Jerusalem artichoke extract for promoting feather development and application thereof

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 ...

AI Technical Summary

Problems solved by technology

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, the parasite sucks the blood of the chicken, leading to nutrient depletion, and there is also a mechanical stimulus, which causes the chicken to itch and feel uncomfortable, feather pecking occurs

[0004] In the breeding process of poultry, it is generally necessary to add a small amount of drugs to promote feather development and prevent feather pecking, such as feather-stimulating hormone and anetera, but the drugs are not suitable for long-term use in poultry
