First, the use of vitamin additives Vitamin supplements, in addition to feeding standards, but also should consider feeding methods, environmental conditions, duck meat and other constitution. Vitamin additives have a single vitamin additive and multidimensional additives.
Second, amino acid additives At present, there are mainly limited amino acid additives such as methionine and lysine. When the protein content in the diet is low, the effect is more obvious. The effect is to achieve the best ratio of amino acids in the duck diet, reduce the amount of animal protein feed, and improve the utilization of duck protein feed.
Third, trace element additives For ducks, the trace elements that usually need to be supplemented are copper, iron, manganese, zinc, iodine, selenium, and cobalt. Sulfate is generally used as a raw material for trace element additives such as copper sulfate, ferrous sulfate, zinc sulfate, manganese sulfate, and iodine and selenium can be obtained from potassium iodide and sodium selenite. In the production, the trace additive additives produced by the additive plant are generally used and added according to the instruction manual.
