This volume summarizes in 14 chapters the changing world of animal husbandry. The findings present the reality and facts of animal husbandry, attempting to dispel the myths circulating about this field. Animal husbandry regulation provides the necessary framework for operation and development, which is closely related to changing human needs. New opportunities are always needed to achieve planned development goals. Nutrition and the environment are closely related and influence the production method. The utilization of forest areas and extensive regions in animal production is not only a past practice, but also a present reality, influencing the future of our environment. The resilience and adaptation of animals and farms to the changing conditions play a fundamental role in maintaining sustainable animal husbandry.
