Description

[0001] The present invention relates to a feedstuff composition containing powdered red shale and rare earth elements,

The present invention relates to a livestock feed composition containing a red shale powder, a rare earth element compound and a nutritional compound feed.

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, antibiotic resistance is produced in livestock due to the high concentration of antibiotics used, and human consumption of livestock products (meat, milk, eggs, etc.) obtained from these livestock can cause antibiotic resistance in humans, ≪ / RTI > In order to overcome this problem, studies on various functional foods and eco-friendly agents that can replace antibiotics have been conducted. However, these materials are often expensive materials. When they are added to livestock feed, And thus the utilization rate thereof as a feed additive was not high.

Shale is a type of mudstone, also called shale. The shale has a property of thinning in a certain direction, which is a primary one due to the arrangement of particles in parallel with stratification or foliage. In contrast, it is said to be slate cancer that the secondary release surface is formed by pressure after sedimentation. Shale is divided into black shale and red shale depending on the color, and it is classified into corrosion shale (also called humic shale [humus shale], humic acid is abundant) according to the contained ingredients.

The black shale is abundant in animal organic matter, and it is black because it is hardly oxidized compared to the red shale. Black shale is mainly distributed in areas rich in crude oil reserves. Corrosion shales are abundant in vegetable organic matter because they are formed by hardening of soils deposited in mountains or fields. Corrosion shale is often used as a fertilizer additive.

The red shale is formed by hardening the soil deposited from the sea, and the amount of organic matter is small and the oxidation progresses to a red color. The shale in Korea is mainly red shale. The red shale is a porous fine powder and has very strong adsorption power and is known to have a surface area as large as about 20,000 times as large as the surface area of activated carbon. Therefore, studies have been made to adsorb harmful bacteria such as Escherichia coli, which parasitize in the intestines of the livestock, and heavy metals such as mercury or cadmium by such strong adsorption power. It is also known that red shale contains many more minerals than elvan.

The Rare Earth Elements are a total of 17 elements including 15 lanthanum elements (element numbers 57 to 71), scandium (Sc) 21, and yttrium (Y) number 39 . Rare earths are rarely produced in enriched forms because they are economically viable due to the geochemical nature of the material, and rare in the form of minerals. Thus, rare earths have been named as "rare earth metals" in the natural world. But in reality, rare earths are buried abundantly on earth relative to their names. For example, cerium with an atomic number of 58 is 68 ppm, the 25th most abundant element in the earth's crust. In the case of thulium and lutetium, which are known to have the lowest reserves among the rare earths, cerium has more than 200 times more reserves than gold. Rare earths are chemically very stable, well tolerated in dry air, characterized by good thermal conduction and relatively good chemical, electrical, magnetic, and luminescent properties. In recent years, it has also been known that it has excellent adsorbability and has been used as a feed additive or a fertilizer additive.

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 .

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

The feed composition prepared in Example 3 and Comparative Example 1 was used to perform a specification test on chickens. 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 the amount of body weight gain, feed composition intake and feed efficiency of the chicks during the period were checked. 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.

As shown in Table 5, the dietary feed composition of Example 3 of the present invention showed almost no difference in the amount of feed composition compared to the feed composition of Comparative Example 1 or the feed supplemented only with the nutritional formula, And the feed efficiency is improved.

Experimental Example 1-2. Check meat quality of chicken

The crude fat contents, crude protein content, shear force, etc. of the chicken were slaughtered in the experiment example 1-1, and the results are shown in Table 6.

The crude fat content and crude protein content of chicken were analyzed after 5 treatments per treatment group of chickens close to the average weight in each treatment immediately after the end of the specification test. Fat and protein content were analyzed according to the AOAC (1995) method by using meat and poultry meat, respectively, just after slaughtering.

The shear force of the chicken was measured by cutting the breast into stakes, heating the meat inside temperature to 80 ° C in a constant temperature water bath after 1 hour, collecting the sample in the direction of the muscle fiber with a core of 0.5 inches in diameter, (Warner-Bratzler shear force meter, USA). The measurement was carried out by placing the sample vertically in the lower part of the inner bottom of the diamond-shaped blade, hollowed out, and cutting the sample down while operating the machine. The force received was measured by shear force.

