Production of healthy feed for livestock and poultry has a direct relationship with human food health. The role of the livestock and poultry industry as an active part among the agricultural and animal husbandry industries in all parts of the world is quite tangible, and the importance of the quality of the products of this industry in the human food cycle is also undeniable, and any negligence in the production of healthy feed for livestock and poultry causes Human food health will be endangered, we are going to say something about  Food supplements (dietary or nutritional supplements) are produced with the aim of providing substances that are not received in sufficient amounts of food. These supplements have different types and include vitamins, minerals, hearbel plants, proteins, etc The type and amount of minerals in livestock and poultry feed are naturally supplied from plant sources and have a direct relationship with the age and climate of plants, and depending on the type of livestock and poultry feed, its type and amount also vary. Due to the lack of feeding the livestock with fresh and young plants, especially in the cold seasons of the year, as well as the lack of land rich in all the elements needed by the body, the concentration of mineral elements needed by the body has decreased, and the lack of these elements should be provided by giving a balanced concentrate.

One of the ways to improve feed efficiency and consequently livestock production is using of low consumption elements as metabolic improving factors.
