Description

Description: TECHNICAL FIELD The present invention relates to a granular mixed feed containing minerals as a main component, and more particularly, it mainly relates to minerals containing linseed oil residue and having excellent granular properties and the like. The present invention relates to a granular mixed feed as an ingredient (hereinafter referred to as a granular mineral mixed feed).

2. Description of the Related Art When using minerals, which are important as nutrients for livestock, as feed, some of them have been granulated in order to enhance the feeding effect. For example, typical examples thereof include those using powder of brown algae (see Japanese Patent Publication No. 58-35066), and those granulated using powders of leaf stems and leaves (Japanese Patent Publication No. 6-56). -55099 gazette). These have succeeded in improving certain granular characteristics and palatability.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The above feed has excellent effects as compared with those obtained by mixing powdered minerals with other feeds and powdered feed granulated using molasses or starch as an adhesive. Since it plays, it has already been industrially manufactured.

However, for example, the former requires a certain amount of calcium as a mineral to coexist, and the latter has a drawback that a feed showing sufficient powdery characteristics cannot be obtained unless an adhesive such as molasses is allowed to coexist. . Therefore, certain restrictions were imposed on the selection of feed composition according to the purpose of feeding feed and the type of target livestock.

Therefore, as a result of repeated research to develop a more versatile granular mineral mixed feed, the present inventors themselves may already be used as a component of a compounded feed or the like. It was found that a linseed oil residue, which is unknown to be used for the purpose of granules, can be used to produce a granular mineral-mixed feed excellent in versatility, palatability and granular characteristics, and completed the present invention.

Means for Solving the Problems Accordingly, the present invention provides a granular mineral mixed feed containing linseed oil dregs.

The linseed oil residue according to the present invention refers to a residue obtained by collecting oil from flax seeds, and in particular, in order to obtain the effects of the present invention, powdered ones thereof are preferably used.

Further, the mineral-mixed feed, calcium carbonate, calcium phosphate, sodium chloride, refers to a feed mainly containing one or more selected from minerals used as nutrients for livestock such as magnesium carbonate, the type of feeding animals, Depending on the purpose of feeding, other trace minerals and sweeteners such as molasses, saccharin, grass flavor, konbu powder, alfalfa (legume grass) and the like can be added as appropriate in order to enhance palatability.

In addition, the mixing ratio of the linseed oil residue in the granular mineral mixed feed of the present invention is not critical because the optimum value differs depending on the type of minerals used and the granulation method, but it is generally preferable to contain 2 to 45% by weight. is there.

Next, the granular and mineral mixed feed of the present invention can be produced based on a granulation method known per se, and is used regardless of whether it is a so-called dry granulation method or a wet granulation method. be able to. For example, according to the dry granulation method, 5 to 10% by weight of water is added to a mixture of minerals and linseed oil meal powder at an appropriate ratio, and if necessary, molasses, kelp powder, alfalfa, etc. After the addition, the mixture may be molded by an extrusion pressure type granulator such as a ring type pelletizer or a desk type pelleter. On the other hand, according to the wet granulation method, water is contained in a mixture of minerals and linseed oil residue in an amount of 12 to 20% by weight,
If necessary, the same preference promoting substance as described above is added, and then the mixture is kneaded, and the kneaded product is granulated as it is by an extrusion granulator such as a twin screw or a vacuum, or a compression granulator such as an extruder, and further granulated. The product can be manufactured by sizing with a machine and then drying.

Action / Effect Hereinafter, the action / effect of the granular mineral-mixed feed of the present invention will be clarified by comparison with Examples and conventional products.

Example 3,100 g of tricalcium phosphate, 650 g of calcium carbonate, mineral premix (made by Hokuren: Hokuren Minerals-
M) A mixture of 100 g and linseed oil cake 1,000 g was kneaded with a previously prepared 25% molasses aqueous solution 1,000 g by a continuous kneader until a uniform gel was formed, and then the pellet size diameter
It was extruded into a columnar shape by an extrusion granulator equipped with a 5 mm die. After that, the granulated product is further dried at 100 ° C for 15 minutes in a continuous fluidized bed dryer to obtain 5.1 kg of granular mineral feed.

Granularity (A) Measurement of pulverization rate The pulverization rate was measured using a Stroup durability tester.
After rotating 500g of the product sample at 50rpm for 10 minutes, the sieve is one step smaller than the pellet diameter (in this test, a molded product with a diameter of about 3mm and a length of 4 to 9mm is automatically sieved with 2.38mm (8 mesh) meshes. The particles were sized, and the percentage was calculated as a percentage of the total amount passed through the sieve.

(B) Measurement of granular material strength Granular material (pellet) strength is measured by a Kiya-type shell-grain hardness tester by converting the force (kg) required for crushing in the diametrical direction per unit area and breaking pressure (kg / cm ² ).

Effects Granular mineral feeds each having the composition shown in the following table were prepared by a similar method on an almost same scale as the above example,
The results obtained for the granular characteristics are shown in the table.

As is clear from the table, the characteristics change depending on the composition other than the linseed oil residue, but in general, if the linseed oil residue is contained at around 2% by weight, a mineral feed having a quasi granular property even when mixed with minerals only is used. Can be provided.

Claims (2)

[Claims] 1. A granular feed containing minerals as a main component and flaxseed meal. 2. The granular feed according to claim 1, which contains 2-45% by weight of flaxseed meal.
