Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cow with a low morbidity, a calf that grows in a well-balanced manner,
The present invention relates to a bovine nutritional supplement suitable for growing a dairy cow that produces milk having a high milk fat content.

(Prior Art) Generally, in raising and managing cows, consideration must be given to differences such as bulls and cows, beef and dairy cows, calves and parent cows. For example, for cows, there are problems such as difficult birth and waist loss.
For dairy cows, the feed should be managed in consideration of the problem of mastitis and the growth problem of calves.

By the way, as a general feed for cattle, green grass is fed from May to August, and dry grass is fed from September to April, but the green grass contains enough nutrients. Therefore, the milk fat content of milk in the milk fed to the green grass farm is in the range of 3, 3 to 3 and 4%. On the other hand, dry grass has a higher nutritional content than green grass, but feeding of either green grass or dry grass reduces the morbidity of cattle, results in well-balanced growth, or milk with a high milk fat ratio. In order to produce, it is necessary to provide nutritional support.

Therefore, in addition to the above-mentioned general feed, for example, Japanese Patent Publication No.
Feeding a granular mineral mixed feed as shown in Japanese Patent Publication No. 8-35066 or a nutrition feed containing various vitamins,
Alternatively, the milk fat ratio is increased by feeding a feed containing a predetermined amount or more of crude fiber.

(Problems to be solved by the invention) By the way, although the feed cost accounts for a large proportion of the cost of dairy farming, the above-mentioned nutritional feed of the prior art has a higher price than general feed, so that the burden on the dairy farmer is also high. There is a big one. Particularly in recent years, milk having a high milk fat content has been in demand as high-quality milk, so that there is a problem in that nutritional feed must be fed with the knowledge that the feed cost will increase.

Further, in order to maintain a predetermined milk fat ratio, it is said that 13 to 17% or more of crude fiber needs to be contained during the drying of the whole feed, but this content varies depending on the type of feed and the feeding method. Therefore, there is also a problem that the dairy farmer has trouble with the mixing work.

Further, since the conventional nutrition feed is a chemically synthesized feed, there is a risk that the cow will be burdened and the growth balance will be lost if the feed amount is excessive.

The present invention has been made as a result of intensive research conducted by the inventor in view of the above-mentioned problems of the prior art, and has excellent effects such as improvement of milk quality, growth, and reduction of morbidity, and lower than conventional nutrition feed. Provided is a nutritional supplement for cattle (hereinafter referred to as "auxiliary material") which can be manufactured at a low price and can be safely fed as a natural nutritional supplement that does not burden the cow.

(Means for Solving the Problems) Means of the present invention, which is configured to solve the above-mentioned problems, is a feed base 60 that is obtained by removing starch from potatoes.
It is produced by mixing 70% by weight with 40 to 30% by weight of liver oil.

(Examples) Hereinafter, examples of the present invention will be described in detail.

First, a so-called potato feed is used as the base of the auxiliary material. This potato feed is made by removing starch from potatoes to form flakes close to powder, and is widely used as a cheap feed for livestock. The components are as shown in Table 1.

On the other hand, the liver oil to be blended in the potato feed is preferably taken from the liver of codfish, especially smelt. The general method for obtaining liver oil of smelt and cod is as follows. The liver taken out from the fish is heat-treated by blowing steam in the container. The liver liquefied by heat treatment is centrifuged to separate oil from water and solids. A liquid liver oil can be produced by filtering the finally obtained oil with a filter paper or the like.

The components of the liver oil thus obtained are shown in Table 2.

In Table 2 above, retinol was analyzed by the Karl Price absorptiometry and vitamin D was analyzed by high performance liquid chromatography. It can be seen from Table 2 that liver oil contains an extremely large amount of vitamin A, which has an effect of promoting the growth of livestock including cattle, and its content is different from that of other foods. It has reached about 100 times.

The auxiliary material of this example is the above-mentioned potato feed and liver oil.
It is a completely new product produced by mixing at a ratio of 0 to 70% by weight to 40 to 30% by weight. By setting this mixing ratio, there is a great effect on the production of milk having a high milk fat ratio, the reduction of the incidence of mastitis, the reduction of the incidence of so-called "lumbago", the promotion of the growth of calves, etc. Since it uses the above ingredients, it does not impose a burden on cattle and can be produced at an extremely low price as compared with conventional nutrition feed. First, Table 3 shows the components of the auxiliary materials according to the examples.