As can be seen from Table 6, crude fat content of the chicken group using the feed composition of Example 3 and Comparative Example 1 was lower than that of the control group, and the crude protein content was the same as that of the feed composition of Example 3 Of chicken meat. As a result of measuring the amount of force (shear force) at the time of cutting the treated chicken, it was confirmed that the group using the feed composition of Example 3 could produce soft meat having a lower shear force as compared with the control group.

<Experimental Example 2> Confirmation of disease resistance of chicks>

The feed compositions of Example 3 and Comparative Example 1 were fed to a Ross broiler chick for 20 days at 10 rats per group for 2 weeks and then Salmonella gallinarum was cultured. The number of strains was adjusted to be 1 x 10 ⁹ CFU / ml using saline solution, and then the solution was orally administered by 1 ml each. At this time, only the nutritional formula was fed to the control group. Thereafter, the survival rate of the chicken was confirmed while feeding the feed composition in the same manner for 15 days, and the results are shown in Table 7.

As shown in the results of Table 7, it was found that all the chicks survived despite the administration of the Salmonella strain in the group fed with the feed composition of Example 1 of the present invention. However, in the group fed with the feed composition of Comparative Example 1 Or in the control group fed only with nutritional formula, 30 to 50% of the chicks died in 15 days (untreated Salmonella strain in the same conditions, 100% of the chicks fed only with nutrient supplementation survived).

<Experimental Example 3: Evaluation of immunity against chick>

The feed compositions of Example 3 and Comparative Example 1 were fed to a Ross broiler chick for 20 weeks at 6 rats per group for 2 weeks and then evaluated for the lysozyme activity in the serum of chicks. Blood was collected from the chick's wing veins. At this time, only the nutritional formula was fed to the control group. Serum was separated by centrifugation (4 ° C, 2,000 × g) using a centrifuge for 10 minutes and used for the measurement of lysozyme activity. Preparation of lysozyme activity standard solution was performed by dissolving crystalline lysozyme (Sigma-Aldrich, St. Louis, MO, USA) in phosphate buffer (pH 6.2) at 0.5, 1.0, 2.0, 3.0, 4.0 , 5.0 or 6.0 占 퐂 / ml to prepare a standard solution. Subsequently, 20 μl of each concentration solution was filled into a 96-well microtiter plate, 200 μl of phosphate buffer was added to one well, and 200 μl of microcococcus Lyso was added to the other well. 200 쨉 l of a solution of Micrococcus lysodeikticus (600 mg / l, Sigma-Aldrich, dissolved in phosphate buffer) was added. After incubation at 41 ° C for 15, 30, 45 and 60 minutes, the absorbance was measured at 540 nm and the regression coefficient (b) between absorbance and time was calculated. Serum samples were treated in the same manner as standard solutions. The activity of lysozyme was measured based on the correlation between the coefficient b and the lysozyme concentration.

For the measurement of lysozyme activity of spleen, all chicks were sacrificed by cervical dislocation and the spleen was removed. The fat and membrane were removed and the spleen tissue (0.5 g) was homogenized in 5 ml of cold PBS (phosphate buffered saline). The homogenate was diluted to a concentration of 1 mg / ml and the lysozyme activity of the diluted homogenate was measured by the same method as serum. The lysozyme activity results are shown in Table 8.

As a result of measuring the activity of lysozyme having a strong antimicrobial effect against peptidoglycan of Gram-positive bacteria, the concentration of serum lysozyme in the group fed with the feed composition of Example 3 was higher than that of Comparative Example 1 &lt; / RTI &gt; feed composition or the nutrient supplemented feed alone. Likewise, the concentration of spleen lysozyme in the group fed with the feed composition of Example 1 was significantly higher than that of the group fed with the feed composition of Comparative Example 1 or the group fed only with the nutritional formula.

