rumen, integrating significant key issues in each respective area. We also discuss rumen manipulation with plant secondary metabolites, microbial feed additives, utilization of organic acids, selective inhibition of harmful rumen microbes, and ‘omics’ approaches to manipulating rumen microbial functions. A section on the exploration and exploitation of rumen microbes addresses topics including the current state of knowledge on rumen metagenomics, rumen: an underutilized niche for industrially important enzymes and ruminal fermentations to produce fuels. We next turn our attention to commercial applications of rumen microbial enzymes and to the molecular characterization of euryarcheal communities within an anaerobic digester. A section on intestinal disorders and rumen microbes covers acidosis in cattle, urea/ ammonia metabolism in the rumen and nitrate/ nitrite toxicity in ruminant diets. Last, the future prospects of rumen microbiology are examined, based on the latest developments in this area. In summary, the book offers a highly systematic collection of essential content on rumen microbiology.
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 Genetics of Animal Health and Disease in Livestock written by Bianca Castiglioni and published by MDPI. This book was released on 2021-06-02 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood surface attributes can be established by examining its several different physical or chemical properties. Differences in the wood surfaces occur between the manufacturing and post-treatment processes as well. Understanding how their unique anisotropic molecular organization, chemical linkages, branching, and other molecular features govern micro- and macroscale accessibility is essential for coating and complex modification processes. It is therefore important for scientific as well as practical reasons to qualify and quantify the effects of wood surface treatments and modifications. Challenges still exist to fully understanding the effect of the numerous applied chemicals and the wide range of treatment processes on wood surfaces.

Download or read book Studies on Veterinary Medicine written by Lester Mandelker and published by Springer Science & Business Media. This book was released on 2011-03-03 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compendium of research material on the role of oxidative stress in animal disease and morbidity examines both the general and the specific. Sourced from scientists, veterinarians, and members of the medical community from around the world, it includes chapters on our wider understanding of the corrosive function of free radicals in cell biology as well as focusing on the interplay between oxidative stress and metabolism in a variety of animal species including dogs, ruminants and birds. Since biogerontologist Denham Harman first posited that free radicals arising from the metabolic activity of oxygen play a central role in aging and disease, a mass of evidence has accumulated linking oxidative stress and biological degradation. We now understand that living in an aerobic environment inevitably leads to the production of free radicals that go on to attack biological membranes and lipoproteins via oxidation in a process called lipid peroxidation. Reacting with carbon-based molecules such as polyunsaturated fatty acids, these free radicals cause oxidative stress and tissue damage. The purpose of Studies on Veterinary Medicine is to inform clinicians, students and others of the plethora of consequences that free radical damage (ROS) has on various cells, tissues, and organs, as well as in different species of animals. The chapters also analyze the effects of oxidative stress on aging and various morbidities such as diabetes, cognitive dysfunction and heart disease. Contributors variously present their interpretation of the role played by oxidative damage in disease and assess the benefits of antioxidant therapies.

Book excerpt: Dairy farming is one of the fastest growing and developing subsectors in the agricultural industry. There has been unprecedented growth in milk production attributed by proper genetic selection, breeding, housing, and feeding programs in this subsector. Dairy farming for milk production has been the primary business for many people in different places around the world. Milk has also been and still is a key animal product in most diets consumed worldwide. With various advancements achieved in preservation of techniques for dairy products, preference of consumers for milk and milk products are higher than ever. Basic information on the technology and science used in production and processing this crucial food commodity is significant to the work of academia, governments, and industry.Several good and professionally prepared reference books are available, but the preference for any specific book greatly depends on the needs for the reader. Most of the dairy farming reference books are single-volume books, and others only cover general topics whereas other books cover specific dairy farming topics. This book has been prepared to offer essential information about basic principles involved in milk production, nutritional requirement for dairy cattle, basic management practices involved in dairy farming and health conditions that affect dairy cows in milk production to all those student taking dairy farming management courses, veterinary professionals, teachers, dairy management staffs, and even various governmental staffs involved in agricultural sectors. The general science and various production practices presently in use in dairy industry have been characterised and well described so that the reader can acquire insights into the industry. The book has been divided into four sections. Section one deal with general information and principles on dairy farming and it consist of only one chapter. Section two deals with background information on nutrition requirements in milk production and consists of four chapters. Section three deals with general management practices involved in dairy farming for maximum milk production and consist of four chapters. Lastly, section four dealing with dairy farming health problems consists of one chapter. More emphases have been put in nutrition and management practices of dairy cow because these are the two key areas where most breeders and producer focus on in order to enhance milk production. Specific areas tailored towards minimizing production costs and maximizing overall production have also received much of the attention, specifically on the second, third and fourth section of the book
Download or read book Milk Quality written by F. Harding and published by Springer. This book was released on 2013-12-14 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk has played a major contribution to the human diet in many different countries across the world since the dawn of time. The dairy cow was domesticated over 6000 years ago, she was the object of worship in the Middle East 2000 years before Christ, and milk and milk products are mentioned more than 50 times in the Bible. Milk and dairy products have become a major part of the human diet in many countries. It is not surprising therefore, that over many years considerable attention has been paid to improving the quality of milk. We have worked to improve the yield, the compositional quality and the hygienic quality, and have striven to minimise the level of contaminants which can find access to this, perhaps our most natural, unrefined and highly nutritious foodstuff. The chain of people involved in the milk industry extends from milk production-farmers, veterinarians and farm advisors-through transport to processing-quality controllers, manufacturers-and on to retailers, legislators, nutritionists, dairy educators and consumers. All will be interested in the quality parameters of milk which are reg ularly measured for commercial reasons, for trade, for legal requirements and for reasons of nutrition.
