Book Description
The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has a long history of coordinating isotope aided research projects for improving animal productivity in developing countries. These projects have focused on enhancing the efficiency of animal production through better use of locally available feed resources and those that do not compete with human food. As a part of these efforts, the Joint Division has been actively involved in developing and simplifying approaches for measuring microbial protein supply to ruminant livestock. The contribution of microbial protein in meeting the overall requirement for protein in ruminants is significant, but understanding the contribution of microbial protein to the nutrition of ruminant livestock has been hampered by the lack of simple and accurate methods for measuring microbial protein production in vivo. A Consultants’ Meeting was held in 1995 in Vienna to explore the feasibility of using nuclear and related techniques to develop and validate new approaches for measuring microbial protein supply in ruminant animals. Based on the available information, the consultants considered that the purine derivative excretion method, which is non-invasive and both simple to use and inexpensive compared with other available methods, had the potential for use in developing countries. However, development of models for various animal species and breeds and their validation were required before this technique could be advocated for use.

Book Description
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

Book Description
The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Book Description
Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.

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.
