Description

[0001] The present invention relates to a feedstuff additive containing by-product of fermented Schisandra chinensis using sugar,

The present invention relates to a livestock feed composition containing a by-product of an omelet sugar fermented product.

In breeding livestock such as chickens, pigs, cattle, etc., a variety of formulated diets containing suitable nutrients are commonly used to maintain the health of the livestock and to fully demonstrate the production capacity of the livestock. Conventionally, in order to improve the quality of livestock such as meat, hairs, milk, eggs and the like provided by livestock, or to improve the health of livestock, additives such as enzymes, yeast, probiotics and antibiotics, Were added to feed the animals. However, most of these materials are high-priced materials, and when they are added to livestock feed, the cost of the feed is increased, and the utilization of the feed additives as a feed additive is not high.

Domestic animals are all animals that are useful for mankind life, where mankind tamed or improved wild animals. It mainly provides livestock products and is used in ministry. In this case, useful things include the production of livestock products such as milk, meat, eggs, hair, leather, and feathers, and the use of force for ministry, as well as pets for enjoyment of appearance, action and sound. The following are treated as livestock in the world today. Mammals include carp, goldfish, insects such as horses, donkeys, cattle, buffalo, sheep, goats, camels, reindeer, pigs, dogs, cats, rabbits and birds such as chickens, turkeys, geese, ducks, Silkworms, and bees. However, except for fish and insects, mammals and birds are sometimes referred to as livestock. Birds belonging to algae are sometimes referred to as poultry (poultry) and sometimes excluded from livestock. In some cases, mammals are sometimes referred to as livestock .

Schizandra chinensis (Schizandra chinensis ) is a ball shaped, about 1 cm in diameter, and has a dark red color. It contains 1-2 drops of red juice and reddish brown seeds. There are five flavors of sweetness, sourness, bitter taste, salty taste and spicy taste, among which the sour taste is strong. There are two types of omija (north omija), south omija, and black omija. Omiza grows mainly in the area of Taebaek Mountain, Namimiza grows in the southern island region, and black omija grows in Jejudo. It is produced in Korea, Japan, Sakhalin, and China. Omija contains isozindrine, gomilin, citral, malic acid, citric acid, etc. It strengthens the heart, lowers the blood pressure and improves immunity and is used as tonic. It also strengthens the pulmonary function and helps to treat coughs and thirst by having a deep-seated and deep-seated action. Put the dried fruit of Omija in cold water and put it in red water, drink honey or sugar and put it in a bowl or starch. Chestnuts, jujube, and mushrooms are put together and boiled to make tea or soak. In recent years, the liquid phase of fermented omiza with a sugar such as sugar is used as a beverage. On the other hand, the by-products remaining after collecting the liquid phase of the omiza saccharide fermented product contain various nutritional ingredients of omija and various kinds of oil-soluble ingredients produced through fermentation. However, most of the by-products are discarded as food waste, There are no confirmed cases.

Accordingly, the inventors of the present invention have conducted studies on a livestock feed composition which is capable of breeding livestock healthily and promoting the growth of livestock. In the case of using the livestock feed composition containing by-products of the above- And that the quality of the meat obtained from the meat is improved, thereby completing the present invention.

Hereinafter, the present invention will be described in detail.

The by-product of the fermentation product of Omija fermented product is obtained by fermenting a mixture of 50-200 parts by weight of sugars on the basis of 100 parts by weight of Omija for 3-12 months, preferably 3 to 6 months, At this time, when the saccharide is mixed in an amount of less than 50 parts by weight based on 100 parts by weight of the omelet, the fermentation does not occur and it tends to be corrupted. In addition, when the saccharide is mixed more than 200 parts by weight on the basis of 100 parts by weight of the omija, the quality of the livestock meat fed with the feed composition to which the by-product of the omija fermentation product is added due to the addition of the saccharide ingredient may be deteriorated. If the fermentation period is less than 3 months, the fermentation does not proceed sufficiently and the fermentation tends to be decayed, so that it is not suitable for use as a feed composition. If the fermentation period exceeds 12 months, acetic acid fermentation or alcohol fermentation may proceed and corruption may proceed depending on the storage place or environment. The fermentation period of 6 months to 12 months does not affect the storage condition of the fermented product. However, when the fermented product is used as a feed composition, the use of the fermented product within 6 months can further improve the quality of livestock meat. Cost can also be reduced.

