Description

{Cattle feed using expander}

More particularly, the present invention relates to a feed for breeding stock using an expander, and more particularly, to a method of breeding a feed for breeding wastes, comprising the steps of subjecting each raw material to high temperature and high pressure once, The present invention relates to a feed for breeding cattle using an expander capable of improving the use amount of low-priced raw materials and improving the feed preference and meat quality of the breeding.

Generally, when feeding livestock such as cattle, pigs, and chickens, feed is fed. These feeds include raw materials such as corn, wheat, wheat, wheat bran, soybean meal, coconut, palm, flax, Is used. However, the raw materials are high in fiber, so the digestibility of livestock is low. In particular, pigs and chickens, which are unit animals, are at risk even when they consume high fiber raw materials as they are.

Therefore, in order to improve the quality of these feeds, the crushing (ie, particle size control) processing of grains has been shown to improve the digestibility of nutrients when the particle size is reduced (1932, Tex. Its importance has begun to emerge since its reporting.

The effect of grain size control on nutrient digestibility is expected to improve nutrient digestibility by reducing the grain size of feeds used as feedstock for corn, sorghum and barley (Lawrence TLJ, Anim. Prod., 1970, 12: 139) .

Thus, it is absolutely necessary to increase the utilization of nutrients in livestock production, and with the development of processing techniques (grinding, pelletizing, steam-frying, roasting, extrusion and expansion), nutrient availability Has been improved.

Crushing, which can be done primarily before compounding the feeds, is the most widely used processing method and is a method of reducing the particle size of the feed material by using a hammer mill or a roller mill. This increases the surface area of the cereals during the feeding of the feed, which increases the digestive enzymes' interactions in the intestines of the animal. As a result, it improves the digestibility of the nutrients and prevents the separation phenomenon in the feed mixture. As a processing method, many researchers (Roth FX et al., Zentrallbl. Vet. Med., 1985, A (32): 692-698; Potkins ZV and Lawrence TLJ, Res. 74, Elbers AR, et al., Vet. Rec., 1995, 137: 290-293).

Pellet feeds are made by pelletizing a powdered feed at a constant temperature (60-80 ° C) and pressure (1.5-2 kg / m 2) into a pellet of uniform size, and crumble is a pellet Is passed through a crumbling machine and crushed into pieces of a certain size. In the processing of feed, starch particles in feed are hydrolyzed to increase the digestibility of carbohydrates, proteases easily work to increase the digestibility, and the digestibility of crude fiber also increases.

Animals are reported to prefer pellet feed to powdered feed (Vanschoubroeck, F. et al., Nutr. Abstr. Rev., 1971, 41: 1-9) And protein digestibility is improved by 3.7%. Processing with expanders and extruders has the effect of widening the choice of raw feed and increasing the quality of the pellets.

Korean Patent No. 10-1348228 discloses an apparatus and a method for manufacturing fermented fiber based on palm processing by-products, and Korean Patent No. 10-1447414 discloses a feed composition and a manufacturing method thereof However, since the various raw materials are respectively pulverized and mixed, they are added to the expander, and they are produced in the form of powder. Therefore, the pelletization process is added to perform the expander twice. As the expander is performed twice, And the palm and palm leaves have low basic digestibility and can not significantly improve digestibility even though the raw materials are inexpensive.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to shorten the process by increasing the production efficiency by mixing the raw materials after subjecting each raw material to high temperature and high pressure once, It is an object of the present invention to provide a fodder using an expander which can remarkably improve the digestibility and can increase the amount of low-priced raw materials and improve the fodder preference and meat quality of females.

In order to achieve the above-mentioned object, the present invention provides a soybean meal comprising 23 to 25 parts by weight of soybean meal, 18 to 20 parts by weight of a seedling foil, 45 to 50 parts by weight of a palmate, 23 to 25 parts by weight of a main anchoring, 45 to 50 parts by weight of limestone and 4 to 5 parts by weight of limestone. The corn, the soybean meal, the seedling oil, the palm, the main anchovy and the palm kernel are each pulverized to 2 to 4 mm, And the mixture is expanded once for 2 to 4 seconds at a pressure of 3.5 to 5 kg / m 2 and then mixed to have a digestibility of 80 to 95%.

The feed of the fodder using the expander according to the present invention as described above can reduce the production cost and increase the production efficiency by shortening the process by mixing the raw materials of each raw material at a high temperature and high pressure once after performing the expanding process once It is effective.

It also has the effect of high sterilization effect and high digestibility.

In addition, the digestibility can be remarkably improved to improve the palatability of meat and the meat quality of the meat, and the production period to slaughter can be shortened to increase the production efficiency.

In addition, since the fiber feed digestibility of the fowl can be increased, the dosage of the fibrous raw material can be increased as compared with the conventional method, and the inexpensive raw materials such as palm leaves and palm fronds can be manufactured as high quality feeds, .

In addition, the present invention has an effect that the mixing accuracy of the granular feedstock mixed with other raw materials is excellent when granulated after the extender.

Hereinafter, preferred embodiments of the present invention will be described in detail. These examples are for further illustrating the present invention, and the scope of rights of the present invention is not limited to these examples.

The fodder using the expander according to the present invention comprises 23 to 25 parts by weight of soybean meal, 18 to 20 parts by weight of a seed meal, 45 to 50 parts by weight of a femmate, 23 to 25 parts by weight of a main anchovy, 45 to 50 And 4 to 5 parts by weight of limestone.

