2. Improper feeding and management, such as when the house is too dry, the skin will feel uncomfortable, so it will peck itself, and then develop into feather pecking each other
3. Diseases: especially chronic intestinal diseases, leading to malabsorption of nutrients and feather pecking; internal parasites such as roundworms and tapeworms will also cause feather pecking due to malnutrition; external parasites such as mites, feather lice, etc. When present, t

Embodiment 1

[0031] Example 1: Preparation of Jerusalem artichoke tuber extract:

[0032] (1) Jerusalem artichoke tuber pretreatment

[0033] Wash the fresh Jerusalem artichoke tubers and cut them into shreds with a width of 0.2-0.3cm.

[0034] (2) Preparation of inulin crude extract

[0035] The shredded Jerusalem artichoke was placed in hot deionized water at 60°C according to the ratio of material to water of 1:12.5 (W / V), and soaked for 120 min to obtain a crude extract of Jerusalem artichoke; the crude extract was filtered out, and the above steps were repeated. , extract the Jerusalem artichoke silk again. Combine the liquids from the two extractions. The crude extract is passed through an ultrafiltration membrane with a nominal molecular weight of 4000 Daltons, and the obtained filtrate is concentrated under reduced pressure and spray-dried to obtain the Jerusalem artichoke tuber extract.

Embodiment 2

[0036] Example 2: Preparation of Jerusalem artichoke leaf extract:

[0037] 100g of fresh Jerusalem artichoke leaves were washed and dried, pulverized to 5 mesh, added to a stirring reaction kettle containing 375g of deionized water pre-added with 240g of methanol, vortexed and ultrasonicated for 45s, and then leached in a 65°C water bath for 2h. Vortex for 45s for 30min to obtain the extract. The extract is passed through an ultrafiltration membrane with a nominal molecular weight of 2000 Daltons, and the obtained filtrate is concentrated under reduced pressure and spray-dried to obtain the Jerusalem artichoke leaf extract.

Embodiment 3

[0039] The taro tuber extract prepared in Example 1 and the Jerusalem artichoke leaf extract prepared in Example 2 were mixed in a mass ratio of 2:1 to obtain the Jerusalem artichoke extract, which is a feed additive.

Abstract

The invention discloses a jerusalem artichoke extract for promoting feather development and application of the jerusalem artichoke extract. The jerusalem artichoke extract comprises a jerusalem artichoke tuber extract and a jerusalem artichoke leaf extract in a mass ratio of 1 (1-3): A preparation method of the jerusalem artichoke tuber extract comprises the following steps: shredding jerusalem artichoke tubers, heating and extracting with deionized water, and filtering to obtain a crude extracting solution; and filtering the crude extract by using an ultrafiltration membrane to obtain filtrate, concentrating the filtrate under reduced pressure, and drying to obtain the jerusalem artichoke tuber extract. The preparation method of the jerusalem artichoke leaf extract comprises the following steps: heating and extracting fresh jerusalem artichoke leaves with methanol/water, filtering with an ultrafiltration membrane to obtain a filtrate, concentrating under reduced pressure, and drying to obtain the jerusalem artichoke leaf extract. The jerusalem artichoke extract is prepared by extracting jerusalem artichoke tubers and jerusalem artichoke leaves, and the jerusalem artichoke extract is used as a feed additive and can promote feather development of poultry, improve feather bulkiness and prevent feather picking.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a Jerusalem artichoke extract for promoting feather development and application thereof. Background technique [0002] Feather is a keratinized product derived from avian epidermal cells. It covers the body surface. It is light and tough, slightly elastic, waterproof, and has functions such as body protection, heat preservation, and flying. It is also a unique skin derivative of poultry, covering almost the whole body of the bird; there is a gap in the middle to reduce the quality of the feathers; it is light and tough, elastic and warm. Feather pecking is often seen in the breeding process of birds. Feather pecking in poultry will lead to increased death of poultry groups and reduce production performance. For poultry, due to the untidy feathers, it will also affect sales and reduce economic benefits. [0003] Poultry with feathers is also prone to feather pecking during the ...