The saccharides used in preparing the fermented product of Omija can be any sweet taste, but preferably at least one selected from the group consisting of sugar, sugar powder, oligosaccharide, agave syrup, maple syrup, cactus sugar and honey It is preferable to select a saccharide.

It is preferable that the by-product of the fermentation product of the Schizandra chinensis can be contained in the livestock feed composition in an amount of preferably 0.1 to 0.3% by weight. When the by-product of the fermentation product of Omija fermented product is mixed at less than 0.1% by weight based on 100% by weight of the animal feed composition, the effect of promoting the growth of the livestock hardly occurs and the quality of the meat of the livestock is not improved. In addition, when the content exceeds 0.3% by weight, the quality of meat of the livestock may be deteriorated.

It is preferable that the fermentation temperature of the fermented product of Omija fermentation is 4 to 37 캜. Preferably 15 to 30 占 폚.

The livestock feed composition may be prepared by mixing the by-product of the fermentation product with the nutritional formula. Preferably, the animal feed composition is a mixture of a by-product of the fermented product of Omija and a nutritional supplement feed. It is preferable that the nutritive composition feed contains 99.7 to 99.9% by weight based on 100% by weight of the whole livestock feed composition.

The nutritive compound feed is a commonly used compound feed containing proper nutrients in order to maintain the health of the livestock and to fully exhibit the production capacity of the livestock. can do.

It is also possible to add other functional ingredients to the animal feed composition. However, it is preferable to reduce the content of the nutritional formula by the amount of the functional ingredient added. The content of the functional ingredient is not limited, but is preferably 1 to 30% by weight based on 100% by weight of the whole livestock feed composition. As the functional ingredient, any of common vegetable raw materials and animal raw materials that can be added to the livestock feed composition can be used.

The present invention relates to a livestock feed composition containing a by-product of an omelet sugar fermented product. The livestock feed composition can be recycled as a by-product of the fermented product of Omija fermented by the food waste, which is eco-friendly. In addition, since the by-product of the fermented product of Omija perilla is directly mixed with the nutrient-containing feed without further processing for the production of the feed composition, the feed composition is easily manufactured and the production cost is very low.

< Experimental Example  1. Chickens breeding and Weight gain , Feed intake, feed efficiency>

Experimental Example 1-1. Chickens Breeding and Weight Gain, Feed Intake, Feed Efficiency

Specimens were tested for chickens using the feed compositions prepared in Example 2 and Comparative Example 2. [ The chicks used in this experiment were three weight-average Ross broiler chickens and 15 chickens per each sample group. At this time, only the nutritional formula was fed to the control group.

The feed compositions of the above conditions were fed to the chicks for 35 days, and then the weight gain, feed composition intake, and feed efficiency of the chicks were checked during this period. The feed intake was determined by measuring the remaining amount of the feed composition before the body weight measurement by the treatments every week from the start to the end of the test, and the feed efficiency was obtained by dividing the feed intake by the body weight gain.

Feed composition feeding condition Feed composition intake (g) Weight gain (g) Feed efficiency (ratio) Example 2-1 3332.52 2156.07 1.55 Example 2-2 3253.34 2174.43 1.50 Example 2-3 3243.45 2153.52 1.51 Comparative Example 2-1 3845.97 2085.67 1.84 Comparative Example 2-2 3278.84 1863.56 1.76 Comparative Example 2-3 3296.56 1847.23 1.78 Comparative Example 2-4 3167.56 1703.85 1.84 Comparative Example 2-5 3166.23 1718.77 1.86 Comparative Example 2-6 3307.99 1956.85 1.69 Comparative Example 2-7 3389.07 1996.67 1.70 Control group 3243.85 1754.96 1.85

