Book Synopsis The Nutritive Interrelationships of Tallow and Urea in Ruminants by : Ralph L. Phillips
Download or read book The Nutritive Interrelationships of Tallow and Urea in Ruminants written by Ralph L. Phillips and published by . This book was released on 1973 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this study was to observe the effect of tallow plus urea in vitro and in vivo. The study was carried out in three parts; an in vitro fermentation study, a metabolism trial and a feedlot trial. The in vitro study was conducted using a 4 x 2 x 2 factorial design with readily available carbohydrate (RAC) levels of 30, 40, 50 and 60%; tallow levels of 0 and 3%; and urea levels of 0 and 2%. Pure cellulose or soluble starch was used to dilute or fortify the basal substrate to obtain the desired level of RAC. Treatment substrates were fermented for 18 hr. and acetic, propionic and butyric acid production and ammonia disappearance were measured. Acetic and propionic acid production and ammonia disappearance increased as the level of RAC increased from 30 to 50%. Tallow reduced acetic acid production and ammonia disappearance while increasing propionic acid production. Urea increased volatile fatty acid (VFA) production and ammonia disappearance. There was a tallow x urea interaction for acetic, propionic and butyric acids and gross energy available from VFA's as well as for ammonia disappearance. The interaction resulted in a decrease in response for all parameters except propionic acid when tallow and urea were added simultaneously. The metabolism studies consisted of four separate experiments. Trial one had the following treatments: basal, 5% tallow, 1. 5% urea, and 5% tallow + 1.5% urea. Trial two had the following treatments: basal; 3% tallow + 1.5% urea; and 5% tallow + 1.5% urea, The treatments for trial three were 5% tallow + cottonseed meal; 5% tallow + biuret; and 5% tallow + urea. Trial four had the following treatments: 5% tallow + 1. 15% urea; 5% tallow + 1.50% urea; and 5% tallow + 2.17% urea. Twelve crossbred yearling wethers were used in each trial. After a 10-day adjustment period urine and feces were collected for 10 days. Initial and final blood samples were taken to measure changes in plasma urea and total plasma lipid. Trial 1 indicated that tallow or tallow plus urea increased crude protein digestion and nitrogen retention. When nitrogen retention was expressed as a percent of dietary nitrogen retained, there were no treatment effects. The addition of tallow to the rations improved fat digestibility. Tallow or tallow plus urea increased plasma urea values. Trial 2 indicated that the addition of urea increased crude protein digestibility and nitrogen retention. Lambs receiving 3% tallow plus urea retained more nitrogen than lambs receiving 5% tallow plus urea. Trial 3 indicated that 5% tallow plus cottonseed meal reduced dry matter and crude protein digestion as well as nitrogen retention. Trial 4 showed that 1.5% urea plus 5% tallow increased dry matter digestion. There was no difference in crude protein digestibility between the three groups. In all four trials urea had no effect on total plasma lipid. The relationship between tallow and urea was studied in a feedlot trial. Twenty steers averaging 282 kg were divided into four groups and fed one of the following rations for 126 days; basal (I); basal + 1.5% tallow (II); basal + 0.75% urea (III); and basal + 1.5% tallow + 0. 75% urea (IV). The basal ration was made up of 10.5% alfalfa pellets, 34.5% barley, 20.0% oats, 9. 0% wheat, 17.5% beet pulp, 7.5% molasses and 1.0% vitamin-mineral-antibiotic premix. Blood samples were taken via jugular puncture 6 hr after the morning feeding on days 0, 14, 42, 70, 98 and 126 and plasma urea and total plasma lipid was measured. Average daily gain (kg) for the groups were: I, 1.13; II, 1.25; III, 1.44 and IV, 1.38. Group IV was the least efficient in the conversion of digestible energy and digestible protein into gain. After 14 days groups III and IV had higher plasma urea values than groups I and II. Steers in group IV had the highest total lipid values after 126 days.

Book Synopsis Nutrition and Feeding of Fish by : Tom Lovell
Download or read book Nutrition and Feeding of Fish written by Tom Lovell and published by Springer Science & Business Media. This book was released on 1998-11-30 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.
Book Synopsis Fundamentals of Dairy Chemistry by : Noble P. Wong
Download or read book Fundamentals of Dairy Chemistry written by Noble P. Wong and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Dairy Chemistry has always been a reference text which has attempted to provide a complete treatise on the chemistry of milk and the relevant research. The third edition carries on in that format which has proved successful over four previous editions (Fun damentals of Dairy Science 1928, 1935 and Fundamentals of Dairy Chemistry 1965, 1974). Not only is the material brought up-to-date, indeed several chapters have been completely re-written, but attempts have been made to streamline this edition. In view of the plethora of research related to dairy chemistry, authors were asked to reduce the number of references by eliminating the early, less significant ones. In addition, two chapters have been replaced with subjects which we felt deserved attention: "Nutritive Value of Dairy Foods" and "Chemistry of Processing. " Since our society is now more attuned to the quality of the food it consumes and the processes necessary to preserve that quality, the addition of these topics seemed justified. This does not minimize the importance of the information in the deleted chapters, "Vitamins of Milk" and "Frozen Dairy Products. " Some of the mate rial in these previous chapters has been incorporated into the new chapters; furthermore, the information in these chapters is available in the second edition, as a reprint from ADSA (Vitamins in Milk and Milk Products, November 1965) or in the many texts on ice cream manufac ture.
