Description

Feed and manufacturing method for maintaining homeostasis of piglets {omitted}

The present invention utilizes rice or its by-products to maintain proper homeostasis of newborn pigs (called "pigs" below pigs up to 40 days of age). The present invention relates to a feedstuff and a method of manufacturing the same. More specifically, the present invention can maintain homeostasis of piglets due to high content of short-chain glucose polymers and soluble peptides that are easily absorbed and used by piglets by hydrolyzing rice or by-products thereof under specific conditions. The present invention relates to a method for producing a piglet feed, and a piglet feed produced by the method.

It is well known that the initial growth rate of piglets is a very important factor in the growth and fattening of pigs, so that the success of pigs is dependent on the initial growth rate of piglets. By the way, the initial growth rate of piglets depends largely on maintaining homeostasis of piglets to maintain optimal condition, preventing diarrhea, and increasing feed intake and feed efficiency based on this.

Therefore, many people in this field have been continually researching to improve the survival rate and initial growth rate of piglets by identifying and satisfying the factors related to homeostasis that directly affect piglet's initial growth rate. It is true.

Meanwhile, the propagation of pigs, such as Gumi, has already raised pigs in preparation for the possibility that antibiotics accumulated in the pig body may be transferred to humans due to misuse and abuse of antibiotics to prevent diarrhea and disease prevention during pig growth and fattening. Researchers continue to develop feeds or feed additives to replace or reduce the use of antibiotics, as there are restrictions on misuse and abuse of antibiotics in the process, and furthermore, there is a trend toward regulating misuse and abuse of antibiotics worldwide. True efforts have been made.

Based on the known fact that diarrhea and the initial growth rate of piglets have a close relationship with the maintenance of homeostasis, the homeostasis of piglets is determined by the pH value of the circulatory system. , Blood pressure level, blood sugar level, electrolyte equilibrium, body temperature, and body fluid equilibrium, and piglets have less ability to maintain homeostasis by adapting to changes in the external environment than piglets, and factors related to homeostasis of piglets In order to maintain the normal state, the carbohydrates and sugars must be adequately supplied with basic energy requirements in response to changes in the external environment through carbohydrates and sugars. And if the assimilation of sugar is used properly, Catabolism begins and the body uses nitrogen and fat as energy sources to supply energy to the cells. As a result of catabolism, piglets can maintain their homeostasis due to the accumulation of metabolites such as lactic acid, phosphoric acid, uric acid and carbonic acid. It was recognized through various experiments that this would result in diarrhea and other detrimental effects, which in turn reduced the growth and survival rate of piglets.

Indeed, the representative external environmental factors affecting the homeostasis of piglets are stress before and after weaning. When we examine the structure of stress on homeostasis of piglets, when the piglets are stressed, it is the negative (energy) state of energy, that is, catabolism. The energy balance is generated, which leads to a decrease in immune function, insufficiency of major digestive organs, irregular respiratory system, irregular circulatory system, etc., resulting in poor homeostasis and ultimately low growth rate and survival rate.

Accordingly, the inventors of the present invention conducted a study on feed and feed additives that can maintain pig homeostasis, and feed and feed additives that can substitute for antibiotics, and short chains obtained by hydrolyzing rice or its by-products under specific conditions. Hydrolysates with high levels of glucose polymers and soluble peptides in the form are not only very easy to absorb and use by piglets, but also maintain homeostasis of piglets and prevent diarrhea that is lethal to piglet growth. The present invention has been completed.

Therefore, the present invention can maintain homeostasis of piglets by using rice or by-products of rice, and a method for preparing piglet feed for preventing diarrhea which has an absolute effect on the initial growth of piglets, The aim is to provide feed for piglets.

In order to achieve the above object, the present invention is a pre-heating step for the process of the rice or powdered by-products of the rice or by-products of the mill grinder in a hot water of 80 ℃ ~ 90 ℃. After soaking for 1 minute to 1 minute 30 seconds or steaming for about 45 seconds with steam, the water content is controlled to around 15% by hot water or steam with an extruder, and the temperature is 155 ℃ to 165 ℃, screw Extruded for 1 minute to 1 minute 10 seconds at a rotational speed of 150rpm, and then dried for 30 seconds to 45 seconds at a temperature of 120 ° C, and then pulverized with a grinder and repeated two times. It features.

Rice or a byproduct of rice, which is a raw material of the present invention, includes rice made by milling brown rice and degreasing steel remaining after squeezing oil from sargi, rice bran, and rice bran, which are by-products produced in the process, or a mixture thereof. do. Of course, it is more suitable as a raw material of the present invention because it is economically advantageous because rice which has been stored for a long time and is inadequate for edible food or saggi produced as a by-product and oil remaining after squeezing oil is economically advantageous than ordinary edible rice. would.

The grinding of raw rice or its by-products is more efficient because of the finer particles in the pretreatment and extrusion process with hot water or steam, the larger the surface area and the more efficient the reaction area. Although it is economically advantageous to be able to finish pretreatment and extrusion process in time.) However, excessive deterioration of starch or protein may occur due to excessive frictional heat in the grinding process, which may cause problems in the quality of the final product of the present invention. 200Mesh is appropriate in consideration of the presence and the pretreatment process using hot water or steam and the extrusion process using hot water under specific conditions. As a type of grinder, single disk rotating only one of the opposing disks generally used for grinding of grains or double disk disc attrition mills rotating both opposing disks was most advantageous for achieving the object of the present invention. .

