Cheptel Feed additives are defined as products used in animal nutrition for purposes of improving the quality of feed and the quality of food from animal origin, or to improve the animals’ performance and health, e.g. providing enhanced digestibility of the feed materials. These are the single substances that are added to feed in micro quantities to fulfill a specific function, such as to aid digestion, for weight gain, to stimulate appetite, etc in animals. They are also called as dietary ingredients incorporated in feed formulations not only for the usual provision of basic nutritional requirements as offered by traditional feed but also for growth and health enhancement and environmental and economic gain.
