Download or read book Investigations on the effects of niacin supplementation to different rations on rumen fermentation duodenal nutrient flow and several serum and milk parameters of dairy cows written by Inka-Donata Niehoff and published by Cuvillier Verlag. This book was released on 2009-11-02 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the incorporation of niacin into the coenzymes NAD and NADP, niacin is of great importance for the metabolism of man and animals. Apart from niacin in feed and endogenous formation, microbial niacin synthesis in the rumen is an important source for dairy cows. But the amount synthesized seems to differ greatly, which might be influenced by the ration fed. Many studies revealed a positive impact of a niacin supplementation on rumen protozoa, but microbial protein synthesis or volatile fatty acid production in the rumen showed inconsistent reactions to supplemental niacin. The amount of niacin reaching the duodenum is usually higher when niacin is fed. But not the whole quantity supplemented reaches the duodenum, indicating degradation or absorption before the duodenal cannula. Furthermore, supplementation of niacin did not always lead to a higher niacin concentration in blood. Effects on other blood parameters have been inconsistent, but might be more obvious when cows are in a tense metabolic situation, for example, ketosis or if high amounts are infused post-ruminally, since ruminal degradation appears to be substantial. The same is valid for milk parameters. In the few studies where blood niacin and milk parameters have been investigated, enhanced niacin concentrations in blood did not necessarily affect milk production or composition. These results are discussed in the present review, gaps of knowledge of niacin’s mode of action on the metabolism of dairy cows are identified and directions for future research are suggested.

These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded
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 Quantification and Mitigation Strategies to Reduce Greenhouse Gas Emissions from Livestock Production Systems written by Mizeck Chagunda and published by MDPI. This book was released on 2020-06-17 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.

Download or read book Rational Livestock Nutrition in Rural Areas written by Maja Słupczyńska and published by Tudás Alapítvány. This book was released on 2020-01-15 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock nutrition is one of the most important issue in animal production both in physiological-economic terms as well as the impact of livestock on the environment. The handbook „Rational livestock nutrition in rural areas” has been funded with support from the European Commission under Erasmus + programme – Cooperation for innovation and good practice. The book has been developed by experts in various fields of agriculture – animal nutrition and feed science, animal husbandry, agronomy and veterinary medicine. The authors of this book, originating from five different countries – Poland, Turkey, Romania, Italy and Hungary by working within the framework of the established Strategic Partnership – Vocational Education and Training have developed a comprehensive compendium aimed at transfer of knowledge, good practice and innovation in the field of agriculture with emphasis on rational nutrition of livestock. The book covers five broad issues of livestock nutrition. Chapter one – „Physiology of Nutrition”, is related to the anatomy and functions of particular organs of the farm animals’ digestive tracts, type of nutrients found in the livestock diets, as well digestion, absorption and metabolism of these compounds. An extensive characteristics of most common used in animal nutrition feeds, their processing, feed additives as well as the mechanism of their action are presented in the second chapter – „Feed and Feed Additives”. The chapter number three – „Animal Feeding Systems in Europe” in a synthetic way explains the fundamentals of commonly used feeding systems of ruminants, pigs, poultry, horses and rabbits. This chapter also provides several schemes of daily rations/concentrate mixtures formulation for various farm animal species. An extensive chapter number four is dedicated to animal welfare as well etiology, treatment and prevention of metabolic diseases in animals that livestock breeders are struggling every day. Last but not least, the fifth chapter raises issues related to livestock production in terms of environmental and legal conditions under the common agricultural policy of member countries. The possibilities of reducing the negative impact of livestock production on the environment, so called „good practices” are discussed in this chapter. The book “Rational Livestock Nutrition in Rural Areas” is intended for people involved in animal production – mainly farmers but it can also be used by agricultural and nutritional consultants, zootechnical service workers. Students of vocational agricultural schools and, to some extent, students of natural and agricultural universities may benefit this book as well.
