Problems solved by technology

However, after our long-term observation, due to the existence of a large amount of gastric acid (hydrochloric acid) in the stomach of animals, basic salts (whether it is basic zinc chloride, basic copper chloride, basic zinc sulfate or other basic salts) in Under the action of gastric acid, part of it is dissolved and then absorbed by the intestinal tract as nutrients, thus losing antibacterial activity; and due to the dissolution in the stomach, the local proportion of one or several trace elements in the digestive tract is unbalanced, and trace element absorption antagonism appears , the absorption and utilization rate is further affected, which in turn leads to a large amount of trace elements being excreted from the body, causing a great burden on the environment

Embodiment 1

[0023] Example 1: Coated basic copper chloride and its application as a copper source additive in feed for weaned piglets.

[0024] A coated basic copper chloride, which is composed of a coated core material and a wall material for coating. The core material is granular basic copper chloride with a particle size of 50 μm to 1000 μm. The wall material is hydroxypropyl methylcellulose, which is resistant to gastric acid and can dissolve in the intestine of animals.

[0025] The basic copper chloride of the present embodiment adopts following process to prepare:

[0026] (1) Dissolving the commonly used adhesives in this field with water to prepare an adhesive solution with a mass concentration of 2% to 10%;

[0027] (2) Mix the core material basic copper chloride evenly and add it to the granulator, spray the prepared binder solution into the granulator;

[0028] (3) Add the wall material hydroxypropyl methylcellulose into deionized water to swell and disperse the wall materi...

Embodiment 2

[0051] Example 2: Coated basic zinc chloride and its application as a zinc source additive in feed for weaned piglets.

[0052] A coated basic zinc chloride, which is composed of a coated core material and a wall material for coating. The core material is granular basic zinc chloride with a particle size of 1 μm to 200 μm. The wall material is allicin, an organosulfur compound that is resistant to gastric acid and can dissolve in the intestines of animals.

[0053] The preparation process steps and process parameters of the coated basic zinc chloride in this example are the same as those in Example 1, except that the raw materials are replaced accordingly.

[0054] The basic zinc chloride of this embodiment is used as a zinc source additive in the feed of weaned piglets. The specific steps of application and implementation are as follows: select 90 weaned piglets, the piglets are of similar origin, age, weight, and male sex. 120 weaned piglets were randomly divided into 4 g...

Embodiment 3

[0064] Example 3: Coated basic zinc chloride and its application as a zinc source additive in broiler chicken feed.

[0065] A coated basic zinc chloride, which is composed of a coated core material and a wall material for coating. The core material is granular basic zinc chloride with a particle size of 1 μm to 200 μm. The wall material is an organic polymer material trimellitate that is resistant to gastric acid and can dissolve in the intestines of animals.

[0066] The basic zinc chloride of this embodiment is used as a zinc source additive in broiler feed, and the specific steps of application are as follows: select 1280 hatched Aviin broilers from the same batch, divide them into 4 groups, and repeat each group four times. (columns), 80 per pen, and the feeding cycle was 14 days. The basal rations of the two groups were the same (the basal rations already contained 40ppm of zinc sulfate as zinc element).

[0067] Control group: basal diet;

[0068] Implement a group...

Abstract

The invention discloses a coating type basic salt and application thereof. The coating type basic salt consists of a coated core material and a wall material used for wrapping. The core material is a granular basic salt, and the wall material is an organic high polymer material which resists gastric acid and can be dissolved in animal intestinal tracts or an organic sulfur compound. The coating type basic salt can be applied to the preparation of animal feed additives for preventing diarrhea and promoting growth. The coating type basic salt has the advantages of high biological value, low addition quantity, remarkable growth promotion effect, less side effects on animals, long-term use capability, safety, no drug resistance and the like.

Description

technical field [0001] The invention relates to the field of trace element additives for animal feed, in particular to a special dosage form of basic salt and its application in animal feed additives. Background technique [0002] At present, piglets in many pig farms are weaned at the age of 21 days, but growth retardation and high diarrhea rate of piglets after early weaning have always been a problem that plagues the pig industry. According to related data, adding high zinc (zinc oxide) to the basic diet of weaned piglets can reduce diarrhea and mortality of piglets, but the existing zinc source additives (such as zinc oxide) have low biological potency. The feeding effect must be increased, which will inevitably break the balance between various trace elements in the diet, resulting in an imbalance between nutrients and symptoms of poisoning in animals. More importantly, although a large amount of zinc source additives has played a role in preventing diarrhea to a certa...
