Abstract

PROBLEM TO BE SOLVED: To solve conventional problems that cattle excretes a large amount of the feed rice used as cattle feed without sufficient absorption when it is applied to the cattle in an original condition, whereas, when the feed rice is made into powder, a large amount of the feed rice is absorbed in the stomach and then the cattle is driven into fully fed condition intermediately, resulting in fault in supplying the cattle with a sufficient amount of feed.SOLUTION: The feed rice used as a cattle feed of the invention is prepared by roasting rice with chaff, grinding it and making it into powder. That is, by roasting the rice with chaff, the rice with chaff is puffed and softened appropriately. The puffed rice with chaff is ground into appropriate powder in which all rice has not been made into powder. Thereby, it is realized to suppress absorption by digestion in the cattle's stomach, to promote absorption by digestion in his intestines, prevent the cattle from being driven into fully fed condition intermediately, and supply the cattle with a sufficient amount of feed. In addition, by using the rice with chaff, it is provided an excellent feed rice in nutrition balance.

Description

  The present invention relates to a feed to be fed to cattle, and particularly to a feed rice used for cattle feed.

  In recent years, there is a feed using rice as a feed to be fed to livestock such as cattle. This uses rice for the purpose of improving the domestic feed self-sufficiency, which is sluggish, and such rice is sometimes referred to as feed rice, as distinguished from edible rice. This kind of feed rice is used as it is by mixing it with a conventional concentrated feed made of corn or the like, or by removing the rice cake. In addition, there is a feed for livestock that uses rice that has been pulverized and pulverized, for example (see Patent Document 1, for example).

  On the other hand, as human edible processed products, there are edible powders obtained by washing high-pressure rice cakes, then heating the rice cakes under hot air for a predetermined time, and then pulverizing the hot-dried and roasted rice cakes to form a powder (for example, , See Patent Document 2).

  By the way, cattle digest food in the stomach and intestines. However, when feed rice with raw rice or rice husks removed is fed to cows, the amount of food that is excreted without being digested in the stomach or intestine is increased because the feed rice is hard, and it is not fully digested and absorbed. . That is, such a feed has a problem that the meat quality and milk quality of the cow deteriorate.

  In addition, when the edible powder in the form of powdered glutinous rice described in Patent Document 2 is fed to a cow as a feed, the powder adheres to the intestinal fine hairs to generate gas, or it is immediately digested and absorbed in the stomach. The cows don't eat enough of the feed, such as the blood sugar level of the dog rising and becoming full soon. That is, in this case as well, there was a problem that the meat quality and milk quality of the cow deteriorated.

  The present invention suppresses absorption in the stomach and absorbs it in the intestine, so that the cow can be fed with the desired amount of feed, has excellent nutritional balance, and improves the meat quality and milk quality of the cow. It aims at providing the manufacturing method, the feed for cattle containing feed rice, and the fattening method of the cow using the feed for cattle.

  The feed rice according to the present invention is feed rice used for cattle feed, and is characterized by roasting and crushing rice with rice husk into granules.

  According to this structure, rice with a rice husk is roasted so that the rice with a rice husk expands and softens moderately when the internal moisture evaporates. In addition, by crushing the roasted rice with rice husks into granules, they are not digested and absorbed immediately in the stomach as if everything were powdered, and digested and absorbed in the intestines while suppressing digestive absorption in the stomach. Can be absorbed. Therefore, the cow is not immediately full, and the cow can be fed with the desired amount of feed. As a result, the meat quality and milk quality of the cow can be improved. Furthermore, by using rice with rice husks without using rice without rice bran, the nutritional balance is good, and the meat quality and milk quality of the cow can be improved.

  Preferably, the roasting is performed until the surface temperature of the rice with husk is 90 ° C to 150 ° C. If roasting is stopped in a state where the surface temperature of the rice husk with rice is lower than 90 ° C., the rice with rice husk may not be expanded and may be hard. In addition, when roasted to a temperature higher than 150 ° C., the rice husk with rice husk becomes too soft and soft (becomes like a pon confectionery), and when crushed, it may not be granular and many may be powdered. . In addition, the surface temperature of the rice husk with rice is measured by, for example, a non-contact thermometer such as an infrared radiation thermometer.

