Overview
Feed-grade Minerals and Trace Elements refer to inorganic or organic compounds specifically used in animal feed to supplement and balance the mineral and trace element content of animal diets. They are essential nutrients for animals to maintain normal physiological functions, growth and development, reproductive performance, and immune health. Based on the different quantitative requirements of animals, they can be divided into two main categories:
Macrominerals: Minerals that are present in higher amounts in the animal body (accounting for more than 0.01% of body weight) and required in larger quantities, including Calcium (Ca) and Phosphorus (P), as well as magnesium, sodium, potassium, chlorine, and sulfur. Calcium and phosphorus are the main components of bones and teeth, accounting for approximately 70%–80% of the total minerals in the animal body.
Trace Elements / Microminerals: Minerals that are present in lower amounts in the animal body (accounting for less than 0.01% of body weight) but have important physiological functions, including Copper (Cu), Iron (Fe), Zinc (Zn), Manganese (Mn), Iodine (I), Selenium (Se), Cobalt (Co), etc.
Applications
Swine Feed
Swine feed is the largest application market for trace elements. In the starter phase, zinc supplementation is particularly important. Ministry of…
Poultry Feed
Poultry feed is the second largest application market for trace elements. Layers have high requirements for calcium and phosphorus, which are…
Mineral Premixes and Complete Feeds
Feed-grade minerals are typically added to feed in the form of premixes. A premix is a uniform mixture of one or more trace element compounds with…
