Download or read book Techniques in Free Radical Research written by A.T. Diplock and published by Elsevier. This book was released on 1991-12-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. ESR is the only technique which has the potential for direct detection of radicals but in biological systems even these must be trapped by a spin-trapping agent. Thus most investigations involve recognition of indicators of the presence of radicals in vivo or "FOOTPRINTS" of radical-mediated damage. Techniques in Free Radical Research assembles and critically assesses the most relevant and reliable experimental approaches used towards the measurement of radicals and radical-mediated damage in chemical systems, in cells and in tissues under the following six headings: a) Footprints of DNA damage, b) Footprints of protein damage, c) Footprints of lipid peroxidation, d) Footprints of antioxidant consumption, e) Footprints via indirect radical assays, and f) Footprints via the availability of transition metal complexes.
Download or read book Physiological Impacts and Lactational Performance of Dairy Cow Fed Brown Midrib Corn Silage During Dry Period Through Early to Midlactation written by Alexandra Windley Kelley and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing solutions to the metabolic stress experienced by cows during the transition period is very important because it can negatively influence lactational performance. The objectives were to: 1) compare physiological changes through body weight (BW) and concentrations of non-esterified fatty acids (NEFA) and Îø-hydroxybutyric acid (BHBA) and 2) evaluate feed intake, milk production, and energy balance (EB) of cows fed brown midrib corn silage (BMRCS)-based diets when compared with conventional corn silage (CCS)-based diets during the transition. At 4 wk prior to parturition, 40 dry multiparous Holstein cows were randomly assigned treatments. The treatment groups consisted of 2 close-up transition diets (CCS-based and BMRCS-based diet) offered to 2 groups of 20 cows each beginning at 4 wk prepartum. After calving, 10 cows from each prepartum group were individually fed one of four dietary treatments. The four dietary treatments postpartum were defined as follows: 1) CC = CCS-based close-up diet + CCS-based lactation diet; 2) CB = CCS-based close-up diet + BMRCS-based lactation diet; 3) BB = BMRCS-based close-up diet + BMRCS-based lactation diet; 4) BC = BMRCS-based close-up diet + CCS-based lactation diet. Cows were sampled weekly for feed intake, and feed composition was taken monthly. After calving, milk yields were recorded daily and milk components were analyzed monthly. Body weights were taken twice per week on wk -4, -2, 1, 2, 3, 4, 8, 12, 16, and 20. Blood serum was sampled 3 times per week from wk -4 through 4 and then on wk 6, 8, 14, and 20. Rumen fluid was sampled on wk -4, 4, 8, 14, and 20. Feeding BMRCS-based diets during the transition did have a positive influence on dry matter intake, milk production, and energy balance. Interestingly, feeding BMRCS-based diets only during the close-up period and feeding a CCS-based diet during the lactation had similar positive effects as feeding a BMRCS-based diet through the dry period and during the lactation. This finding is meaningful because producers, especially in the Intermountain West, have experienced BMR crop yields that have been less than that of conventional crop yields and may be unwilling to utilize BMRCS in dairy rations. However, if feeding a BMRCS-based diet for a limited amount of time is beneficial, producers could be more willing to utilize this silage hybrid as an important transition period management tool.

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Download or read book Nutrient Requirements of Dairy Cattle written by National Research Council and published by National Academies Press. This book was released on 2001-02-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.
Download or read book Precision Dairy Farming 2016 written by Claudia Kamphuis and published by BRILL. This book was released on 2023-09-04 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The supply of new innovative precision dairy farming technologies is steadily increasing. It aims to help farmers to be more labour efficient and to support them in their daily management decisions. At the same time, since many technologies are developed from an engineering perspective, adoption of these technologies is sometimes limited since knowledge on economic benefits and farmers' needs is often incomplete. This book covers the current status of precision dairy farming technologies and what farmers expect from them. It also includes insights and future perspectives on managing, analysing, and combining sensor information. Moreover, new innovative ideas that may better fit farmers' needs and expectation are introduced, ranging from technologies or innovations that aim at improved animal health and welfare, to those technologies that result in a more efficient use of feed and improved grazing management. This book is unique because science and engineering are combined to develop precision dairy farming technologies that are to be applied in practice. The book will serve as a stepping stone for new and innovative ideas within this rapidly growing area within dairy farming.

Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.
Download or read book Nutrition and the Welfare of Farm Animals written by Clive J. C. Phillips and published by Springer. This book was released on 2016-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal’s behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock. This book will provide a much-needed review of the relationships between nutrition and the welfare of farm animals.
