Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to livestock feed, particularly livestock feed containing corn leaves, stems and fruits as main components.

[0002]

2. Description of the Related Art Announcement of the "animal feed production apparatus by anaerobic fermentation" previously announced by the present inventors (JP-B-60-120)
Since 23rd patent No. 1290328), the use of drums as a livestock feed production apparatus by anaerobic fermentation has attracted great interest in the field of agriculture and forestry, and has been studied at agricultural test sites in various regions and is the subject of a subsidy system.

[0003]

However, it has been unclear in the past what kind of feed was effective for livestock and how. In Germany, I tried to manufacture it with a 2 m ³ tank made of stainless steel, but I stopped it because it is difficult to withstand pressure and seal well, and it can be used only once. In the past, livestock production was overly focused on the feeding method, which was to say what kind of feed to be given on the day after birth, even though the cattle had been raised for a long time. Instead of just high nutritional value, we should change the quality of the feed we feed, measure its efficient absorption, and raise it efficiently.

[0004]

The present inventors have found that it is convenient to use not only corn leaves but also stems and fruits, if any, as raw materials. Therefore,
It is convenient to use it as a raw material after cutting around the earliest period. If it is too large than the drum, the space between the corns will be large, and if it is too small than the drum, it will be difficult to pack and the space between the corns will also be large. Therefore, it has been found that the shape and size of a drum can are optimum for the present invention. Drums are best filled with corn cut to less than about 2 cm and there are few voids between corn.

The present inventors have also found that lactic acid fermentation under anaerobic conditions requires a pressure in the vessel of 0.6 kg / cm ² or less. When the pressure is higher than 0.1 kg / cm ² , the fermentation reaction proceeds rapidly, but when the pressure is 0.6 kg / cm ² or more, the fermentation reaction stops.

According to the present invention, corn leaves, stalks and fruits cut to a length of about 2 cm or less are placed in a drum type small container at a water content of 60 ± 8%, a pressure of 0.6 kg / cm ² or less, and a pH of 4. Five
Until the following, it is a livestock feed containing anaerobic lactic acid fermentation as the main component.

[0007]

The livestock feed of the present invention exerts a surprising effect on the growth of cattle. A feed of around pH 4.5 has a physiologically favorable effect on the rumen and rumen of cattle. Therefore, the pH of the animal feed of the present invention is set to 4.5 or less for production, but the fermentation is stopped when the pH value is not extremely lower than 4.5 and is lower than 4.5. The time when this happens depends on the outside air temperature, but it is about 7 days after the start of production, and if the outside air temperature is low, it will take a long time. Such livestock feed does not cause gasification in the stomach of cattle and therefore does not cause abnormal fermentation. In addition, diarrhea in livestock is significantly reduced.

It has been found that the container is convenient because the size of the drum can is approximately equal to the size of the rumen and rumen of a cow. Drums can be reused with a lid many times, so they are inexpensive and can be left beside a cornfield. The capacity of the drum can match the size of the rumen of a cow, which can be expanded and contracted to a size of about 200 liters, making it easy to pay.

When 10 kg of the feed of the present invention is fed to a cow per day, the calf gains weight at an astonishing growth rate of 1.6 kg / day and 584 kg / 365 days. This growth rate is an unprecedented growth rate. Therefore, since it can be shipped as an adult cow in an extremely short period of time, the feed can be saved and the cost of the adult cow can be reduced.
The reason why such early shipment is possible depends on the result of continuous feeding of the feed of the present invention. The feed of the present invention is extremely effective when fed alone, but when meat quality such as Matsuzaka beef is desired,
30% by weight of grains can be mixed in the feed after growth.

Energy is consumed up to about 6% when sealed during fermentation, but a good lactic acid fermented feed can be obtained in about 1 to 2 weeks.

In the present invention, since lactic acid fermentation is performed in an anaerobic state,
Corn is converted to high nutrients. It's not just about getting in and out of energy. In addition, it has a deodorizing effect on chlorophyll.

[0012] The quality of meat of cattle mainly grazing overseas is tinged with a reddish black color due to the effect of the melanin pigment, and it is unavoidable that it becomes hard when heat is applied. By avoiding absorption of phenolic substances, upgrading of meat quality and modification of pigments can be achieved. Be careful not to expose the cow to too much sunlight.

The feed of the present invention is easily absorbed about 2.5 times as much as the conventional feed, and a sufficient weight gain can be achieved by feeding 10 kg a day. In the case of conventional cattle breeding, the daily feeding amount is 20 kg and the weight gain is 0.9 kg, whereas the feeding amount of the present invention is 20 kg.
The weight gain was 2.3 kg.

It takes about one week for the cow to eat the feed, adjust the digestive conditions in the stomach in a short time, absorb it, and defecate, but the feed of the present invention makes the condition for absorption good and significantly shortens the time. . The cause of this is the lactic acid fermentation of corn, which is because the lactic acid fermentation was highly efficient. The effect is exerted from a continuous salary of 10 days or more. Therefore, intermittent pay is less effective and long pay is allowed. The salary is good from the time of calf. The content of saliva changes a little, the gastric juice with strong acidity and bactericidal effect becomes a little thin, and the number and action of microorganisms in the stomach become active.

The feed of the present invention is 12 between the drums per day, which is 12 per day.
It becomes the feed for the head cow. It is possible to raise 55 cows a year in 1 ha of corn field. Large corn fields of 50-100 ha
3000 heads can be raised easily. And the breeding cost is about 1/3 of the conventional
Rank

The low-pressure gas generated during the sealing enters the cells of corn to facilitate decomposition and digestion.

Corn is inexpensive and can be harvested in large quantities. 6 tons per 10 a can be harvested in Japan and 20 tons per 10 a in the United States.

According to the present invention, the amount of salary required is 1/2, and the growing period is 1/2. Therefore, the feed fed is 1/4.

When the feed of the present invention is fed, the action of many microorganisms in the stomach of cattle is activated, and the absorption efficiency of the fed feed is increased.

When the feed of the present invention was fed, the amount of lactic acid bacteria was large, and the number of general bacteria and mold was small, so that the death of cattle was remarkably reduced and it was reduced by about 96%.

Further, when the feed of the present invention is fed, the quality of meat of cattle becomes good. It takes 15 people to keep 3000 heads.

As fermentation progresses, gas is generated and the pressure in the vessel rises. The pressure reducing valve works at 0.3 kg / cm ² and the maximum pressure of about 738 kg is applied to the plane of the container. The nutritional value of feed tends to decrease as the amount of generated gas increases. 15
At a temperature of about ℃, the generation of gas subsides within about 10 days.

The feed of the present invention can be sold by sealing it in a can, a bag or the like. The invention will now be described in more detail with reference to examples.

[0024]

Example 1 Corn leaves, stems and fruits were cut to a size of about 2 cm or less, 125 kg was press-fitted into a drum, moisture was 65%, and pressure was 0.3 kg / cm ^2.
Then, when 12 kg per day of the feed of the present invention, which was produced by leaving it in the field at an atmospheric temperature of 18 ° C for 7 days until the pH became 4.5 or less, about 40 kg of Holstein calf gained about 1.4 kg per day. However, in one year, it weighed about 600 to 650 kg, and it could be shipped, and forced breeding was achieved. During this period, the calves were not sick, were extremely healthy, and the meat quality was as good as ever.

Although the present invention has been described in terms of particular examples and numerical values, it should be understood that various changes and modifications can be made without departing from the broad spirit of the present invention.
