Hereinafter, the present invention will be described in more detail.

The present invention provides a concentrated feed having increased palatability of poultry including chicken by applying or coating the coating material on the granule or flake surface while using the hydrolyzate of mesocarp as a byproduct of the palm oil manufacturing process as a main ingredient.

The mesocarp hydrolyzate used in the present invention is a hydrolyzed carbohydrate obtained by hydrolyzing a moist and soft portion discharged from a decanter in a wet process of palm oil with a cellulase or a cellulase combination preparation. It is similar to that published in. In addition, the concentrated feed having enhanced palatability of the poultry containing poultry of the present invention is similar to that of the concentrated feed for livestock breeding produced by mixing and granulating various kinds of cereals as a sub ingredient in the palm fructus enzyme hydrolyzate presented in the patent .

However, in the present invention, a part of the supplementary material added to supplement the insufficient nutrients of the palm kernel hydrolyzate is applied or coated on the surface of the feed granule or flake before the completion as a coating material, The present invention provides an advanced concentrated feed having improved palatability more than twice and a method for producing the same.

In the present invention, the coating material powdered or coated on the surface of the granules or flakes containing the palm kernel hydrolyzate as the main raw material includes most materials for producing feeds except the hydrolyzed enzymes of palm flesh. Examples include, but are not limited to, cereals including corn, sorghum, rice, barley, wheat and oats, starches including soybeans, sunflowers, palms, palm kernels, starches containing sweet potatoes, potatoes, And powders of at least one material selected from the group consisting of pulp or steel produced during the processing of the cereals, oils, and starch sources, and powder of at least one material selected from the group consisting of palm oil. In consideration of the composition of nutrients, soybean meal, corn, , Palm kernel mill and the like are more preferable.

In the present invention, a coating material for covering or covering the surface of a granule or a flake whose main ingredient is a palm kernel hydrolyzate is a powder obtained by pulverizing and drying the dried material for producing a feed, and the powder is coated on the surface of a feed granule or a flake It is desirable to have a powdery degree within a range without interference. As an example of such a method, dried corn is ground with a food pulverizer having a 20-mesh sieve. In the case of rice bran, however, the by-product generated after the rice may be used as a coating material.

In the present invention, the coating material for covering or covering the surface of the granule or flake containing the palm kernel hydrolyzate as the main raw material is a final product containing about 10% of moisture, and it is a final product containing 1 to 10% , And it is more preferable to use the feed within the range of 1 to 5%, considering that the feed supplied with fine powder is somewhat reduced in terms of the intake rate of poultry including chickens. The amount of the coating material to be added is increased when the granules or flakes to be coated or coated with a large amount of water and the amount of the coating material which can be adhered when the amount of water to be coated is low is low, However, there is no significant effect on the palatability of poultry including chicken after the production of feed.

The present invention further provides a method for producing a concentrated feed for livestock breeding in which a coating material is coated or coated on a granule or a flake surface in order to improve the palatability of poultry including chickens while using palm kernel hydrolyzate as a main raw material. That is, the method of producing a concentrated feed of the present invention can be presented as follows.

1) a step of semi-drying the palm kernel hydrolyzate to adjust the cellulase hydrolyzate of mesocarp, which is a by-product of the palm oil production process, to a water content of 10 to 30%

2) adding the at least one selected from the group consisting of vitamin premix, mineral premix, lysine, feed antibiotic, and feed additive to the semi-dried palm kernel hydrolyzate through the semi-drying step;

3) a granulation step of granulating the mixture of the palm fermentation semi-product or the palm pulp semi-product with the additive into a granulator, or further grinding to prepare a flake,

4) granulating or flaking the granules or flakes prepared through the granulation step, mixing or coating the powder or the coating material with the coating material,

