It is known in agriculture to add a mineral, for example in the form of a "mixture of minerals" or a "mixture of minerals and vitamins", to domestic animal feed. However, conventional mixtures are not always the best possible in terms of the composition of their macro-elements such as calcium and magnesium, and their mineral spectrum is not particularly broad in terms of micro-elements (trace elements).

The lack of a sufficiently broad spectrum of minerals in animal feed seems to be a serious problem. For example, the book "Trace Elements in Human and Animal Nutrition" (3rd Edition, EJ Underwood, Academic Press, New York and London) states that enzyme activity and therefore 56613 also metabolism and vital functions depend on the presence of mineral elements, it can be stated that there are many trace element-dependent, metabolic enzymes that have yet to be discovered.

Earl Frieden's paper (Scient. Am. 1972; 227, 52-60) shows that more chemical elements than previously thought are essential for vital functions, either in macro or micro amounts. From this paper it can be concluded that the presence of chemical elements affects, to a certain extent even decisively, the conditions of life. The fact that some trace elements are only needed in very small quantities does not in any way diminish their importance.

Unfortunately, the intensive use of cultivated areas during the industrialized era has, as a consequence, resulted in the plants depleting the soil of many of the elements previously present in the soil, resulting in a high shortage of such elements in the soil of certain areas. In addition, modern fertilization methods result in the use of further processed fertilizers on arable land. Fertilizers are produced in an increasingly compact and cleaner form, which can thus reduce, for example, transport costs. One consequence of this is that the broad spectrum of minerals, which was not given much attention in the past, is now lacking, so that such modern fertilizers do not effectively compensate for the removal of minerals caused by plants. It can therefore be assumed that plants or parts of plants produced in intensive farming and used for animal feed often have a narrower mineral spectrum than similar plants or parts of plants grown in areas where the minerals have not yet been substantially depleted.

Animal feed with a low mineral spectrum cannot supply animals with all the minerals and trace elements that are in fact necessary for the best possible development of the animals, whether these elements have already been identified or have not yet been identified as important or beneficial, and this deficiency cannot be fully compensated by conventional mineral mixtures in the context of feed.

56613

The elemental content of animal feed can be increased by mixing fly ash, which is a waste product with a broad spectrum of elements.

The terms "broad-spectrum" and "rich-spectrum" in this specification mean that the substance in question contains a large number of elements and in particular a broad spectrum of trace elements.

In this description and in the appended claims, fly ash means a waste product which is formed, for example, in power plants which use finely ground anthracite, e.g. a particle size of 0-1 mm, as fuel. As these particles burn, ash particles, usually between 0 and 100 microns in size, remain. These fly ash-forming particles are collected in electrostatic precipitators, from which the particles are usually removed by pumping with air and collected in closed tanks. The particles are fluid and can be pumped as cement particles and stored in tanks or silos.The volumetric weight of such fly ash is usually approx.

0.7 tons / m 2, but vibrating the ash causes its volume weight to increase to about 1.1 tons / m 2. Dry fly ash can be transported in closed tanks or containers, such as trucks or ships, as well as cement. From tanks, silos or other closed tanks, fly ash can be removed either by pumping with air, as mentioned above, or by hydraulic transfer. When the fly ash is hydraulically transferred or otherwise thoroughly moistened, the volume weight of the product obtained, i.e. the wet fly ash, is about 1-1.8 tons / m 2, usually 1.4 tons / m 2.

Fly ash, like the fuel from which it is formed, comprises a very rich spectrum of elements, including a very large number of trace elements, as will be described in more detail below. In addition, the spectrum of elements in the fuel, which therefore, although modified in 1000 ° C combustion, also occurs in fly ash, must necessarily be consistent with the elemental spectrum of plants that essentially formed fossil fuels hundreds of millions of years ago.

An example of a fly ash used according to the principles of the present invention is fly ash obtained by burning German coal and having the following weight ratios of value elements: 4

Mn 0.11, Ba 0.09, Sr 0.04, Cr 0.05, V 0.04, Zr 0.03, Rb 0.02, Cl 0.01. Cu and Se are also present in this fly ash in weight ratios of the same order of magnitude as other trace elements.