At this time, the corn, soybean meal, soybean meal, palm, main anchovy, and palm fronds are each put into a storage tank for each raw material, ground to 2 to 4 mm, introduced into an expander, expanded once, 23 to 25 parts by weight of soybean meal, 18 to 20 parts by weight of soybean meal, 45 to 50 parts by weight of females, 45 to 50 parts by weight of coconut husk, 100 to 5 parts by weight of corn, And 4 to 5 parts by weight of limestone.

It is needless to say that lactic acid bacteria or vitamins may be further added to enhance the functionality of the fodder using the expander.

The expander inflates the raw materials at a temperature of 160 to 180 占 폚 at a pressure of 3.5 to 5 kg / m2 for 2 to 4 seconds.

In the past, pelletizing process was added to the conventional extruder, so that the extender was extruded at a temperature of 60 to 80 ° C at a pressure of 1.5 to 2 kg / m 2 twice The present invention is characterized in that after each raw material is pulverized, the extender is once subjected to a pressure of 3.5 to 5 kg / m < 2 > at a temperature of 160 to 180 DEG C for 2 to 4 seconds and mixed, It has an effect of high sterilizing effect and high digestibility.

In addition, by performing the expander only once, it is possible to reduce the power cost, thereby reducing the production cost.

Also, conventionally, a pelletization process is carried out by using a vibrator to remove powder that has not been pelletized, and pelletizing the removed powder again. Since the present invention has no pelletization process, the process is shortened and production efficiency is increased It is effective.

In addition, the present invention has an effect that the mixing accuracy of the granular feedstock mixed with other raw materials is excellent when granulated after the extender.

In addition, the digestibility of the poultry feed thus prepared is improved to 80 ~ 95% with the digestibility being improved, so that palatability and meat quality of the poultry can be improved.

Since the fiber feed digestibility of the fowl can be increased, it is possible to increase the dosage of the fibrous raw material, and it is possible to manufacture the low cost raw materials such as palm leaves and palm leaves as high quality feeds, .

< Example  1> Expander  Production of used cattle feed

Prepare corn, soybean meal, soybean paste, palm, main anchovy, coconut cake, and limestone, which are raw materials of the feed for sowing. At this time, the limestone is prepared in powder form.

The following procedure is carried out for each raw material in the prepared raw materials, namely, corn, soybean meal, soybean paste, palm, main anchovy, and palm kernel. First, the mixture is put into a storage tank, Mm.

The pulverized raw material is charged into an expander, expanded once at a temperature of 170 DEG C for 3 seconds at a pressure of 4 kg / m &lt; 2 &gt;, and then stored in another storage tank.

The expanded and stored raw materials were further mixed with 1.8 g of the limestone powder prepared above in an amount of 37.2 g of corn, 9 g of soybean meal, 7 g of seedling seed, 18 g of palm kernel, 9 g of main mooring and 18 g of palm kernel, . (See Table 1)

(Table 1) Content of raw feed of raw feed by using expander (g)

< Test Example  1> Palm leaves , Palm  Content comparison

The content of coconut and palm fronds of the fodder using the expander prepared in Example 1 and the general feed were compared.

(Table 2) Palm palm, palm content (%)

As shown in Table 2, the feed of the fodder using the expander undergoes an expansion process of each raw material, thereby changing the properties of the fiber at high temperature and high pressure to increase the digestibility. In the conventional feed, the cost of fodder is low However, by increasing the amount of low-priced raw materials such as palm and palm, which have not been used, in the present invention, it is possible to increase the digestibility and increase the amount of low-priced raw materials.

< Test Example  2> Comparison of mixing ratio

Table 3 shows comparisons of the degree of mixing of the feed with the other feeds with the feed of the extruder prepared in Example 1 and the general feed.

(Table 3) Mixing ratio comparison (%)

As shown in the above Table 3, the feed of the fodder using the expander is made in granule form and has a high mixing ratio. Thus, the mixing accuracy is excellent when mixed with other raw materials, and in the case of conventional feeds, However, since the granule of the present invention has a high mixing ratio, the pelletization process can be omitted and the production efficiency can be increased.

< Test Example  3> Search for preference

50 poultry were fed poultry feeds and general poultry feeds using the expander manufactured in Example 1 at the same time for 5 days.

(Table 4) Preference survey, feed exhaustion rate (%)

* July 13-20, 2014, Nonsan M Farm in Chungnam

As shown in Table 4, when the feed of the fodder using the expander was simultaneously fed with the general fodder, the feed exhaustion rate was higher than that of the general fodder. This has the effect of enhancing the meat quality of the palatable meat and improving the production efficiency by shortening the production period to slaughter.

< Test Example  4> Comparison of digestibility

The digestibility of the poultry feed using the expander prepared in Example 1 and the conventional compound feed were compared.

(Table 5) Comparison of digestibility (%)

* (Digestibility: Pepsin Digestibility)

As shown in Table 5, the feed of the fodder using the expander is significantly higher than the digestibility of the basic raw materials by modifying the properties of the fibrous material at high temperature and high pressure by increasing the digestibility of the raw materials through the expanding process of each raw material, The present invention has the effect of increasing the digestibility as well as improving the palatability and meat quality, as well as increasing the production efficiency by a simple process, because the digestibility of the compound feed which performs the extender twice is low until the pelletization process at low temperature and low pressure.
