Disclosure of Invention
The invention aims to provide the Chinese herbal medicine feed additive for preventing and treating the digestive tract diseases of the pork pigs and the preparation method thereof, the raw materials are scientific and reasonable, the operability of the preparation process is strong, the prepared additive has good palatability, the occurrence of the digestive tract diseases of the pork pigs can be effectively prevented, the production performance, the anti-stress performance and the immunity of the pork pigs are improved, and the quality and the nutritional value of the pork are improved.
A Chinese herbal medicine feed additive for preventing meat pig digestive tract diseases comprises the following raw material components in parts by weight: 4-10 parts of poplar flower, 4-10 parts of purslane, 4-10 parts of Chinese pulsatilla root, 4-10 parts of radish seed, 4-10 parts of coarse coix seed, 4-10 parts of poria cocos, 2-8 parts of mangnolia officinalis, 2-8 parts of bighead atractylodes rhizome, 2-8 parts of elecampane, 2-8 parts of sophora flower, 2-8 parts of myrobalan, 2-8 parts of gordon euryale seed, 2-6 parts of astragalus membranaceus, 2-6 parts of codonopsis pilosula, 2-6 parts of scutellaria baicalensis, 2-6 parts of rhizoma atractylodis, 1-5 parts of roasted malt, 1-5 parts of kelp, 1-3 parts of hawthorn, 1-3 parts of dried orange peel and 1-3 parts of liquorice.
The preparation method of the Chinese herbal medicine feed additive comprises the following steps: sequentially extracting semen Raphani, Coicis semen, radix aucklandiae, fructus Chebulae and pericarpium Citri Tangerinae with 60-90% ethanol and drinking water under reflux, mixing extractive solutions, mixing water extracts of flos populi Davidianae, herba Portulacae, radix Pulsatillae, Poria, cortex Magnolia officinalis, Atractylodis rhizoma, flos Sophorae Immaturus, semen euryales, radix astragali, radix Codonopsis, Scutellariae radix, rhizoma Atractylodis, fructus crataegi and Glycyrrhrizae radix, concentrating the mixed solution, drying to obtain dry powder, mixing with pulverized parched fructus Hordei Germinatus powder and thallus laminariae powder, and packaging.
The method comprises the following specific steps:
(1) and crushing: pulverizing parched fructus Hordei Germinatus and thallus laminariae, and sieving with 80-160 mesh sieve;
(2) and leaching: reflux-extracting Raphani semen, Coicis semen, radix aucklandiae, fructus Chebulae and pericarpium Citri Tangerinae with 60% -90% ethanol with weight concentration of 4-8 times of the weight volume of the medicine for 0.5-1.5 hr, collecting ethanol extractive solution a, reflux-extracting with drinking water with weight volume of 4-8 times of the medicine for 2-3 times at 85-95 deg.C for 0.5-1.5 hr each time, and collecting extractive solution b; decocting poplar flower, purslane, Chinese pulsatilla root, poria cocos, mangnolia officinalis, bighead atractylodes rhizome, sophora flower, gordon euryale seed, astragalus, codonopsis pilosula, scutellaria baicalensis, rhizoma atractylodis, hawthorn and liquorice in 4-8 times of drinking water by weight volume of the medicines for 2-3 times, wherein each time lasts for 0.5-1.5 hours, and the temperature is 85-95 ℃, and collecting an extracting solution c;
(3) and (3) concentrating, namely mixing the extracting solutions a, b and c obtained in the step ⑵, and concentrating to obtain a concentrated solution with the relative density of 1.05-1.10 at the temperature of 40-60 ℃;
(4) and (3) spray drying: adding dextrin accounting for 1-3% of the weight of the concentrated solution, uniformly stirring, and carrying out spray drying;
(5) and (3) preparation: adding 0.02-0.05% of CMC and 0.03-0.05% of phospholipid by weight ratio into the dried powder after spray drying, and uniformly mixing;
(6) and sieving: sieving with 80-160 mesh sieve;
(7) and mixing: and (3) uniformly mixing the dry powder sieved in the step (6) with the fried malt powder and the laminaria powder obtained in the step (1), and packaging.
The application of the Chinese herbal medicine feed additive of the invention is as follows: the additive is added into daily feed (powder) of the pork pig according to the proportion that the weight ratio of the feed amount of the pork pig is 0.1-0.5%, the feed is carried out after the feed is evenly mixed, the feed can also be added into basic ration formula of the pork pig in the form of premix and granulated into granulated feed for feeding, and the Chinese herbal medicine feed additive is continuously added from 40kg of the pork pig in the whole process.
