Download or read book Effect of Inclusion of Dried Distillers Grains in Small Ruminant Diets on Ruminal in Situ Nutrient Disappearance from Alfalfa and Cottonseed Hulls written by Rachel Ann Allphin and published by . This book was released on 2009 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of dietary distillers' grains (by-product from ethanol production) on ruminal in situ nutrient disappearance from alfalfa and cottonseed hulls were measured in four ruminally cannulated goats. Alfalfa and cottonseed hull residual samples were collected and analyzed for dry matter, organic matter, acid detergent and neutral detergent fiber. Ruminal in situ nutrient disappearance from alfalfa and cottonseed hulls was not affected ( P>0.05) by the inclusion of distillers' dried grains in goat diets at levels up to 20% of the total ration. These results indicate that dried distillers' grains can be used as a feedstuff for growing goats without adversely affecting ruminal fermentation of other nutrient sources in the diet.

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.

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 Effect of Dried Distillers Grains with Solubles on Greenhouse Gas Emissions from Beef Cattle written by Martin Hünerberg and published by . This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted to determine the impact of dried distillers' grains with solubles (DDGS) on greenhouse gas (GHG) emissions from beef cattle. The first compared in vitro methane (CH4) production from corn DDGS (CDDGS, ~30% crude protein [CP]) and wheat DDGS (WDDGS, ~40% CP dry matter [DM]). Wheat DDGS or CDDGS replaced barley silage at 20, 40, 60, 80 and 100% DM. Methane (mg CH4/g DM) was lower for CDDGS than WDDGS at up to 80% DM. In a second experiment, heifers fed a growing (high silage) diet showed a reduction in CH4 (g CH4/kg DM intake [DMI]) when 35% barley grain and 5% canola meal DM were replaced with CDDGS (10.0% fat DM). Inclusion of 40% WDDGS (4.1% fat DM) had no effect on enteric CH4 emissions. In contrast, feeding 40% DM WDDGS with added corn oil (9.5% fat DM) reduced CH4 to the same extent as CDDGS. In a third experiment, replacing 40% DM barley grain with CDDGS (9.7% fat DM) in a finishing (high grain) diet reduced CH4 (g/kg DMI). Whereas feeding 40% DM WDDGS along with corn oil (9.9% fat DM) resulted in similar CH4 losses as CDDGS. Results from both in vitro and in vivo experiments indicate that the higher fat content of CDDGS vs. WDDGS was responsible for CH4 reductions. The benefit of replacing 40% DM barley grain with CDDGS or WDDGS on GHG emissions from beef production was further evaluated using life cycle assessment. Replacing barley grain with CDDGS or WDDGS increased N intake and subsequently N excretion. Increased N excretion was predicted to outweigh reductions in CH4 through increased formation of nitrous oxide (N2O). Therefore, feeding CDDGS and WDDGS resulted in 6.3 and 9.3% higher GHG intensity (kg CO2 equivalent [CO2e]/kg beef) compared to the control. To reduce the environmental impact, DDGS should not be fed at inclusion levels that exceed N requirements of feedlot cattle.
Download or read book Principles of Animal Nutrition written by Guoyao Wu and published by CRC Press. This book was released on 2017-11-22 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals are biological transformers of dietary matter and energy to produce high-quality foods and wools for human consumption and use. Mammals, birds, fish, and shrimp require nutrients to survive, grow, develop, and reproduce. As an interesting, dynamic, and challenging discipline in biological sciences, animal nutrition spans an immense range from chemistry, biochemistry, anatomy and physiology to reproduction, immunology, pathology, and cell biology. Thus, nutrition is a foundational subject in livestock, poultry and fish production, as well as the rearing and health of companion animals. This book entitled Principles of Animal Nutrition consists of 13 chapters. Recent advances in biochemistry, physiology and anatomy provide the foundation to understand how nutrients are utilized by ruminants and non-ruminants. The text begins with an overview of the physiological and biochemical bases of animal nutrition, followed by a detailed description of chemical properties of carbohydrates, lipids, protein, and amino acids. It advances to the coverage of the digestion, absorption, transport, and metabolism of macronutrients, energy, vitamins, and minerals in animals. To integrate the basic knowledge of nutrition with practical animal feeding, the book continues with discussion on nutritional requirements of animals for maintenance and production, as well as the regulation of food intake by animals. Finally, the book closes with feed additives, including those used to enhance animal growth and survival, improve feed efficiency for protein production, and replace feed antibiotics. While the classical and modern concepts of animal nutrition are emphasized throughout the book, every effort has been made to include the most recent progress in this ever-expanding field, so that readers in various biological disciplines can integrate biochemistry and physiology with nutrition, health, and disease in mammals, birds, and other animal species (e.g., fish and shrimp). All chapters clearly provide the essential literature related to the principles of animal nutrition, which should be useful for academic researchers, practitioners, beginners, and government policy makers. This book is an excellent reference for professionals and a comprehensive textbook for senior undergraduate and graduate students in animal science, biochemistry, biomedicine, biology, food science, nutrition, veterinary medicine, and related fields.

