Book Synopsis Aquatic Animal Nutrition by : Christian E.W. Steinberg
Download or read book Aquatic Animal Nutrition written by Christian E.W. Steinberg and published by Springer Nature. This book was released on 2022-01-03 with total page 1082 pages. Available in PDF, EPUB and Kindle. Book excerpt: As sequel to Aquatic Animal Nutrition – A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition – Organic Macro and Micro Nutrients addresses several gaps in nutritional research and practice. One major gap is the lack of common research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aquatic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel genetic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To increase public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.

Book excerpt: Incorporating research chapters from academic authors around the world, this book focuses on the most recent scientific advances in understanding phytate; both IP6 and its esters. It examines phytate degradation patterns in the gastrointestinal tract, and investigates the relevance of gut microbiome and endogenous phosphatases on phytate breakdown, as well as regulation and functions of inositol diphosphates IP3, IP4, and IP7, IP8. It also identifies recommendations for formulating for minerals and amino acids in the presence of phytate, including the effects of phytase on protein bioavailability, and the impact of digestible Ca and P in both swine and poultry. This leading science and research is coupled with real-world pragmatism, including a focus on what industry stakeholders are currently doing to counter dietary phytate, and an overview of the role of nutrition in respect of bone health, meat quality, welfare, and antibiotic free production. As such, the content is relevant for scientists, nutritionists and producers alike.
Book Synopsis Alternative Protein Sources in Aquaculture Diets by : Chhorn Lim
Download or read book Alternative Protein Sources in Aquaculture Diets written by Chhorn Lim and published by CRC Press. This book was released on 2023-05-09 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique resource that describes the ingredients included in an aquaculture diet, species profiles, processing methods, impacts to environment and industry, and more. Aquaculture is and will remain a major food producing sector in the future. To become more efficient and successful in the aquaculture industry, operations need to provide good nutrition. Alternative Protein Sources in Aquaculture Diets is a unique source describing the ingredients included in fish and crustacean diets, their nutrient compositions, species profiles, suitability for species, processing methods, and impacts of alternative ingredients on the environment and to the aquaculture industry. World-renowned nutritionists and feed technologists explore practical ways for the aquaculture industry to expand and remain competitive, and discuss ways to develop less expensive alternative sources or protein. Diet costs take up a huge chunk of operating expenditures, with fish meal being one of the most expensive ingredients in the aquaculture diet. Alternative Protein Sources in Aquaculture Diets provides detailed knowledge on the use of alternative plant and animal protein sources, offering opportunities to either partially or completely replace fish meal. This comprehensive, up-to-date text discusses the most widely used ingredients as well as various previously under-utilized ingredients which could be of significant potential in the future. The book is extensively referenced and includes numerous helpful tables to clearly present data. Topics discussed in Alternative Protein Sources in Aquaculture Diets (for finfish and crustacean species) include: • farmed fish diet requirements • reduction of waste through diet formulation • poultry by-product meal • meat packing by-products • soybean protein foodstuffs • cottonseed meal • lupins • unconventional plant protein supplements.

Book Synopsis An Investigation of Factors that Affect the Efficiency of Limiting Amino Acid Utilization by Rainbow Trout (Oncorhynchus Mykiss). by : Afshin Gholami
Download or read book An Investigation of Factors that Affect the Efficiency of Limiting Amino Acid Utilization by Rainbow Trout (Oncorhynchus Mykiss). written by Afshin Gholami and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn gluten meal (CGM) is a high protein ingredient commonly used in fish feeds. However, studies suggest that diets containing high levels of CGM elicit lower voluntary feed intake, growth and lower efficiency of utilization of limiting amino acid (AA) compared to other protein sources. It has been hypothesized that the AA profile of CGM (low lysine, excess leucine) could be responsible for these effects or protein from CGM could be digested faster than other protein sources, resulting in faster absorption and less efficient utilization of its AAs. A series of studies were conducted to examine the effect of feeding CGM on growth, efficiency of lysine utilization and the dynamics of protein digestion in rainbow trout. Results of growth trial indicated that weight gain, FE and nitrogen retention efficiency were significantly lower in fish fed CGM-based diets compared to those fed WGM based diets. Digestibility trial results revealed lower apparent digestibility of crude protein in CGM-based diets compared to that of WGM-based diets. The efficiency of digestible lysine utilization did not differ between the CGM and WGM-based diets. Serial digesta sampling of the gastrointestinal (GI) tract of rainbow trout and blood sampling were carried out to estimate digesta transit time and plasma AA concentrations. Results indicate that CGM-based diets passed through the GI tract four times faster than WGM-based diets. The ratios of plasma leucine to branched-chain amino acids, and leucine to lysine, were generally higher, for fish fed CGM-based diets compared to those fed WGM-based diets. To examine the impact of the excess leucine on growth performance and efficiency of AA utilization, rainbow trout were pair-fed CGM or WGM-based diets formulated to be deficient in lysine and contain adequate and excess leucine levels. Results indicated that excess leucine did not affect growth and efficiency of lysine utilization. The results from this thesis suggest that the lower digestibility of protein and AAs of CGM may in part explain the lower performance of CGM-based diet compared to other protein sources in some studies. Differences in the dynamics of digestion and absorption of AAs and their appearance in the circulation are evident. Therefore, it should be examined further in future studies.

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.
