This volume reviews key research and the challenges faced in developing new livestock feed products that promote growth whilst also enhancing both product quality and safety. This collection also summarises recent key developments in the sector, including a better understanding of gut function and the need to replace antibiotics.
The production of animal feed increasingly relies on the global acquisition of feed material, increasing the risk of chemical and microbiological contaminants being transferred into food-producing animals. Animal feed contamination provides a comprehensive overview of recent research into animal feed contaminants and their negative effects on both animal and human health.Part one focuses on the contamination of feeds and fodder by microorganisms and animal by-products. Analysis of contamination by persistent organic pollutants and toxic metals follows in part two, before the problem of natural toxins is considered in part three. Veterinary medicinal products as contaminants are explored in part four, along with a discussion of the use of antimicrobials in animal feed. Part five goes on to highlight the risk from emerging technologies. Finally, part six explores feed safety and quality management by considering the safe supply and management of animal feed, the process of sampling for contaminant analysis, and the GMP+ feed safety assurance scheme.With its distinguished editor and international team of expert contributors, Animal feed contamination is an indispensable reference work for all those responsible for food safety control in the food and feed industries, as well as a key source for researchers in this area. - Provides a comprehensive review of research into animal feed contaminants and their negative effects on both animal and human health - Examines the contamination of feeds and fodder by microorganisms and animal by-products - Analyses contamination by persistant organic pollutants, toxic metals and natural toxins
Current pressures to maximise the use of forages in ruminant diets have renewed interest in fast, inexpensive methods for the estimation of their nutritional value. As a result, a wide variety of biological and physiochemical procedures have recently been investigated for this purpose.This book is the single definitive reference volume on the current status of research in this areaCovers all forages eaten by ruminant animals
Students in animal science, industry personnel involved in the feeding of animals, and professionals working for feed-mixing companies will all benefit from this current, comprehensive package - a text on the economic and nutritional aspects of feed formulations that optimize nutritional content while minimizing costs. Animal Feed Formulation applies a well-tested, easy-to-use computer program called UFFDA that illustrates the principles of least-cost food formulation. Developed in a cooperative effort by the Departments of Poultry Science and Agricultural and Applied Economics at the University of Georgia, UFFDA is menu-driven software that has the editing capabilities of a spreadsheet program for altering the ingredient and nutrient matrix. The book begins by solving a simple ration-balancing problem, providing step-by-step instructions with the computer program that any user - even one without computer training - can readily follow. It then discusses specific feed formulation techniques in terms of their practical applications and economic implications. Included are such techniques as sensitivity analysis, parametric cost and nutrient ranging, optimum-density formulation, multi-blending, and risk analysis, among others. Applying these and other techniques using the special features of UFFDA, users can select the proper ingredients, adjust proportions among nutrients, determine which feeds might require scarce ingredients, consider the risks involved in dealing with ingredients with below-average compositions, and ultimately determine the costs and nutritional content of various feed formulations. The program can be applied to determining feed formulations for any animal, including sheep, beef and dairy cattle, swine, turkeys, broilers, catfish, and horses. Practitioners who are growing animals will be able to maximize the nutritional content of their feed while keeping costs down. Professionals working in feed-mixing companies will be able to maximize profits by offering products composed of low-cost ingredients that are also of good nutritional value. Students will gain a firm background in nutritional and economic concepts, insight into how to apply them to practical problems, and an understanding of the way good nutrition and good value can be achieved by applying the latest computer technology.
By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution-one