The preconditionjng by hot water or steam is an extruder process that can achieve the object of the present invention by rapidly raising the temperature of raw materials to gelatinazation temperature and denaturation temperature for protein decomposition and making the dispersion of water uniform. Preheating is a process that preheats to make it smooth. Excessive temperature exceeding the prescribed temperature or time (immersion for 1 minute to 1 minute and 30 seconds in hot water of 80 ℃ ~ 90 ℃ or steamed for 45 seconds with steam) Preheating by temperature or time should be avoided. If the pretreatment process can achieve the same effect, it is convenient to treat with steam for the efficiency of the work, and it is advantageous for the efficiency of the work to be installed in connection with the device for extrusion.

The process of exposing the pretreated raw material by steam or hot water is a device that can be supplied with hot water or steam so that moisture can be maintained at about 15% by hot water or steam. If the extruder can be satisfied, there is no problem. Extrusion condition of the present invention is that the starch particles are not destroyed, but the structure of the starch is partially cleaved to increase the short-chain glucose polymer which can be easily used as an anabolic substance in a short time, and effective solubility. Peptide content is high, so that it can be melted well in cold water to obtain highly adaptable hydrolyzate as feed. Extrusion should be performed within 160 minutes at 160 ℃ under 15% moisture. If it is lower, the structure of the starch particles is not cut to a satisfactory level, so that the content of the short-chain glucose polymer or the soluble peptide is low, the solubility in cold water is poor, and the adaptability to the feed is low, and the temperature is excessively higher. Higher or longer time results in excessive heat denaturation of the starch particles. This very issue falls will occur. Of course, the screw speed and other related factors in the extruder are set based on the treatment for 1 minute at 160 ° C., but the difference in screw speed greatly affects the result, so it should be maintained at about 150 rpm.

The drying process may be carried out in a conventional dryer so that the final moisture content is 4% or less, and a continuous dryer connected to the extruder may be used to perform continuous work with the extruder. After drying, it is transferred to the grinder and grinds. If it is a disc attrition mills used to grind rice, there is no problem, and the adaptability of the blending process (uniform distribution in the blended feed) and piglets when blending with other feeds 150Mesh is appropriate when considering the characteristics of eating habits, and the uniformity of particles also affects the adaptability of the mixing process and the feeding of piglets. It is advantageous to increase the uniformity of the particles by grinding the particles again in the same way.

Hereinafter, the present invention will be described in detail with reference to Examples and Comparative Examples, but the scope of the present invention is not limited thereto.

<Example 1>

100 kg of rice is put into disc attrition mills and pulverized with 200Mesh, and the pulverized product is preheated by spraying steam for about 45 seconds into a preheater connected to the extruder, and the moisture content in the extruder While maintaining water at about 15%, extrude at 160 ° C for 1 minute while supplying water by hot water or steam, and then transfer to a rotary dryer and dry for 35 seconds at 120 ° C to obtain 4% moisture. It was made to be the following. The dried material was decomposed to 150Mesh particle size with a disc friction mill and then separated by a shaking sifter twice to obtain a feed capable of maintaining 93 kg homeostasis.

<Example 2>

Instead of rice was used as a by-product of rice, except for the same process as in Example 1.

When the digestibility of the feed for piglets consisting of the hydrolyzate of rice of the present invention obtained in Examples 1 and 2 was treated by other methods, the digestibility by piglets (pancreatin enzyme) of rice processed was compared. Digestibility of feed produced by the method was about 20-50% higher than those treated by other methods.

Table 1. Digestibility by Pancreatin Enzyme

Table 2. Comparison of Growth Rates of Piglets

Test Method: The test pigs and the control pigs were 100 heads of piglets, and the pigs were fed from 6 days of age to 2 weeks after weaning (35 days of age) to compare weight gain. The test group was fed the piglet feed of the present invention prepared by the method of Example 1, the control group was fed a commercial piglet feed commercially available in the market and both groups did not receive a separate antibiotic.

In Table 2, the test group fed the piglet feed of the present invention showed a 20% higher gain rate than the control group, and the number of diarrhea piglets was significantly reduced. On the other hand, in the survival test of other piglets, the survival rate of the group fed the feed of the present invention was about 5% higher than that of the normal pig feed.

The mechanism of the effect of piglets in the present invention on the body of piglets is to maintain the osmotic pressure in the body and to reduce the incidence of acidosis by maintaining the alkalinity of the body fluid by reducing the release of sodium ions from the small intestine of the intestinal mucosa. On the other hand, by promoting the absorption of glucose to maintain the optimal blood sugar level to minimize the feed rate and absorption insufficiency, and to improve the history of history to maintain the body's homeostasis. The increase in growth rate and survival rate is attributable to the increase in growth retention phenomenon, diarrhea and disease resistance due to the stabilization of factors related to homeostasis by this mechanism.

Piglet feed of the present invention can be fed by replacing the normal feed for piglets from 1 week old to 6 weeks of age, it is also possible to use a mixture with a common feed for piglets.

Piglet feed prepared by the manufacturing method of the present invention continuously maintains the factors related to homeostasis of piglets, such as the pH value of the circulatory system, the blood sugar level of the body, the balance of electrolyte, the balance of body fluid and blood pressure, etc. It has the effect of sustaining homeostasis. By maintaining the homeostasis of piglets, it is excellent to increase the survival rate and weight gain by increasing resistance to growth stagnation and disease caused by diarrhea, stress before and after weaning, etc. By improving the intestinal environment, it prevents diarrhea and directly improves resistance to other diseases, reducing the dose of antibiotics that are being overdosed to prevent diarrhea in piglets and diseases associated with growth stagnation during weaning. The effect is also excellent.
