Second, amino acid additives Currently, the feed mainly contains methionine, lysine and other limiting amino acid additives. 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. dXf China Feed Industry Information Network - based on feed, serving animal husbandry

Third, trace element additives For ducks, the trace elements usually need to be supplemented with copper, iron, manganese, zinc, iodine, selenium, cobalt and so on. 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 element additive produced by the additive factory is generally used, and can be added according to the instruction manual. dXf China Feed Industry Information Network - based on feed, serving animal husbandry
