Download or read book Recent Advances in Animal Nutrition – 1979 written by William Haresign and published by Elsevier. This book was released on 2013-10-22 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Animal Nutrition-1979 is a collection of studies that tackles the nutritional concerns of both ruminant and non-ruminant livestock. The book presents a total of 11 materials that cover the measurement of nutritional value of feeds up to the inter-relationships between nutrition, body condition, and reproduction of livestock. The text first tackles the nutritional availabilities in livestock diets, and then proceeds to dealing with covering topics related to energy value of feeds, such as energy evaluation of cereals for pig diets; developments of the metabolizable energy system for ruminants; and predicting the metabolizable energy value of feeds for ruminants. The book also covers the effects of cereal processing and growth stimulants on the efficiency of ruminant production. The selection will be most useful to both researchers and practitioners of animal related disciplines, such agriculture and veterinary medicine.

Download or read book Recent Advances in Animal Nutrition written by W. Haresign and published by Elsevier. This book was released on 2016-07-29 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Animal Nutrition — 1982 focuses on the compositions of animal feeds. The book first discusses the presence of molds and mycotoxins in animal feeds. Controlling mycotoxin exposure, formation and effects of mycotoxins, and microbiology of feeds are described. The text surveys the anti-nutritive factors in animal feeds. Substances depressing digestion or metabolic utilization of proteins; substances reducing the solubility or interfering with the utilization of mineral elements; and substances inactivating or increasing the requirements of vitamins are discussed. The book also highlights oilseed meals for livestock feeding; the use of databases for the composition and nutritive value of animal feeds; and energy evaluation of poultry rations. The text underscores the influence of nutrition on hatchability, including the composition and size of hatching eggs; the right amounts of proteins, lipids, vitamins, and minerals; feed ingredients; and feeding practices. The book also discusses the energy and protein requirements of pigs and methods used in the analysis of the energy content of ruminant feeds. The selection is a good source of data for readers interested in studying the compositions of animal feeds.

Download or read book Copper in Animal Wastes and Sewage Sludge written by P. L'Hermite and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication constitutes the Proceedings of a Workshop held in Bordeaux (France) on 8th - 10th October, 1980, under the auspices of the Commissior: of the European Communities, as part of the CEC research programme on 'Effluents from Livestock' and the Concerted Action COST 68 bis 'Treatment and Use of Sewage Sludge'. Major changes have taken place in livestock production techniques in recent years. One of the most important developments has been in the field of animal nutrition. Animals are fed to gain maximum liveweight in close relationship with market requirements for carcass and meat quality. With regard to pig production, dietary formulation is based on scientific principles and feed includes a large variety of ingredients to supply optimum feed rations for 'standardised' animals. In order to increase growth rate and to improve feed conversion, copper is added to the ratio~s of fattening pigs in a number of countries, in accordance with the provisions of Council Directives concerning additives in feedingstuffs, as last amended by the 23rd Commission Directive of 4th July 1980.

Download or read book Trace-Element Contamination of the Environment written by D. Purves and published by Elsevier. This book was released on 2012-12-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hard to imagine a more concise summary of the prodigious work and voluminous publications in this field... This volume should be available to students at the undergraduate level, to those in law school, and to all seriously concerned about an extremely important problem. This review in Choice was just one of the many favourable comments that greeted the appearance of the first edition of this book when it appeared in 1977. Since then, there has been an explosion of interest in almost every aspect of research in environmental pollution. The aim of this new edition, however, remains the same i.e. to evaluate the global biological consequences of dispersal of trace elements, originally mined from localized limited deposits, in the environment. In treating the problems of metal contamination of the environment, the author considers the problems of environmental pollution involving metals and the problem of exhaustion of finite reserves of ores of metals, such as cadmium, copper, lead, mercury, nickel and zinc, as aspects of a single global problem. A broad picture is presented of the overall process of dispersal of trace elements in the environment and the biological consequences of this process are documented with the aid of an intensive list of references. The book will be invaluable as a definitive reference source covering this field of interest for a wide range of people (environmentalists and conservationists, those concerned with management of resources and waste disposal, and agricultural chemists and soil scientists.)

Available in PDF, EPUB and Kindle. Book excerpt: This book was written to provide an integrated account of barley, induding its cultivation, nature and uses. An attempt has been made to cut across the unjustified and obstructive divisions between pure science, applied science, technology, botany, biochemistry, agronomy, and so on. Limitations of space preclude the use of more illustrative material or references, or even complete accounts of various topics. However sufficient information is given to enable the reader to understand the general principles and to find his or her way readily into the literature to obtain further information. Emphasis has been placed on general principles rather than details. In becoming familiar with the literature one becomes acquainted with the effects of the cereal or religion, the English language and the development of agriculture and biochemistry. The comparison between 'parallel literatures' is often stimulating also. For example one is forced to conclude that many of the agricultural problems of poor 'seed vigour' would be overcome if seedsmen used the maltsters techniques for breaking dormancy and speeding 'post-harvest maturation'. Barley is the world's fourth most important cereal after wheat, rice, and maize. It is the most widely cultivated, being grown from the equator to 700N (Scandinavia), from the humid regions of Europe and Japan to the Saharan and Asiatic Oases, and from below sea level in Palestine to high up mountains in the Himalayas, E. Africa and S. America. Some where in the world it is being sown or harvested at every time of the year.

Download or read book Soils in the Urban Environment written by Peter Bullock and published by John Wiley & Sons. This book was released on 2009-05-13 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban areas contain a wide variety of open spaces, yet much of this has evolved under the pressures of human population with minimal management. The last 40 years have seen problems of varying severity begin to appear, including contamination, erosion, acidification and compaction. These problems have brought attention to the importance of the soil cover, the need for better understanding it, and the need for its protection. This book is a review of state-of-the-art science for soil in urban areas. Based on a meeting organized by the Nature Conservancy Council and the British Society of Soil Science, the nine chapters cover soil classification, contamination by waste and metals, physical and biological properties, nutrient provision and cycling, vegetation, and soil storage. The book provides a basis from which to plan future research and development programs.

Download or read book The Influence of Sewage Sludge Application on Physical and Biological Properties of Soils written by G. Catroux and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural value of sewage sludges is well known and a lot of published data has demonstrated the positive effects of sludge appli cations on plant growth and yield. These effects are probably due mainly to the nitrogen and phosphorus content of sewage sludges. But, as sludges are more organic than mineral, we can expect an effect of the organic matter added to the soil on soil fertility. Certainly, in the future, landspreading of sludges will be regulated, taking into account pollution hazards for waters (excess of nitrogen and phosphorus supply compared to plant needs and soil storage capacities) and for soils (excess of heavy metals supply and build up in soils). There will be regulations fixing what low level of sludges may be spread each year, decreasing their comparative value with respect to mineral fertilizers. In this eventuality, the organic value of sludges will take on a greater importance and several questions arise : - what is the lowest amount of sludge to be spread to have an immediate effect on soil physical properties? - are sludges effective on soil physical properties when spreading repeated low amounts? On the other hand, organic matter and soil biology are closely linked and there are few data on the possible effects - beneficial or detrimenta- on soil organisms.
