Problems solved by technology

However, the production process of this method is long, the single batch output is low, and the production efficiency is low.
In addition, the extrusion granulation method adopted by the second-level coating of this method will damage the first-level coating particles, resulting in the ineffectiveness of the first-level coating.

Embodiment 1

[0040] Embodiment 1, prescription screening

[0041] Investigate two main indicators: in vitro dissolution and moisture resistance.

[0042] 1. In vitro dissolution of microencapsulated calcium chloride

[0043] The pH of the rumen of dairy cows is between 6.2 and 6.8, the pH of the abomasum of dairy cows is about 1.2 when they are fasting, and about 4.3 when they are full. Choose pH 6.8 phosphate buffer to simulate rumen environment, and pH 1.2 and 4.3 to simulate dairy cow abomasum environment.

[0044] The reagents used are as follows:

[0045] In vitro simulated abomasal juice Ⅰ, i.e. hydrochloric acid solution with pH = 1.2, accurately measure 425mL of 0.2mol / L hydrochloric acid solution, dilute with water to 1000mL, shake well, and obtain;

[0046] In vitro simulated abomasal juice II, that is, acetic acid buffer solution with pH=4.3, accurately weigh 1.99g of sodium acetate and place it in a 1000mL volumetric flask, add water to dissolve it, add 17.7mL of 2mol / L acet...

Embodiment 2

[0075] Embodiment 2, prepare microcapsule calcium chloride

[0076] Put 186kg of hydrogenated oil into a jacketed heating tank to melt, control the jacket temperature to 100°C, transfer the melted hydrogenated oil to the dispersion stirring tank, maintain the jacket temperature of the dispersion stirring tank at 80°C, start the mixer, and gradually add 18kg glyceryl monostearate, 96kg calcium chloride raw material (calcium chloride content is 93.6wt%), after stirring, start shearing machine, homogenizer, make material mixing and homogeneous emulsification, obtain compound, then The mixture is sent to the centrifugal spray tower, the inlet air temperature of the centrifugal spray tower is controlled to be less than or equal to 5°C, the speed of the centrifugal turntable is 3000r / min, and the air volume is 30000m 2 / min to obtain microencapsulated calcium chloride granules, sieve them with a vibrating sieve, collect microencapsulated calcium chloride granules with a particle dia...

Embodiment 3

[0078] Embodiment 3, prepare microcapsule calcium chloride

[0079] Put 153kg of hydrogenated oil into the jacketed heating tank to melt, control the jacket temperature to 100°C, transfer the melted hydrogenated oil to the dispersion stirring tank, maintain the jacket temperature of the dispersion stirring tank at 80°C, start the mixer, and gradually Add 18kg glyceryl monostearate, 129kg calcium chloride raw material (calcium chloride content is 93.6wt%), start shearing machine, homogenizer after stirring evenly, make material mixing and homogeneous emulsification, obtain compound, then The mixture is sent to the centrifugal spray tower, and the air inlet temperature of the centrifugal spray tower is controlled to be less than or equal to 5°C, the speed of the centrifugal turntable is 3000r / min, and the air volume is 30000m 2 / min to obtain microencapsulated calcium chloride granules, sieve them with a vibrating sieve, collect microencapsulated calcium chloride granules with a...

Abstract

The invention discloses micro-capsule calcium chloride for dairy cows as well as a preparation method and application of the micro-capsule calcium chloride. The microcapsule calcium chloride feed additive is prepared from the following components in percentage by mass: 25-65% of a capsule material, 1-10% of an emulsifier and 30-70% of calcium chloride, wherein the capsule material is hydrogenatedoil or paraffin, and the emulsifier is at least one selected from the group consisting of glyceryl monostearate, glyceryl distearate and glycerol monolaurate. According to the invention, materials aresheared, homogenized and emulsified through a dispersing and stirring kettle so as to allow calcium chloride and a capsule material to be mutually embedded in a molecular form, and the micro-capsulecalcium chloride is prepared through a high-speed suspension condensation granulation process; the micro-capsule calcium chloride is not damaged when passing through a rumen, starts to disintegrate and dissolve out in the true stomach of a dairy cow and is efficiently absorbed in the intestinal tract of the dairy cow, so the effect of an anionic salt is given to play, and metabolic diseases causedby postpartum hypocalcemia of the dairy cow are reduced. A microcapsule calcium chloride feed additive provided by the invention remarkably improves the moisture absorption of calcium chloride, covers the irritation of calcium chloride, and improves the palatability of calcium chloride.

Description

technical field [0001] The invention relates to a microencapsulated calcium chloride for dairy cows and a preparation method and application thereof, belonging to the technical field of feed additives. Background technique [0002] Dairy cows undergo physiological changes such as pregnancy, childbirth, and lactation during the perinatal period. Both endocrine and nutritional metabolism undergo drastic changes. Dairy cows are prone to hypocalcemia, retained placenta, abomasum displacement, and postpartum paralysis. disease. Therefore, the perinatal period is also called the "pathological period". The balance of blood calcium in dairy cows is a complex process of intake, output, and recirculation. During the peripartum period, dairy cows require less calcium, and the supplementary mechanism of blood calcium is relatively inactive; During milk secretion, the demand for calcium rises suddenly, but the regulation mechanism of calcium in the body cannot be activated quickly to m...
