Book excerpt: 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.
Download or read book Feed efficiency in swine written by John F. Patience and published by Springer Science & Business Media. This book was released on 2012-10-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

Download or read book Influence of Diet and Sex on the Performance of Three Breeding Groups of Pigs Marketed at Three Different Weights written by Peter Joseph Skitsko and published by . This book was released on 1969 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were designed to study the influence of high and low energy diets under conditions of limit-feeding imposed by allowing pigs access to feed for two, 1 hr periods per day on the performance of three breeding groups of pigs marketed at three different weights. The diets contained approximately 3650 and 2750 kcal digestible energy per kg and had similar ratios of crude protein, lysine, methionine and cystine and calcium to digestible energy. Performance of the pigs was based on average daily gain, average daily feed consumption, feed conversion, digestibility of energy and nitrogen, nitrogen retention and carcass characteristics. A 2x2x2x3x3 factorial design consisting of two replicates, two diets, two sexes, three breeding groups and three market weights was used in these studies. In addition a Ix2x2x3 factorial experiment consisting of one breeding group, two diets, two sexes and three market weights was used to study the aforementioned parameters under self-feeding conditions. The high energy diet significantly improved average daily gain and feed conversion as compared to the low energy diet. However, when converted to the basis of digestible energy in Experiment 1, there were no differences in energetic efficiency between the pigs fed the high and low energy diets. Males had higher average daily feed consumption and, when the high energy diet was fed they had higher average daily gain than females. The males were less efficient converters of feed to gain when the low energy diet was fed but no differences in feed conversion existed between sexes when the high energy diet was fed. A significant difference between breeding groups was found for average daily gain and feed conversion; the Duroc and Hampshire-sired groups had a higher average daily gain and were more efficient converters of feed to gain than the Yorkshire-sired group. The digestibility of dietary energy and nitrogen was not affected by sex or breeding group. Nitrogen digestibility was increased when the high energy diet was fed. Nitrogen retention was not affected by diet, sex or breeding group. Carcasses of pigs receiving the high energy diet were fatter as evidenced by higher dressing percentages, greater total backfat thickness, decreased ratio of loin area to backfat thickness, lean in the ham face, ham as a percent of carcass and Record of Performance (ROP) score. Females were superior to the males in all carcass measurements except dressing percentage where differences were not significant. The Yorkshire-sired group were inferior to the Duroc and Hampshire-sired groups in dressing percentage and loin area but were superior in carcass length. Market weight had a significant effect on carcass characteristics. Dressing percentage, carcass length and loin area were improved with increases in carcass weight while the total backfat thickness, ham as a percent of carcass and ROP score were inferior with increases in carcass weight. Feeding system had significant effects on average daily gain, average daily feed consumption and feed conversion. Self-fed pigs had higher average daily gains and average daily feed consumption but were less efficient converters of feed to gain. Carcassses of self-fed pigs were inferior to those of limit-fed pigs in total backfat thickness, loin area, ratio of loin area to backfat thickness and ROP score.

This book was released on 1987-02-01 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: How much do animals eat? Why do eating patterns change? How do physiological, dietary, and environmental factors affect feed intake? This volume, a comprehensive overview of the latest animal feed intake research, answers these questions with detailed information about the feeding patterns of fishes, pigs, poultry, dairy cows, beef cattle, and sheep. Equations for calculating predicted feed intake are presented for each animal and are accompanied by charts, graphs, and tables.
