HU188503B - Process for the production of floating fodder for aquatic animals - Google Patents

Abstract

Feed for aquatic animals and snails is produced by mixing vegetable and animal proteins, vitamins and microelements, comminuting the mixt. to a particle size of 80-100 micrometer, adding water to form a paste with 10-80wt.% water content and forming the paste into sheets on a roller dryer.

Description

FIELD OF THE INVENTION The present invention relates to a process for the production of water-floating feed (hereinafter "feed") for aquarium and / or pond fish and / or snails with high protein and low fat and carbohydrate content.

The food is suitable for feeding water, it does not pollute the water, it does not change its redox potential, hardness, it is a floating substance easily accessible to fish.

In recent years, an increasing number of freshwater and / or ornamental fish farming activities have been undertaken. The fish feed used depends on the type of fish farmed, the nutritional requirements of the various dietary rays, but economic considerations are also gaining prominence.

It is known to perform procedures where, for example, powdered plants, skimmed milk powder, yeast, bran. employed. Dyen describes a solution eg. In Horn-Zsilinszky's "Aquaristics" (1970. Budapest).

Mention may also be made of Lányi's book, "Modern Aquaristics", where the author emphasizes the use of easily absorbable materials in the manufacture of artworks.

According to Hungarian Patent Application No. 163527, a nutrition and artificial medicine is produced which describes the benefits and the growth-promoting effects of the use of macroloid antibiotics.

It is an object of the present invention to provide a method for producing a thin plate feed that floats on water, floats, so is easily accessible to aquatic animals, does not contaminate water, and minimizes feeding losses. A further advantage of the process is that it also allows the incorporation of medicaments and the uniform distribution of the feed.

SUMMARY OF THE INVENTION Thus, the present invention provides a process for preparing water-floating feeds comprising mixing plant and animal proteins, eggs, vitamins, micro-macronutrients, and other additives, when necessary, with a grain size of 80-100 µm, slurrying the .

The thickness of the lumbar blue should be chosen within a maximum of 500 μπι.

The microscopic image of the feed so formed clearly shows the homogeneous distribution of the components and the mesh structure between which the floating particles adhere and keep the feed floating for a long period of time. It is preferred that the proteins used in the mixture be treated with enzymatic treatment, e.g. x-protease or amino peptidase enzymes.

Other additives include gelatin, carboxymethylcellulose, eggshell flour, viscone vitamins, micronutrients, agar.

In addition, various medicaments may be added to the mixture.

Preferably, the temperature of the surface of the sheet-to-plate roller dryer is between 90 ° C and 140 ° C.

The contact time and time required for contact with the hot surface is preferably 30 seconds.

In the case of medications containing vitamins, it is advisable to choose a lower temperature, but in this case it is advisable to extend the feeding time.

The comparative study has demonstrated the benefits of the process feed over the conventional feeding method.

The control flock received microflora for the first 10 days and then cut tubiflex. The experimental population was fed artificially throughout.

After four months, 70% of the experimental stock was 30% more advanced, 25% 15% more, and 5% 5% more advanced than the control fish.

The water in the aquarium remained clear and the fish color was more vivid than the control stock.

Mortality was 2% in the control and 1% in the experimental population.

The following are examples of steps to prepare the diet:

Example 1

Feed for juvenile fish:

Weigh for 100 kg of feed:

Corn flour 15.0 kg

Gelatin 5.0 kg

CMC 5.0 kg

Rice flour 10.0 kg

Extruded soybean meal 10.0 kg

Meat meal 62% 7.0 kg

Fish meal 20.0 kg

Super premixet 3.0 kg

Raw eggs 25.0 kg

The ingredients are chopped using a hammer grinder if necessary. The final particle size should be 80-100 µm.

The weighed materials are stirred and then suspended by the addition of water. The suspension is cca. It is adjusted to a dry matter content of 20% for uniform dispensing. It is preferred that the suspension be prepared in a heated state. This is suitably carried out at 40-70 ° C.

The slurry is then added to a hot roller, preferably at a temperature of 100-110 ° C, so that the slurry forms a uniformly thin film-like layer on the roll.

Contact time and time, eg. For 200 μτη film thickness, approx. 30 seconds.

The flakes from the roll are then cut as desired.

Example 2

Nutrition feed for juvenile ornamental fish:

Wheat flour 15.0 kg

Fish meal 15.0 kg

Gluten 18.0 kg

Gelatin 3.0 kg

CMC 3.0 kg

Eggshell flour 15.0 kg

Agar agar 2.9 kg

Superpremix 3.0 kg

Raw eggs 25.0 kg

Food coloring 0.1 kg

Otherwise, the procedure of Example 1 is followed.
