Today, nutraceuticals are widely recognized as natural products, food items, or dietary supplements that provide medical or health benefits, including disease prevention. With these aspects in mind, the book covers various types of nutraceuticals used in livestock and poultry, their applications, advantages, and disadvantages, if any. Chapter 1 discusses the concepts and classification of feeding nutraceuticals into several groups. Chapter 2 focuses on the replacement of antibiotics in poultry and livestock feed with nutraceuticals, specifically feed additives. Chapters 3 to 8 provide detailed information on different nutraceuticals commonly fed to poultry and livestock, such as probiotics, prebiotics, enzymes, organic acids, fatty acids, and phytobiotics. These chapters introduce and classify the corresponding nutraceutical agents, followed by a detailed discussion of their efficacy as feed ingredients, mode of action, and specific rates of inclusion in the diet.