Book Synopsis Phytoestrogens in foods on the Nordic market by : Linus Carlsson Forslund
Download or read book Phytoestrogens in foods on the Nordic market written by Linus Carlsson Forslund and published by Nordic Council of Ministers. This book was released on 2017-08-30 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoestrogens are plant-derived compounds that may bind to estrogen receptors, but with less affinity than the natural ligand estradiol. They may be biologically active as such or after metabolization in our body. To investigate the occurrence and level of phytoestrogens, scientific literature was screened for data on isoflavones, lignans, stilbenes and coumestans in raw and processed foods of plant origin. The review presents data based both on analytical methods hydrolysing glucosides and non-destructive methods.Many phytoestrogens are phytoalexins. Their production is induced when plants are exposed to abiotic and/or biotic stress. This could explain the rather different levels reported in plants by various investigators, and indicates that many samples are required to describe the levels generally occurring in foodstuffs. The influence of food processing was also considered.
Book Synopsis Reproductive Sciences in Animal Conservation by : Pierre Comizzoli
Download or read book Reproductive Sciences in Animal Conservation written by Pierre Comizzoli and published by Springer Nature. This book was released on 2019-08-30 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences. Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.
Book Synopsis Nutrient Requirements of Fish and Shrimp by : National Research Council
Download or read book Nutrient Requirements of Fish and Shrimp written by National Research Council and published by National Academies Press. This book was released on 2011-05-25 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.
Book Synopsis Toxicological Chemistry and Biochemistry, Third Edition by : Stanley E. Manahan
Download or read book Toxicological Chemistry and Biochemistry, Third Edition written by Stanley E. Manahan and published by CRC Press. This book was released on 2002-09-25 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book bridges the gap between toxicology and chemistry at a level understandable by a wide spectrum of readers with various interests and a broad range of backgrounds in chemistry, biochemistry, and toxicology. The third edition has been thoroughly updated and expanded to reflect recent advances in important areas of research, including toxicogenetics and toxic effects on various body systems. Toxicological Chemistry and Biochemistry, Third Edition begins by outlining the basic concepts of general chemistry, organic chemistry, and biochemistry needed to understand the topics in the book. The author then presents an overview of environmental chemistry so that you can understand the remainder of the material covered within that framework. He also discusses biodegradation, bioaccumulation, and biochemical processes that occur in water and soil. The new chapter on toxic effects considers toxicities to the endocrine and reproductive systems, and the section on xenobiotics analysis deals with the determination of toxicants and their metabolites in blood and other biological materials. The chapter on the genetic aspects of toxicology discusses the ways in which chemical damage to DNA can cause mutations, cancer, and other toxic effects on specific body systems, and it considers the role of genetics in determining individual susceptibilities to various toxicants. Toxicological Chemistry and Biochemistry, Third Edition retains the basic information and structure that made the first two editions popular with students and industry professionals, while enhancing the usefulness of the book and modernizing it in important areas. Review questions and supplementary references at the end of each chapter round out the third edition of this bestselling work.
Book Synopsis Metabolic and Endocrine Physiology, Third Edition by : Larry Engelking
Download or read book Metabolic and Endocrine Physiology, Third Edition written by Larry Engelking and published by CRC Press. This book was released on 2012-08-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to give readers a “quick look” at metabolic and endocrine physiology. Emphasis is placed on instructional figures, flow diagrams and tables, while text material has been held to a minimum. In general, the endocrine system is first defined and described, and then each endocrine gland is discussed separately. Where appropriate, common endocrine disorders have also been included. This text concisely elucidates the endocrine mechanisms responsible for maintaining homeostatic control of important physiologic variables, and to assist the reader in understanding common pathophysiologic deviations from normal. Over 360 multiple-choice questions gauge the reader’s capacity to effectively understand the subject material. This new edition contains six new chapters covering: hormone disposition, measurement and secretion; bovine, equine and rodent estrus cycles; primate menstrual cycle; male reproductive system; testosterone, estrogen and progesterone; comparative aspects of endocrinology. Learning objectives have been added at the beginning of each chapter and all of the questions are new.
Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1985-03 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Download or read book Yeast technology written by Gerald Reed and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they playa key role in the conversion of sugars to alcohol and carbon dioxide. Early humans had no concept of either microorganisms or fermentation, yet the earliest historical records indicate that by 6000 B. C. they knew how to make bread, beer, and wine. Earliest humans were foragers who col lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Crushed fruits readily undergo natural fermentation by indigenous yeasts, and moist seeds germinate and develop amylases that produce fermentable sugars. Honey, the first con centrated sweet known to humans, also spontaneously ferments to alcohol if it is by chance diluted with rainwater. Thus, yeasts and other microbes have had a long history of 2 to 3.
