What are the methods for supplementing mineral elements in cattle and sheep?

①Supplement together with mixed concentrate, which is the main form of mineral element supplementation for cattle and sheep. Cattle and sheep fattening generally requires supplementary feeding of mixed concentrate, and mineral elements can be supplemented together with the mixed concentrate, which is convenient to use, but care must be taken to mix evenly, especially for those elements with a narrow range between the safe amount and the toxic amount, such as selenium, so as not to cause adverse effects on cattle and sheep from consuming excessive mineral elements. For cattle and sheep that graze and are usually rarely supplemented with concentrate, this method is generally not used.

②Prepare macro-element and trace-element premixes separately, allowing cattle and sheep to lick freely according to their own needs. The disadvantage of this method is that it is inconvenient to use, and in addition the waste is relatively large.

③Make lick blocks for cattle and sheep to lick. Lick blocks are designed according to the formula of nutritionists, fully mixing together all the mineral elements essential to livestock, including salt, and then pressing them under high pressure into block-shaped products of a certain strength. Livestock can lick these block-shaped products at will according to their own needs, and they are very convenient and safe to use. For cattle and sheep that mainly graze and are usually rarely supplemented with mixed concentrate, this is a very good way to supplement mineral elements.