From this table it can be seen that in the auxiliary material 52,70
Contains 0 IU / 100 g of vitamin A, and the required amount of vitamin A in milk (concentration in dry matter of feed) is 3,200 I
Since it is U / kg, the content of vitamin A in the auxiliary material is extremely high. Also, 5 in the auxiliary material
Contains 90 IU / 100 g of vitamin D, and the required amount of vitamin D in milk (concentration in dry matter of feed) is 300 IU
Since it is / kg, the content of vitamin D is also high.

Now, the above-mentioned auxiliary materials are fed together with hay. It is suitable to feed 50 g per day to the breeding cows, but it is advisable to feed the young and pregnant cows with appropriately increased or decreased amounts, and about 100 g to the lactating cows.

Next, Table 4 shows changes in the milk fat ratio in milk before and after feeding the auxiliary material.

It can be understood from Table 4 that by feeding 100 g of the auxiliary material per day, the milk fat ratio is 0.2% compared to before feeding.
It is possible to increase the points. And by increasing the milk fat ratio by about 0.2 points, butter,
As a high-fat milk for ice cream, it can expand its demand and improve its profit.

Further, the increase in the milk fat ratio due to the feeding of the auxiliary material can be easily understood from the figure showing the change in the milk fat ratio by year.

Next, the effect of the bovine nutritional supplement of the present example will be described by taking as an example a farmer who runs a small-scale dairy farm with 50 dairy cows.

(A) About the milk fat ratio. Compared to the previous year when supplements were fed, the milk fat percentage one year after the start of feeding increased by 0.3 to 0.5 points. With the increase in the milk fat ratio, the milk price also increased, and the income increased about 40 times the cost of the supplement.

(B) About the so-called "loose waist" that appears after giving birth.
Since the cows that become “stuck” lose their value as dairy cows, it becomes a very serious problem for dairy farmers that feed cows become “stuck”. Table 5 shows the effect of the auxiliary material on this "stiffness" phenomenon.

(C) About mastitis. Mastitis control is an important concern for dairy farmers because mastitis milk produced from mastitis cows causes low acidity secondary milk. The auxiliary material of the present example is also effective as a countermeasure against mastitis, and the number of mastitis cases in 50 cows was 10 before the salary (incidence rate 20%), but 5 (after the supplementary material was supplied). The rate was reduced to 10%).

(D) In addition, regarding the effect confirmed as a result of continuously supplying the auxiliary material for 6 months or more. The period required for a young beef cattle to grow to 300 kg, which is a target for trading, can be shortened by one month from the conventional one, and it can be grown to 300 kg in 5 to 6 months. Further, the morbidity of rickets, osteomalacia, night blindness, keratomalacia, etc. could be reduced.

Furthermore, by feeding supplementary materials to pregnant cows one month before the expected date of birth, it was possible to reduce the incidence of dystocia.

The effect of feeding the auxiliary material of this example is as described above, and liver oil 40 to 60 to 70% by weight of potato feed.
It is significant that the blending ratio is ˜30 wt%. That is, if the ratio of liver oil to potato feed exceeds 40% by weight, cattle will have too much fat,
In particular, beef cattle lose their commercial value, and cows are less likely to become pregnant.

On the other hand, if the blending ratio of liver oil to potato feed is less than 30% by weight, there is a problem that milk fat, which is the basis of the calorie source of milk, does not increase.

In addition, liver oil does not solidify even at temperatures below −0 ° C., and since liver oil purified with filter paper retains its liquid state even at −5 ° C., it is extremely easy to mix potato feed with liver oil even in winter in cold regions. Since it does not solidify in the bait box, feeding work is not hindered.

Since the auxiliary material of this embodiment is a so-called natural food as described above, other natural or artificial nutritional material may be added to the auxiliary material and fed.

(Effects of the Invention) The present invention is as described in detail above, wherein 60 to 70% by weight of a feed base obtained by removing starch from potatoes is used to prepare natural liver oil 4.
Since the composition contains 0 to 30% by weight, it is highly effective in improving milk quality, preventing morbidity of cattle and promoting growth as a result of containing abundant vitamins, and is safe because it uses natural raw materials. It can be used as a nutritional supplement for cattle that can be fed with care. Further, since it is produced using only potatoes and liver oil as a raw material, it can be produced at an extremely low cost as compared with the conventional technique, and the feed cost which occupies a large weight in dairy farming can be significantly reduced.
