Problems solved by technology

[0002] With the development of intensive production in the pig industry and the improvement of the genetic potential of piglet growth rate and meat production rate, in order to meet the high demand for trace elements in piglets in factory farming, iron and copper as trace elements , manganese, zinc, iodine, selenium and cobalt are added more and more, and most of them are added in the form of inorganic salts; the trace elements added in the inorganic state in the diet cannot meet the needs of animals, more minerals Substances are excreted from the body, causing environmental pollution
[0003] In the traditional formula of trace element premixed feed for piglets, the main source of each element is inorganic salt of sulfate, which has problems such as low absorption and utilization rate and great environmental pollution; especially in recent years, the pig industry adopts high doses of oxidative The control of piglet diarrhea by zinc not only affects the absorption of other trace elements, but also affects the growth rate of piglets in the later stage
[0004] In the preparation process of the traditional trace element premixed feed, the addition of very small amounts of iodine and cobalt has the problems of poor fluidity and uneven mixing

Abstract

The invention discloses trace element premixed feed for piglets and a preparation method of the premixed feed. According to reasonable use of trace element components in the feed disclosed by the invention, the diarrhea ratio of the piglets is reduced, and pollution to the environment and soil is reduced; basic zinc sulfate and basic chrome sulfate are subjected to moisture-proof agglomeration treatment, dampening of the feed is well avoided, and due to the addition of amino acid chelate manganese, amino acid chelate iron, amino acid chelate zinc and amino acid chelate calcium, the absorption rate of the pigs on manganese, iron, zinc and calcium is improved, and due to the addition of lysine, the utilization rate of nitrogen in the feed can be effectively improved, so that the nitrogen excretion in the pig manure is reduced; protein germanium serves as a trace element germanium source additive in animal feed, so that the biological activity of the germanium trace element can be improved, the germanium element is easily absorbed, the animal growth can be effectively promoted, and the body immunity of the animal is improved; and moreover, phytase is added into the feed, and the phosphorus excretion in the pig manure is reduced.
