Book excerpt: Abstract: The study evaluated the effects of a 28 d pre-harvest ractopamine (RAC) feeding program on average daily gain (ADG), feed conversion efficiency (FC), backfat (BF) and loin muscle area (LMA), pork loin quality, and cortisol concentration in purebred Berkshire pigs (n = 117) utilizing a randomized complete block design with three treatments (Control (C), 0 ppm; RAC5, 5.0 ppm; RAC10; 10 ppm) in four replicates. Litter-mate pigs were randomly assigned to each of the three treatments within a replicate. Ultrasonic BF and LMA, pig weight, and salivary cortisol concentrations were measured at days 0, 7, 14, 21, and 28 of the feeding period. Blood was collected during harvest at exsanguination for plasma cortisol measurements. Carcass composition and pork quality (NPPC, 2000; visual color, marbling, firmness, and wetness and instrumental measures of ultimate pH and Minolta L*, a*, and b* were assessed at 24h post-harvest. Mixed model procedures of SAS were used in analyses. Fixed effects were treatment, sex, and a treatment x sex interaction, with sex and interaction effects removed if not significant (P> 0.10). Random effects included replication and litter nested within replication. Individual ADG was greater (P

Available in PDF, EPUB and Kindle. Book excerpt: After the experience of the first volume, The World Association for Animal Production (WAAP) continues the publication of the Book of the Year series for the benefit of animal scientists and policy makers in the field of livestock systems. The WAAP asked the best known and significant animal scientists in the world to contribute to the preparation of this book. Following the success of the first volume of the series, the WAAP Book of the Year 2003, many authors from the six continents are contributing to this 2nd volume. The importance of this publication is to have already established a worldwide reference for the animal science and production sectors. There are the usual four sections that raised much interest in the previous volume of the series. The first section has six articles, describing the changing conditions of livestock systems in each of the six continents. The second section has more than twenty papers, describing the development of the many sectors in which the animal science field has been divided. The third section, dealing with contemporary issues, is declared by our readers to be the most interesting. It allows participating authors to describe current and significant issues important in these last years for the animal science and production sectors. The statistics produced in the previous volume are updated and enhanced with new figures in this book to form the fourth section. The papers included in this book speak clearly of the development in the last twelve months in the livestock systems worldwide. Major space is also devoted to the list of references from where every author can start to deepen his knowledge. This book is essential for libraries that want their readers to be easily updated. Also scientists, policy makers and scientific writers, who need, to enhance their competence, to have the most practical way of knowing what is going on in the world in the field of livestock science and production will find this book of great value.
Book Synopsis Effect of Ractopamine Hydrochloride on Growth and Carcass Characteristics of Lightweight Swine by : Mark Adam Frenzel
Download or read book Effect of Ractopamine Hydrochloride on Growth and Carcass Characteristics of Lightweight Swine written by Mark Adam Frenzel and published by . This book was released on 2010 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted using 65 pigs to measure the effects of ractopamine hydrochloride (RAC) on growth and carcass characteristics of lightweight swine. Beginning weights averaged 68.23 kg. RAC was included in the diet at 0, 5, and 10 ppm for 25 days until an average weight of 92 kg. Last rib fat thickness was lower (P0.05) for the 5 ppm and 10 ppm groups. No other differences (P0.05) were found between treatment groups for growth, feed efficiency, carcass cutability, or pork quality traits. These results suggest that feeding ractopamine hydrochloride in lightweight swine diets can reduce last rib fat while not impacting growth or other carcass traits.

Book Synopsis Effects of Dietary Fiber on the Growth Performance, Carcass Characteristics, and Carcass Fat Quality in Growing-finishing Pigs by : Matthew Duane Asmus
Download or read book Effects of Dietary Fiber on the Growth Performance, Carcass Characteristics, and Carcass Fat Quality in Growing-finishing Pigs written by Matthew Duane Asmus and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments used 777 pigs to study the effects of fiber source; wheat middlings (midds), dried distillers grains with solubles (DDGS), and choice white grease (CWG), and reduction strategies for growing and finishing pigs. Also a fourth study utilizing 1,360 pigs was conducted to determine the effect of immunocastration (IC) and DDGS withdrawal on growth performance, carcass characteristics, fatty acid analysis, and iodine value (IV) of pork fat depots in growing and finishing pigs. Experiment 1 determined that the ingredient source of fiber (wheat middlings or DDGS) was more important than NDF level alone, for characterization of growth, carcass, and yield responses. Experiment 2 showed that a short (23 d) fiber reduction strategy was successful at fully recovering yield loss; however, a longer reduction (47 d) was necessary for further improvements in carcass fat quality (IV). Experiment 3 further proved that yield loss can be recovered with a short fiber reduction strategy (19 d), and that adding energy from CWG during the fiber reduction period can improve feed efficiency, but was unsuccessful at further improving carcass yield or carcass fat quality. Experiment 4 showed that carcass yield was lower for IC pigs than barrows regardless of dietary DDGS or withdrawal strategy. Also pigs fed 30% DDGS throughout had decreased carcass yield; however, withdrawing DDGS from the diet on d 74 was effective at recovering the yield loss. While DDGS withdrawal strategy was successful at lowering IV, but was unsuccessful at fully lowering IV to values of pigs fed the control diet throughout. Iodine values were somewhat variable within fat depot, showing the jowl and clear plate fat were less accurate in showing changes from the diet, most likely due to the fact they are deposited earlier and are slower to turnover. Iodine value tended to be greater for IC pigs than barrows on d 107, but by d 125 there were no differences in IV between IC and barrows. This dramatic improvement from d 107 to 125 could be caused by the dilution of unsaturated fatty acids, specifically C18:2 and C18:3, due to the rapid deposition of fat in IC pigs.

