Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide an anti-gastric ulcer feed for pigs. The invention relates to feed for pig farming.

In recent years, as the scale of pig farming has expanded, gastric ulcers have become more common, resulting in many pigs dying or suffering from stunted growth and having to be culled midway through the production process, which is the main cause of accidents and losses.

Feeding roughage such as cowhide, hay, and silage rice straw has traditionally been considered effective to some extent in preventing gastric ulcers in pigs.

However, this roughage has disadvantages such as uneven quality, complicated breeding management and equipment, and difficulty in seasonal and local availability, and feeding large amounts of roughage is not economical. You can't expect the appropriate growth.

On the other hand, attempts have been made to coarsen the grinding of corn and oats, to mix rice straw, rice husk, hay cubes, sawdust, etc. into the feed, and to solidify the feed, but all have yielded satisfactory results. has not been obtained.

The inventors of the present invention have conducted various studies to improve conventional pig feeds that have these drawbacks, and have developed a feed for pigs that prevents the occurrence of gastric ulcers and allows for healthy growth. This led to the invention of feed.

That is, the present invention is a pig feed prepared by solidifying a composition containing whole grains with skin or crushed or crushed grains and beet pulp as main components.

The whole grains with skins used in the present invention include, for example, grains with skins such as barley, oats, wheat, barley, rye, corn, milo, millet, millet, and millet.

At this time, use whole grains with the skin on, or
Depending on the case, it may be used after being roughly crushed or pressed.

Next, the beet pulp used is one obtained by roughly crushing dried beet pulp pellets, or one obtained by appropriately crushing compressed and packaged beet pulp.

The blending ratio of these is mainly 40 to 90% whole grains with skin, preferably 60 to 80%, and 10 to 40% beet pulp, preferably 15 to 20%, and if necessary, it can be used in general feed. Rice bran, animal protein sources, honey, fats and oils, and other additives such as vitamins and minerals are used as is.
Or crush it and cut it into pieces.

In solidifying the above composition, for example, using a pellet mill, diameter 4 to 20 r IL r IL 1 length 4
It is made into a solid product with a size of ~40 mm.

In this solidification step, it is preferable to spray steam or add water to the mixture, so that the solidified product is hard and has less shear.

When feeding the solid feed of the present invention, it is only necessary to feed it as is, and there is no need to feed roughage or the like.

By feeding this solid feed, normal decomposition occurs in the pig's stomach (which cannot be obtained with other compositions or other physical forms) and an appropriate stimulating effect on the stomach wall. Prevents stomach ulcers and shows normal development.

In this case, the physicochemical properties in the stomach are exactly the same as when a large amount of roughage is used in combination.

In other words, solid foods do not break down easily in the stomach, decompose gradually, absorb water, and gradually swell to give a suitable bulk in the stomach. Because it stimulates the stomach wall, it exhibits an effect not seen in conventional feeds with large grain sizes or simply solidified feeds.

As described above, if the feed of the present invention is used, it is not necessary to feed roughage or the like to first breed pigs, and normal economic production can be carried out using only the feed.

The results of a pig breeding test showing the effectiveness of the solid feed of the present invention will be described below.

The test pigs were a total of 22 LWH (three-way cross-bred pigs of Landrace, Large York, and Bambusha) weighing an average of 37 kg, and 11 pigs in each section were group-housed in concrete pig pens.

District 1 uses commercially available solid feed for fattening pigs.
In the second group, the solid feed according to the present invention shown in Example 1 below was fed.

The results of rearing for 84 days are shown in Table 1.

In addition, the commercially available feed for pigs in the table is a mixture of crushed grains (milo, corn), soybean meal, wrinkles, fishmeal, charcoal, phosphorus, salt, vitamins, minerals, and molasses. , gastric test results indicate that the condition is severe in the order of keratosis, erosion, and ulcer. Keratosis is a condition in which the gastric wall mucosa wrinkles and hardens like elephant skin, and erosion is a condition in which the stomach wall becomes inflamed. A state that occurs.

In addition, the feed conversion ratio indicates the amount eaten/the amount gained. As above,
The condition and growth of the stomach were extremely normal and showed a large difference from commercially available solid feed.

An example of raising meat pigs in cages is also shown.

The test pigs were a total of 20 LWD pigs (a three-way cross between Landrace, Large York, and Durotsuk), with an average weight of 31.5.9.

Area 1 uses solid feed for fattening pigs that is generally commercially available, and area 2.
A solid feed according to the present invention shown in Example 2 below was fed to the group.

One animal in each group was raised in a metal cage and a fattening test was conducted for 98 days. The results are shown in Table 2.

Table 2 Results of pig fattening test in cages As shown above, the method of the present invention showed extremely good effects in terms of both stomach test results and growth.

These results show that even in the case of pigs raised in cages, feeding according to the present invention prevents the occurrence of gastric ulcers, and the pigs show excellent growth as meat pigs, which clearly demonstrates the effectiveness of the present invention.

Next, examples of the present invention will be shown.

Example 1 (for pork fattening) 30% whole barley with skin, 25% ground milo,
Pelletized beet pulp with 2.5% molasses added, 32% crushed soybeans, 10% soybean oil cake, 1% animal fat, 0.5% salt, 1.5% vitamins and minerals. After mixing thoroughly with a mixer.

Water equivalent to 2% of this mixture was added and further mixed, and after leaving to stand for 16 hours, the composition was milled in a pellet mill using a 3/16 Inochidai, with a diameter of 4.5 mm and a length of 12 mm.
I finished it as my solid object.

Example 2 (for pork fattening) 53% barley in round eggs with skin, 20% lightly pressed oats with skin on a smooth roll, 15% coarsely crushed beet pulp pellets without molasses added , 7% linseed oil cake, 3% molasses, 0.5% salt, 1.5% vitamins and minerals were thoroughly mixed in a blender, and then steam was blown onto this composition using a pipe with a diameter of 20 mm. Tsu\,
The pellets were charged into a hopper of a pellet mill and solidified using a 5 mm die to a diameter of 5.5 mm and a length of 15 mm.

Example 3 (for breeding adult pigs) 15% ground corn, 27% whole oats with skin, 5 to 20% compressed and packed domestic beet pulp
20% crushed into WL1rL size, 13% rice bran oil cake, 20% soybean oil cake, 3% molasses, 0.5% salt,
After thoroughly mixing 1.5% of vitamins and minerals in a mixer, adding water equivalent to 3% of the total and mixing thoroughly, this mixture was passed through a 3/8 inch die in a pellet mill. It was solidified to a diameter of 9.5 mm and a length of 20 mm.
