DE1692447C - Use of tree and rock lichens as an active ingredient in animal feed - Google Patents

Description

due to the dreaded poultry diseases. The situation is similar for large animals.

It has also been found that an addition of 0.01 to 1 percent by weight of lichen or lichen flour to a commercially available animal feed is sufficient to induce the described effect. This is surprising because, as already explained in detail above, the pure lichens are an inferior feed and such an effect was not to be expected due to the calorie or vitamin content of the lichens. It is clear that z. B. upon addition of 0.03 ⁰ Zo of a braiding flour is accelerated to a commercial feed, the growth of the animals without the need to be administered more calories in the form of feed. This fact shows that feeding the smallest amounts of lichen meal results in better utilization of the fodder.

Finally it was found that the lichen varieties Parmelia furfuraceae can be used for this purpose and Usnea barbata are particularly good. However, all other tree or rock lichens can also be used Are used insofar as they are lichen acids, which are likely to trigger the observed phenomena, contain. In order to achieve an even distribution of the active substances in the feed, it is advisable to finely grind the lichen and add the flour obtained in this way to the standard feed. In some cases, however, it is also possible to dispense with the mulling and the Use lichen in roughly cut form. The following examples are intended to illustrate the production of the Explain feed:

example 1

10 kg of »Usnea barbata« are carefully dried and with the addition of carbonated snow (Dry ice) finely ground. From the one so obtained 3 kg of flour is taken and this amount is mixed thoroughly with 10 t of a mixed chick rearing feed in flour form, produced according to the table of standards for compound feed. The finished one Food contains 0.03 Ί lichen meal. It has a clear one growth-increasing effect and increases the resistance of the animals to the occurrence of poultry! - diseases.

Example 2

10 kg of »Parmelia furfuraceae« are dried, finely cut and mixed with WO kg of pig fattening feed, produced according to the table of standards for compound feed, thoroughly mixed. Since so received Feed increases the animals' appetite, enables faster fattening and protects the animals Pre-existing illness.
