[0024] (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...

[0033] Effects of Compound Plant Extract Feed Additives on Growth Performance of Goslings

[0034] 120 12-day-old goslings with similar body condition were selected for the experiment, and they were randomly divided into 2 groups, with 3 repetitions in each group, 20 goslings in each repetition, and the test period was 30 days.

[0035] The control group was fed with basal diet, and the test group was fed with compound plant extract feed additive plus basal diet. Add the compound plant extract feed additive of the present invention in the basal diet at a ratio of 1 g / head. All the goslings were free to eat and drink, and the feed intake of the test goslings was recorded in detail every day, and the diarrhea of ​​the goslings was observed, and the rest of the management was carried out as usual. All goslings were weighed before and at the end of the experiment, and the average daily gain, daily feed intake and feed-to-meat ratio were calculated.

[0040] Effects of Compound Plant Extract Feed Additives on Growth Performance of Broilers

[0041] In the experiment, 600 broiler chickens with similar body condition at 21 days old were randomly divided into 2 groups, with 3 repetitions in each group, 100 chickens in each repetition, and the test period was 30 days.

[0042] The control group was fed with basal diet, and the test group was fed with compound plant extract feed additive plus basal diet. Add the compound plant extract feed additive of the present invention in the basal diet at a ratio of 1 g / head. All broilers had free access to food and water, and the feed intake of the experimental broilers was recorded in detail every day, and the mental state of the broilers was observed, and the rest of the management was carried out as usual. All broilers were weighed before and at the end of the experiment, and the average daily gain, daily feed intake and feed-to-meat ratio were calculated.

Abstract

The invention relates to the technical field of feed additives, in particular to a functional feed additive capable of significantly improving a poultry immunity function and a digestion and absorption function and with the efficacy of fattening poultry and promoting growth, and a preparation method thereof. The method comprises the following steps: screening target plants: screening out four target plants of tuber fleeceflower stems, Chinese magnoliavine fruits, debark peony roots and smallanthus sonchifolius from 236 traditional Chinese medicines available for the poultry according to required active ingredients; preparing plant polysaccharides, oligosaccharides and reducing sugar; and selecting plant extracts with different proportions, and mixing the plant extract with a proper amountof carriers according to the physiological characteristics and requirements of different poultry so as to obtain the feed additive.

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 capable of significantly improving poultry immunity. 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. As one of the source links, the poultry breeding industry is directly related to the major issues of human physical and mental health, social stability and development, and must be paid attention to. However, in the current aquaculture industry, poultry have low immunity, poor digestion and absorption capacity, and reduced vitality. Even with the best feed and breeding methods, poultry with first-class breeding indicators cannot be fed. [0003] In order to solve the sub-health of poultry and ensure the safety of pou...
