Description

Method for preparing a mixed composition for adding piglets containing inorganic acid and silicate minerals, the mixed composition and feed {THE PRODUCT METHOD OF MIXING COMPOUND CONTAINING INORGANIC ACIDIFIER AND SCORIA, MIXING COMPOUND AND FEED}

The present invention relates to a piglet feed mixed composition prepared from an inorganic acid and a silicate mineral, and more particularly, a method of preparing a piglet feed mixed composition containing hydrochloric acid (HCl) and S Korea as a main component, prepared by the above method. The present invention relates to a mixed composition and a feed containing the mixed composition.

Recently, in pig farms in Korea, early reasons for reducing the breeding season of piglets from 5 to 6 weeks to 2 to 3 weeks have been carried out to increase the productivity of sows.

One of the problems caused by the early reasons of such piglets is that the amount of hydrochloric acid secreted from the weaning piglets is insufficient, so that the ability to digest solid feeds based on vegetable proteins and enzymes are reduced, and microbial flora in the small intestine is broken. Increased mortality due to diarrhea in piglets during digestive disorders.

In order to prevent death from piglet diarrhea, nutritionists have tried to improve the problems caused by adding dairy products to grain and vegetable-based feeds that improve the digestibility of premature lactating piglets. According to Graham (1981) and Cera (1988), the growth efficiency of piglets was improved when high-quality dairy products were added to weaned pigs. This is not only because lactose in dairy products has better bioavailability in the body than the complex carbohydrates in cereals, but it is also fermented by lactic acid by microorganisms in the stomach, which lowers pH in the stomach. Maner et al, 1962; Wilson and Wilson and Leibholz, 1981). However, it has been reported that the addition of dairy products to pig feed does not develop the digestive capacity of piglets and increases feed costs economically (Cranwell, 1976). From this point of view, acidification of weaned pig feed improves the growth of piglets by partially replacing dairy products and economically reducing feed costs.

In addition to adding dairy products to the above feeds, additives such as antibiotics and growth promoters have been used in feeds to solve the problems occurring in early lactating pigs. However, these additives are constrained because they can remain in the animal's body and cause potential harm to humans. Accordingly, organic acid was added to feed as an alternative to antibiotic use.

Additives that acidify feed are classified into organic and inorganic acids.

Examples of the organic acid include organic acids such as formic acid, acetic acid, propionic acid, butyric acid, lactic acid, citric acid, and fumaric acid. In addition to the acidification of the feed, the organic acids are used as a preservative, but the growth improvement effect of the piglets added with the organic acid is lower than that of the antibiotics and the growth promoter, and rather, it helps to absorb the antibiotics. There have been reports (Edmonds et al., 1985; Radecki, et al., 1988) In addition, the organic acid is added in small amounts when added to the feed at a high price, and when added for acidification of the feed by the addition of the organic acid Most hog farms have a big economic burden.

The inorganic acid is cheaper than the organic acid, while the feed industry or the farmer avoids because of the problem that the color of the feed changes black, there is almost no research on this.

In order to solve the above-mentioned problems, the present invention is mixed with hydrochloric acid (HCl) piglet feed to heat the mixture after mixing the volcanic mineral substance Sukori (main component is silicate), which is produced in large quantities in Jeju Island, Korea It is intended to provide a method of preparing the composition, a mixed composition produced by the above method and a feed containing the mixed composition.

The configuration of the present invention for solving the above technical problem is a method for preparing a pig feed mixed composition prepared by adding Sukkorea as a carrier to hydrochloric acid (HCl) and mixing the mixture to heat for 16 to 24 hours at 60 ℃ ~ 100 ℃ , A mixed composition produced by the above method and a feed containing the mixed composition.

In the present invention, the silicate material added to the feed to increase the productivity of the pigs includes zeolite, bentonite, kaolin, and also Jeju mountain volcanic ash powder (Scoria). The powder may increase the efficiency of the feed when the inorganic powder is added to the feed for the carrier action.

