Embodiment Construction

[0039] 1. Zinc oxide-Fructooligosaccharide compound sustained-release pellets

[0040]

[0041] Preparation method: mix the zinc oxide powder, fructooligosaccharide and starch described in the above-mentioned embodiment uniformly according to the prescribed dosage, and place in a mixing granulator; add hot water to make a soft material, and then squeeze, spheronize, dry, Sieving to produce zinc oxide pellets with a diameter of 0.3-0.9mm, the coating material is made into a 10% concentration aqueous suspension, and talc, sodium alginate and diethyl phthalate are added under stirring , Keep stirring; place the zinc oxide pellets in the coating machine, start the coating machine, spray coating, and make enteric-coated pellets, the diameter of the pellets is controlled between 0.3-0.9mm.

[0042] Results: The determination was carried out in artificial gastric juice and artificial intestinal juice, as follows:

[0043]

Abstract

The invention relates to a novel enteric sustained-release zinc oxide-oligosaccharide composite pellet for feed and a preparation method thereof. The novel enteric sustained-release zinc oxide-oligosaccharide composite pellet for feed comprises: by weight, 38 to 75% of zinc oxide powder, 15 to 35% of oligosaccharide, 2 to 14% of starch, 1.5 to 5.5% of cellulose acetate-phthalate, 0.05 to 0.1% of sodium alginate, 4.5 to 9.5% of talcum powder, and 0.15 to 0.5% of diethyl phthalate. The novel enteric sustained-release zinc oxide-oligosaccharide composite pellet for feed has the advantages of good effects of dissolution in the enteric canal and good treatment effects.

Description

Technical field: [0001] The invention relates to a novel zinc oxide and oligosaccharide compound enteric-coated sustained-release pellets for feed and a preparation method thereof. Adding such sustained-release pellets to feeds can not only improve the bioavailability of zinc oxide in animals, but also, The oligosaccharides in the pellets can increase the daily weight gain of animals, reduce the feed-to-weight ratio and diarrhea rate, and have good economic value. Background technique: [0002] Zinc is a component of more than 40 enzymes in the human body. It is involved in nucleic acid and protein synthesis, energy metabolism, redox and other processes. Studies have shown that an appropriate amount of zinc can effectively promote the metabolism of animals. Adding a certain dose of zinc to the feed can promote the proliferation of intestinal villi and intestinal epithelial cells of piglets, and accelerate the repair of intestinal mucosa and villi damage caused by weaning stress. ...
