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
With the dramatically rising sophistication of biological methods and products and the increasing use of recombinant DNA technology, now is an apt time to review the status of biotechnology in animal feeding. This book gives succinct yet comprehensive coverage of products of biotechnology and allied sciences used in animal feed and feeding industries. Particular emphasis is placed on: - Conservation and upgrading of feeds and feed components - Increasing the protein value of feeds - Antimicrobials - Microbial feed additives - Increasing the energy value of feeds. Moreover, increasing environmental concerns are reflected in chapters describing dietary products which may help to reduce environmental hazards from animal feeding enterprises. A discussion of social and legislative aspects relating to biotechnology and animal feeding rounds off this useful compilation of timely articles.

Book Description
This project was designed to test the biological effects of three levels of dietary protein (12.7, 16.3 and 19.3% CP on a dry matter basis) on high producing Holstein-Friesian dairy cows. Forty five second lactation or older cows that showed the potential to produce over 31.75 kg (70 lbs) per day were selected. Cows were randomly assigned to treatments on day four postpartum and remained on the trial for 90 days. A complete isocaloric ration was fed, consisting of corn or grass silage, alfalfa hay and a grain concentrate. Four percent fat-corrected milk production did not differ significantly between groups averaging 29.4, 31.3 and 32.0 kg/cow/day for the 12.7, 16.3 and 19.3% CP rations, respectively. Actual milk production was significantly higher in the 16.3% CP group than the 12.7% CP group. Group averages were 30.94, 35.52 and 34.79 kg/cow/day for the 12.7, 16.3 and 19.3% CP rations, respectively. Milk fat concentration averaged 3.66, 3.21 and 3.46% for the 12.7, 16.3 and 19.3% CP rations, respectively. The average for 16.3% CP ration cows was significantly different from the averages of the 12.7 and 19.3% CP ration cows. Milk fat concentration for all cows was 3.7% for period one (1-30 days), 3.21% for period two (31-60 days) and 3.46% for period three (61-90 days). Milk fat % was greater (P

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.

Book Description
This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.