  Preferably, the roasting is performed until the surface temperature of the rice husk with rice husk reaches 100 ° C to 130 ° C. By roasting the surface temperature of the rice with rice husk to 100 ° C. to 130 ° C., the rice with rice husk has good swelling and firmness and is well balanced as feed rice used for cattle feed.

  Preferably, the grain size of feed rice is 4.0 mm or less. Thereby, a cow can digest and absorb feed rice moderately. More preferably, the particle diameter of feed rice is 3.0 mm or less. In addition, in order to make the particle size of feed rice 4.0 mm or less, 3.0 mm or less, or 2.0 mm or less, for example, the rice with rice husk roasted using a roll mill or the like is crushed, and then a shifter or the like is used. Used to obtain feed rice with a predetermined particle size. In this way, most of the feed rice obtained by crushing rice with rice husks by setting such as a roll mill or a shifter has a particle diameter of 1.0 mm to 4.0 mm or 0.5 mm to 3.0 mm. it can.

  The feed for cattle which concerns on this invention is characterized by including the feed rice of any one of Claims 1-5. Moreover, it is good also as cattle feed containing 1%-60% of the said feed rice. Cattle feed includes conventional concentrated feeds mainly made of corn and the like. For example, feed rice can be added instead of part of corn. Moreover, it is good also as using 100% of feed rice as a feed for cattle instead of all the concentrated feeds which use corn etc. as a main raw material. Since the feed rice of the present invention uses rice with rice husk, it contains rice husk containing essential amino acids in addition to rice mainly containing carbohydrates, and this feed rice alone has a good nutritional balance.

  The fattening method for cattle according to the present invention is characterized in that the cattle feed according to claim 6 or 7 is fed to the cattle. According to this configuration, by supplying the feed for cattle containing the feed rice having an excellent nutritional balance, it is possible to improve meat quality and milk quality.

  The method for producing feed rice according to the present invention includes a first step of roasting rice with rice husk until the surface temperature of the rice with rice husk reaches 90 ° C. to 150 ° C., and crushing the rice with rice husk into granules And a second step, wherein the grain size of the rice with rice husk is adjusted to 4.0 mm or less by the second step.

  Preferably, the first step is a step of roasting until the surface temperature of the rice with husk reaches 100 ° C. to 130 ° C., and the particle size of the rice with husk by the second step is 3. 0 mm or less.

  Further, the method further comprises a third step of sieving the rice with rice husk that has been crushed and granulated, and the rice with rice husk has a predetermined size such as a particle size of 4.0 mm or less or 3.0 mm or less. Until it becomes, you may repeat said 2nd process and said 3rd process.

  As described above, according to the feed rice of the present invention, when the feed rice is fed to cattle with a moderately hard granular shape, digestion and absorption in the stomach can be suppressed, and the desired amount can be fed, and digested sufficiently. Absorb. In addition, this feed rice has excellent nutritional balance because it is made from rice with rice husks. By feeding cattle feed containing this feed rice to cattle, meat quality and milk quality can be improved. .

<3. Manufacturing process>
Next, the manufacturing process of the feed rice 1 of this embodiment is demonstrated based on drawing.
(Step S1)
As shown in FIG. 3, in order to manufacture the feed rice 1, the rice 10 with chaff is introduced from below the first elevator 20a.

(Step S2)
The rice with rice husk 10 put into the first elevator 20a is carried upward by the first elevator 20a and supplied to the fixed quantity feeder 21. Subsequently, a predetermined amount (about 50 kg in the present embodiment) of rice husk 10 is supplied to the roasting machine 22 from the quantitative feeder 21.

(Step S3)
And the rice 10 with chaff is roasted by the roasting machine 22. In the present embodiment, for example, the rice husk 10 is roasted until the surface temperature of the rice husk 10 reaches about 110 ° C. In this case, the rice husk 10 is roasted by the roasting machine 22 for about 3 to 4 minutes. At this time, the amount of water contained in the rice husk 10 is reduced from about 14-18% to about 5-8%, and at the same time, the rice husk 10 is expanded and softened appropriately. Moreover, the alpha conversion degree of the expanded rice with rice husk 10 is about 30% to 50% (in this embodiment, 42.8% (see FIG. 4)). With such a degree of alpha, when the rice husk 10 is crushed, all the rice husk 10 is not powdered, and the particle diameter is 2.0 mm, 3.0 mm, 4.0 mm, etc. It can be a granular shape of a predetermined size.

