Description

Animal feed additives containing goji berry by-products

The present invention relates to a feed additive comprising wolfberry by-products, such as wolfberry stem, leaves, and sprouts. More specifically, the present invention relates to a method for producing high-quality meat with reduced cholesterol content by feeding a feed comprising animal feed and an electric feed additive containing crude fiber, crude ash and essential amino acid-rich goji by-products to livestock. .

Lycium chinense Miller is a deciduous broad-leaved shrub belonging to the family Solanaceae, which has strong vitality and has branched leaves. The thorns are like the thorns of a tangerine tree, and the stems are called goji (고리) because they are similar to wicker (,). Fruits goji (Lycii fructus), leaves goji leaf (Lycii folium), the root of the phalanx Lycii cortex radicis). In Korea, in the spring, we remove ground parts like mulberry trees and grow 3 ~ 5 new shoots to harvest wolfberry, but in the Greater China, a large-scale plantation, we grow one stem like a jujube tree, and 3 ~ 5 branches are grown there. We harvest with paste, and cultivation method is very different.

As described above, since the goji fruit is fruited in a new branch by nature, the goji stems had to be cut every year like a mulberry tree, and its utilization value was not so much emphasized, and the farm farmers struggled every year. Gojija cultivated farmers cut the remaining goji berry stems after harvesting fruit every year and gathered them in the middle of the field where they were thawed, and burned them. Population has been heavily polluted in the production area, and in the case of Goji-sun, which is mass-produced nationwide, it is thrown into the field every year.

On the other hand, the pharmacological action and efficacy of goji berries are known in ancient and internal books, such as Dongbobogam, hyangjeokbangbang, new agricultural herbaceous, herbaceous landlords, medicinal herb, herbaceous wood, herbivory, Chinese medicine, introduction to pharmacy. It has been known that phalanges have a lowering effect on blood sugar and cholesterol, inhibit the sedimentation of fats into hepatocytes, increase serum and phospholipids, and lower the blood sugar and cholesterol levels similar to the phalanges of roots. It turns out that Goji sprout produced in early spring is not only a pollution-free food, but also contains a large amount of various vitamins, high-quality fatty acids and essential amino acids. In addition, Goji-soon contains a large amount of rutin (rutin), which serves to reduce blood cholesterol content and blood sugar. Goji leaves are effective in treating tonic, antipyretic, pulmonary tuberculosis, and diabetes mellitus. Fruit and goji leaves are also used as tea ingredients.

Therefore, the inventors of the present invention, as a result of earnest research to overcome the problems in the treatment of goji by-products such as stems, leaves, sprouts, etc., and to make efficient use of resources, as a result, to prepare a feed additive containing goji by-products, including As a result of feeding the feed to livestock, it was found that high-quality meat with reduced cholesterol content could be produced, thus completing the present invention.

After all, the main object of the present invention is to provide a feed additive comprising wolfberry by-products.

Another object of the present invention is to provide a method for producing high-quality meat with reduced cholesterol content by feeding a feed comprising an electric feed additive to the livestock.

Hereinafter, a feed additive including a wolfberry by-product according to the present invention will be described in more detail.

The feed additive of the present invention includes goji berry by-products such as goji berry stem, goji leaves and goji-sun as an active ingredient. In the case of chlorine, by-products such as goji stalks, goji leaves and goji-soon are supplied as it is, manufactured by the raw goji by-product itself, and finely ground to 5 ~ 6㎜ for Hanwoo, 3 ~ 4㎜ for broilers Since it is preferable to feed by, the gojija by-products are prepared by grinding, in the case of gojija stems it is preferable to grind using a specially manufactured high-fiber centrifugal mill. In addition, when the feed additive of the present invention is stored and used for a long time, the water content is manufactured by drying to 15% by weight or less, and used in a container that can block moisture such as a vinyl bag.

On the other hand, the feed additive is mixed with the usual livestock feed to feed the livestock, it is preferable to add an amount of about 5 to 20% by weight based on the whole feed. In the case of mixing, it is easy to mix in the case of powder feed, but in the case of pellet or crumble feed, it is not easy to mix with the feed evenly because the particle size is different. To manufacture).

The present inventors raise livestock for a certain period of time using livestock fed a feed containing a feed additive including a wolfberry by-product as a control, a livestock fed only a normal livestock feed, and measuring the weight gain after breeding, blood test, sensuality Inspection, fatty acid assay, etc. were performed.

Hereinafter, the present invention will be described in more detail with reference to Examples.

These examples are only for illustrating the present invention, and it will be apparent to those skilled in the art that the scope of the present invention is not limited to these examples according to the gist of the present invention. In particular, the following examples show the case of breeding broiler and Hanwoo with feed additives based on goji berry stem, but the same results as in the following example even if other livestock are raised using Goji leaf and Goji sprout As can be expected, it is clear that the scope of the present invention is not limited to the wolfberry by-products and livestock illustrated in the following examples.

Example 1 Preparation of Feed Additives

The wolfberry stem was cut at a position close to the ground with a power mower, and the cutting teeth of the cutter were adjusted to be cut as small as possible and cut to about 3 cm. The cut wolfberry stem was ground to a size of about 3 to 6 mm using a high-fiber centrifugal mill specially manufactured to make 2,500 revolutions per minute. The pulverized wolfberry stem was hot-air dried to 15% by weight or less of water to prepare a feed additive including the wolfberry stem. The ingredients of the feed additives were compared with those of commercial feeds (Hitec 350, dominant feeds) and the feed additives mixed with 20% by weight of feed additives in commercial feeds, and the results are shown in Tables 1 to 4 below. Indicated.
