Broiler, Mother and Child Crab Shell, Feed, Chitin Chitosan

Description

Feed containing broth and crab shells for broilers {Feed containing gulfweed and rind of crab for chicken and the chicken produced using IEC}

The present invention relates to a broiler feed prepared by adding a mother and crab shell to a general feed for broilers and broilers produced using the same. More specifically, the present invention relates to a broiler broiler containing a large amount of chitin chitosan produced by providing a feed for broilers prepared by adding a mother and crab shell to a general feed for broilers.

Chitin was first discovered in mushrooms in 1811 by Branconit, and was called shingles, and was renamed Chitin in 1823 by Ordier in order to form a microbial envelope. Was named by.

Chitin chitosan is a mixture of chitin and chitosan and is a high molecular weight bioactive substance. Chitin is a polysaccharide having a molecular weight of 1 million or more with N-acetyl-β-D-glucosamine residues of 5000 or more 1 to 4 carbon bonds, and chitosan is a substance having a structure in which acetyl groups are removed from chitin. It is present in shells of shellfish such as crabs and shrimps, shells of insects such as helmets and grasshoppers, shells of clams, oysters, and cell walls of mushrooms. In addition, according to recent research data, chitin chitosan absorbs and excretes excess harmful cholesterol in the body, that is, acts as a decholesterol, inhibits the proliferation of cancer cells, as well as chloride, which causes blood pressure to rise. By suppressing the adsorption and absorption in the intestine, the ions are discharged out of the body to inhibit blood pressure increase and to proliferate effective bacteria in the intestine and activate cells. In addition, blood sugar control, liver function improvement, and the effects of heavy metals and pollutants in the body are effective.

The inventors have identified the crab shell for use as a feed additive and have obtained it as a patent No. 1996-0016856. However, no studies have been conducted to find out the effects as a broiler feed additive by adding hatban as a plant material among seaweeds, which have completely different physicochemical properties from crab shells. Tests for use as feed additives confirmed a synergistic effect.

Mabanban is a brown algae plant and is a sea horse with Mabanban Hatban. It grows mainly in the lower intertidal zone. It is also commonly used to refer to a large brown algae belonging to the Mabanban family. It is dark yellowish brown and can be found all over the coast of Korea. However, these mother boards are sometimes a problem because they are pushed to the shore in large quantities. In addition, the crab, such as Yeongdeok Hong crab, reaches thousands of tons per year, even if the shell is discarded except for the decorative part.

Therefore, the present invention is often seen on the shore, or after a certain treatment, such as drying and powdering the discarded bark except the decorative part of the hat half and crab that is pushed in a large amount and then added to a regular feed The broilers produced by mixing and feeding have a high content of chitin chitosan, a chewy taste of meat, and a soft and light taste without the smell of chicken when compared to broilers fed general feed. Reached.

Accordingly, it is an object of the present invention to provide a method for producing a broiler feed by adding the mother and crab shell to the general feed for broilers. Another object of the present invention to provide a broiler feed prepared by the above method. Still another object of the present invention is to provide a broiler production method of feeding the prepared broiler feed for broilers three times a day. Still another object of the present invention is to provide a broiler produced by the broiler production method, containing a large amount of chitin chitosan, having excellent functional beauty and meat quality, and increasing unsaturated fatty acids.

The above object of the present invention is dried and crushed maban and crab shells, and then added to the general feed for broilers to prepare a broiler feed and the weight gain and feed intake of the prepared broiler, content of chitin chitosan, sensory beauty, meat quality, This was achieved by measuring the content of unsaturated fatty acids and confirming their superiority.

The method for producing a broiler feed for the present invention comprises the steps of: (a) drying the hat to make the water content 12-25% and then grinding; (b) drying the shell and then grinding the shell; (C) adding to the broiler general feed 2 to 4% by weight of the mashed crushed in the step (a) and 3 to 8% by weight of the crab shells pulverized in the step (b).

The broiler production method using the broiler feed of the present invention is preferably produced by feeding the broiler feed produced by the above method to the broiler three times a day.

Hereinafter, specific examples of the present invention will be described in detail with reference to examples and experimental examples, but the scope of the present invention is not limited thereto.
