Embodiment 1

[0026] The coated mineral feed additive is composed of an inner layer, a binder, an outer layer and a coating layer; wherein, the inner layer is K 2 Mg[SO 4 ] 2 ·nH 2 0; the binder is common maltose syrup; the outer layer is potassium bicarbonate; the coating layer is an enteric-coating inclusion material hypromellose phthalate, ie HPMCP.

[0027] The feed additive comprises the following raw materials in parts by weight:

[0028]

[0029] The preparation method of the coated mineral feed additive comprises the following steps:

[0030] ⑴Weigh 30 parts of potassium magnesium vanadium, 10 parts of starch and 20 parts of water to fully mix to make a paste mixture, put it into a swinging granulator to make wet granules, and pass through a 16-mesh sieve;

[0031] (2) Put the wet granules described in step (1) into 28 parts of ordinary maltose syrup and soak for 3 minutes;

[0032] (3) Take by weighing 15 parts of potassium bicarbonate, 10 parts of starch and 20 parts of wa...

Embodiment 2

[0038] In this case, the farrowing sows were grouped for a comparative feeding experiment. There were 480 sows in the experiment, with an average parity of 2.3, and they were randomly divided into the experimental group and the control group. The experimental group added 5kg / ton of full-price feed as in Example 1. The products mentioned in the above, the control group was common full-price feed, and other feeding conditions were the same. For a period of six months, the average daily feed intake of sows, the incidence of constipation during pregnancy, the average litter size, the average live piglet size, and the average weaning weight of piglets were recorded. The results are shown below.

Embodiment 3

[0041] The present embodiment adopts fattening pig grouping to carry out comparative feeding experiment, experiment fattening pig altogether 100, initial average body weight is 81kg, is divided into experimental group and control group at random, and experimental group adds 5kg / ton in the feed as in embodiment 1 Described product, control group is common feed, and other feeding conditions are identical. For a period of 21 days, the average daily weight gain, average daily feed intake and feed-to-meat ratio of the finishing pigs were recorded, and the results are shown below.

[0042] group control group test group Average daily gain, g 949.68±22.66 993.94±44.14 Average daily feed intake, g 3036.07±87.72 3097.96±115.96 average feed to meat ratio 3.20±0.12 3.14±0.21

Abstract

The invention relates to a coated mineral feed additive and a preparation method thereof. The feed additive includes the following raw materials: lconite, potassium bicarbonate, HPMCP, maltose syrup and starch. The preparation method includes the following steps: (1) weighing the lconite and the starch, mixing the weighed lconite and starch with water to make a paste-like mixture, and putting thepaste-like mixture into an oscillating granulator to make wet granules; (2) soaking the wet granules described in step (1) in the maltose syrup for 2-3 minutes; (3) weighing the potassium bicarbonateand the starch in set dosages, mixing the weighed potassium bicarbonate and starch with water to make a paste-like mixture; (4) putting the wet granules soaked in the maltose syrup obtained in step (2) into the paste-like mixture described in step (3), and putting the mixture into the oscillating granulator to make wet granules; (5) weighing the HPMCP, dissolving the weighed HPMCP with water to obtain coating solution; (6) atomizing the coating solution to be sprayed on the surface of loose granules, carrying out wetting, spreading, coalescence, adhesion and drying until continuous coating-films are formed on the surfaces of the granules, with the weight of the coating-films accounting for 5-10% of the total weight of the tablets; and (7) carrying out mesh-screening and separate-packing, thereby obtaining the finished products.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a coated mineral feed additive and a preparation method thereof. Background technique [0002] Potassium is the main cation in the intracellular fluid. It can maintain the balance of membrane potential and intracellular fluid, participate in biochemical reactions, and is also necessary for the normal activity of the heart. It can weaken myocardial contraction and facilitate cardiac relaxation. When it is lacking, the muscles of the whole body are weak, showing that the legs cannot stand, the intestines are tense and incomplete and swollen, heart failure and respiratory weakness, and death may occur after convulsions in severe cases. Potassium bicarbonate and potassium sulfate in langbeinite are excellent choices of potassium supplements with good water solubility and high biological availability. They can also be used as feed electrolyte regulators to adjust dietary electrolyte bala...
