Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to feed additives for livestock such as pigs and cows, or feed additives that are used to feed feed, and in particular, to improve the digestion and absorption of feed. The present invention also relates to a feed additive that can reduce the odor of excreted excrement.

(Prior art) Conventionally, feed for livestock such as cows and pigs, and chickens, etc., has been fed with high nutritional value and high protein II thick feed by ad libitum feeding method for the purpose of improving meat production efficiency. Thereby, methods are being used to shorten the breeding period.

However, in modern livestock sheds, feeding facilities and excrement disposal are mechanized and labor-saving, just like in general factories. , they require the same feed as in grazing conditions, and also require plenty of rest.

However, when raising and fattening livestock, the livestock are crammed into a small space and fed with the above-mentioned feed without being allowed to exercise.
Internal organs do not function properly, which often results in the ingested food not being fully digested. Therefore, undigested feces and the like are excreted, and the odor of the excrement is a cause of livestock pollution, and the disposal of such excrement is a major problem for livestock farmers.

In addition, continuing to feed concentrated feeds like those mentioned above is important for livestock! It also has a major impact on health, and raising unhealthy livestock has a negative impact on the quality of meat produced from them.

On the other hand, efforts have been made to prevent the outbreak of disease by mixing antibiotics into the feed, which has made it possible to raise large numbers of rJA in small spaces.
This causes other problems, such as antibiotics administered to livestock remaining in the meat.

In addition, to solve the problem of indigestion caused by lack of exercise or excessive feeding of concentrated feed in livestock, for example, as shown in Japanese Patent Application Laid-open No. 198-190358, zeolite It has been proposed to mix molasses into powder and feed it alone to livestock or mix it into silage.

The zeolite is said to be able to adsorb ammonia gas generated in the stomach and intestines, thereby preventing indigestion, bad odor of excrement, etc.

Separately, as shown in Japanese Unexamined Patent Publication No. 52-47484, feed additives can be produced by culturing microorganisms that produce a large number of digestive enzymes using waste fluid from food factories and adsorbing them to zeolite. A method has been proposed to obtain the .

The feed additive obtained by this method is said to be effective in improving the digestion of livestock and reducing the odor of manure due to the synergistic effect of digestive enzymes and zeolite.

(Problems to be Solved by the Invention) However, the conventional feed additives described above merely utilize the gas adsorption effect of zeolite.
By adsorbing gases such as ammonia gas in the gastrointestinal tract, only the adverse effects caused by those gases can be prevented.

In addition, when the additive contains microorganisms for digesting and absorbing feed, and the products of these microorganisms, although a synergistic effect can be expected from the digestive enzymes and zeolite, etc., the addition of It has the disadvantage that it causes problems with the storage stability of the product, and its use is limited to breeding farms and the like that are established adjacent to areas where microorganisms and the like are produced.

(Objective of the invention) The present invention solves the drawbacks of conventionally used feed additives as described above, and improves preservability and usability by suppressing the activity of effective microorganisms in dry conditions. In addition to providing a feed additive that can be used as a nutritional source by itself, the present invention also aims to provide a feed additive that can reduce the feed conversion rate of livestock and reduce the odor of excreted manure. is intended to provide.

(Means and effects for solving the problem) The livestock fAFl additive of the present invention is produced by mixing vermiculite with a calcium component, and adding to the mixture a base agent for effective microbial breeding, such as natto fungus, yeast, and red koji. It is manufactured by mixing effective microorganisms such as bacteria that have been propagated.

Also, an effective microbial cell propagation compound that is mixed into the livestock feed additive of the present invention! ! Mixtures of rice bran, fishmeal, seaweed powder, amino acids, nucleic acids, etc. can be used as the additive, and these mixtures can be used to improve the quality of livestock feed additives when water is added to the livestock feed additives. This allows microorganisms to grow in the environment.

Furthermore, the calcium component to be mixed into the livestock feed additive of the present invention is rich in calcium components such as shellfish fossils and coral powder, and even when produced as a fine powder, there are minute voids inside. This method uses materials that have good adsorption and preservation properties for microorganisms or their products.

When the livestock feed additive of the present invention is given to livestock, it is possible to add 2 to 4% of the weight of melon in the feed, thereby increasing the protein content in the mixed feed.
It becomes possible to maintain good digestion and absorption of fibers and the like.

Therefore, by adding the livestock feed additive of the present invention to feed, it is possible to prevent the occurrence of indigestion and self-poisoning caused by harmful bacteria, improve the initial growth efficiency of livestock, and improve digestive efficiency. Therefore, the feed conversion rate can be reduced.

Furthermore, the livestock feed additive of the present invention contains a calcium component, an effective microbial cell breeding base agent, etc.
Along with products produced by microorganisms, it becomes a nutritional component for livestock, improving its nutritional effects, as well as having the effect of adsorbing gas in the gastrointestinal tract due to vermiculite, and the crystals of vermiculite stimulating the inner wall of the digestive tract and activating the functions of internal organs. It becomes possible to obtain.

In addition, in the livestock feed additive of the present invention, in addition to a part of the effective microorganisms contained therein acting as an intestinal regulator, other microorganisms also promote the digestion and absorption of feed within the livestock body. , high protein feed, etc. can be digested in good condition and absorbed as nutrients, so the efficiency of digestion and absorption of feed eaten by livestock is improved.

In addition, by improving the efficiency of digestion and absorption of the feed ingested by livestock, the amount of undigested components in excreted manure is reduced, reducing its odor, and the microorganisms contained in the excrement even after excretion. Since the proliferation of harmful microorganisms is suppressed, the generation of bad odors can be reduced, thereby improving the sanitary conditions of livestock barns.
