Problems solved by technology

However, because most of the aquatic feed additive drugs are released in water bodies, some water-soluble additives are easy to dissolve, diffuse and lose, resulting in a decrease in effective concentration, which is not only inefficient, but also pollutes the water environment. It is imminent to add premix and fish medicine

Embodiment 1

[0019] Embodiment 1, vitamin C coating premix granule

[0020] 1. First, take a certain amount of vitamin C and granulate the raw material in the known manner as above, and then wrap it by rolling coating method.

[0021] 2. Preparation of coating solution: Weigh 600 grams of acrylic resin IV and dissolve in 20 liters of 95% ethanol to make a resin solution. Take 250 grams each of titanium dioxide, talcum powder, and magnesium stearate, mix well, add to the above resin solution and grind 100-mesh sieve, then add 95% ethanol to a certain amount, stir well, and set aside.

[0022] Corn protein solution preparation: get corn protein 1000g and add 15 liters of solvents of 95% ethanol, then add 200g stearic acid to dissolve (hot water can be used to help dissolve if necessary), finally add phthalic acid diethyl alcohol 250ml, stir evenly.

[0023] 3. Spraying process: adjust the position, angle and distance of the spray gun of the sugar coating machine. Preheat the sugar coating ...

Abstract

This invention relates to high molecular material encapsulated aquatic product feed supplement. The feed supplement comprises wrappage, membrane wrapped on the surface of the wrappage at least adopting a natural or synthetic polymer material such as high molecular polymer; and obtained by wrapping the wrappage with 1-25wt.% high molecular polymer solution or suspension to microencapsulating the raw material. The high molecular polymer at least comprises one or two of chitosan, sodium alginate, polyacrylic resin, and zein. The invention can form firm, esthetic stable membrane layer without toxity and side effect on the wrappage surface. The product of the invention is insoluble or indissolvable in fresh water or seawater, can only dissolve in acid digestive juice of aquatic animal, control release and dissolving rate of medicine and additive, and improves absorption utilization ratio, stability different kinds of available component and storage stability of feed supplement, covers bad flavor of medicine and additive, and increases palatability.

Description

【Technical field】 [0001] The invention relates to a feed additive, in particular to an aquatic feed additive wrapped with a polymer material, a drug and a drug-adding premix suitable for aquatic animals. 【Background technique】 [0002] Aquaculture is the fastest-growing part of agriculture and animal husbandry. The early aquaculture was small in size, low in intensification, and low in artificial breeding conditions. With the rapid development of China's aquaculture in recent years At the same time, the production and application of artificial feed, feed additives and fish medicines have also been developed rapidly. [0003] At present, in aquaculture, the use of feed additives and drugs is in open water bodies. Most of the additives and drugs have excellent water solubility, such as carnitine and betaine, which are important for fish growth. If it is directly fed in water without treatment, it can dissolve in water within a few seconds. In such a short period of time, the ...