The elemental ratios of fly ash from other types of carbon may be somewhat different from those described above, but all such ashes always cover a wide range of value elements. Thus, for example, ash from another German carbon sample and ash from a single Polish carbon sample showed the following elemental weight ratios, respectively: B 1,600 600

With more advanced analytical methods, the sensitivity limit is lowered, and the abundance of elements in the spectrum can be determined more accurately. Thus, Spark Source MS, 36, January / February 1973 gives the following typical trace element analysis result for fly ash, in which concentrations are expressed in ppm (by weight): 5 56613

It is known that fly ash can be added to animal feed. Leri ash is then added directly to the feed and the amounts used have varied between 0.5 and 5% by weight. The most preferred amounts have been about 2% by weight in summer time and about 1.5% by weight in winter time.

According to the present invention, fly ash is not administered as such to animals, but in a preparation containing fly ash in combination with readily soluble, physiologically acceptable salts of alkali metals and / or alkaline earth metals. In this way, a versatile, easy-to-feed preparation is obtained which not only contains fly ash with a broad mineral spectrum, but also contains alkali metals and / or alkaline earth metals and possibly other ingredients to form a useful and inexpensive animal feed additive, so that the preparation can be considered a complete additive supplying macro- and micro-elements to animal feed which replaces or supplements known compound mineral mixtures and which is more advantageous to use than fly ash alone.

The invention therefore relates to a preparation for addition to animal feed, characterized in that it contains, as its main constituents, readily soluble, physiologically acceptable alkali metal and / or alkaline earth metal salts and about 1 to 20% by weight of fly ash from power plants heated with hard pulverized coal. to be added to the feed to such an extent that the final feed contains 0,0003 to 0,1% by weight of fly ash.

The preparation according to the invention is mixed into the feed so that the feed fed to small animals, e.g. chickens for slaughter, contains 0.005-0.1% by weight, preferably 0.01-0.06% by weight of grove ash. For feed intended for medium-sized animals, e.g. pigs for slaughter, the preparation is added so that the feed contains 0.0015-0.025 wt.%, Preferably 0.0025-0.015 wt.% Of fly ash, which feed is typically administered at about 2 kg per day to an animal having a body weight of about 50 kg. For feed intended for large animals, e.g. cows and horses, the preparation is added so that the feed contains 0.0003-0.006 wt.%, Preferably 0.0006-0.004 wt.% Of fly ash, which feed is typically administered at about 4 kg per day to an animal which body weight is about 600 kg.

The preparation according to the invention preferably contains salts of calcium, potassium and magnesium and possibly also sodium. If desired, other metal salts may be added, the presence of which in greater amounts than that obtained from fly ash is preferred, such as zinc salt, manganese salt, iron salt, copper salt, cobalt salt, etc. Vitamins may also be added if desired.

7 56613

The preparations according to the invention contain about 20 to 100, suitably about 30 to 70 and most preferably about 60 g of calcium per kg of preparation. Magnesium is suitably about 3 to 20, more preferably about 5 to 10 g per kilogram of preparation. The potassium is about 50-200, suitably about 70-150 and most preferably about 110-125 g per kg of preparation. When sodium is present, it may be e.g. I-30 g per kg of preparation, but it is often preferred to keep the sodium content low, e.g. about 1-5 g per kg of preparation, or sodium may be completely omitted from the main ingredients of the preparation.

In the preparation according to the invention, the alkali and / or alkaline earth metal salts must be physiologically acceptable, easily dissociable or soluble and, preferably, substantially neutral.

Gluconate, citrate, lactate, glycerophosphate, tartrate and hydrogen phosphate anions are examples of anions which, together with the above metals, form salts which are suitable as ingredients in the preparations according to the invention. It is contemplated that the salts of calcium, magnesium and potassium, and sodium, if present, are salts that readily dissociate, rapidly releasing the metal ions in question, and disodium monohydrogen phosphate, calcium gluconate, calcium lactate, calcium citrate, magnesium phosphate, magnesium phosphate, magnesium carbonate are all examples of easily dissociable salts which are at the same time physiologically acceptable, so that these salts are well suited for use in the invention.

The preparation according to the invention contains fly ash of about 1 to 20% by weight, suitably 5 to 12% by weight # and most preferably 7 to 10% by weight, for example 8% by weight, based on the total weight of the mixture as dry fly ash.

