Problems solved by technology

In view of this, trace elements generally adopt the pretreatment method of granulation coating, but because the granulated trace element particles are ultra-fine, the granulation is slow and uneven, and the cost is high

Abstract

The invention discloses granulated and enteric coated composite trace elements and a preparation method thereof. The composite trace elements are formed by granulating and enteric coating of raw materials, and the raw materials comprise the following components in parts by weight: copper oxychloride 0.5-0.6, ferrous bisglycinate 10-11.88, zinc methionine 20-20.50, manganese sulfate monohydrate 2-2.6, 1% sodium selenite 2-2.5, 1% potassium iodate 2-2.5, diatomite 45-75, modified starch 2-10, Xanthan gum 0.5-1.6, sodium carboxymethyl cellulose 0.5-1.6, and 30% water-based enteric polyacrylic resin 10.50-12. The preparation method comprises the following steps: humidifying and mixing of the above raw materials; swinging, extruding and granulating; vortex particle shaping; enteric coating; drying and screening. The specific surface area of the trace elements is obviously reduced, the trace elements are effectively isolated from nutrients which are easily induced and oxidized in the feed, vitamins in premix and fat in concentrated feed are thoroughly prevented from being induced and oxidized by the trace elements, and the palatability of the feed products is increased. Moreover, the granulation speed is fast, the granules are uniform, and the cost of the trace elements is low.

Description

technical field [0001] The invention relates to a granulated enteric-coated composite trace element and a preparation method thereof. Background technique [0002] Composite trace elements are additive products added to premixes, concentrated feeds and complete compound feeds, and generally contain six trace elements: copper, iron, zinc, manganese, selenium, and iodine. At present, the forms of trace elements include inorganic mineral salts, amino acid chelates, EDTA chelates, and protein hydrolyzate chelates. The absorption of trace elements plays an important role in promoting the secretion of animal enzyme systems and normal growth and development of animals. . [0003] Because most of the inorganic trace elements exist in the form of sulfate and hydrochloride, which have certain moisture absorption and poor palatability, adding them to premixes and concentrated feeds will induce the oxidation of vitamins and fats, reducing animal feed intake and nutritional value of fee...
