Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semi-humid granular feed for young animals containing a milk protein substance as a main component.

Conventionally, semi-moist animal feed (semi-moist food) containing fish and meat, fish and meat by-products and other animal raw materials, vegetable raw materials such as grains, vitamins, minerals and other raw materials has been well-known. A flexible pet food for household stock, especially for dogs and cats, is disclosed, which comprises a protein material such as grain powder, a fish lysate, a colloidal material such as milk protein, and is coated with a moisture element. However, these are soft feeds that are fed to dogs and cats, so-called pet animals, and are unsuitable feeds for raising cows, pigs, or young laboratory animals. Further, a powdered solid milk substitute composition comprising dry skim milk, dry skim whey, yeast powder, and starch material is disclosed,
This is a powdered feed, which is uneconomical because it scatters when fed, and when it is made into a liquid feed, it requires time and effort to disperse it in water or milk, making it difficult to use when raising a large number of animals. is inconvenient.

The present inventors are involved in raising large numbers of calves and piglets in conjunction with the expansion of dairy farming, the fattening of beef cattle and pigs, and the breeding of dairy cattle, or the toxicity testing of drugs and food additives, biochemicals, and physiology. Semi-moist granular feed (semi-moist food) is suitable for raising and breeding young experimental animals that are often used in academic research, and can be easily fed.
As a result of various researches on the subject, the present invention was achieved.

INDUSTRIAL APPLICABILITY The present invention can be suitably used as artificial milk or milk substitute for raising large numbers of young meat or dairy cows, meat pigs, or experimental animals, and has high storage stability. The purpose is to provide a semi-moist granular feed for young animals such as cattle, pigs or laboratory animals.

Another object of the present invention is to provide a soft (semi-moist) granular feed for early weaning for the above-mentioned young animals.

The present invention provides a semi-moist granular feed containing 30% by weight or more of milk protein as a main component and having a moisture content of 20 to 30% by weight.
A semi-moist granular feed for young cattle, pigs or laboratory animals (hereinafter also simply referred to as semi-moist granular feed) characterized by having a water activity of 0.93 or less in weight%. .

In the present invention, young animals refer to calves, piglets, or laboratory animals in the lactation stage, and laboratory animals refer to animals used for toxicity tests, such as mice, rats, hamsters, or monkeys. means.

In addition, milk protein products used as raw materials in the present invention include dairy products and/or milk such as skim milk powder, dry whey powder, casein, casein soda, lactalbumin, and other demineralized whey protein concentrates. One or more milk protein feed raw material powders selected from product by-products are used.

The raw materials used in the present invention other than the milk protein feed raw material powder selected from the dairy products and/or dairy by-products are selected from flour, maikuchi, corn, etc. that are puffed or not. Starchy feed raw material powder, saccharides selected from sugar, glucose, lactose, high fructose sugar, dextrin, etc., and feed-grade oils and fats selected from soybean oil, powdered oils and fats, and other oils and fats are used. , anti-inflammatory agents and other materials include propylene glycol, bunalene glycol, potassium sorbate, sodium sorbate, calcium propionate, calcium phosphate, glycerin, antibiotics, antibacterial substances, antioxidants, probiotics or vitamins. If necessary, gelanan, agar, extracted soybean protein, fish and animal meat meal, bone meal, and other feed materials commonly used as feed materials can also be used as appropriate.

In the present invention, the water content is 20 to 30% by weight,
In addition, by containing milk protein at 30% by weight or more, palatability to young animals is significantly improved and feed intake is increased, and milk protein components suitable for the developmental period can be provided. Combined with the feed ingredients, this results in faster growth in young animals.

In addition, by setting the moisture content to 20 to 30% by weight, a soft granular semi-moist feed that is easy for young animals to eat can be obtained. cannot be maintained at 0.93 or less, making it difficult to suppress the proliferation of bacteria and germination of mold over a long period of time, making it difficult to store the product for a long period of time.

An appropriate method can be used to produce the semi-moist granular feed for young animals of the present invention.

For example, a predetermined amount of milk protein feed raw material powder and other feed raw materials are mixed so that the milk protein content is 30% by weight or more, and water is added to this so that the moisture content is 20 to 30% by weight. Processing methods such as cross-wiring, extrusion, and cutting are used.

When heating in the molding process, it is preferable to perform the process at a temperature that is not too high, and it is preferable to impregnate heat-unstable feed materials such as vitamin C after molding.

Next, the actual winding mode of the present invention will be described.

Actual case 1 (example of feeding to piglets during nursing period) 12 litters 1
02 piglets in the lactating period were divided into a test group in which they were fed with the semi-moist granulated feed of the present invention having the following composition and a control group in which they were fed with powdered piglet artificial milk having the following composition. Each animal was reared for 3 weeks from immediately after birth until weaning.

