Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to milk for lactating pigs using cow colostrum.

Recently, milk substitutes for first-year pigs, that is, milk for pigs during their lactation period, are being used to: ■ Wean piglets early to improve the breeding turnover rate of sows; Various research and development efforts have been carried out for the purpose of: ■ giving excessive doses to piglets; and ■ giving them to nursing sows in the event of an unexpected accident. Since this occurs only through milk, it is an important issue how to make immune antibodies derived from colostrum, and bovine colostrum is being used as one way to solve this issue.

Cow colostrum naturally provides immunity to calves and prevents diarrhea and other disease infections, but calves that are separated from their mothers after birth and forced to drink pig colostrum are It is known that, even though it is a different animal species, immunoglobulin in cow colostrum is taken up by the piglets, although the level is low.

However, colostrum from cows is difficult to obtain in large quantities and needs to be stored at all times, but except for short periods in the winter, bacteria and other organisms multiply extremely rapidly, so it is not normally stored. If cow colostrum is fed directly to piglets, it often causes diarrhea.

Therefore, various preservation methods are used, and one of the preservation methods is Streptococcus lactis (5tre
ptococcus 1actis ), Lactobacillus bu
Research has been conducted on methods of lactic acid fermentation using which lactic acid bacteria (Immuno globulin G.
), I gA (I mmun.

globulin A), IgM (Immuno
globulin M) zI gE (Immun
o Globulin E) i) Bovine immunoglobulins have the disadvantages of little transfer to piglets, low effectiveness in preventing diarrhea, and poor growth in terms of growth.

Furthermore, since it is said that immunoglobulin tends to lose its effectiveness when heated in the presence of lactose, other preservation methods are known, such as refrigeration and freezing, rather than heat-drying. This method is not only difficult to handle, but also requires equipment such as a refrigerator, so it is not popular.

On the other hand, synthetic milk substitutes are commercially available as substitutes for breast milk, but these milk substitutes mainly contain milk ingredients such as skim milk powder, dried whey, and dried buttermilk, as well as high-quality grain flour,
It is a mixture of protein feed, micronutrients, etc., and is given to piglets following the feeding of colostrum, and no consideration is given to the development of immune antibodies.

Furthermore, commercially available artificial milk is fed to piglets following the above-mentioned milk replacer, and as with the above-mentioned milk replacer, no special consideration is currently given to immune antibodies.

Under these circumstances, the present inventors conducted intensive research to commercialize cow colostrum as milk for suckling pigs. As a result, spray-dried cow colostrum was found to be a representative immunoglobulin when processed. In addition, we found that the rate of transfer into the serum of piglets was extremely good, with less loss of IgG, which makes up the majority of the IgG, and that the addition of vitamins and minerals made the growth effect of piglets even worse. Based on this, the present invention was completed.

That is, the present invention is a milk for lactating pigs which is made by spray-drying cow colostrum itself or cow colostrum to which vitamins and/or minerals have been added. When piglets are kept apart from their mother pigs due to accidents, rescue of excess offspring, prevention of disease infection due to contact with mother pigs and mother pigs, or economic considerations for breeding, it is recommended to replace mother's milk. Has the function of an immune antibody,
It is an object of the present invention to provide milk for lactating pigs that has good growth, good storage stability, and is easy to handle.

Hereinafter, the present invention will be explained in detail.

The colostrum of cows used in the present invention is from within 5 days after calving.

Since these products contain a large amount of whey protein, if they are heat-coagulated and used as a raw material for commercial milk, there is a risk that the product value will be significantly impaired, so shipping and sale as raw materials for commercial milk are prohibited, but the present invention Colostrum within 2 to 3 days after delivery is suitable as a raw material.

Spray-dried cow colostrum can be quite effective in terms of immunity even if it is dissolved in water or hot water and given to piglets separated from the mother, but it may be lacking in vitamins and minerals. It is preferable to add vitamins and minerals to prevent skin irritation, peeling of the skin surface, and damage to the legs and joints.

Examples of vitamins to be added include vitamin A, IL
EI K3 m Bl * B2 t B6 eB, 2
．． C, niacin, pantothenic acid, folic acid, hyotine,
Examples of minerals include copper, iron, zinc, manganese, iodine, and cobalt, which are appropriately selected and added.

These vitamins and minerals can be made into a lactose-based premix and added to cow colostrum that has been spray-dried and powdered, but in order to mix them uniformly, they must be added to cow colostrum in advance. Preferably, they are mixed and spray dried to a powder.

In this case, the amount of vitamins and/or minerals added is preferably about 0.01 to 0.5% based on the solid content of cow colostrum.

