Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for producing drinking water for livestock, and in particular, a novel drinking water for livestock that can prevent odor of dung of livestock such as chicken and pig. Manufacturing equipment

[Conventional technology]

For poultry and pig farming, there are permanent issues such as measures to prevent odor of livestock dung, disease outbreaks and flies outbreaks.

Looking at the conventional measures against odors and the prevention of flies, it is common to clean feces and use deodorants or insecticides (for example, JP-A-52-16487, JP-A-62-297288, and JP-A-63-287288). 203161
In addition, antibiotics are used in large quantities for the prevention of disease outbreaks.

[Problems to be Solved by the Invention]

However, even if any of the conventional odor prevention measures and flies generation prevention measures are adopted, it is not possible to effectively prevent the generation of odors and flies, and the local residents around the poultry farms and pig farms still find themselves The reality is that we are receiving complaints. Further, when a large amount of antibiotics is used, not only the cost becomes high, but also the disease resistance increases, and it becomes necessary to use stronger antibiotics.

Under such circumstances, the present inventor provides a technology capable of effectively preventing the generation of odors and flies in chicken farms and pig farms, and preventing the occurrence of diseases without using a large amount of antibiotics and the like. Therefore, as a result of extensive studies, it was found that the above technology could be established by improving drinking water for livestock, or a specific apparatus for producing drinking water for livestock has not been developed and its development is desired. It was

Therefore, the present invention is a novel drinking water production for livestock that can effectively prevent the generation of odors and flies in poultry farms and pig farms, and can prevent the occurrence of diseases without using large amounts of antibiotics and the like. The purpose is to provide a device.

[Means for Solving the Problems]

The livestock drinking water producing apparatus according to the present invention is a drinking water tank or the like having a supply part and a discharge part of tap water, etc., and a group of bacteria in which soil anaerobic bacteria or aerobic bacteria and soil anaerobic bacteria coexist. A reactor filled with a substance that induces a phenol metabolite due to the activity of, and a substance containing a large amount of activated silicic acid content is arranged in or near the reactor, and It is characterized in that an air supply unit is provided below.

Further, the livestock drinking water production apparatus according to the present invention has a livestock drinking water tank, and a circulation circuit that sucks up the water in the water tank with a circulation pump and returns it to the water tank again, and a phenol metabolism inducer is included in the circulation circuit. It is characterized in that a filled reactor and an air supply unit are provided.

In the present invention, the substance that induces a phenol metabolite is preferably a humus precursor of a phenol compound contained in any of humic plants, lignite, peat, grass peat and the like. Here, the humus may be either a humus mixed with a humus precursor or a humus mixed with a humus.

The livestock to which the present invention is applied may be birds and animals fed to humans, and specifically, pigs, chickens, minks, quail, cows,
Horses, sheep, goats, dogs, cats, etc., among them, pigs, chickens,
Livestock with strong feces odor such as mink and quail are preferable.

[Action]

Recent advances in biotechnology have made it possible to grow a large amount of soil bacteria, and the metabolic function of the soil bacteria can produce phenol metabolites. When the livestock is allowed to drink the water in contact with the phenol metabolite, the odor of the feces of the livestock is significantly reduced, and odor prevention measures can be taken.

The theoretical background can be considered as follows. That is,
Domestic animals are aseptic while they are in the womb of their mother, but when they give birth, the bacteria from the outside world settle in, and a few days after the birth, countless bacteria such as Escherichia coli, enterococci, and lactic acid bacteria swarm in the intestinal tract and grow in the intestine. The inner flora begins to form.

For intestinal bacteria in livestock, 1) Suppress the growth of harmful bacteria (bad bacteria) that help digestion and absorption of feed that synthesizes vitamins, such as bifidobacteria and lactobacilli. Increases resistance to infection (immunostimulation). ) Control of cholesterol metabolites Control of blood pressure Synthesis of hormones, enzymes, blood sugar, etc. Beneficial bacteria that are useful in maintaining the health of livestock, and 2) Hazardous gases that promote intestinal decay such as Escherichia coli and Clostridia. Producing toxins Producing toxins There are bad bacteria groups that perform harmful functions such as converting nutrients such as amino acids into harmful substances.

There are many good bacteria groups in the intestinal bacteria of newborn breast-fed animals, and many bad bacteria groups in the intestinal bacteria of livestock that are not fed enough milk. It is known that there are few.

Taking piglets as an example, it is the fate of economic animals
At 21 to 25 days of age, they are forcibly separated from their sows and given artificial milk. This weaning shock and changes in the environment cause diarrhea and inconvenience, and if the condition continues for a long time, it will result in a poorly developed pig. The occurrence of diarrhea and stool is complicated by various factors, and one of the main causes is the disturbance of intestinal flora due to the decrease of beneficial bacteria and the increase of bad bacteria.

It is also known that the beneficial bacteria group convert amino acids such as phenylalanine, tyrosine, and tryptophan, which are important nutrients for livestock, into harmful spoilage substances such as paracresol, indole, and skatole.

According to the present invention based on these findings, the phenol metabolite generated by the metabolic function of the soil bacterial group has the effect of keeping the intestinal flora of livestock in a normal state with many beneficial bacterial groups, so that the phenol metabolism It is possible to keep the intestinal flora in a normal state with a lot of beneficial bacteria by allowing livestock to drink water that has come into contact with substances, and therefore, it significantly reduces the odor of livestock dung and takes odor control measures. Seems to be possible.

In addition, JP-A-63-141552 and JP-A-1-240152 disclose a technique for preventing an offensive odor of feces by using an additive or supplementary feed for livestock feed.

However, all of these technologies are related to feed, not to drinking water for livestock, and much less to suggest a manufacturing apparatus for drinking water for livestock.
