Pages : 383
Book Description
"This publication focuses on the various aspects of domestic animal recording, aimed at improving the management of herds and increasing their productivity. New strategies for recording are illustrated and the most updated technologies are presented, on the basis of national experiences where such technologies are already adopted. Although cattle is the prominent species, two parts are dedicated to small ruminants recording and to buffalo recording. Future challenges and opportunities for further development of ICAR and the definition of the future scenarios in the animal recording sector are also described. A special section is dedicated to 'Improving the health traits by recording and evaluation', where the past and future of animal recording and the use of animal recording data for genetic evaluation and breeding are defined. Another section deals with the 'ICAR Reference Laboratory Network', where the reference systems, the principles and the practices for calibration system for routine milk testing are presented. The publication ends with the national statistics on the 'Yearly enquiry on the situation of milk recording in member countries' for the years 2003 and 2004. A total of 45 pages describes the methodologies used at national level for milk recording, the national data for milk production, the costs of recording and the productivity and numbers of recorded cattle at national level (divided by species and by herdbook)."

Book Description
NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.

Weed Biology and Management
Author: InderjitPublisher: Springer Science & Business Media
ISBN: 9401705526
Category : Science
Languages : en
Pages : 550
Book Description
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.
Environmental Impact of Genetically Modified Crops
Author: Natalie FerryPublisher: CABI
ISBN: 1845934091
Category : Technology & Engineering
Languages : en
Pages : 440
Book Description
The genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. Included is a chapter by Bruce Tabashnik on the recent discovery of the first documented case of field-evolved resistance to a crop genetically modified to carry the gene for the Bacillus thuringiensis toxin. While the main focus is on environmental impact, food safety issues for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.

Book Description
During the past twentieth century, plant pathology has witnessed a dramatic advancement in management of plant diseases through in-depth investigations of host parasite interactions, integration of new concepts, principles and approaches. Our effort in brining out this book is to compile the achievements of modern times with regards to disease management of fruits which otherwise is widely dispersed in various scientific journals, books and government reports and to develop future strategies for the millennium. The chapters on individual crops are contributed by leading plant pathologists having authority in the respective field at international level. Each chapter includes the diseases of economic importance describing their history, distribution, symptoms, epidemiology, and integrated management approaches being adopted worldwide. Each chapter is vividly illustrated to make it more understandable to students, research and extension workers, planners, administrators and other end users citing pertinent references.
