Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed additive composition having an excellent effect of improving the growth of piglets or chickens, and a mixed feed containing the composition.

[0002]

2. Description of the Related Art Improving the growth of chicks and piglets in the poultry and pig farming industry is directly related to the management of the chicks and piglets, which may lead to death due to the occurrence of diseases and developmental defects, or to a decline in commercial value. Is extremely important. As a means for improving the growth of such chicks and piglets, a method of adding antibacterial substances (antibiotics and synthetic antibacterial agents) to the feed is widely adopted.

The mechanism of action of the growth-improving effect of this antibacterial substance is said to be the influence on the intestinal bacterial flora and the improvement of the nutrient absorption rate due to the action on the intestinal tract, but there are still many unclear points. However, the addition of this antibacterial substance to feed has problems such as public health problems due to the emergence of resistant bacteria and problems of residual antibacterial substances in meat. Therefore, when an antibacterial substance is used, conditions such as being an antibacterial agent exclusively for animals distinguished from a drug for human body, being non-absorbable and not remaining in meat are required.

Further, citric acid, tartaric acid, fumaric acid, malic acid, formic acid, lactic acid, etc. are added for the purpose of imparting sourness to the feed (Masayuki Okamoto, "FEEDING" Chikusan Publishing Co., Vol. 31, Vol. 31, No. 9). No., pp. 143-145, 199.
1 year). However, the feed containing these acids has no problem in terms of safety, but has a low growth-improving effect and is not practical.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a feed additive composition for piglets or chickens which is highly safe and has a high growth-improving effect.

[0006]

Therefore, the present inventors have
As a result of testing many substances among the highly safe substances to find a component excellent in the growth-improving effect of piglets, etc., when L-glutamic acid and citric acid were added to the feed in combination, the result was that of piglets and chickens. The present invention has been completed by finding that the growth can be remarkably improved.

That is, the present invention provides a feed additive composition for piglet or chicken chicks, which contains L-glutamic acid and citric acid, and a compounded feed containing the composition.

In the present invention, the mixing ratio of L-glutamic acid and citric acid is preferably 20:80 to 80:20 by weight.

The feed additive composition of the present invention may be a mixture of the above-mentioned two essential components, but it is preferable from the viewpoint of utilization that the composition is adsorbed or increased with an adsorbing substance or a shaping substance, diluted, and formulated. . In addition, the feed additive composition of the present invention may be mixed with other nutritional components such as amino acids, vitamins and minerals. When formulated in this way, the total content of essential components is 0.1% by weight (hereinafter, simply “%”).
The above is preferable. In formulating, essential components, excipients, adsorbents, nutritional components, etc. may be mixed according to a conventional method. The excipient is not particularly limited, powdered silicic acid, silicic acid anhydride, light silicic acid anhydride,
Hydrous silicon dioxide, diatomaceous earth, zeolite, activated clay, colloidal silica, saccharides and the like are preferable. The adsorbing substance is not particularly limited, but powdered silicic acid, diatomaceous earth, zeolite, colloidal silica and the like are preferable.
The amount of the above composition added to the compounded feed is 0.025 to 0.25% in total as an essential component, preferably 0.0
The range of 5 to 0.2% is preferable. This amount is 0.025%
If it is less than the above range, the growth is not improved, and even if it exceeds 0.25%, no further effect can be expected, which is not preferable.

L-glutamic acid and citric acid are
It may be added directly to the compounded feed. Here, the mixed feed to which the composition of the present invention can be added is not limited as long as it is used for raising piglets or raising chicken chicks.

[0011]

EFFECT OF THE INVENTION The feed additive composition of the present invention contains L-glutamic acid and citric acid to increase the weight gain of piglets and chickens, while at the same time improving the feed utilization rate and feed intake. Improving and improving productivity. Furthermore, it prevents loose stools and diarrhea of piglets and chickens, helps maintain health, and improves uniform growth of the herd.

[0012]

The present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

EXAMPLE 1 After hatching, 8 days old male and female chicks with an average weight of 53 g were placed in each group 2
The number of chicks was set to 0 and a chick breeding test was conducted for 6 days. The test feed was a basic feed containing no antibacterial substances and having a metabolic energy of 2.74 kcal / g (compound content,%: soybean oil 10.00, cellulose 17.92, corn starch 15.50, soybean meal 51.

A mixture obtained by directly adding and mixing the acid shown in Table 1 to 0) was used. The compounded feed was fed ad libitum and the water was freely drinkable. Table 1 shows the test results for each category. The "rate" of the average weight gain and the average feed intake in the table is shown as a relative value when Category 1 is 100. The average feed conversion rate is a value obtained by dividing the average feed intake by the average weight gain.

[0014]

[Table 1]

As shown in Table 1, the results of the combined use group of L-glutamic acid and citric acid were very good, and the non-addition group and the single-use group of the test substance showed poor results. Moreover, in the combined use group of L-glutamic acid and citric acid, the results were better when the ratio of L-glutamic acid and citric acid was equal to or close to that. In the observation of feces during the test period, some soft stools were observed in the non-addition group and the single-use group, but there was no abnormality in the combined group. The growth rate was 100% in each ward.

Example 2 Ten-day-old weaned piglets, 22 days old and having an average body weight of 6.4 kg, were used in each group for a 2-week breeding test. The test feed is an artificial milk premixed feed containing no antibacterial substances (mixing content,
