Problems solved by technology

In order to prevent animal diseases, promote animal growth and improve feed utilization, a large number of antibiotics, chemically synthesized drugs or hormone drugs are used as feed additives. After long-term and large-scale trials of such additives, their negative effects are increasingly apparent. The main manifestations In: leading to the increasingly serious problem of bacterial resistance; leading to the decline of animal immunity; the imbalance of internal and external flora in the body, causing endogenous and exogenous infection in animals; causing residues in animal products and the environment, which will affect human health. serious threat

Embodiment 1

[0017] The raw material prescription is: astragalus 100g, fried divine song 80g, fried malt 80g, atractylodes 60g, echinacea 80g; appropriate amount of sucrose and dextrin.

[0018] Preparation of granules: take the Echinacea purpurea medicinal material, crush it into a coarse powder, add 60% ethanol 10 times the weight of the medicinal material, soak for 60 minutes, reflux extraction once, the extraction time is 2 hours, filter, and add 60% of the medicinal residue to 8 times the weight of the medicinal material. % ethanol, reflux extraction once, the extraction time is 1h, filter, combine the two filtrates, recover ethanol under reduced pressure, concentrate to a thick paste, and set aside. Take astragalus, fried Shenqu, fried malt, atractylodes and other 4 medicinal materials and mix according to the prescription ratio, add the Echinacea purpurea dregs extracted twice, add 10 times the amount of cold water to soak for 60 minutes, decoct for 120 minutes, filter, add 8 times t...

Embodiment 2

[0020] The raw material prescription is: astragalus 100g, fried divine music 75g, fried malt 75g, herb 50g, echinacea 100g; appropriate amount of sucrose and dextrin.

[0021] Preparation of granules: Take Echinacea purpurea medicinal material, crush it into coarse powder, add 10 times the weight of the medicinal material in 70% ethanol, soak for 60 minutes, reflux extraction once, the extraction time is 2 hours, filter, and add 40% of the medicinal residue, which is 10 times the weight of the medicinal material. % ethanol, reflux extraction once, the extraction time is 1h, filter, combine the two filtrates, recover ethanol under reduced pressure, concentrate to a thick paste, and set aside. Take astragalus, fried Shenqu, fried malt, atractylodes and other 4 kinds of medicinal materials, mix according to the prescription ratio, add 10 times the amount of cold water to soak for 60 minutes, decoct for 120 minutes, filter, add 10 times the amount of medicinal materials to decoct i...

Embodiment 3

[0023] The plant feed additive that embodiment 1 makes (hereinafter described as " product of the present invention ") is to the impact test of sheep immune-promoting effect:

[0024] Select 40 6-12-month-old Yunling black goats from the breeding sheep farm in Yunnan Province as test subjects, and divide them into product group of the present invention, Sijunzi powder group, Qiangqiang powder group and blank control group, 10 in each group. The test is divided into a preliminary test period and a full test period. The pre-feeding period was 7 days, 1 / 4 of the test amount was added on the 1st-2d, 1 / 3 of the test amount was added on the 3rd-4d, 2 / 3 of the test amount was added on the 5th-6d, and the test amount was added on the 7th day. During the pre-test period, the test sheep were routinely dewormed, weighed and earmarked; the main test period was 60 days, during which the free and sufficient drinking water of the test flock was guaranteed, and the diseased and eliminated tes...

Abstract

The invention discloses an immunity-improving vegetable feed additive for sheep. The vegetable feed additive is prepared from 6-15 parts of Astragalus mongholicus, 6-15 parts of stir-fried medicated leaven, 6-15 parts of stir-fried malt, 4-10 parts of Rhizoma atractylodis and 4-15 parts of Echinacea and has the functions of improving immunity of sheep and further improving disease resistance of sheep. The vegetable feed additive is safe and efficient.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to the development and application of a botanical immunity-promoting feed additive for sheep. Background technique [0002] With the development of modern intensive farming, the risk of animals being infected with various diseases is increasing. In order to prevent animal diseases, promote animal growth and improve feed utilization, a large number of antibiotics, chemically synthesized drugs or hormone drugs are used as feed additives. After long-term and large-scale trials of such additives, their negative effects are increasingly apparent. The main manifestations In: leading to the increasingly serious problem of bacterial resistance; leading to the decline of animal immunity; the imbalance of internal and external flora in the body, causing endogenous and exogenous infection in animals; causing residues in animal products and the environment, which will affect human heal...