Download or read book In Vitro Apparent Ruminal Digestibility of Diets Containing Corn Distillers Grain with Different Quantities of Crude Fat written by David Williams and published by . This book was released on 2017 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four dual-flow continuous fermenters were used in a Latin square design to determine the apparent ruminal digestibility and ruminal characteristics of diets containing dried distillers grains plus solubles (DDGS) at various levels of fat content. Fermenters were randomly assigned to one of the following treatments: 1) 40% DDGS containing 4.82% fat content (40 LOW); 2) 40% DDGS plus corn oil to obtain 7.5% fat (40 MED); 3) 40% DDGS plus corn oil to obtain 10.5% fat (40 HIGH); or 4) 70% DDGS plus corn oil to obtain 7.5% fat (70 MED). Rumen fluid was collected at the beginning of each period from two ruminally cannulated Angus cows previously adapted to the 40LOW treatment. Each period consisted of 10 days with a seven day adaptation period followed by three days of sample collection. Calories per gram of diet increased as percent fat increased and calories per gram was greater at the 70% inclusion of DDGS compared to 40% inclusion of DDGS at all levels of fat content. However, level of fat in the diet did not influence (P ≥ 0.35) apparent ruminal digestibility of DM, NDF, ADF, CP or total calories. Similarly, inclusion rate of DDGS had no influence (P ≥ 0.35) on nutrient digestibility. Ammonia concentrations were greatest (P = 0.0002) for 70 MED compared to the other treatments. However, treatment had no impact (P ≥ 0.16) on volatile fatty acid production with the exception of propionate which increased (P =0.05) as the level of DDGS increased from 40 to 70% inclusion rate. This data would suggest that level of fat content of DDGS has no negative influence on apparent ruminal digestibility and select ruminal characteristics. From an economic perspective, higher fat DDGS should have a higher price differential, but lower fat DDGS can still be an effective protein and energy substitute.
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.

This book was released on 2016 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its entirety this dissertation intended to address the impact of feeding several forms of de-oiled corn distillers grains plus solubles and the effect of supplementing OmniGen-AF as a potential antioxidant source for extending beef shelf life. In study one we learned that despite the de-oiling process, greater inclusion levels (65%, DM basis) of de-oiled wet distillers grains plus solubles (WDGS) causes an increase in polyunsaturated fatty acids (PUFA) similar to the levels obtained with full-fat WDGS. Lower inclusion levels (35 and 50%, DM basis) of de-oiled WDGS have intermediate PUFA content in comparison to 65% de-oiled WDGS, full-fat WDGS and a corn control diet (P 0.01). In study two cattle finished with 50% de-oiled dry distillers grain plus solubles (DDGS) also resulted in an increased PUFA content in muscle in relation to a corn control group (P