Accordingly, the inventors added a zeolite of 3% zeolite to the 40 weaning pigs for 4 weeks from July 2 to July 29, 2001 at the Seoul National University ranch, volcanic ash powder from Jeju. ) The effects of pig growth, nutrient digestibility, fecal excretion, and urine excretion were measured by comparing the control and control groups added with 3%. During the pre-test period (0 ~ 28 days), the daily weight gain was slightly different in 3% test and 3% zeolite ash powder according to the growth stage, but there was a significant increase in both test compared to the control. . In addition, protein digestibility of the volcanic ash powder of Jeju 3% test was better than the control and 3% zeolite added.

Therefore, the present inventors confirm that the feed added with sKORO than zeolite increases the growth of piglets from the above research data, and the present invention is to mix the sKORO as a carrier in inorganic acid (HCl) to prepare a mixed composition for piglet feed. In addition to the pig feed was shown the best embodiment of this test. However, it should be noted that the claims of the present invention are not limited to this embodiment.

Hereinafter, a method of preparing the mixed composition for piglet feed will be described in detail.

As shown in Table 1, when heated at 60 ° C. for 20 hours, the content of hydrochloric acid was 28.4% by weight, and the content of chloride ion was 27.98% by weight. The content of was reduced. In other words, feeding piglets is thought to reduce the amount released through the digestive system of the body.

The chloride ion content of the sKOREA and hydrochloric acid composite is preferably 25% to 30% by weight, more preferably 28% by weight. The optimal content of 28% by weight is that the content of chloride ions is less when the content of chloride ions is 25% by weight, the production effect of gastric acid (HCl) is insufficient, and when the content of chloride ions is 30% by weight, This is because there is a possibility of excessive secretion can damage the stomach wall.

Example 2

The mixed composition for piglet feed prepared by Test Example 2 was prepared according to the feed blending ratio of Table 2 below, and 40 weaned pigs were collected from Seoul National University ranch from August 17 to August 31, 2001. Weekly specification was made.

When the amount of chloride ions contained in the feed of Table 2 is 0.18% by weight, the content of chloride ions decreases, so that the production effect of gastric acid (HCl) is insufficient. Since there is a possibility of damaging the stomach wall, the content of the inorganic acid is most preferably 0.2% by weight.

The weight change, daily gain, daily feed intake, and feed efficiency of the 40 weaning pigs according to the mixing ratio of Table 2 were measured and shown in Table 3 below.

As shown in Table 3, the weight gain, daily gain, daily feed intake, and feed efficiency of the weaning pigs in the feed added with the inorganic acid prepared by the present invention increased with increasing the feeding period, in particular, the inorganic acid in the feed When the content was 0.2%, weight gain, daily gain, daily feed intake, and feed efficiency gradually increased with the feeding period. When the content of the inorganic acid is 0.05% by weight, the amount of chloride ions is reduced, so the production effect of gastric acid (HCl) is insufficient, and when the content of the inorganic acid is 0.25% by weight, the acid is excessively secreted by the excess chloride ion. Since there is a possibility of damaging the stomach wall, the content of the inorganic acid is most preferably 0.2% by weight.

The present invention prepared a mixed composition for piglet feed with an inorganic acid, but was concerned about the deterioration of taste and color, but by adding a silicate mineral, S Korea, as a carrier, to prevent dissolution of mucin in the intestine of the piglets, preventing the destruction of the barrier and improving the taste. The amount of feed intake was increased by preventing detection. In addition, the present invention is prone to growth delay due to diarrhea and decreased proteolysis due to the reduction of intestinal gastric acid in weaning pigs, but increased proteolysis by adding hydrochloric acid, which is a raw material of gastric acid, a protease, thereby increasing weight.

As described in detail above, the present invention provides a piglet feed additive by adding a silicate mineral as a carrier to the inorganic acid, thereby providing a chloride which is an intestinal gastric acid component that lacks weaning piglets, thereby increasing proteolysis and increasing growth.

In addition, the present invention has the effect of preventing the problem that the taste of the feed is lowered and the color is changed due to the strong acid when the inorganic acid is added directly to the feed by mixing the s Korea with the inorganic acid.

In addition, the present invention has an effect that can solve the economic difficulties of the Korean feed industry or pig farms by using an inorganic acid, which is cheaper than the organic acid commonly used in the feed industry as a raw material.
