Book Synopsis The Use of Serial Ultrasound Evaluation of Body Composition Traits to Predict Performance Endpoints in Commercial Beef Cattle by : Sorrel Ann Clement
Download or read book The Use of Serial Ultrasound Evaluation of Body Composition Traits to Predict Performance Endpoints in Commercial Beef Cattle written by Sorrel Ann Clement and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bos indicus influenced primiparous heifers (n = 300) and yearling Beefmaster heifers (n = 172) were evaluated to determine relationships between serial carcass ultrasound traits and ability to breed in short (45 to 90 d) breeding seasons. Data collected included carcass ultrasound traits: ribeye area (REA), intramuscular fat (IMF), rump fat (UFAT), ribfat, weight, and body condition score taken at yearling age, pregnancy determination, before breeding, and after the breeding season when pregnancy status was recorded. A logistic regression analysis was used to determine the influence of ultrasound traits and body condition on pregnancy status. Odds ratios suggested the likelihood of primiparous cattle rebreeding would have been increased by 93% if IMF would have averaged 3.5% instead of 2.5% as yearlings, or an increase in the average ribfat as yearlings from 0.287 to 0.387 cm would have increased the odds of rebreeding by 88%. Increased average body condition score of 6.5 rather than 5.5 at 30 days postpartum in primiparous cows was estimated to have increased rebreeding 367%. The odds of yearling Beefmaster heifers successfully breeding during a 45-day season would have been increased by 73% (year 1) or 274% (year 2) by increasing REA 6.4 to 6.5 cm^2 at a year of age. Steers were serially scanned beginning at approximately 265 kg of body weight through harvest in 56 day +/- 6 intervals. Data collected included ultrasound measurements (ribeye area (REA), 12th rib fat thickness (RibFat), percent intramuscular fat (IMF), and rump fat (UFAT)), weight, and carcass data. Days to choice was calculated for each steer based on a linear regression. The IMF deposition was quantified as quadratic from scans 1-6 and linear when cattle were on full feed. Prediction models at scans 1, 2, 3, 4, 5, and 6 yielded R-square values of 0.20, 0.25, 0.41, 0.48, 0.59, and 0.49, respectively for days to choice. Odds ratios suggested that if steers in this study had averaged 3.78% at day 0 rather than 2.78, the odds of cattle grading premium choice or greater would have been increased by 300%.

Book Synopsis Equine Applied and Clinical Nutrition E-Book by : Raymond J. Geor
Download or read book Equine Applied and Clinical Nutrition E-Book written by Raymond J. Geor and published by Elsevier Health Sciences. This book was released on 2013-01-31 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equine Applied and Clinical Nutrition is a comprehensive text resource on the nutrition and feeding management of horses. Over 20 experts from around the world share their wisdom on a topic of central relevance to all equine practitioners and the equine community generally. Both basic and applied (including healthy and diseased animals) nutrition and feeding management of horses and other equids (i.e. ponies, donkeys, wild equids) are covered. The book will appeal to a wide audienc: undergraduate and post-graduate students in equine science and veterinary medicine, veterinarians, equine nutritionists, horse trainers and owners. The clinical component will strengthen the appeal for equine veterinarians. Equine Applied and Clinical Nutrition will be a "must have" for anyone involved in the care of horses, ponies and other equids. The book is divided into 3 parts: Basic or core nutrition in this context refers to digestive physiology of the horse and the principles of nutrition. Applied nutrition deals with the particular types of foods, and how to maintain an optimum diet through various life stages of the horse. You might characterize this aspect as prevention of disease through diet. Clinical nutrition covers various diseases induced by poor diet, and their dietary treatment and management. It also looks at specific feeding regimes useful in cases disease not specifically induced by diet. Authoritative, international contributions Strong coverage of clinical aspects either omitted from or only sparsely dealt with elsewhere Full colour throughout The only clinical equine nutrition book

Book Synopsis Nutrient Requirements of Beef Cattle by : Subcommittee on Beef Cattle Nutrition
Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Download or read book Handbook on Experimental Economics and the Environment written by John A. List and published by Edward Elgar Publishing. This book was released on 2013-01-01 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Until not much more than 20 years ago, economists frequently lamented the fact that they were limited in their empirical analyses to statistical assessments of market behavior, because controlled economic experiments were (thought to be) infeasible, unethical, or both. Much has changed in the intervening years! In this new volume, John List, Michael Price, and their co-authors provide a diverse set of applications of experimental approaches to the environmental economics realm. This is among the most promising of new areas of research in the economics of the environment, and this book provides a superb point of entry for experts and novices alike.' – Robert Stavins, Harvard University, US Laboratory and field experiments have grown significantly in prominence over the past decade. The experimental method provides randomization in key variables therefore permitting a deeper understanding of important economic phenomena. This path-breaking volume provides a valuable collection of experimental work within the area of environmental and resource economics and showcases how laboratory and field experiments can be used for both positive and normative purposes. The Handbook provides a timely reminder to social scientists, policymakers, international bodies, and practitioners that appropriate decision-making relies on immediate and sharp feedback, both of which are key features of proper experimentation. This book includes a collection of research that makes use of the experimental method to explore key issues within environmental and resource economics that will prove invaluable for both students and academics working in these areas.
