Organic Feed Additives for Livestock

Feed additives (natural or synthetic) are formulations added to livestock rations to improve growth rates, reproductive and productive traits, feed efficiency, ruminal fermentation profiles, methane mitigation, digestion and absorption of nutrients, immunity, and overall health of the animal. Organic Feed Additives for Livestock will focus on the beneficial effects of organic feed additives and on food animals, including ruminants, poultry, fish, and more. It will also explore how these feed additives can benefit food animal production, reproduction, and health. Each chapter will cover the significance of an organic feed supplement, especially as an alternative to synthetic growth promoters, with topics including medicinal plants, cold pressed and essential oils, natural antioxidants, emulsifiers, acidifiers and organic acids, fibrolytic enzymes, organic minerals, probiotics, macro- and microalgae, organic nanoparticles, yeast and its derivatives, and bee pollen.
Contributed by a range of livestock and aquaculture specialists from around the world, this book takes a holistic approach to explore how organic additives offer an efficient strategy to improve livestock productivity and health. This reference is an excellent resource for researchers and graduate students interested in animal agriculture, as well as veterinarians, animal nutritionists and breeders, and other livestock specialists. It will allow experts to stay up to date on organic options for livestock and serve as a starting point in generating new research ideas.
