Functional Feed Additives And Intestinal Health In Aquatic Animals

Aquafeed Formulation is the only resource that provides summaries with examples and formulation techniques specifically to meet the needs of anyone in the aquaculture industry. As feed is the largest single cost item in aquaculture production, and formulating aquaculture feed requires many combinations of several ingredients and nutrient requirements, this book takes a clear-and -concise approach, providing essential information on formulation and covering relevant available software, feed nutrients, and additives such as enzymes and phytase and conjugated fatty acids, as well as best industry practices to improve aquafeed production. Users will find this to be a one-stop resource for anyone interested or involved in, the global aquaculture industry. Includes the latest software evaluation for calculating protein and amino acid sources, trace minerals, and vitamins for aquaculture diets Provides essential information on formulation, covering feed nutrients and additives such as enzymes and phytase and conjugated fatty acids Presents factors affecting nutrient recommendations for aquaculture diets and nutritional effects on aquaculture nutrient excretion and water quality Covers a broad range of techniques to understand the nutrient recommendations in the NRC guide

This book offers a comprehensive collection of cutting-edge research on feed additives for a sustainable animal production, including insects and aquaculture. In five clearly structured sections, the sources of feed additives, details on their biochemistry, feed security as well as specific applications for individual farm animal species, livestock health and product characteristics (meat, milk and eggs) find attention. International expert authors provide a full description on the use of aromatic plants, extracts and essential oils as feed additives alone or in combination with functional feeds of different categories. Readers will explore the potential of feed additives to tackle environmental issues. Practical examples include the use of local feedstuffs in combination with herbal additives and enzymes. Emphasis is placed on the consequences of using local feed sources versus imported feedstuffs on global warming potential, primary energy use, nutrient excretion and the feed additive influence on lessening the pollution from animal operations. The results presented will support realization of the Sustainable Development Goals, in particular SDG 12 which stands for Responsible Consumption and Production worldwide. The use of novel and different feed additives can be an important tool to enhance sustainability, support productivity, and match increased food demands around the globe. Animal production depends on feed efficiency to sustain growth and profitability. Along these lines, the present volume is an essential reading for all future-oriented veterinarians, animal nutritionists, agricultural scientists, and moreover the feed, food and plant industry.

This book sheds light on the major functions of microbial communities in aquaculture ecosystems, showing that by recycling nutrients, degrading organic matter and preventing disease outbreaks, a variety of microbes are truly beneficial to a wide range of aquaculture industries. It discusses how deteriorating environmental quality enables some microbial strains to trigger disease, describes the development of highly sustainable tools to improve water quality, and identifies crucial factors that endanger microbial homeostasis in aquaculture ecosystems. The book also covers post-antibiotic approaches for preventing and treating opportunistic microbial infections based on harnessing environmental and fish-associated microbial communities. Furthermore, it explores how manipulating and engineering these complex microbial communities using bio-agents such as probiotics, phages, natural nutritional additives, or with fine-tuned biofilters will open the door for new ways to develop a more sustainable and cost-effective aquaculture industry. Including an accessible presentation of modern high-throughput sequencing technology to identify host-microbial interactions in aquaculture ecosystems, this book is a valuable resource for scientists, aquaculture and fishery experts, sustainability enthusiasts and scholars in the areas of biology and marine agriculture.
