Book Description
An experiment was conducted with 48 Yorkshire x Berkshire crossbred barrows to evaluate the influence of varying Calorie: protein ratios in high-fat rations on performance and carcass quality of growing-finishing swine. Pigs were individually fed rations containing three levels of fat (lard): 0, 15 and 30 percent. Each fat level was incorporated into rations differing by Calorie: protein ratio (Kcal. digestible energy per gram of crude protein). Two ratios were employed, based on (1) a ration containing 1500 Kcal. of digestible energy and 14 percent crude protein, approximately that commonly used in swine grower diets, and (2) a ration containing a similar energy level as (1), with the crude protein level raised to 20 percent. Responses were obtained over two growth periods (60-130 and 130-200 pounds live weight). Animals were slaughtered after exceeding a weight of 200 pounds and carcass data were collected. Pigs consuming the higher protein diets exhibited a significantly poorer average daily gain (P

Book Description
'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.

Book Description
With 42 chapters authored by leading international experts, Swine Nutrition: Second Edition is a comprehensive reference that covers all aspects of the nutrition of pigs. Content includes characteristics of swine and the swine industry with emphasis on the gastrointestinal tract; various classes of nutrients, how these nutrients are metabolized by swine, and the factors affecting their utilization; the practical aspects of swine nutrition from birth through gestation, lactation in sows, and the feeding of adult boars; and nutritional aspects of the various feedstuffs commonly fed to swine. Rounding the book is coverage of various techniques used in swine nutrition research.

Book Description
Swine Nutrition is a comprehensive text-reference that deals with the various aspects and knowledge in swine nutrition. The book is basically about nutrient utilization by swine. The topics discussed concerning this subject are factors influencing swine nutrition, nutrient bioavailability, appetite and feeding behavior, physical forms of feed, environment and management, immunocompetence, genetic and sex considerations, mycotoxins, and intestinal microbiology. Major and unique feedstuffs, feeding regimen in different stages of growth, and techniques in swine nutrition research are also elaborated. The text will be useful to students of advance swine nutrition courses as well as those seeking information in swine nutrition.

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.
