Description

[Detailed description of the invention] [Technical field] The present invention relates to granular feed for young animals.

[Prior Art] Conventionally, artificial feeds for young animals include, for example, wheat flour, soybean flour,
Corn, skim milk powder, sugars such as sucrose and glucose,
It is manufactured using fishmeal, oil, etc. as the main raw materials. When such feed is fed in powder form, it is difficult to ingest due to the looseness of the feed, which makes it less palatable to animals, and when fed in a feeder, it has poor fluidity and runs onto the feeding surface. The problem was that it didn't work.

For this reason, it has been proposed to make the feed into pellets, in which starchy materials, blackstrap molasses, dried alcoholic fermentation waste liquid, etc. are used as a binder for solidification, and the feed is formed into pellets. However, the disadvantage is that the pellet-shaped feed is hard and does not suit the taste of animals. In that case, if you try to manufacture soft pellets using similar materials, there will be a lot of loss in the manufacturing process, resulting in a poor product yield, and the drawback is that the pellets will crumble into powder during transportation. be.

In addition, for the purpose of soft feed, the moisture content is increased from 20 to 20%.
Semi-moist feeds containing 50% by weight are also known, but they complicate packaging for transport, handling and feeding methods.

Furthermore, for the purpose of improving fluidity and palatability, a granular feed for piglets has recently been developed in which more than 50% of the granules have a particle size of 0-25m1IQ or more and an angle of repose of 45 degrees or less. (Japanese Unexamined Patent Publication No. 173545/1983). However, in this granular feed for piglets, more than 50% of the granules have a particle size of 0.
．． 25~0,5+am, and particle size 0.5
The proportion of granules larger than mm is about 36% or less, which means that the particle size is small and the palatability of piglets is not sufficient.

Therefore, from the above points, there has been a demand for a feed that has better palatability, is rich in fluidity, and is easy to handle.

[Contents of the invention] The present inventors have continued research on animal feed.

As a result, it was found that if the feed given to young animals is made into granules with a specific particle size range, the intake amount will be more palatable to the young animals and lead to greater weight gain.Furthermore, the granular feed is highly fluid and easy to handle. The present invention was completed based on the discovery that it is easy.

That is, in the present invention, the particle size is 1.68 mm or more and 3.36 mm.
This is a granular feed for young animals, characterized in that the content of granules in the range of less than mm is 50% by weight or more.

As mentioned above, in the granular feed for young animals of the present invention, the content of granules having a particle size in the range of 1.6801111 or more and less than 3.3611II11 is 50% or more based on the weight of the entire granular feed. The lower the content of granules in this size range, the lower the palatability by young animals.

In terms of palatability and weight gain by young animals,
It is preferable that the content of granules in the particle size range of 1.68 mm or more and less than 36 mm is about 70% by weight or more. Further, within the particle size range of 1.68 mm or more and less than 3.36 mm, particles with a particle size of 1, 68 mm or more and 2,38 I
It is preferable that the content of granules in the range of less than II11 is about 70% by weight or more, especially about 80 to 100% by weight of the whole granular feed, because it is extremely palatable to young animals.
This is followed by a particle size of 2.38+++m or more and 3.36mm.
The content of granules in the range of less than about 8% of the total granular feed
0 to 100% by weight has good palatability. The more uniform the particle size of the granules, the more palatability tends to improve.

The granular feed of the present invention includes wheat flour, soybean flour, soybean oil meal, corn flour, barley flour, skim milk powder, fish meal, sugars, whey bran, rice bran, milo flour, alfalfa meal, linseed oil meal, oils and fats, yeast, minerals, vitamins, salt,
It can be produced by combining any of the raw materials conventionally used in this type of feed, such as flavorings and amino acids, and granulating it into granules, in which case thickeners such as guar gum and CMC can be used. promotes the formation of large granules.

If a granular feed containing approximately 50% by weight or more of granules having a particle size defined in the present invention of 1.68 mm or more and less than 3.36 mm cannot be directly obtained by granulation, It is preferable to classify the produced granules using a sieve edge or other method so that the content of the granules with a size of 1-68 mm or more and less than 3.36 n+m is about 50% by weight or more of the entire granular feed. .

Any granulation method, granulation device, etc. can be used as long as it can provide granular feed having a particle size within the scope of the present invention.
Granulation conditions can also be adopted.

For example, the granular feed of the present invention can be produced by a stirring granulation method, a fluidized granulation method, an extrusion granulation method, etc. Among them, the stirring granulation method is used when the grain size is 1.68 mm or more.
This method is preferable because it can provide granules with a large content of granules less than +, produces granules with low hardness, and has high productivity.

Depending on the composition of feed for young animals, it may be difficult to form granules, particularly into granules with a relatively large particle size of 1.68 mm or more. In that case, sugars, which are often added to feed to increase palatability by young animals, are mixed in advance with water or other liquid materials to form a liquid, and then added to the remaining materials for granulation. Compared to the case of directly mixing and granulating powdered saccharide and other material 1, it becomes easier to granulate the granules, and the content ratio of granules with a large particle size can be increased. When blending sugars in liquid form, it is recommended to dissolve them in water and add them at the time of granulation to achieve high granulation properties and soft texture. Granules can be obtained, and by dissolving the two substances, caster sugar and glucose, in water, force a is applied during granulation.
The granulation properties will be even better if the temperature is increased. However, instead of caster sugar, other sugars such as granulated sugar, brown sugar, glucose, brown sugar, and granulated sugar may be dissolved in water together with glucose or liquid sugar and added during granulation. may be used.

It is desirable to carry out the granulation operation by adding about 12 to 25% by weight of water on the outside in terms of granulation properties and the hardness of the resulting granular feed.

Furthermore, the granular feed of the present invention typically has a hardness of about 5 kg/am' or less when measured by the method described below, and a water content of about 6 to 15% by weight. It is preferable in terms of palatability, ease of handling the feed, etc.

[Method for measuring hardness of granular feed] Fill a cylinder with an inner diameter of 1.05 cm and a depth of 7.5 cm with granular feed without applying pressure until it is completely ground. A load of 5 kg is applied from above to this using a rheometer: NRM-2005J (manufactured by Fudo Kogyo Co., Ltd.).

The space volume A (cm') inside the cylinder created when a load of 5 kg was applied was measured, and the hardness was determined using the following formula.

[Method for Measuring Moisture Content of Granular Feed] 5 g of granular feed was collected and dried at 110° C. for 2 hours, and the weight of the feed (a) was measured and calculated using the following formula.

The composition of the granular feed of the present invention is not particularly limited, and any conventionally known composition can be employed in the present invention depending on the type, condition, body weight, etc. of the animal.

The term "young animal" as used in the present invention refers to an animal such as a pig, cow, horse, cow, goat, dog, cat, monkey, rat, mouse, etc., which has not yet grown up. This refers to animals up to about 6 months of age, and in the case of pigs, it usually refers to animals up to about 2 months of age, but this is only a rough guide and is limited to this as it varies depending on the type, breed, and individual of the animal. It's not a thing. Among the above-mentioned animals, the granular feed of the present invention is particularly suitable for young veterinary animals such as pigs, cows, dogs, and cats.

[Effects of the Invention] In the present invention, the feed for young animals is made into a granular feed in which the content of ungrooved granules with a particle size of 1.68 mm or more and 3.36+ nm is 5011% or more. Palatability is greatly improved, feed intake is greatly increased, and good weight gain can be achieved.

Moreover, the granular feed of the present invention has low hardness and is soft, yet has high fluidity and is easy to handle.

Next, the present invention will be specifically explained by giving examples, but the present invention is not limited by these examples.
