Process for the production of a feed for precious specialty animals as well as one according to this Process produced feed.

The invention relates to a method for production a feed for mustellids such as mink animals as well as for other fur-bearing small predators, and one after this Process produced feed.

The object on which the invention is based is to provide dry food for fur-bearing small predators, all of which are necessary for complete nutrition Contains components and as a result can replace the usual feed either partially or completely,

which consists of meatballs, fish and the like. Previous attempts to produce such a dry fodder were unsuccessful »After mixing the dry fodder with water, the putter mix must be of such a consistency that the animals can eat it without digestive difficulties at the same time it must be strong enough to prevent contamination of the animal fur. The risk of contamination arises as soon as the finished putter mixed with water is a little too liquid. As a result of the generally rather sticky nature of the putter, the furs in this case become practical through numerous Putter stains that cannot be removed are worthless. To such a thing To prevent pollution, the dry feed mixed with water must have a consistency that that it can be applied to the wire mesh of the cages without falling through.

The dry fodder must therefore be able to soak up a sufficient amount of water, since putter that is too dry, floury or crumbly is only poorly accepted and, on the contrary, is dragged around. Such a putter is therefore the primary cause of disturbances in growth, fur formation, reproduction and other physiological functions, and also very often results in considerable mortality. As is well known from practice, fur-bearing predators react very strongly to an exact putter composition with the right taste and consistency.3 _e

Furthermore, the feed must be highly concentrated and one have a high fat content. Since a high fat content is contrary to the requirement that the feed have a must include sufficient information. touched previous Do not try to get satisfactory results.

It was found, however, that through a suitable composition and the manner of production easily a food for Mustelüden and others can produce small predators, which can be immediately removed from the animals after mixing with water without disadvantageous Polgen can be included.

According to the method according to the invention, at least 15% by weight of molten fat containing an emulsifier with several other air-dry fat, not more than 30 Weight ^ water-soluble and at least 15 weight ^ Decomposed starchy components swellable in water containing substances mixed, whereupon this mixture after its solidification to a hard mass in a loose, crumbly mixture is crushed, which contains at least 15% crude fat by weight, at least 25% by weight Crude proteins, not more than 5% by weight of crude cellulose, not more than 52.5% by weight of other carbohydrates, not more than 10% by weight Ash and a maximum of 12.5% moisture by weight, the percentages being based on the total weight of the air-dry Related to the product.

Preferably, said mixture of 30-65% animal proteins with more than 60 % crude protein, 4-15 % vegetable proteins with more than 40 % crude protein, 15-35% decomposed starchy substances, 1-5% of a mineral, vitamins and the like is used Mixtures containing additives and 15-25 % fat containing an emulsifier are produced.

The feed produced on this catfish can absorb an amount of water of at least 50 % of its weight without dissolving in water. The mixed with water

209817/0160

Trockenfutf ^ r has a tough, dough-like consistency and can be placed on the cages within reach of the animals without dripping through, so that the Do not touch the putter immediately with their furs can. The air-dry feed can at least Store for J5 months without any loss of quality, so no Special systems such as cooling machines and the like are required for this purpose on the fur farm. When putting mink animals with this putter remains growth, port plantability and others physiological punctures normal, so one definitely satisfactory fur formation is achieved, it should be particularly pointed out that with Water-mixed dry feed according to the invention from was gladly accepted by the mink.

To produce the air-dry putter, the liquid fat, to which one or more emulsifiers have been added, is mixed with the other ingredients, which have been previously ground and / or mixed with one another as required. This mixture is homogenized and cooled to a rigid hard mass. This hard mass is finally crushed into a grain of loose, crumbly form, which can easily absorb an amount of water of at least 50% of its weight or even more without losing its tough, dough-like consistency.

A detailed explanation of the invention follows from the following examples:

209817/0160

Example I.

In a suitable mixer, the substances listed below were mixed with one another after they, as far as this was necessary had been ground.

Animal proteins 5 kg blood meal

20 kg of meat meal

20 kg of skimmed milk powder

Animal protein product 10 kg dry yeast Decomposed starchy

Vitamins, minerals and other micronutrients based on flour.

25 kg of stabilized pork fat were mixed with 1.5 kg of lecithin as an emulsifier and melted with the aforementioned Mixture homogenized so that a mass with a total weight of 100 kg resulted. The finished hot and soft The mixture was stored in a porous pack until the fat had completely solidified and became a hard mass Form of some lump had emerged.

This hard mass was crushed in a crushing machine to form granules, the individual crumbs of which become one Had a maximum diameter of 1 cm, whereupon the finished granulate was packed in moisture-proof bags. the The solidification time of the fat can be reduced by artificial cooling accelerate, whereby this cooling process can be combined with the granulation under certain circumstances

209817/0160

The finished granules could be at least 50 # of its weight absorb in water. This watered putter had a chewy, dough-like consistency and was used by the mink animals eaten with pleasure. The granules could be stored in the moisture-proof packaging for at least 3 months.

The finished granulate could be stored in a moisture-proof pack for at least 3 months and absorbed at least 50 % of its own weight in water, resulting in a tough, dough-like lining.

Example y

Reproduction experiments were carried out on a large number of mink animals in various countries, with pearls, sapphires and pastel breeds being examined in addition to the standard breed. In these experiments, 48 animals were fed 100% with the water-mixed feed according to the invention, 4-9 animals 50-80% with the water-mixed feed according to the invention and the remainder with so-called fern feed, while 1077 animals were used as control animals were fed only with fern feed. Farm feed is usually understood to be a mixture that is produced by the breeder himself and consists of around 40% fish and fish waste, and 25 % chicken.

The table shows that the putter according to the invention no harmful influence on port planting ability the mink animals, so that it can replace the usual farm fodder in any desired amount, as far as port planting is thought.

During these experiments, a number of the animals were also switched from a diet with parm food to a diet with 100 % watered putter according to the invention, at a point in time which was normally considered extremely unfavorable by the breeders. 5 sapphires and 6 pearls were switched in this way about 6 weeks before the mating season and 20 pearls immediately after the mating season. The following results were obtained:

For this purpose, the quality of the fur was matched to a standard quality that corresponds to the genetic make-up of the animals compared, since an animal can never produce a better fur than its genetic make-up corresponds to, one however, poor fur can develop under unfavorable circumstances *

The quality of a fur cannot be determined exactly because it depends on many factors. With the ones up for debate here tests, the animals were assessed by an independent expert, who estimated values from 1-5 for the Extent, the undercoat, the outer hair (i.e. the smooth upper hair as opposed to the frizzy undercoat) and for the color gave. It is pointed out in this connection that the weight of the animals does not necessarily relate to the extent of the Fur matches and significant fluctuations throughout is subject to the fur formation period, since it depends mainly on the condition of the animals. Because of this, the weight became of the animals are not included in the table of estimates below.

From the average estimates in the table above it is found that the putter according to the invention is not harmful in any way Influence on the quality of the fur. In contrast the fur quality when the animals are fed with the putter according to the invention is easily equivalent to the fur quality, which was achieved in animals with the usual Farm fodder was fed.

In summary, therefore, it should be noted that the feed according to the invention meets all the requirements that the Physiological punctures of the mink animals are made and are in the interests of the breeders.