  On the other hand, when roasting rice husk 10, if the surface temperature of rice husk 10 is too high, such as 160 ° C. or higher, most of the water contained in rice husk 10 is reduced. On the contrary, it becomes too hard or the swelling becomes too large. That is, it becomes a state like popcorn in corn. In this case, when the roasted rice husk 10 is crushed, the rice husk 10 becomes too small and becomes powdery.

  In addition, in this embodiment, the surface temperature of the rice 10 with chaff at the time of roasting is measured non-contactingly with an infrared radiation thermometer as an example.

(Step S4)
The rice 10 with rice husk roasted by the roasting machine 22 is then transported to a sorting machine 23, and the rice 10 with rice husk is passed through a 7 mm net and a 3 mm net by the sorting machine 23. (Remaining on the net) and carbonized whiskers (falling under the 3 mm net) are screened and removed to obtain carefully selected rice 10 with chaff (remaining between the 7 mm net and the 3 mm net).

(Step S5)
The carefully selected rice 10 with rice husks is put below the second elevator 20b, conveyed upward by the second elevator 20b, and then stored in the silo 24. Here, the rice with husk 10 heated by the process of step S4 and having heat is self-roasted using the self-heat, and at the same time is naturally cooled. In the present embodiment, the roasted rice husk 10 is stored in the silo 24 for about 4 to 5 hours, and self-roasting and natural cooling are performed.

(Step S6)
Next, the rice 10 with rice husk is conveyed from the silo 24 to the stone removing machine 25, and the stone removing machine 25 removes pebbles, gravel and the like mixed in the rice 10 with rice husk. Specifically, air (wind) is applied to the rice husk 10 with rice husk to separate the pebbles, gravel, etc. having a relatively high specific gravity from the rice 10 with rice husk, thereby removing the pebbles, gravel, etc. At the same time, the rice husk 10 is cooled by air (wind).

(Step S7)
Then, the rice husk-attached rice 10 passes through a stone punching machine 25 and is conveyed to the first crushing machine 26a disposed below the rice hulling machine 25 to be crushed. In this embodiment, for example, rice husk-attached rice 10 is set to be crushed to 3.0 mm. In addition, it is difficult to accurately set the particle diameter of all rice husks 10 to 3.0 mm because of crushing rice with rice husks, and some of them are naturally larger or smaller than 3.0 mm. .

(Step S8)
Next, the crushed rice 10 with chaff is carried to the first shifter 27a. In the present embodiment, the first shifter 27a uses a sieve mesh of 3.0 mm mesh, so that the rice husk rice 10 having a particle size larger than 3.0 mm remains on the sieve mesh. Those below 0.0 mm fall off the sieve mesh and are separated. In addition, rice with a rice husk 10 having a particle size larger than 3.0 mm proceeds to step S9, and rice with rice husk 10 having a particle diameter of 3.0 mmmm or less proceeds to step S10.

(Step S9)
Rice husk 10 with a particle diameter larger than 3.0 mm remaining in the first shifter 27a is conveyed to the second crusher 26b and crushed again.

(Step S10)
In step S8, the rice husk 10 having a particle size of 3.0 mm or less and the rice husk 10 crushed again by the second crusher 26b in step S9 are both carried to the pneumatic transport device 28.

(Step S11)
The rice 10 with rice husk supplied to the pneumatic transporter 28 is transported from below to above in the pneumatic transporter 28 and supplied to the product tank 29. At this time, roasted and crushed rice with rice husk 10 is almost completed as feed rice 1, and the following steps S12 to S14 are like a check process before product shipment.

(Step S12)
The rice 10 with rice husk supplied to the product tank 29 is conveyed to the second shifter 27b. In the present embodiment, the second shifter 27b uses a mesh screen of 3.0 mm mesh, like the first shifter 27a, and therefore the particle diameter of the rice husk 10 is larger than 3.0 mm. Things remain on the screen, and those below 3.0 mm fall off the screen and are separated. Further, rice husk rice 10 having a particle size larger than 3.0 mm proceeds to step S13, and rice husk 10 having a particle size of 3.0 mm or less proceeds to step S14 as feed rice 1 for product shipment.

(Step S13)
The rice 10 with rice husks having a particle diameter larger than 3.0 mm remaining in the second shifter 27b is transported to the third crusher 26c, further crushed, and transported to the pneumatic transport device 28 (return to step S10). .

