This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments were performed in order to test the effect of different plastic coverings, and covering systems for use in sealing bunker silos. The objective of the first experiment was to evaluate the use of three plastic coverings using laboratory silos. Silos were filled with 14 kg of whole-plant corn forage (37% DM) to a packing density of approximately 223 kg of DM/m 3, and were covered with a) 6 mil black/white polyethylene (P0), b) a 1.10 mil thick oxygen barrier plastic (P1), or c) a 1.77 mil thick oxygen barrier plastic (P2). Buckets were sealed and stored at between 20 and 32°C. Buckets were opened at 181 d after ensiling. Laboratory silos covered with P0 tended to have more silage spoiled at the surface compared to P1 and P2. Total DM recovery from the silos tended to be lower in P0 than P1. In addition, P2 tended to have a lower concentration of acetic acid than P0. All other fermentation and chemical contents were similar among treatments. In a second experiment, two different plastic covering systems were assessed as coverings for farm-scale bunker silos. Three silos were filled with about 550 t of whole-plant corn forage. One half of each silo was sealed with one of two covering systems. The traditional system was comprised of covering the silo surface with a 6 mil polyethylene plastic that was weighted down with split tires. A modified system was comprised of a single layer of 1.77 mil oxygen barrier plastic used as sidewall plastic and as a covering on top of the silo. A protective tarpaulin was also placed over the surface plastic, and was weighted down with gravel bags along the length of the sidewall and at the seams. Corn silage was sampled at 5 months post-ensiling. In silos covered with the traditional system, water from rain and melting snow was able to infiltrate into the silage mass closest to wall resulting in poor quality silage. Silage sampled further from the wall was generally of better quality than silage nearer the wall. Silage quality was maintained and not affected by water in silos covered with the modified system. Silage sampled furthest from the wall (not affected by water) had some indices of nutritive value and fermentation end products that were better than silage stored under the traditional plastic. In a third experiment, the same three bunker silos were used to evaluate the use of a thicker 5 mil oxygen barrier plastic (weighted down with gravel bags but not requiring the use of a protective tarp) to normal 6 mil plastic (weighted down with split tires). Side wall plastic was used in both treatments. After 6 months of ensiling, samples were taken at the midpoint of each treatment. In general there was no major advantage in using oxygen barrier plastic in this experiment perhaps because the use of gravel bags as a weighting method was not effective in keeping the plastic flush against the silo surface. This allowed for air to penetrate the plastic through points where animals had caused some damage, resulting in the plastic to balloon in certain sections of the silo. The thicker oxygen barrier plastic did not appear to cling as tightly to the surface of the silage as the thinner oxygen barrier plastic did in the first field experiment, making it necessary to implement a better weighting method for this type of plastic in future experiments.

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.

Download or read book Nutritional Strategies of Animal Feed Additives written by Abdel-Fattah Z. M. Salem and published by NOVA. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality of feed nutrition is influenced not only by the content but also by some other aspects such as, feed presentation, hygiene, anti-nutritional factors, digestibility and palatability. Feed additives provide a mechanism by which such dietary deficiencies can be addressed and also benefits not only associated with the nutrition and thus the growth rate of the animal concerned, but also its health and welfare. Feed additives could modify animal metabolism in specific and direct ways by improving production efficiency (weight gain or milk yield); improving carcass composition in growing animals; increasing milk yield in lactating animals; and decreasing animal waste per production unit. This book discusses the impacts of feed additives on animal metabolism, health and production.
Download or read book Bulk Solids Handling written by C.R. Woodcock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding ofthe properties and the handling characteristics of liquids and gases has long been regarded as an essential requirement for most practising engineers. It is therefore not surprising that, over the years, there has been a regular appearance of books dealing with the fundamentals of fluid mechanics, fluid flow, hydraulics and related topics. What is surprising is that there has been no parallel development of the related discipline of Bulk Solids Handling, despite its increasing importance in modern industry across the world. It is only very recently that a structured approach to the teaching, and learning, of the subject has begun to evolve. A reason for the slow emergence of Bulk Solids Handling as an accepted topic of study in academic courses on mechanical, agricultural, chemical, mining and civil engineering is perhaps that the practice is so often taken for granted. Certainly the variety of materials being handled in bulk is almost endless, ranging in size from fine dust to rocks, in value from refuse to gold, and in temperature from deep-frozen peas to near-molten metal.
Download or read book Forages and Grazing in Horse Nutrition written by Markku Saastamoinen and published by Brill Wageningen Academic. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forages should be the basis of all diets in horse feeding. Therefore it is of major importance to determine which parameters will influence their quality. Changes on chemical composition along the vegetative cycle, nutrient losses during harvesting, preservation and storage are factors that could have an effect on nutritive value, as well on digestibility and palatability. A specific grazing and ingesting behaviour, linked to plant preferences and the selection of feeding sites will have an impact on biodiversity. This will determine the options on plant species and varieties and further management of pastures for horses. This book highlights the role of forages and grazing in horse nutrition and also gathers information about related topics, such as the contribution of local breeds for the sustainability and development of rural areas, their impact on landscape and relationships with environmental preservation. This book is the 6th volume in a scientific series conceived through the European Workshop on Equine Nutrition (EWEN) which falls under the umbrella of the Horse Commission of the European Federation of Animal Science (EAAP). All these materials provide an interesting basis for further discussion, not only in specialized forums, but also for those involved in horse production.