As shown in Table 1, the test group had 5.9 times more feed intake and about 23% more weight gain than the control group.

Next, the composition and moisture content of the feed will be described.

The artificial milk for piglets in the control group had the same composition as the feed in the test group, but the propylene glycol 4% alcohol was replaced with heated corn (extracted corn).

In addition, the moisture content is based on the official moisture analysis method specified by the Fertilizer Inspection Center of the Ministry of Agriculture, Forestry and Fisheries.

Leprosy Example 2 (Example of feeding to weaned piglets) 62 weaned pigs were fed the semi-moist granular feed of the present invention described in Actual Example 1, and the powder used in the control group of Example 1 above. The piglets were separated into a control group fed with artificial milk for piglets, and reared for 3 weeks after weaning, and comparative tests were conducted on feeding intake and weight gain.

The results are shown in Table 2, as compared to the control group, the experimental area showed an approximately 38% increase in feed intake and approximately 27% increase in body weight gain.
'Increased.

Actual example 3 (feeding example for calves) A test plot in which 20 first-born calves were fed the semi-moist granular feed of the present invention with the following composition and a milk replacer for calves with the following composition, and a test plot with the same composition as above. A feeding test was conducted by dividing the animals into a control group in which they were fed calf milk replacer and calf artificial milk pellets having the composition shown below.

The results are shown in Table 3. Feeding of milk replacer for calves was discontinued in the test group at 28 days of age, and thereafter they showed good growth on semi-moist granular feed.

Next, the feed composition used in this example is described.

It was dissolved in 6 times as much warm water and administered.

In recent breeding of calves, calves are weaned at around 7 months of age and are fed a mixed feed called milk replacer for calves dissolved in warm water, as well as powdered feed or pellet feed called calf feed. However, milk replacer, which is usually dissolved in warm water, is fed until about 50 days old.

Feeding semi-moist granular feed, which is suitable for the taste of young animals of the present invention, instead of calf formula pellets increases intake and discontinues calf milk replacer within 30 days of age. I was able to do that.

Rolling example 4 (Example of feeding to experimental animals) Heated corn (expanded corn) 21% (W), skim milk powder 3
0% (W) casein 10% cane sugar 25% K propylene glycol 5% (W) soybean oil 4% W, vitamins, minerals and other 5% (W) powder mixture 100% (W),
22% (W) of water was added and kneaded and extrusion molded into a cylindrical shape with a diameter of about 1.2 cm and a length of about 2 cm, with a water content of 2.
Experimental rats and mice in the test area fed 2.5% (W) semi-moist grain feed were fed corn 24.5% (W).
5%, wheat flour 33% (W) skim milk powder 5% fused fish powder 10% (
W), soybean oil cake 17% (W) alfalfa meal 4%
(W), soybean oil 2.5% (W), vitamins, minerals and other 4% (W), water content approximately 8% m
The growth was much better than that of the experimental rats and mice in the control group, which were fed the conventional solid feed.

Furthermore, by adding an appropriate amount of vitamin C salt to the vitamins in the semi-humid granular feed composition of the present invention fed in the test area, it was extremely suitable for raising experimental monkeys.

The feed of the present invention used in Practical Example 1 was made from a starchy feed material that had been subjected to a swelling treatment, and the feed of the present invention used in Practical Rolling Example 3 was made from a starchy feed material that was not subjected to a swelling treatment. This is then mixed with other feed ingredients, kneaded with water, and molded, all of which are molded without heat molding.The feed of the present invention, for example, contains 27% corn ( W), sugar 20% (W), skim milk powder 30% (
W), soybean oil 15% (W) propylene glycol 1%
(W) and vitamins and other 7% (W) are mixed,
It is also possible to form porous feed by kneading water and subjecting it to swelling by heating and pressurizing it.

According to the present invention, the semi-moist granular feed of the present invention has better palatability for young animals than conventional powdered feed or pelleted feed for calves and piglets or for experiments, and Because it is soft, the feed intake is large, which not only speeds up growth, but it can also be fed during the lactation period, allowing earlier weaning time and improving breeding performance.

For example, piglets can be weaned when they are 3 to 5 days old. In addition, conventional powdered feed requires the labor of adding hot water or water to make it into a liquid, but the semi-moist granular feed of the present invention eliminates the above labor and is suitable for calves and This makes it extremely easy to raise a large number of piglets.

Furthermore, it is possible to significantly accelerate the weaning of rats, hamsters, and other laboratory animals, making it possible not only to conduct various experiments on these animals from a young age, but also to improve the breeding of these laboratory animals. It is possible to do so.

In addition, when molding this semi-humid granular feed without heat treatment, heat-labile vitamins, live bacteria, test drugs, etc. are directly mixed with other feed ingredients and molded. This can then be fed to experimental animals, making it extremely convenient for experiments.

Furthermore, a semi-moist granular feed with excellent shelf life was obtained.
