Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a feed for suckling piglets containing egg powder, and particularly to a milk replacer for day-old pigs.

[Conventional technology]

In order to improve productivity in pig farming management, it is important to increase the growth rate of piglets and improve their growth performance. Factors that reduce the growth rate of piglets include ■ Death of the sow ■ Low milk production of the sow ■ Too many piglets and not enough milk ■ Piglets are weak and cannot suckle adequately. In order to solve these factors, increase the growth rate of piglets, and improve their growth performance, the characteristics of feed for suckling piglets that are required are good palatability, high penetration, and weaning. Conventional finely powdered feed for suckling piglets has been granulated into granular feed because it reduces stress, promotes smooth growth, and allows piglets to grow healthily. However, it is still not as satisfactory as pig's milk. On the other hand, so-called milk substitutes for suckling piglets have been attempted, in which these powdered feeds or granular feeds are dissolved in water or hot water and given to piglets to drink. It has disadvantages such as poor solubility when dissolved in hot water.

[Problem that the invention seeks to solve]

The present invention improves the palatability and solubility, which are the drawbacks of conventional feeds for suckling piglets, and when fed to suckling piglets, increases the piglet's appetite, increases food intake, and improves palatability and solubility. The aim is to provide feed that can improve the amount of pay and raise energetic piglets.

[Means for solving problems]

The inventors of the present invention have conducted various studies to solve the above-mentioned problems, and found that after blending chicken egg powder into feed for suckling piglets, granulation and drying were carried out, and the feed for suckling piglets was dissolved in water or hot water. The present invention was completed by discovering that the above-mentioned problems could be solved by feeding the animal or feeding it as is.

That is, the present invention is a feed for suckling piglets, which is characterized by blending chicken egg powder into the feed for suckling piglets, granulating it, and drying it. We provide a feed for suckling piglets that is easy to penetrate and has good solubility when dissolved in water or hot water, which reduces the weaning stress of piglets and eliminates the occurrence of diarrhea.
The purpose is to raise piglets in a healthy manner.

Egg powder to be added to feed for suckling piglets should preferably be powdered after freeze-drying or powdered by spray-drying, and even if spray-drying is used, it is desirable to process at a temperature of 50°C or below. . Further, the amount of egg powder to be blended may be appropriately selected within the range of 0.5 to 10%.

In the present invention, raw materials other than egg powder for piglet feed include milk powder, which includes skim milk powder, whole milk powder,
Dried whey, milk casein, etc. are mentioned, and raw materials other than powdered milk include wheat flour, unfloured flour, bread crumbs, dextrin, grains such as wheat, corn, corn starch, and yellow powder; soybean oil cake.

Vegetable oil cakes such as dehulled soybean meal, concentrated soybean protein, isolated soybean protein; Animal feed such as fishmeal; Sugar, lactose, glucose,
#Ns such as fructooligosaccharides, galactooligosaccharides, lactulose, and isomalto-oligosaccharides; animal and vegetable fats and oils such as beef tallow, lard, milk fat, soybean oil, coconut oil, and cacao butter;
These include vitamins and minerals, flavors, sweeteners, enzymes, emulsifiers, organic acids such as citric acid, tartaric acid, malic acid, fumaric acid, lactic acid, and others. , can be arbitrarily selected and used.

In normal feed for suckling piglets, milk powder such as skim milk powder is used in a range of about 15 to 75%, but in the present invention, if egg powder is used, skim milk powder is destroyed, and soybean isolate protein is used to destroy it. It is also possible to make a nutritionally satisfying feed for suckling piglets by supplementing the amount of the feed.

Next, in the present invention, chicken egg powder is blended into piglet feed, and the feed is granulated and dried.

As the granulation method, various granulation methods such as fluidized bed granulation, high-speed stirring granulation, and crushing granulation can be used.

In the present invention, since feed materials such as milk powder and egg powder are used, granulation can be performed by adding approximately 3 to 5% water, but when granulating by fluidized bed granulation, the amount of water added should be selected appropriately. It may be granulated.

If the particle size of the feed is increased, it will be difficult to dissolve in water, and if fed as feed, it will be difficult to chew, so it is desirable to granulate the feed to an extent that improves fluidity.

The granulated product has a moisture content of approximately 10% or less, preferably 8%.
Dry as shown below. At that time, it is desirable to dry by blowing warm air, but if the temperature is too low, the drying efficiency will be poor, and if the temperature is too high, the nutritional components of the feed for suckling piglets will be lost, so the temperature should be kept at around 60-100°C. The temperature of the product after drying is 60.
It is desirable to keep the temperature below °C. However, if the raw material is granulated under conditions where the moisture content is low, it is also possible to dry at a lower drying temperature.

Various types of dryers can be used, such as ventilation dryers and fluidized bed dryers, but it is particularly desirable to use a fluidized bed dryer.

When the feed for piglets of the present invention is dissolved in water or hot water and fed to piglets as milk, it is preferably dissolved in about four times the amount of water or hot water and fed.

〔Example〕

EXAMPLES Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited thereto.

Example 1 After crushing and mixing feed for suckling piglets not shown in Table 1, it was fed into a cylindrical continuous mixer at a feed rate of 7.50 kg/11, and at the same time water was added to the feeder at a feed rate of 22.5 kg by external grinding. /11 was added and granulated, then put into a fluidized bed dryer and heated at 70°
The feed A for suckling piglets of the present invention was obtained by drying with hot air of C.

Milk for piglets was prepared by dissolving each of A and B in Table 1 in 4 times the amount of water, and the milk was fed to each of 7 piglets immediately after birth, and raised in combination with mother's milk for 21 days. The results are shown in Table 2.

Table 2 Next, as a control, control feed B for suckling piglets was obtained in the same manner as test feed A except that the raw materials for control feed B in Table 1 were used.

In addition, the prepared milk of the feed for suckling piglets of the present invention, which was obtained as described above, was liked by piglets and had good feeding performance.

〔Effect of the invention〕

The feed for piglets of the present invention is blended with egg powder and is granulated and dried, so it has high fluidity and can be adapted to mechanization and labor saving such as automatic feeding in pig farms, and does not cause bridging in feeders. do not have. In addition, when dissolved in water or hot water and fed to piglets, it has good fluidity, so it is easy to handle and has excellent solubility, and because it contains chicken egg powder, it is palatable and easy to eat for piglets. Some of the benefits include that the piglets have a lot of bite and grow well. In addition, when feeding conventional piglet feed as milk, there were disadvantages such as the piglets being prone to diarrhea, but the feed for suckling piglets of the present invention contains egg powder. There are no such adverse effects, and it can reduce weaning stress and promote smooth growth.
