​​​​​​​Due to the fact that most of the regions of Iran are located in arid and semi-arid areas and the lack of fodder in some seasons, as well as the occurrence of various environmental stresses and diseases, the growth and production performance of many sheep farms in Iran is not favorable. . One of the ways to improve feed efficiency and consequently livestock production is to use low consumption elements as metabolic improving factors.

Livestock feed supplement

Poultry feed supplement

In order to survive, reproduce, produce economic meat and eggs, in addition to the need for carbohydrates, breeders, and health, poultry also need other nutrients that are fed in small amounts, which contain vitamins and minerals. In developed  and undeveloped contries, the poultry industry is the most successful unit in the agricultural sector because it quickly adapts to new technologies.

Food supplements (dietary or nutritional supplements) are produced with the aim of providing substances that are not received in sufficient amounts from food. These supplements have different types and include vitamins, minerals, medicinal 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 the mineral elements needed by the body has decreased, and the lack of these elements must be provided by giving a balanced concentrate.