EXPERIMENTAL EXAMPLE 4. Determination of Freshness of Egg Egg White Egg

Eggs of these chickens were collected on the same day after feeding for 10 days in each of 10 eggs of Example 3, Comparative Example 1 and a 30-week old high-line hen which actively raises eggs with commercially available organic feeds. The eggs were collected at room temperature for 13 days Respectively. At this time, only the nutritional formula was fed to the control group. Thereafter, the bag and the yolk breaking the egg were dropped on a plate, and the average diameter of the egg white was checked to measure the freshness of the egg. The longer the storage time of eggs, the lower the freshness of eggs and the lower the cohesiveness. If you break the egg with such a freshness and pour the contents on a flat surface, the egg white tends to spread more widely. The eggs used in the experiment were randomly selected from six eggs produced on the same day by each group of chickens, and the results are shown in Table 9.

Referring to Table 9, it can be seen that the chicken egg-bearing egg of the feed composition of Example 3 of the present invention was fed with egg white diameter or nutritionally mixed feed of egg produced by chicken fed with the feed composition of Comparative Example 1 It was confirmed that the feed composition of the present invention had an effect on the freshness of the eggs. In addition, the results were much better than those of chicken eggs produced with commercial organic feeds.

< Experimental Example  5. Prevention of avian influenza>

The feed composition of Example 3-1 was fed to chickens raised in poultry farms. As a result, when birds were infected with bird flu in all of the surrounding poultry farms, all birds were killed, and no avian influenza virus occurred in the chicken of this farm where the feed composition of Example 3-1 was fed.

< Experimental Example  6. Duck breeding and duck Weight gain , Feed intake, feed efficiency>

The ducks were fed for 6 weeks using the feed composition of Example 3 and Comparative Example 1. 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, the feeds were fed unlimitedly and water was freely consumed.

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 10 below.

As shown in Table 10 above, the feeding composition of Example 3 of the present invention showed almost the same dietary intake as that of the feed composition of Comparative Example 1 or the feeding composition of only the nutritional formula, Although not excreted, the amount of weight gain is remarkably increased, indicating that the feed efficiency is excellent.

< Experimental Example  7. Non-livestock evaluation of cows>

Ten Holstein cows of 30 to 40 months of age were prepared for each group. At this time, cows with good health status and similar body weight and physical condition were selected as experimental subjects. The feed compositions of Example 4 and Comparative Example 2 were fed to selected dairy cows for 3 weeks and milk yield, nutrients in milk and somatic cell counts in milk were compared and the results are shown in Table 11. The control group was fed only nutritional formula. On the other hand, since the number of somatic cells per unit density increases in milk of cow afflicted with mastitis or breast cancer, the decrease of somatic cell count is an important factor in milk quality.

Condition Milk yield

(cells / ml) Example 4-1 29.5 5.23 3.65 4.65 69,453 Example 4-2 28.9 5.14 3.57 4.75 66,960 Example 4-3 29.6 4.97 3.54 4.78 63,699 Example 4-4 28.6 4.89 3.55 4.65 63,345 Example 4-5 28.7 5.05 3.57 4.66 64,377 Examples 4-6 28.8 5.04 3.64 4.65 63,447 Examples 4-7 29.6 5.13 3.55 4.64 66,170 Comparative Example 2-1 28.9 4.96 3.29 4.57 129,026 Comparative Example 2-2 29.6 4.83 3.27 4.56 184,634 Comparative Example 2-3 28.7 4.92 3.12 4.55 175,753 Comparative Example 2-4 29.8 5.05 3.15 4.64 136,974 Comparative Example 2-5 28.6 5.12 3.28 4.57 127,205 Control group 28.1 4.86 3.14 4.55 207,666

As can be seen from the results shown in Table 11, the feed composition of Example 4 of the present invention showed little difference in milk production compared to the feed composition of Comparative Example 2 or the feed of only the nutritional formula, The contents of milk fat and lactose were similar. However, it can be confirmed that the feed composition of the feed composition of Example 4 has a higher milk protein content and significantly reduced the number of somatic cells, thereby remarkably improving milk quality.
