The field of animal nutrition and feed technology has moved forward at an accelerated pace year by year. The present book is a result of the author’s long experience in the field whereby which the information documented has been presented in a simple, illustrative and lucid manner keeping in the mind the level of the readers. Less important information has been eliminated, while the general framework, character and flavour of the literature have been preserved, the text presents the animal nutrition and feed technology in an updated manner with the interpretation for the theory in practical manner.

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

'Applied Animal Feed Science and Technology' explores and suggests practical ways of improving the value of animals through supplementation.It begins by refreshing the reader on the classes of feeds consumed by livestock, their digestive systems and pertinent scientific issues that the farmer and the scientist alike need to pay attention to as they strive to nourish livestock for profitable commercial production.It goes on to look at the science and techniques of supplementing dairy cows, beef, poultry, ostrich, pigs, sheep, goats, horses, rabbits and game. The author believes in Value-Added Agriculture and, as such, an attempt is made in this book to help stakeholders in the livestock industry do the same to animals through supplementation. This is vital, especially for the developing world where wealth creation through Value-Added Agriculture is still lagging behind.Dr Irvin Mpofu also gives a lot of suggestions for the 'do-it-yourself farmer'. He goes on to give details on how technology, especially biotechnology, can accentuate animal production. Feed formulation and stock feed manufacturing issues are tackled for the benefit of 'would-be' entrepreneurs, students and animal science practitioners. Dr Irvin Mpofu also believes in precision agriculture, and throughout the book he impresses upon the reader the importance of giving the right feed to the right animal and in correct quantities with minimum or no wastage. The motto of the book is that no ordinary animal should ever be allowed to produce an ordinary result.

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.

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.

Extrusion is widely used for the preparation of a variety of foodstuffs including breakfast cereals, snack food and pasta, as well as pet food and animal and aquaculture feed. Extrusion problems solved provides responses to more than 300 frequently asked questions about the process of food extrusion and the techniques and equipment involved, in a practical question-and-answer format.The book is divided into twelve chapters for ease of reference: the opening chapters concentrate on introductory queries and on different components of an extruder system, followed by two chapters that help the reader select the correct type of extruder for a product. Chapters five and six discuss the impact of factors such as protein content and particle size on the extrusion process, while the use of pre-conditioners is discussed in chapter seven. The latter part of the book discusses specific types of extruder and die and knife assemblies, followed by a chapter on issues relating to drying extruded food products. The final chapter offers practical guidelines and rules of thumb for the most common issues relating to food and feed extrusion.Written by two leading experts in the field, Extrusion problems solved is an essential reference source and troubleshooting guide for professionals working in food, pet food and feed extrusion. It will also be a valuable training resource for students of extrusion. - Offers practical guidelines and rules of thumb for the most common food and feed extrusion problems - Chapters concentrate on introductory queries, types of extruder and components of extruder systems, knife assemblies, the use of pre-conditioners and issues in drying extruded food products - Provides responses to more than 300 frequently asked questions about the processes, equipment and techniques of food extrusion in a practical question-and-answer format