5) drying the granules or flakes in a hot air dryer and sealing and packaging

In a method for producing a concentrated feed for livestock breeding in which a coating material is coated or coated on a granule or a flake surface in order to improve the palatability of poultry including chickens while using the palm pulp hydrolyzate of the present invention as a main raw material, the first step 1) The hydrolyzate of palm kernel is prepared by the method described in Korean Patent No. 1408840 and semi-dried to adjust the moisture content to 10 to 30%. In the palm oil production process, the palm pulp discharged from the decanter to the sludge used for the separation of oil and pulp already contains a large amount of water, and the hydrolyzate produced by hydrolysis thereof into cellulase contains more than 80% of water. On the palm fruit variety can be used in the dryer, but the examples include a rotary dryer and crushed stirring dryer or the like, the thermal efficiency nopeumyeonseo dried form suitable for drying in order to dry the hydrolyzed number is large, the viscosity moisture material 140 ^o C It is not particularly limited as long as it does not exert such heat. The semi-product obtained through this step preferably has a moisture content of 30% or less so as to allow uniform mixing when the additive mixture of step 2, which is mixed in powder form, is added and mixed again. The drying process of the palm kernel hydrolyzate should be undertaken as soon as possible after discharge from the hydrolyzers to prevent microbial contamination and propagation and should be performed at as low a temperature as possible to minimize pyrolysis of the nutrients. Therefore, the palm kernel hydrolyzate is preferably dried at a temperature of 40 to 140 ^° C, more preferably at 50 to 105 ^° C. The drying time is not particularly limited as long as the thermal efficiency can be increased while avoiding the occurrence of microorganisms.

In the method for producing a concentrated feed for livestock breeding in which a coating material is coated or coated on a granule or a flake surface in order to improve the palatability of poultry including chickens while using the palm pulp hydrolyzate of the present invention as a main ingredient, Is mixed with an additive to supplement the insufficient component. That is, in order to compensate for insufficient nutrients, an additive mixture is prepared by mixing soybean meal, corn powder, lysine, vitamin premix, inorganic premix, feed antibiotic, feed additive, etc., The method and equipment are not particularly limited.

In addition, if necessary, the additive may be supplemented with a feedstuff consisting of ordinary feed products or a flavoring feed containing a flavoring agent and a sweetening agent. However, in the case of a concentrated feed prepared by coating or coating the coating material composed of soybean meal, corn, rice gruel, cassava, and palm kernel mill described below with the granular or flake surface of the palm flesh hydrolyzate, The feed intake of poultry is greatly increased without mixing flavor feeds containing flavorings or sweeteners, and productivity of eggs and meat of poultry is greatly improved. Therefore, there is an advantage that such a dietary feed or flavor feed is not additionally used as an additive.

In a method for producing a concentrated feed in which a coating material is dispersed or coated on a granule or a flake surface in order to improve the palatability of poultry containing chicken as a main ingredient of the palm flesh hydrolyzate of the present invention, Granulating the granules by a granulator, or grinding the granules to produce flakes. This process is not particularly limited, since conventional granule or flake manufacturing technology can be applied as it is.

In a method for producing a concentrated feed in which a coating material is dispersed or coated on a granule or a flake surface in order to improve the palatability of a poultry containing chicken as a main ingredient of the palm flesh hydrolyzate of the present invention, Or applying the coating material to the flakes and spraying or coating them. At this stage, the coating material can be dispensed by adding 5% or less of the coating material and lightly mixing for a short period of time, and the coating material can be applied to the granules or flakes so as to be thick enough close to the coating material by increasing the amount of the coating material and increasing the mixing time . The mixer used here is more suitable as a concrete mixer than a model in which the blades run inside, but any device capable of mixing granules and powder for a relatively short period of time is acceptable.

In a method for producing a concentrated feed in which a coating material is dispersed or coated on a granule or a flake surface in order to enhance the palatability of a poultry containing chicken as a main ingredient of the palm flesh hydrolyzate of the present invention, This is a process of drying and sealing the coated granules or flakes. The granules or flakes prepared in step 4 may contain more than 10% of water, so it is advisable to dry the granules so that the granules are hardened and the moisture content is 5 to 10% by blowing hot air to prevent deterioration during storage. The dry granulated or flake-shaped feed can be finished by making sealed packing with an unattached powder-form applicator.

