Description

GERMAN

The invention relates to a. Process for the production of a feed supplement, in particular for young animals, obtained from the rumen contents of slaughtered ruminants.

It is known per se that bites removed when ruminating healthy ruminants are stimulating and healing effects on sick animals by removing the microflora present in these bites causes a repopulation or change of mood of the stomach and intestinal flora of the sick animal.

On the other hand, it is also known to use the dried rumen contents of slaughtered animals as so-called Use rumen food. However, this rumen food does not have the good biological effects that mentioned fresh bites, because the hot drying of the Most of the microflora and active ingredients are destroyed and a gentle drying in a vacuum or by similar processes because of the large mass of substances to be dried, which are essentially consist only of fiber, is not economically feasible.

According to another well-known proposal, as a rearing agent for ruminating young animals from the Solid products of the rumen contents by pressing and centrifuging without using a Extracting agent a paste-like mass can be obtained, which is essentially from the existing Microorganisms exist, which by careful process measures are not in their viability be harmed.

It was previously assumed that the beneficial effect of the known supplementary feed obtained from the rumen content was due to the relatively high content of vitamin B _{12 present} .

Surprisingly, however, it has now been found that a product obtained from the rumen content according to the invention with a comparatively very low vitamin B ₁₂ content and a different composition is an extremely effective means of increasing the growth of young animals, the effect of this product being approximately that of the known Increase in growth by adding terramycin or other antibiotics.

According to the invention, such a product is made from the rumen contents of slaughtered ruminants Separation of its liquid and solid components obtained by after treatment with added extraction agents, the portions in solution are separated and the extraction solution is subjected to rapid drying.

According to the invention, the liquid extraction can be carried out at room temperature or also with moderately elevated processes

Temperature can be carried out by a number of different solvents.

Water has proven to be the simplest and cheapest solvent, but organic solvents, for example alcohol, in particular ethyl alcohol and dichloroethylene, and also a dichloroethylene emulsion, can be expediently used.
When using the various extraction agents, the amount of the active ingredients obtained fluctuates approximately within the limits of 1 to 2% of the dry substance, but the composition of the dried extracts is generally largely the same, as the corresponding protein determinations have shown with 55 to 60%,

The following amounts of B vitamins were determined in the dried extracts:

Vitamin B ₁ below 10 gamma / 1000 g

Vitamin B ₂ 2.3 mg / 1000 g

Vitamin B ₆ 0.9 mg / 1000 g

Pantothenic acid 12.0 mg / 1000 g

Nicotinic acid 16.7 mg / 1000 g

Vitamin B ₁₂ 50 gamma / 1000 g

The extracts are expediently separated off by filtration, centrifugation or other known methods Medium, and the gentle drying of the extracts can, for example, by vacuum, freezing or Spray drying can be carried out,

It has also proven to be useful to add the extraction liquid later than before drying Carrier for the active ingredients, if possible

add digestible materials, for example in the form of soluble or swellable substances, such as sugar, starch, dextrin, fat emulsion, mineral salt, etc., as well as mixtures of these substances. EXAMPLE 1 The rumen contents of a healthy, slaughtered cattle (about 50 kg mass) were mixed with 101 ethyl alcohol and stirred for 1 hour. The mass was then pressed out in a screw press and the pressed juice (about 301) was clarified using filter cloths. The dry matter analysis showed 1.48%. 9% dextrin was now dissolved in this pressed juice and this solution was subjected to spray drying. The dry concentrate is a light yellow, fine, very voluminous powder with a moisture content of 3 to 4% and a protein value of 5.43%. Example 2 Instead of the alcohol according to Example 1, dichloroethylene is used. Although dichloroethylene is not miscible with water, the rumen juice contains enough emulsifying substances to achieve a mixture. This mixture can be improved by adding appropriate emulsifiers. The extraction effect of dichloroethylene seems to be even stronger than that of alcohol, because the dry matter determination showed 2.0%. The press juice was dried in vacuo. Example 3 35 Instead of organic solvents, extraction can also be carried out with cold or warm water. The corresponding pressed juices contained 1.35% dry matter with cold extraction and 1.67% dry matter with warm extraction (about 70 ° C.). The pressed juice can be dried directly in the spray dryer. The result is a thorough, fine, very voluminous and slightly ammoniacal smelling powder that is strongly hygroscopic. The determination of protain was 56.2%. In practice, however, it is more expedient to add carrier substances for drying to the pressed juice, since the powders are then not so hygroscopic. Depending on the addition, concentrates with 4 to 7% protein result. The effect of the active ingredients according to the invention was determined, for example, in the following comparative tests: Comparative Aufzudhtversuche on three groups of Leghorn chickens, group I without addition (control group), group II with 0.05% addition of rumen extract and group III with 0.1% addition of rumen extract , resulted in: Average feed consumption weight per animal per kg weight after 8 weeks of gain 700 g4.50 kg660 g3.84 kg Group III 810 g3.56 kg In addition to a significant weight increase of around 16%, the addition of only 0.1% rumen extract to the feed resulted in a reduced feed consumption of around 20% compared to the normal group. Even with the addition of 0.05% rumen extract, a reduction in feed consumption with an approximately constant weight gain was already noticeable. The basic forage was of high quality and fully vitaminized, otherwise average growth weights of the control group of 700 g would not be possible. Further rearing experiments were carried out with rumen concentrates in which around 9% dextrin was added to the extraction fluid. After processing in the spray dryer, a dry concentrate with 4% crude protein resulted. 0.5% of this concentrate was added to a high-quality, fully vitaminized chick rearing feed with 19.3% crude protein and 1920 Cal, and the increase in growth was compared with the increase obtained by adding 10 g of terramycin. After 5 weeks, the average individual weight of terramycin groups was 437 g, rumen extract groups 424 g. There is therefore no difference to the known increase in growth due to the addition of terramycin. Further comparative rearing experiments were carried out with calves that were only raised with whole milk for the first 4 days and then with skimmed milk. Such rearing is hardly feasible without the addition of antibiotics. The addition of terramycin was therefore compared with that of rumen extract. The fattening period was 82 days and had the following results: initial weight final weight gain in 82 days average daily gain 1.40.2 kg117 kg76.8 kg936 g2.45.0 kg119 kg74.0 kg902 g3.41.0 kg115 kg74.0 kg • 902 g4.40, 0 kg115 kg75.0 kg915 g In the rearing of skimmed milk in calves, the rumen extract is equivalent to known antibiotic additives. The advantage over the antibiotics is the bio-natural form of the active ingredients of the rumen concentrate and its cheapness. Similar results were found, also in pig rearing experiments. 65 70 patent claims: 1.
