Abstract

PURPOSE:To produce excellent mineral mixed feed, by blending vegetable oil cake particularly linseed oil cake with minerals used as a nutriment for domestic animals and granulating the resultant blend. CONSTITUTION:A vegetable oil cake is used as a main raw material and particularly a residue obtained by pulverizing a residue after collecting linseed oil, etc., is preferably used. One or two or more minerals to be a nutriment for domestic animals are selected as those for blending in the vegetable oil cake. The optimum value of blending ratio of the vegetable oil cake with the minerals varied with the kinds thereof and method for granulation, but 2-45wt% vegetable oil cake based on the minerals is normally preferred. Either one of dry and wet methods may be used for the granulation. The resultant granular mineral mixed feed is a product, rich in general-purpose property and palatability and having improved granular characteristics, e.g. powdering ratio, pellet strength, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a granular mixed mineral feed, and more particularly to a mixed mineral feed containing vegetable oil cakes and having excellent granular characteristics.

BACKGROUND OF THE INVENTION When using minerals, which are important nutrients for livestock, as feed, several types of granulated minerals are known to improve feeding efficiency. For example, a representative example of this is the use of brown algae powder.
(see Japanese Patent Publication No. 60-55099) and granulated products using powders of leaves, stems, and leaves (see Japanese Patent Publication No. 60-55099). These products have been successful in improving certain grain characteristics and palatability.

The above feed is already manufactured industrially because it has a superior cooling effect compared to 9-granular feed, which is made by mixing powdered minerals with pond feed, or by granulating it using molasses or starch as an adhesive. is being carried out.

However, for example, the former method requires the coexistence of a certain amount of calcium as a mineral, and the latter method has the drawback that a feed exhibiting sufficient granular characteristics cannot be obtained unless an adhesive such as molasses is coexisted. Therefore, certain restrictions are imposed on the selection of feed types depending on the purpose of feeding the feed and the type of target livestock.

Therefore, the present inventors conducted repeated research to develop a more versatile granular mineral mixed feed, and found that although the granular mineral feed itself is already used as a component of mixed feed, etc., The present invention has been completed by discovering that it is possible to produce a granular mineral mixed feed with excellent versatility, palatability, and granular characteristics by using vegetable oil cake, which has not yet been used for granular purposes.

Therefore, the present invention provides a granular mineral mixed feed containing vegetable oil cake.

The vegetable oil cakes referred to in the present invention refer to oil residues extracted from flax seeds, soybeans, peanuts, vegetable crops, sesame seeds, etc. In particular, in order to achieve the effects of the present invention, they must be powdered. Nishi-tomo is preferably used.

All of these are used as single protein feeds, etc., and are known to be highly palatable to livestock; for example, using flaxseed oil cake has properties that improve bowel movements and regulate the intestines. However, from the viewpoint of the granular characteristics of the product of the present invention, linseed oil cake is preferable.

Mixed mineral feed refers to feed whose main ingredient is one or more minerals used as nutrients for livestock, such as calcium carbonate, calcium phosphate, sodium chloride, and magnesium carbonate. Depending on the type and purpose of feeding, other trace minerals and sweeteners such as saccharin, grass flavor, kelp powder, alfalfa (a legume grass), etc. may be added as appropriate to enhance palatability. can.

The optimum mixing ratio of vegetable oil cake in the granular mineral mixed feed of the present invention varies depending on the type of oil cake used, the type of mineral, and the granulation method, and is not critical. 2 to 45% by weight
It is preferable to include it.

Next, the granular mineral mixed feed of the present invention can be produced based on a granulation method that is known per se, and can be used regardless of whether it is a so-called dry granulation method or a wet granulation method. I can do it. For example, according to the dry granulation method, 5 to 10% by weight of water is added to a mixture of powders of minerals and vegetable oil cakes in an appropriate ratio, and if necessary, molasses, kelp powder, alfalfa, etc. After adding the accelerator, it can be molded using an extrusion pressurization type granulator such as a ring-type beretter or a desk-type pelleter.On the other hand, according to the wet granulation method, a mixture of minerals and vegetable oil cakes can be formed. After adding water to 12 to 20 wt. The product can be manufactured by granulating the product using a compression granulator such as a machine or an extruder, and then grading the granules using a sieving machine, followed by drying.

Functions and Effects The functions and effects of the granular mineral mixed feed of the invention will be clearly demonstrated by Examples and comparison with conventional products.

Example: tertiary calcium phosphate 3,100#, calcium carbonate 65
0g, mineral, premix (manufactured by Hokuren: Hokuren Mineral-M) 100. F and linseed oil cake 1,000
A mixture of 1I was prepared in advance and kneaded with 7t 25% molasses aqueous solution 1,00% ([') in a continuous kneader until it became a uniform ripple, and then it was thoroughly extruded using a pellet size die with a diameter of 5 mm. It was extruded into a cylindrical shape using a granulator.

Thereafter, the granulated material was further dried in a continuous fluidized bed dryer at 100°C for about 15 minutes to produce 5.1 kl of granular mineral feed.
I got it.

Particle characteristics (Measurement of Al powdering rate) The powdering rate was measured using a Stroup durability testing machine. After rotating the product samples soo and p at 50 rpm for 10 minutes, the powdering rate was measured using a sieve one step smaller than the pellet diameter (the current one). The test was conducted on a bottom-shaped product with a diameter of approximately 3-× length of 4 to 9ffiI+ with an opening of 2.3.
The grains were sized using an automatic sieve with 8 mesh meshes.

) and calculated as a percentage of the total amount that passed through the sieve.

(B) Measuring the strength of granules The strength of granules (pellets) is determined by converting the force (2) required to crush them in the diametrical direction into unit area force using a grain hardness measuring device available at a book store. kg/LM2).

Effect Granular mineral feeds having the compositions shown in the table below were prepared using the same method and on a scale similar to that of the above example.
The results of determining the grain characteristics are shown in the table.

As is clear from the table, the characteristics change depending on the composition other than vegetable oil cakes, but in general, if vegetable oil cakes are included at around 2 weight percent, the granular characteristics can be maintained even when mixed with minerals only. It is possible to provide a mineral feed having