As shown in Table 4, the feed composition according to Example 2 of the present invention showed significantly higher feed efficiency than that of the feed composition of Comparative Example 2 or the feed supplemented only with the nutritional formula, appear. In the group fed with the feed composition of Comparative Example 2-1 containing the by-product of Omija without the saccharide component, the feed intake was high, but the amount of the body weight was not increased so much that the feed efficiency was not good. It can be seen that the feed efficiency of the group fed with the fermented feed of the Comparative Example 2-2 and the Comparative Example 2-3 was not increased compared with the feed intake of the group fed with the fermented omiza bark. The feed intake of the feed compositions of Comparative Example 2-4 and Comparative Example 2-5, which contained Schizandra chinensis and Schizandra chinensis juice, had a very low feed intake and no better feed efficiency than the control group. As a result, it can be seen that the use of unprocessed Omiza or Omiza bark directly reduces the preference for the feed. In addition, although the by-product of the fermented product of Omija fermented milk was improved compared to the control group in which the feed composition of Comparative Examples 2-6 and 2-7, in which the by-product of the fermented milk of Omija fermented product was mixed with 0.1-0.3 wt% based on 100 wt% of the whole feed composition, This was not good.

<Experimental Example 2> Determination of the body weight gain, feed intake and feed efficiency of ducks and ducks>

The ducks were fed for 6 weeks using the feed compositions of Example 2 and Comparative Example 2. At this time, only the nutritional formula was fed to the control group. The ducks used in this test were the ducks with an average weight of 85 to 90 g, and the feed composition was fed at a rate of 7 mice per group. At this time, feeds were fed unlimitedly and water was allowed to free.

The weight of ducks was measured every week from the start to the end of the test. The amount of feed composition was measured from the beginning to the end of the test, and the amount of feed composition was measured by measuring the remaining amount of the feed composition before the body weight measurement, and the feed efficiency was obtained by dividing the feed intake by the body weight gain. The productivity evaluation results of the above duck specimen test are shown in Table 5 below.

Feed composition feeding condition Feed composition intake (g) Weight gain (g) Feed efficiency (ratio) Example 2-1 7623.74 3585.74 2.13 Example 2-2 7652.84 3667.56 2.09 Example 2-3 7663.57 3596.89 2.13 Comparative Example 2-1 7934.64 3307.56 2.40 Comparative Example 2-2 7685.59 3323.67 2.31 Comparative Example 2-3 7645.76 3284.70 2.33 Comparative Example 2-4 7364.47 2935.38 2.51 Comparative Example 2-5 7362.23 2931.99 2.51 Comparative Example 2-6 7656.88 3145.47 2.43 Comparative Example 2-7 7645.48 3223.58 2.37 Control group 7654.74 3163.63 2.42

As can be seen from Table 5, in the feeding of the ducks, the feed composition feeding group of Example 2 of the present invention was significantly increased in weight gain compared with the feed composition feeding group of Comparative Example 2 or the feeding group of only the nutritional formula feed Feed efficiency is shown to be excellent (feed efficiency is better as the value is lower). In the group fed with the feed composition of Comparative Example 2-1 containing the omega by-products without sugar components, the feed intake was high as in the case of the chicken feed, but the feed efficiency was not so high because the amount of the feed was not significantly increased. It can be seen that the feed efficiency of the group fed with the fermented feed of the Comparative Example 2-2 and the Comparative Example 2-3 was not increased compared with the feed intake of the group fed with the fermented omiza bark. The feed composition of Comparative Example 2-4 and Comparative Example 2-5 containing omiga mackerel and omija juice had lower feed intake and lower feed efficiency than the control group as in chicken feed. In addition, the feed compositions of Comparative Examples 2-6 and 2-7 in which the by-product of the fermentation product of Omija fermented product was mixed with 0.1-0.3 wt% based on 100 wt% of the whole feed composition were also improved, but the feed efficiency was improved Can not.

<Experimental Example 3> Confirming meat quality of chicken meat>

Using the feed composition of Example 2 and Comparative Example 2, feeding was started to 10 days old 3-day-old Korean chickens per group, and at the age of 5 months, six chickens were selected for each group The constituents of chicken were analyzed. In addition, the meat samples and chest meat were sampled immediately after slaughtering, and the meat samples were crushed into meat products. The samples were analyzed for heating loss, water holding capacity, shear force, general composition (moisture, crude protein, crude fat, (Saturated fatty acid, unsaturated fatty acid) were analyzed by the general component test method and micro nutritional method according to the Food Code (2005) by the National Livestock Research Institute of RDA. The results are shown in Tables 6 to 8.