Book Synopsis Metabolic Modifiers by : National Research Council
Download or read book Metabolic Modifiers written by National Research Council and published by National Academies. This book was released on 1994-02-01 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Swine Nutrition As climate change continues to have a significant impact on the modern world, it is crucial to find alternative sources of energy and nutrients for swine production. The development of optimal feeding revolves around a multitude of considerations—genetic variations in the pig, variability, availability, and stability of nutrients in feed ingredients, interactions among nutrients and non-nutritive factors, voluntary feed intake, physical (& social) environment of pigs, and more. Establishing the ideal network of factors will only grow in importance as humans assess the methods for our own food networks. Sustainable Swine Nutrition is a comprehensive book on swine nutrition, covering some fundamental aspects of nutrition—namely digestive physiology, water, protein or amino acids, lipids, carbohydrates, energy metabolism, vitamins, minerals, and nutrition and immunology. Providing the most up-to-date information on each of these areas, a major emphasis of this second edition is on recent developments and current advances in the field, with a focus on pertinent issues linked with energy and nutrients. In doing so, the book highlights topics and issues that can contribute to the ultimate goal of successful and sustainable swine production. Sustainable Swine Nutrition readers will also find: Environmentally friendly, optimal feeding strategies for successful and sustainable swine production Recent developments, such as alternative feedstuffs, feed additives, and bioavailability Expanded treatment and new chapters on swine physiology, energy and protein, technology, and more Sustainable Swine Nutrition, Second Edition, is an ideal resource for livestock scientists and industry professionals involved in all aspects of pork production.

Book Synopsis Influence of Dietary Fiber and Copper on Growth Performance and Carcass Characteristics of Finishing Pigs and Utilizing Linear Programming to Determine Pig Flow by : Kyle Francis Coble
Download or read book Influence of Dietary Fiber and Copper on Growth Performance and Carcass Characteristics of Finishing Pigs and Utilizing Linear Programming to Determine Pig Flow written by Kyle Francis Coble and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 7,061 finishing pigs were used in 7 experiments. Experiment 1 investigated the effects of withdrawing high-fiber ingredients prior to marketing to optimize growth performance, carcass yield, and carcass fat quality. Switching pigs from a high-fiber to a low-fiber corn-soy diet approximately 15 to 19 d before slaughter restored carcass yield and partially decreased carcass fat IV compared to pigs fed the high-fiber diet until slaughter. Experiment 2 studied 30% distillers dried grains with solubles (DDGS) and 5% added fat prior to slaughter on growth performance and carcass characteristics. Adding 5% fat to finishing pig diets containing 30% DDGS approximately 20 d before slaughter improved ADG and G:F but did not overcome the reduction in carcass yield from feeding DDGS. Experiment 3 investigated the Cu source on growth performance and carcass characteristics. Increasing dietary Cu in high byproduct diets improved growth and feed intake, resulting in increased final BW and HCW for pigs fed both Cu sources. Experiment 4 examined added Cu and standardized ileal digestible (SID) lysine (Lys) level on growth performance, carcass characteristics, and carcass fat quality. Feeding 150 mg/kg Cu to pigs in the 100% SID Lys requirement diet had improved growth but in the 85 or 92.5% SID Lys requirement diet no response to added Cu was found. Furthermore, increasing SID Lys increased ADG and HCW, but added Cu did not influence growth when feeding low SID Lys. Experiment 5 investigated diet ingredient type and added Cu on growth performance, carcass characteristics, gross energy digestibility, and small intestine histology and gene expression. When comparing diet type and added Cu, pigs fed a byproduct diet with DDGS and bakery meal tended to have lower G:F and reduced HCW compared to pigs fed a corn-soy diet. Adding Cu did not influence growth or carcass characteristics. However, adding Cu to the byproduct diet improved gross energy digestibility and decreased the crypt depth in the distal small intestine. Finally, a linear programming model was developed as a decision tool for commercial swine producers to help guide pig flow decisions to maximize the return to the operation.
