Feed additives are non-nutritive substances, preparations and micro-organisms that are added to feed to animal feeds to improve growth performance, feed intake and the efficiency of feed utilization for healthy, economic and eco-friendly livestock production. This book on Advances in Animal Feed Additives addresses current information on the use of different animal feed additives with regard to production, health and reproduction of livestock and poultry. This book contains twenty five s contributed by 30 eminent scientists of animal nutrition, which highlights the significance of antioxidants, enzymes, probiotics, prebiotics, synbiotics, antimicrobials, organic acids, coccidiostats, mycotoxin binders, immunomodulator, hen egg antibody, hormones, beta agonist, methane inhibitors, defaunating agents, essential oil and herbal feed additives. etc. for sustainable livestock and poultry production. Each of the book attempts at providing clear and updated information on feed additives supported with good amount of the experimental evidence and references which will enable the students and research workers to obtain information quickly when necessary. The book is useful to students of animal sciences, teachers and scientists of animal nutrition discipline, personnel of feed industry, field veterinarians, animal husbandry extension workers and progressive animal farmers.

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.

The production and the use of feed additives influence the environmental impact of livestock production. The use of feed additives significantly acts on feed efficiency, and thus animal and environmental performance. The methodology developed in these guidelines aims to introduce a harmonized international approach to the assessment of the environmental performance of feed additives in livestock supply chains taking into consideration the impact of their production and use all along the supply chain for large ruminants, pigs and poultry. The objective of this technical document is twofold: on the one hand, to provide detailed guidance on how to measure the environmental performance of the production of feed additives, and on the other hand, how to measure the effects of feed additives on the environmental performance of livestock products. The guidelines on the environmental performance of feed additives in livestock supply chains are intended to be used with other published LEAP guidelines.

This Special Issue presents high-quality research papers as well as review articles addressing recent advances in the use of marine bioactives in animal nutrition. The marine environment constitutes a relatively untapped source of biologically active compounds that can be applied in various areas, such as improvement of animal performance, health maintenance, and disease prevention. Numerous marine-based compounds isolated from marine organisms (especially seaweeds) have diverse biological activities, including antioxidative, anti-inflammatory, antibacterial, antifungal, and antiviral activities that can be beneficial to animal health. Additionally, the application of marine bioactives as feed additives can increase the nutritional value of products of animal origin. In this Special Issue, the main attention was focused on seaweeds and their application in poultry (laying hen and broiler chickens) and pig feed. The suitable processing of marine resources required for their optimal use as feed/feed additives was underlined. The contained publications present scientific evidence for the use of various seaweeds as feed additives that improve health (enhanced immunity, prebiotic effect), growth performance, and production. Inclusion of this unconventional material in animal nutrition can enrich products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids, and pigments which are beneficial for consumers.

The production of animal feed increasingly relies on the global acquisition of feed material, increasing the risk of chemical and microbiological contaminants being transferred into food-producing animals. Animal feed contamination provides a comprehensive overview of recent research into animal feed contaminants and their negative effects on both animal and human health.Part one focuses on the contamination of feeds and fodder by microorganisms and animal by-products. Analysis of contamination by persistent organic pollutants and toxic metals follows in part two, before the problem of natural toxins is considered in part three. Veterinary medicinal products as contaminants are explored in part four, along with a discussion of the use of antimicrobials in animal feed. Part five goes on to highlight the risk from emerging technologies. Finally, part six explores feed safety and quality management by considering the safe supply and management of animal feed, the process of sampling for contaminant analysis, and the GMP+ feed safety assurance scheme.With its distinguished editor and international team of expert contributors, Animal feed contamination is an indispensable reference work for all those responsible for food safety control in the food and feed industries, as well as a key source for researchers in this area. - Provides a comprehensive review of research into animal feed contaminants and their negative effects on both animal and human health - Examines the contamination of feeds and fodder by microorganisms and animal by-products - Analyses contamination by persistant organic pollutants, toxic metals and natural toxins