The preparation according to the invention is suitably in the form of a powder, in which form it can be easily handled and administered to animals or mixed with other feed ingredients or their additives. However, the preparation according to the invention can also be prepared in granulated form using conventional granulating media, such as, for example, wheat starch.

However, the preparation according to the invention is preferably mixed with the usual feed ration in the same manner as when mixing with a conventional ready-mix. The amount of preparation according to the invention to be added to a normal feed depends on the amount of feed the animal eats per day and the weight of the animal.

The preparation administered directly to the animal or added to the feed or compound mixture should preferably contain enough fly ash to provide the above amounts of fly ash per kilogram of body weight per day, i.e. that in the case of a preparation according to the invention containing 8% fly ash. Recommended doses for small animals, e.g. poultry as for chickens are about 1-300, suitably 60-200 and most preferably 125-175 mg of preparation per kilogram of body weight per day. For medium-sized animals, e.g. pigs, the recommended doses are 1-150, suitably about 10-100 and most preferably about 20-80 mg of the preparation per kilogram of body weight per day. For large animals, e.g. cows and horses, the recommended amounts are about 1-100, suitably 2-50 and most preferably about 5-20 mg of the preparation per kilogram of body weight per day. It is clear that if the fly ash content of the preparation deviates from 8 #, the daily amount of preparation will be adjusted accordingly.

When the fly ash-containing preparation is administered as a feed additive, it is mixed with, for example, 0.1-1, preferably 0.2-0.5% by weight of feed for small animals, e.g. chickens for slaughter. For feed fed to medium-sized animals, e.g. pigs for slaughter, a preparation of 0.025-0.25, preferably 0.05-0.13% by weight, is added, such feed being fed to an animal weighing about 50 kg, typically about 2 kg per day. To the feed fed to large animals, e.g. cows and horses, the preparation is suitably added to about 0.006-0.06, preferably 0.013-0.03 wt.%, Such feed being given to an animal weighing about 600 kg n.

4 kg per day.

In addition to the above-mentioned advantage that the preparation according to the invention can provide a more complete mineral addition than fly ash alone, the preparation according to the invention has the advantage that fly ash can be administered to animals more precisely and in a more controlled manner, as fly ash is diluted in the mixture. When administering fly ash as such to animals, care should be taken to avoid overdosing (to avoid possible adverse effects due to excessive amounts of inorganic salts and oxides in fly ash) and underdosing (to avoid losing the beneficial effect of use 56613 9), and it is of course advantageous to and reproducible as possible. The problems of accurate and reproducible dosing of the desired amounts of fly ash are reduced when using the preparation according to the invention. This advantage in terms of dosage is, of course, also achieved when the fly ash according to an embodiment of the present invention is diluted with any other physiologically acceptable carrier or diluent or mixture of carriers or diluents, but the preparation of the above invention containing alkali and / or alkaline earth metal salts is considered the special advantages referred to above.

The preparation according to the invention can be made by mixing fly ash and alkali and / or alkaline earth metal salts with any other smaller amounts of additives, and granulating the mixture if desired. The fly ash is preferably incorporated into the preparation in dry form, and all amounts by weight of fly ash reported in this specification are based on its dry form.

The invention is further illustrated by the following examples:

Dairy cows

An experiment in cows was performed to determine the extent to which milk production in dairy cows could be maintained by reducing the protein content of the feed. The experiment was performed on 10 cows, 3 of which calved during the experiment, while the other cows were pregnant. The cows were given 3.5 kg of concentrate instead of the normal 7.0 kg of concentrate, otherwise in conjunction with conventional feeding. During the experiment, in which the cows were fed only half of the normal amount of concentrate, each cow was given 6 g per day of the preparation corresponding to the preparation of Example 2. It was found that the milk production capacity of dairy cows was maintained despite halving the feed ration.

In addition, the following comparative experiments were performed.

C.

The young pigs for slaughter were fed, on the one hand, normal feed, "extra", which contained the usual minerals to be given to pigs and 190 ppm copper, and, on the other hand, a similar standard feed to which 175 g of the preparation according to the invention was added. The results are shown in the following table: / 56613 17