Hereinafter, the present invention will be described in more detail based on the following examples. However, the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example 1: Preparation of concentrated feed treated with powder of corn powder

In the process of manufacturing palm oil, 10,000 g of the palm pulp discharged from the decanter was converted into a building, and 200 ml of Cellic CTec2 (Novozymes Korea, Seoul) as a cellulase was added to the 75-liter fermenter. The hydrolyzate was hydrolyzed for 12 hours while maintaining a temperature of 50 ± 1 and a pH of 5.0 ± 0.3. This was put in a 5-liter rectangular tray and dried in an oven at 60 to 80 ° C to produce a palm kernel enzyme hydrolyzate, which is the main raw material for producing a feed having a moisture content of about 25%. In a palm fleshy building, 1,400 g of palm kernel hydrolyzate was added to a free stirrer, mixed with 266 g of cassava powder and heated at 105 ° C for 40 minutes to remove the liquid. 8.9 g of feed additive lysine (Kwangwang Industry Co., Kunsan), 4.4 g of vitamin premix for feed additive (Wonsung Company, Nonsan) and 4.4 g of mineral premix (Woosung Products, Nonsan) were added and uniformly mixed to prepare granules Was prepared. This mixture was put into an extrusion granulator and granulated with a diameter of 3 mm and a length of 1 to 5 mm to prepare granules for granulation.

The granule for granulation was transferred to a mixer, and 88.6 g of corn powder was added thereto, followed by mixing for 5 minutes, followed by drying in a hot air drier at 50 ° C until the moisture content was 5 to 10%. The dried feed was divided into silver foil bags and heat sealed to complete the concentrated feed.

Examples 2 to 4: Preparation of concentrated feed treated with powder of palm kernel wheat, raw beef steel, and cassava powder

(Example 2), raw fish (Example 3) and cassava (Example 4) powders, which were the same amounts as the corn powder instead of the corn powder, were added to the mixer in the same manner as in Example 1 Enriched feeds, each added as a coating material, were prepared and used in the chick biteability test.

Control Example 1: Production of concentrated feed without application of coating material

The granule granules of Example 1 were directly poured into a hot air dryer at 50 캜 and dried until a moisture content of 5 to 10% was obtained. Then, the granules were divided and packed in a vat and heat sealed to complete a concentrated feed. This feed was used as a control feed in the chickens brisk test.

Test Example 1: Chickenship test of concentrated feed

Twenty birds were added to each of two houses of 2m, 2m, and 2.5m in length, height, and height, respectively, for 3 weeks. One commercial feed was fed and fed for 1 week to adapt to the environment. Four treatments of the concentrate feeds of Examples 1 to 4 and one control feed of Control Example 1 were each divided into two groups of 400 g each in a feed tray to prepare food. At 9:00 am, four containers of the concentrated feed of Example 1 and one control feed of Control Example 1 were repeatedly fed to each house and the food was eaten, and then the food tray was collected at 6:00 PM. From the remaining feed weights, the amount of feed already consumed was calculated, and the average of the two cage measurements was calculated to calculate the feed uptake rate.

Feed classification The intake (g) Intake rate (%) Control Example 1 Do not process the coating material 110 ± 29 27.5 Example 1 Treatment of corn powder 216 ± 15 54.0 Example 2 Treatment of Palm Kernel Wheat Powder Powder 213 ± 21 53.3 Example 3 Treatment of raw ore powder 197 ± 12 49.3 Example 4 Treatment of cassava powder 195 ± 35 48.8

As shown in the above Table 1, after the conventional concentrated feed made from the palm kernel hydrolyzate as a raw material is made into granules or flakes, a powder of several feed ingredients is granulated or coated on the surface of granules or flakes to form a separate flavoring agent The feed intake ratio of at least 1.7 to 2 times higher than that of conventional feeds containing palm kernel hydrolysates was increased without the addition of sweeteners containing sweeteners.

Particularly, the granular granules of Control Example 1 are concentrated feeds prepared by mixing a semi-dried mixture of palm fructus enzyme hydrolyzate and cassava powder as the main raw material, and this is the same as that of the above-described Korean Patent No. 1408840 Compared with Control Example 1 and Examples 1 to 4 of the present invention, the present invention is characterized in that the concentrated feed disclosed in the Korean registered patent corresponds to chicken The present inventors have found that the use of the hydrolysates of the palm fructus enzymes according to the present invention is effective in improving the palatability of poultry including chickens It can be confirmed that it can be a good effective feed.