Next, in the present invention, cow colostrum itself or cow colostrum to which vitamins and/or minerals have been added is spray-dried to form a powder, but pretreatment such as vacuum concentration is performed before spray-drying. Good too.

The spray drying method may be a method using a rotating body such as a rotating disk or a rotating nozzle, or a method using a fixed nozzle, but the manufacturing conditions are that the air temperature is 120 to 150°C and the outlet temperature is 70 to 80°C. , the product temperature is 50-60
It is desirable to set the temperature to ℃.

Pig lactation milk obtained by spray-drying cow colostrum as described above is dissolved in water or hot water to a concentration of 10 to 30% and given to piglets, and a synthetic milk substitute is mixed with this. It can also be used as

In particular, if the cow's colostrum is used as the raw material until the second day after parturition, even if about half of the amount is supplemented with synthetic milk replacer, it will completely prevent diarrhea in piglets that do not drink any of the sow's colostrum. It is possible to prevent this, and if you are prepared for some diarrhea and try to make up for it with better hygiene management, you can increase the proportion of synthetic milk substitute in the mix.

For example, it is effective to use 50 parts or more of the lactation milk of the present invention from 1 to 5 days of age, and gradually reduce the usage rate of the lactation milk of the present invention as the baby ages.

The milk for suckling pigs of the present invention is dissolved in water or hot water for 10 to 10 minutes.
Concentration of about 30%, 4 to 24 times a day, 15 to 901
If approximately 100ml of bovine immunoglobulin is given to piglets that do not drink the mother's colostrum at all or in sufficient quantity using a feeding pin or feeding dish, bovine immunoglobulin can also be transferred into the piglet serum. The results are very good, and the piglets grow without diarrhea, and their growth is also very good.

Furthermore, although the milk for suckling pigs of the present invention is mainly intended for piglets up to 21 days old that are isolated from their mother pigs, it is suitable for piglets that have diarrhea after drinking synthetic milk substitute. If the above-mentioned milk is fed, it has a therapeutic effect of recovering from diarrhea in 2 to 3 days, so it can be applied.

Furthermore, since the pig milk for suckling of the present invention is usually in the form of a dry powder, it has an extremely good shelf life, and is extremely easy to handle since it can be used by simply dissolving it in water or hot water.

Next, the effects of the pig lactation milk of the present invention will be explained with reference to experimental examples.

Experimental Example 1 Piglets were placed in an automatic nursing device immediately after birth, and fed with the lactating milk of the present invention obtained in Example 1 described later, bovine colostrum fermented with lactic acid, and commercially available liquid synthetic milk replacer. 24 a day
Each time, 15 to 35 ml was automatically fed.

Then, bovine IgG in the piglet serum was measured 24 hours and 48 hours after birth.

The results are shown in Table 1. The milk for lactation of the present invention is given by adding water and mixing the solids content to a concentration of 20 parts, and the lactic acid-fermented cow colostrum is Lactobacillus bulgaricus (L-bulgaricus).
) starter and Lactobacillus acidophilus (
L. acidophilus) starter was added and lactic acid fermentation was carried out.

From the above results, it is recognized that when the lactation milk of the present invention is given, the transfer of bovine IgG into piglet serum is high.

In addition, the piglets fed the lactation milk of the present invention had less occurrence of diarrhea and had good growth.

Experimental Example 2 A test similar to Experimental Example 1 was conducted using the supplementary milk of the present invention obtained in Example 2 described later and cow colostrum fermented with lactic acid in the same manner as described in Experimental Example 1. 12 hours after birth, 2
Bovine IgG in the piglet serum was measured 4 and 60 hours later.

The results are shown in Table 2, and it was found that the transfer of bovine IgG into the serum of piglets fed the lactation milk of the present invention was high.

In addition, piglets fed the lactation milk of the present invention did not develop diarrhea and had good growth.

Experimental Example 3 Piglets were housed in an automatic nursing device immediately after birth, and milk for lactation of the present invention obtained in Example 2, cow colostrum fermented with lactic acid in the same manner as described in Experimental Example 1, commercially available Each of the liquid synthetic milk substitutes was fed in the same manner as in Experimental Example 1, and the weight of the piglets in each group was measured.

Furthermore, the groups that were fed the lactating milk of the present invention and lactic acid-fermented cow colostrum were fed liquid synthetic milk replacer after 9 days of age.

The results are shown in Table 9.

However, the results are the average of the four horses in each ward. In the group fed the milk for suckling of the present invention, no diarrhea occurred and the growth was extremely good.

Next, examples of the present invention will be shown.