(Step S14)
On the other hand, rice husk 10 with a particle size of 3.0 mm or less in step S12 becomes feed rice 1 for product shipment. Rice husk rice 10 which is a raw material is generated as feed rice 1 by the above steps S1 to S14. In addition, in step S12 of this embodiment, since rice with a rice husk 10 with a particle diameter larger than 3.0 mm remaining on the second shifter 27b is very small, the feed rice 1 is obtained through the steps S1 to S11. It is good also as completion.

<4. Cattle feed>
Next, the cattle feed 101 using the feed rice 1 will be described. The cattle feed 101 of this embodiment is a cattle feed intended to be used mainly for beef cattle. The feed for cattle 101 is prepared by mixing the feed rice 1 with a conventional thick feed mainly made of corn so that the feed rice 1 is about 30% of the whole cattle feed 101. And the feed 101 for cattle with the excellent nutritional balance produced in this way is fed to beef cattle to fatten the beef cattle.

  FIG. 5 is a rating specification for beef cattle that were fattened by experimentally feeding cattle feed 101. As shown in FIG. 5, the beef cattle fed the cattle feed 101 was able to obtain a rank of A5 rank. Thus, it is thought that the ratio which becomes a cow of A5 rank improves by feeding the cattle feed 101 of this embodiment to a cow. In addition, although the feed 101 for cattle of this embodiment mixed the feed rice 1 in the ratio of about 30%, it is not restricted to this, It is good also as mixing in other ratios and making the feed rice 1 100%. Moreover, although the example which uses the cow feed 101 for beef cattle was described in this embodiment, it is not restricted to this, It can also use for a dairy cow and milk quality will improve if it uses for a dairy cow.

<5. Effects of this embodiment>
As explained above, according to the feed rice of this embodiment, the rice with rice husk can be roasted and expanded to be moderately soft. Moreover, by pulverizing the expanded rice with rice husks, it can be made into granules of an appropriate size. This suppresses the generation of gas due to powder adhering to the intestinal fine hair, as in the case where everything is powdered, and it is not digested and absorbed immediately in the stomach, so the amount of digestion and absorption in the stomach Can be suppressed and digested and absorbed in the intestine. Therefore, it is possible to prevent the cow from becoming full immediately and feed the cow with a desired amount of feed. Moreover, the meat quality and milk quality of a cow can be improved by feeding the cattle feed mixed with feed rice and fattening the cow. In addition, by using rice with rice husk as the raw material of feed rice, compared to the case of using rice without rice bran, it can be a feed rice with a better nutritional balance, which also improves the meat quality and milk quality of cattle. Improvements can be made.

  On the other hand, in the case of feed rice from which rice husks have been removed, disposal of the removed rice husks is necessary, but by using rice with rice husks as feed rice, it is not necessary to dispose of rice husks, and the labor and cost can be reduced. In addition, since the ratio of imported food such as corn is extremely high in conventional feed, feed self-sufficiency can be improved by using feed rice, and fallow fields can also be used.

<6. Other Embodiments>
As described above, the preferred embodiments of the present invention have been described with reference to the drawings, but various additions, modifications, or deletions can be made without departing from the spirit of the present invention. In particular, in this embodiment, the feed rice having a particle size of 3.0 mm or less is used, but the particle size of the feed rice is not limited thereto, for example, 4.0 mm or less, 2.0 mm or less, or 1.0 mm to It is good also as 3.0 mm, 0.5 mm-2.5 mm, etc. In addition, the particle diameter of feed rice can be varied depending on the setting of the crusher and shifter, for example. In the present embodiment, roasting is performed until the surface temperature of the rice with rice husk reaches about 110 ° C. However, the present invention is not limited to this. For example, the surface temperature of rice with rice husk is 90 ° C to 150 ° C. Alternatively, roasting may be performed until a predetermined temperature of 100 ° C to 130 ° C, 115 ° C, 120 ° C, 125 ° C, 128 ° C, or the like is reached. Moreover, in this embodiment, about 30% of feed rice is mixed with the total amount of feed for cattle, but may be 10%, 60%, or 100%, for example. Therefore, such a thing is also included in the scope of the present invention.

  In addition, the feed rice and cattle feed of the present invention are superior in nutritional balance as compared to conventional feeds, and therefore can be used for livestock such as goats and sheep other than cattle.
