Available in PDF, EPUB and Kindle. Book excerpt: Symptoms were identified in channel catfish fed diets deficient in the water-soluble vitamins pyridoxine, pantothenic acid. riboflavin, thiamine, folic acid, nicotinic acid, B-12, or Choline. Fat-soluble vitamin A and vitamin K deficiency systems were observed after feeding diets which contained beta-carotene and 4.0 milligrams of menadione (synthetic vitamin K) per 100 grams of food (dry weight). These deficiencies were eliminated by substituting vitamin A palmitate for beta-carotene and doubling the content of menadione. No dietary need was observed for the water-soluble vitamins biotin, inositol, ascorbic acid, and para-aminobenzoic acid.

Download or read book Dietary Nutrients Additives and Fish Health written by Cheng-Sheng Lee and published by John Wiley & Sons. This book was released on 2015-06-22 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

Book excerpt: Using the latest research in fish nutrition, this volume revises and combines the 1981 edition on coldwater fish and the 1983 edition on warmwater fish and shellfish. In addition to updating requirements for energy, protein, minerals, and vitamins, this book provides, for the first time, summary tables on nutrient requirements of a variety of fish species, including channel catfish, rainbow trout, Pacific salmon, carp, and tilapia. Tabular data on amino acid requirements of 11 species are also included. Shellfish are not included in this edition because of lack of scientific information.

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.

Download or read book Role of Dietary Ingredients on Fish Performance and Genes Associated with Appetite Growth Metabolism and Intestinal Inflammation in Channel Catfish Ictalurus Punctatus written by Julie C. Schroeter and published by . This book was released on 2015 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: In commercial channel catfish production, feed costs are the largest variable expense. In recent years, the use of fishmeal in catfish feeds has raised sustainability and cost concerns, and as such, a notable amount of research has been dedicated to the exploration of alternatively-sourced ingredients for use in channel catfish diets. The present research evaluated the effects of alternatively-sourced dietary ingredients on production indices, gut health, and genes involved in the regulation of appetite, growth, metabolism, and intestinal inflammation. In Objective 1, 45 sets of oligo primers were designed based on sequences in the Genbank database. PCR products from primers designed using teleost sequences outside of the genus Ictaluridae were cloned, transformed, and sequenced to verify gene identity. The entire set of designed primers was then validated for use in real-time PCR and used to validate a high-throughput, microfluidic, dynamic, qPCR array for measuring gene expression in the previously mentioned pathways. Thresholds for efficiency were set at R2 ? 0.9 and 0.65 for quality, using a baseline correction and auto detectors for the Ct threshold method. Of the 45 genes analyzed using a Fluidigm qPCR System, eigth genes failed due to early or late amplification, low PCR efficiency, or a low quality score. Of the potential reference genes evaluated, ?-tubulin had the highest PCR efficiency (0.9989), a high quality score (0.92±0.03) acceptable Ct values. Based these results, 40 genes from four tissues (hypothalamus/pituitary, liver, stomach, proximal intestine) were evaluated in Objective 2 in response to three alternative dietary treatments, relative to a control diet, using the Fluidigm qPCR System. Changes in dietary formulations were primarily based on alternative protein feedstuffs, with the following feedstuffs as the distinguishing protein sources: (A) fish meal (control), (B) porcine meat and bone meal, (C) soybean meal, and (D) corn germ meal/cottonseed meal. All diets were isonitrogenous and isolipidic. Dietary treatments were fed to three tanks of 20 channel catfish each for a duration of 12 weeks. Differences in feed conversion ratio (FCR), specific growth rate, feed intake, body condition, weight gain, proximal intestine histology, and quantitative gene expression were analyzed. FCR was significantly (P

Available in PDF, EPUB and Kindle. Book excerpt: "This book deals with trace elements, such as cobalt, copper, iron, manganese, selenium and zinc which are essential to modern animal nutrition, but are increasingly detrimental to soil and water quality in today's globalized production. The goal in finding a sustainable balance between trace element use in animal nutrition and its impact on the environment is addressed by focussing on the following questions: - What is the trace element flow on farm, regional or national scale and which tools are available to influence the flow? - What are today's and future soil and water quality in regards to trace minerals? - What are the trace mineral loading limits in soil and water from a health and legal standpoint? - Which technologies exist to modify slurry trace element contents? - What is today's knowledge on quantitative and qualitative trace element requirements and recommended supplementation for ruminants, swine, poultry, fish and crustaceans? - What is trace element bioavailability and how can it be determined? - To which extent are trace minerals related to immune response? - What are the future issues to be addressed in trace element nutrition? This book contains the peer-reviewed papers of the first International Symposium on Trace Elements in Animal Production Systems. It is a valuable resource for researchers and professionals in the life sciences of animal nutrition, soil and water quality, for actors in the feed industry and policy making."
