preparation example Construction

[0028] (2) Preparation of plant polysaccharides: After crushing the dried vine and schisandra with a 0.6mm sieve, add 6-8 times the weight of water to the container and mix evenly, soak for 1 hour, then heat and boil, and control the temperature at 70°C -90°C, keep it for 2-3h, lower the temperature to 40-50°C, adjust the pH value to 5-7, add mixed enzymes, enzymatic hydrolysis for 3-4h, centrifugal filtration, when the filtrate is concentrated to 1 / 4 of the total amount, add 95 % ethanol, put it aside for 1-2 hours, centrifuge, get the precipitate and dry and pulverize to obtain the crude extract; fully dissolve the crude extract into a 1-5wt% aqueous solution with distilled water, and perform ultrafiltration with an ultrafiltration membrane with a molecular weight cut-off of 5000Da. Filtration, the retentate with a molecular weight greater than 5000 and the permeate with a molecular weight less than 5000 can be obtained, and then the polysaccharide solution with a molecular w...

[0043] Use example 2: Effect of compound plant extract feed additive on growth performance of fattening pigs

[0044] For the experiment, 48 fattening pigs with similar body condition were selected and randomly divided into 2 groups, with 3 repetitions in each group, 8 pigs in each repetition, and the test period was 60 days.

[0045] The control group was fed the basal ration, and the test group was the compound plant extract feed additive group, and the compound plant extract feed additive of the present invention was added to the basal ration at a ratio of 0.25%. All pigs had free access to food and water, and the feed intake of the experimental pigs was recorded in detail every day, and the rest of the management was carried out as usual.

[0046] All test pigs were weighed before and at the end of the test to calculate the average daily gain, daily feed intake and feed-to-meat ratio; Effects of plant extract feed additives on functional organs and meat quality of finishi...

Abstract

The invention relates to the technical field of feed additives, in particular to a functional feed additive capable of significantly improving immune functions and digestive absorption functions of animals and having fattening and growth promoting effects as well as a preparation method of the feed additive. The preparation method comprises the steps as follows: screening target plants: screeningout four target plants, including tuber fleeceflower stems, fructus schisandrae, white peony roots and yacon, from 236 traditional Chinese medicines available to animals according to required active ingredients; preparing plant polysaccharides; preparing plant oligosaccharides and reducing sugar; and selecting plant extracts in different proportions according to physiological characteristics and requirements of different animals to be mixed with a proper quantity of carrier to prepare the product.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a preparation method of a plant extract-based feed additive that can significantly improve animal immune function, digestion and absorption function, and has the effect of increasing fat and promoting growth. Background technique [0002] In recent years, food safety problems have emerged one after another, and food safety has attracted more and more attention from the society and the public. To solve food safety problems, we must start from the source. Animal husbandry, as one of the source links, is directly related to human physical and mental health, social stability and development, and must be paid attention to. At present, the sub-health of animals has become a common state. Although animals have no clear disease characteristics, their overall immunity is low, their digestion and absorption capacity is poor, and their vitality is reduced. Even with the best feed and...
