Book Description
In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.

Book Description
In 3 experiments, 4,720 pigs were used to determine the effects of: 1) dietary fat and feeding duration on growth performance and fat quality in finishing pigs; or 2) a novel protease or 3) increasing levels of Zn amino acid complex (ZnAA) or ZnO on finishing pig performance. Experiment 1 tested the effects of feeding tallow, soybean oil, or a blend of the two for various feeding durations (d 0 to 42, 42 to 84, or 0 to 84). Overall, pigs fed added fat for the entire 84 d had improved G:F compared to those fed a control diet. Additionally, pigs fed additional fat for the entire study had improved ADG and G:F as well as increased d 84 BW compared to pigs fed additional fat for 42 d. Increasing the feeding duration of soybean oil lowered monounsaturated fatty acids and increased polyunsaturated fatty acid concentrations while these values remained relatively unchanged by the addition of tallow. There were feeding period by fat source interactions for fatty acid composition and iodine value for belly and backfat, but not jowl fat, indicating a longer turnover rate for jowl fat compared to belly or backfat. In Exp. 2, adding a protease to a nutrient deficient diet increased ADFI and tended to increase ADG compared to pigs fed a negative control diet. There were no differences observed in ADG, ADFI, or G:F between pigs fed a positive control diet, formulated to 90% of the pigs SID lysine requirement, and those fed a negative control diet plus the protease, which would suggest the release values attributed to the enzyme were accurate. In Exp. 3, supplementing additional Zn from either ZnAA or ZnO at 25, 50, or 75 ppm in finishing diets for commercial finishing pigs was evaluated. Overall, no differences were observed in ADFI, but a Zn source by level interaction was observed for ADG and G:F, as pigs fed increasing ZnO were observed to have similar performance, while pigs fed added levels of 25 and 50 ppm Zn from ZnAA had decreased performance compared to those fed the highest level of ZnAA.

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
The tenth edition of this essential reference presents new knowledge about the nutritional needs of swine that consider such factors as growth rate, carcass leanness, gender, health, environment, and repartitioning agents. New sections are presented on requirements for amino acids and other nutrients. In addition, an original modeling approach to arriving at energy and amino acid needs for given animals is incorporated in this revision. The book comes with a CD-ROM that allows users to create tables of nutrient requirements for swine of a specific body weight and level of productivity. Nutrient Requirements of Swine covers: Biological concepts that underlie nutrient needs for growth and function. New data on amino acid and energy requirements and the factors that shape them. New findings on lysine and the bioavailability of amino acids. New research results on minerals and vitamins. Nutrient composition of an expanded list of feedstuffs. The role of water in swine physiology, including factors that affect the quality of drinking water. Expanded tables of feed ingredients and their nutrient composition provide bioavailability estimates, fatty acid composition of fats typically used in swine diets, and important information on estimating the amino acid content of crude protein.

Book Description
Recent Developments in Pig Nutrition shows the updates in the nutrition and the evaluation of energy needs in raising and breeding pigs. The book covers the energy requirement of pigs; the effects of climatic variables on the nutrition and energy of pigs; and the prediction of energy content in pig feeds. The availability and importance of proteins and amino acids in pig feeds are also discussed. The text also explains the importance of vitamins and minerals in the diet of pigs; the nutritional needs of the different sexes of pigs and piglets; and the processing and evaluation of cereals for pig diets. The monograph is recommended for those in piggery business, who want to know more about the importance of pig nutrition and be updated with the different findings in the field. The book will also be good for animal nutritionists who concern themselves with pig feeds and for veterinarians who specialize in pigs.

Book Description
Since 1944, the National Research Council has published 10 editions of the Nutrient Requirements of Swine. This reference has guided nutritionists and other professionals in academia and the swine and feed industries in developing and implementing nutritional and feeding programs for swine. The swine industry has undergone considerable changes since the tenth edition was published in 1998 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eleventh revised edition of the Nutrient Requirements of Swine builds on the previous editions published by the National Research Council. A great deal of new research has been published during the last 15 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of swine in all stages of life, this volume includes information about feed ingredients from the biofuels industry and other new ingredients, requirements for digestible phosphorus and concentrations of it in feed ingredients, a review of the effects of feed additives and feed processing, and strategies to increase nutrient retention and thus reduce fecal and urinary excretions that could contribute to environmental pollution. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Swine represents a comprehensive review of the most recent information available on swine nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious swine production.
