preparation example Construction

[0034] The present invention also provides a catechin animal feed, which is prepared by the following method:

[0035] S1. Prepare the coating material and dissolve the coating material to form a coating solution;

[0036] S2. Place the feed additive in the coating solution for coating, take out and volatilize to remove the solvent, and obtain the coating feed additive;

[0037] S3. Based on the mass of the feed additive, according to the mass ratio, the coated feed additive is mixed with the basic feed to obtain the animal feed.

[0038] Further preferably, the specific methods of steps S1 and S2 are:

[0039] S1. Prepare 2 parts by mass of zein and 1 part of plasticizer to dissolve in 0.5 part of organic solvent to form coating solution A, and dissolve 1 part by mass of pectin and 1 part of plasticizer in 98 Form coating solution B in part water;

[0040] S2. Feed additive is placed in coating solution B and carries out coating film, takes out and is placed in coating sol...

Embodiment 1

[0045] This example provides an animal feed additive containing catechin, the preparation method of which is as follows: 250 mg of epigallocatechin gallate, 250 mg of epigallocatechin and 250 mg of epicatechin are uniformly mixed to obtain a catechin mixture , 60mg ferrous gluconate, 100mg iodine content Iodized salt, 4mg selenium-enriched yeast, 80mg zinc glycyrrhizinate, 80mg vitamin D, 25mg vitamin B12 and 30mg citric acid were mixed uniformly to obtain auxiliary agent, and catechin was mixed uniformly with auxiliary agent to obtain feed additive. 2 parts of zein by mass and 1 part of plasticizer are dissolved in 0.5 part of organic solvent to form coating solution A, and 1 part by mass of pectin and 1 part of plasticizer are dissolved in 98 parts of water Form the coating solution B; put the feed additive in the coating solution B to coat the film 1 to 2 times, each coating time is 2 to 5 seconds, take it out after coating and dry it, and then place it in the coating solu...

Embodiment 2

[0047] This embodiment provides an animal feed additive containing catechin, the preparation method of which is as follows: mix 125 mg of epigallocatechin gallate, 125 mg of epigallocatechin, 125 mg of epicatechin and 125 mg of epicatechin Gallic acid is evenly obtained catechin mixture, 30mg ferrous gluconate, 100mg iodine content Iodized salt, 3mg selenium-enriched yeast, 50mg zinc glycyrrhizinate, 50mg vitamin D, 10mg vitamin B12 and 20mg succinic acid were mixed uniformly to obtain the auxiliary agent, and catechin was mixed uniformly with the auxiliary agent to obtain the feed additive. 2 parts of zein by mass and 1 part of plasticizer are dissolved in 0.5 part of organic solvent to form coating solution A, and 1 part by mass of pectin and 1 part of plasticizer are dissolved in 98 parts of water Form the coating solution B; put the feed additive in the coating solution B to coat the film 1-2 times, each coating time is 2-5 seconds, take it out after coating and dry it, a...

Abstract

The invention provides application of catechin to preparation of an animal feed additive and feed, the catechin is one or more of epigallocatechin gallate, epigallocatechin, epicatechin and epicatechin gallic acid, and the catechin is applied to preparation of the feed additive for improving the physique of newborn animals. When the catechin animal feed additive is applied to prepare a catechin feed, the addition amount of catechin is 0.05-20% based on the total mass of the feed, nutrient element absorption of a parent body is increased, nutrient element absorption of a daughter in the parent body and formation of an immune system are promoted, nutrient element storage of the daughter is increased, the physique of a newborn animal is improved, the weight of the newborn animal is increased, and the survival rate of the newborn animal is increased. The survival rate of newborn animals is improved.

Description

technical field [0001] The invention relates to the technical field of animal feed additives, in particular to the application of catechins to prepare animal feed additives and feed thereof. Background technique [0002] Animal husbandry is an important part of the basic agricultural industry. Its level of development is directly related to the level of agricultural production. It is an important symbol of a country's national living standards. The proportion of animal husbandry production in developed countries to agricultural production is 50%. For example, the United States accounts for 50.1%, the United Kingdom accounts for 59.8%, and countries with relatively developed animal husbandry, such as New Zealand and Australia, account for more than 70% of agriculture. And my country's animal husbandry output value only accounts for about 35% of agricultural output value, so my country's vigorous development of animal husbandry just seems a long way to go. There are many prob...
