Animal nutrition additive trace element compound package and its preparation method and application

Abstract

The invention discloses an animal nutrition additive trace element compound package and its preparation and application. The compound package is mainly composed of compound glycine polymineral, selenite and trace element basic salt. The compound glycine polymineral contains glycine copper, glycine Ferrous iron, zinc glycinate, manganese glycinate, etc.; trace element basic salts include at least one of the corresponding basic chloride, basic carbonate or basic sulfate of trace elements such as copper, zinc and manganese. The preparation method of the present invention comprises the following steps: mixing the raw material glycine and inorganic trace element compounds into water, adjusting the pH value, raising the temperature, fully stirring the reaction and discharging the material, and then adding other raw materials to the reaction product to prepare a uniformly dispersed mixed Suspension, and finally dried and granulated to obtain a complex package of trace elements. The trace element compound of the invention can be used as an animal feed additive, and has the advantages of simplified process, high biological potency, low addition amount, obvious growth-promoting effect, less animal side effects and the like.

Description

technical field [0001] The invention relates to the field of animal feed additives, in particular to a compound animal feed additive and its preparation method and application. Background technique [0002] With the improvement of people's living standards and the continuous development of the breeding industry, glycine, as an amino acid for feed, has been widely used in piglet feed, breeding pig feed, broiler feed, prawn feed and eel feed. The use of glycine as an animal feed additive has the following characteristics: it can be used to produce protein feed; it can be used as an attractant (attractant) in feed additives to increase animal feed intake; it can inhibit the reproduction of Bacillus subtilis and Escherichia coli, which plays an important role. Antiseptic effect, reduce the diarrhea rate of piglets caused by ration mildew. Therefore, adding glycine to animal diets maximizes feed utilization. [0003] Trace element copper can effectively participate in important...

Problems solved by technology

However, as the trace elements copper, iron, zinc, manganese and other trace elements necessary for animals, inorganic metal salts are mostly used as animal feed additives at present. Animals must pass through various biological barriers to absorb and utilize the inorganic salts. Low, large amount of addition, low biological potency, most of which will pollute the environment after being excreted in feces, and have a destructive effect on the activity of other nutrients in the feed (such as vitamins, etc.)

In addition, there are many kinds of copper, iron, zinc, manganese and other trace elements, which are easy to have antagonistic and redox reactions with each other, with other ingredients in the feed or with oxygen in the air during production, storage and transportation, and then break down. The balance of various trace elements in the diet will lead to the imbalance of nutrients, increase the burden of animal metabolism, affect the absorption and metabolism of other nutrients in animals, and then affect the health and production performance of animals. causing symptoms of poisoning in animals
