Abstract

The invention removes existing manufacturing practice biofactor supplements in their solid state monitoring their storage only so that they can later be applied in feed mixtures or additives thereof. According to the invention, it is preferable to produce a optionally store premixes of these supplements biofactors by spraying their solutions into organic feed ingredients, especially for their fluid state, thereby achieving perfect very small proportions of these supplements and ensure perfect homogeneity of such premixes, which are then easier to mix with other feed ingredients.

Description

The invention relates to a method of applying biofactor supplements for animal feed purposes.

To date, efforts to better and more efficiently utilize the nutritional and health status of animals affecting feed values have led, inter alia, to the administration of biotechnological products, particularly amino acids, vitamins, hormones, enzymes, growth promoters and antioxidants, obtained from solutions by crystallization, precipitation, drying or other operations such as solid and loose matter. However, the preparations thus obtained are too concentrated for use in agricultural practice and are therefore diluted in the plants of the pharmaceutical industry still producing them with the appropriate components to concentrations useful in the manufacture of compound feed.

a frequent disadvantage of these preparations is, for example, their unsuitable physical properties and the resulting poor homogeneity of the feed mixtures into which they are mixed. For example, it is known that in the production of lysine by drying this amino acid in a spray drier, a powdered product is obtained which, however, solidifies after a few days, so that it must be reprocessed before further processing. This, however, no longer achieves perfect homogeneity of the feed mixture produced from the treated composition and other feed components.

»

Thus, the current technology for producing such biofactor supplements produces, in the first production phase, pulverulent materials of often unsuitable physical properties which are mixed with the feed components only after their post-treatment, and it is never possible to ensure their even distribution in the complete feed mixture.

The disadvantage of the current state of application of such biofactor supplements is therefore that they first precipitate, extract, dry etc. from the liquid state, which means expending energies of different kinds just to be stored for future use in feed, often changing their physical properties requiring energy re-use and labor to be restored to the condition that they are useful as biofactor supplements in cattle feed.

These disadvantages are overcome by the fact that biofactor supplements such as amino acids, hormones, vitamins, enzymes, growth promoters, antioxidants and the like are added to the feed components of organic origin, for example, cereal meal, feed or soy flour or bran as well as / or into its components of inorganic origin, such as bentonite, zeolites, limestone and the like, applied in the form of solutions which are sprayed on at least one feed component in amounts and concentrations moisturizing it to a moisture value of up to 40% by weight with respect to the applied biofactor supplements. ensuring, after its possible drying, their required share in the complete feed mixture. It is also essential to the invention that the injection of biofactor supplements. the feed components are carried out after they have been brought into the fluidized state. .

r

Advantages and progress of this method of application of biofactor supplements to the compound feed or its components can be seen in the fact that it excludes operations leading to a storable form of these.

of biofactor supplements and replacing them by obtaining a premixture of these substances with any of the feed ingredients suitable for storage for later use for the purchase of feed enriched with such biofactor supplements.

The value of the premixes obtained by this process is higher than that obtained by mixing the isolated concentrates with another feed component, since premixtures prepared according to the invention, in particular by spraying into the feed component brought into the fluidized state, are already intimately mixed during this operation. The homogeneity of the feed composition with regard to its enrichment with biofactor supplements is very important for the perfect utilization of these active substances in the animal digestive tract, so that the invention also provides for a more efficient use of these biofactor supplements in feeding their enriched feeds.

The ingredients of the feed onto which the solution of the biofactor supplements - these active substances - are sprayed can be of both organic origin such as bran, meal or soya flour, as well as inorganic origin such as bentonite, zeolites, limestone and the like.

The significance of the invention is best exemplified in the description of several examples of applications of said biofactor supplements, which have no meaning other than illustrative and in no way limit the scope thereof. First of all, however, it should be noted that the proportion of biofactor supplements applied to feed, even as many as one component, is very low. For example, the biofactor supplement manufactured under the trade name DB-SOL-N contains, inter alia, only 1 g of Nitrovine and 120 g of lysine per kg.

For the production of a premix of Nitrovin itself, the ratio would be:

g of a 10% Nitrovin solution (1 g of Nitrovin and 9 g of water) and 999 g of feed flour provide 1,009 g of a mixture containing 9 g of water, which is dried to give 1000 g of a premix with 1 g of Nitrovin.

To produce a premix of lysine alone, the proportions of its components would be:

480 g 25% lysine solution (120 g lysine and 360 g water)

880 g feed flour

360 g of the mixture it contains

360 g of water, obtained by evaporation in an oven

000 g premix with 120 g lysine.

For both biofactor supplements, ie both for Nitrovin and lysine, a solution is used at a concentration which, with its water content and the water or moisture content of the flourized feed meal, does not burden the resulting mixture with more than 40% water. This means that, subject to this condition, important for the drying process, for the first premix, the feed flour may contain a maximum of 39.5% moisture / 40% of 1,009 g is 403.6 g. so the maximum amount of moisture in the feed flour is 403.6 - 9 = 394.6 g, which is 39.5% due to its 999 g weight.

Similarly, in the second premix, the condition is a maximum of 40% moisture in the mixture, i.e. 1,360 x 0.4 = 544 g of water. After deduction of water from the lysine solution, the maximum remaining moisture content of the feed flour is 544 - 360 = 184 g, ie 184: 8.8 = 20.9%.

After drying or evaporation of the water, the two premixes are mixed - preferably again in a fluidized state to obtain said DB-SOL-N biofactor supplement, in which the required amount of Nitrovin and lysine remains and which can then be easily mixed with the other feed ingredients.

Further examples in which the feed of the biofactor supplements can advantageously be carried out again in the fluidized state of the loose feed compositions to which these active substances are to be applied: Example 1

Inject 480 kg of 25% lysine solution onto 880 kg of 15% moisture feed flour. After drying 360 kg of water, 1000 kg of the product with the original dry matter of flour containing 12% lysine are obtained. Said product may be used in compound feed for fattening pigs.

Example 2

924.96 kg of 90% pre-dried soybean flour is injected with 75.04 kg of a solution obtained by fermentation of a culture medium of Bacillus subtilis, concentrated to 50% dry matter, containing 53 307 cheese units in 1 g. After mixing, 1000 kg of a dry matter product of 87% containing 4000 cheese units per g are obtained. The product can be used in mixtures for fattening calves and piglets without having to be dried.

Example 3

In the batch of Example 2, the pre-dried soy flour is replaced with an equal amount of pre-dried zeolites. A product suitable for chickens and pigs for fattening is obtained.

In none of these examples is there any mention of the drying of the mixture after the biofactor supplements have been injected. It is well known to anyone skilled in the feed industry what moisture conditions can be used to store certain feed ingredients. In plants where cattle are fed by directly delivering these feeds from the producer in batches that are immediately fed and not stored, there is no need to worry about drying, which again means additional energy savings. The same is true of the manufacturer of such feed supplements and feed that are directly fed to him.

The invention can also be used in the production of feed formulations where the biofactor supplements can be added with other enriched mineral, inorganic and possibly organic ingredients, and where liquid formulations such as molasses can be mixed into the feed formulations as an aqueous solution thereof. Here, however, it is necessary to take into account the temperature at which the feed is formed by pressing in order not to destroy the biofactor supplements by exceeding their maximum allowable heating.
