Description

The invention relates to feed production and can be used in the preparation of animal feed and feed mixtures for farm animals and poultry.

It is known to use fermented fruit and vegetable waste (2) as a protein component of rapeseed meal as a protein component in feed rations.

The disadvantage of this method is that rapeseed meal contains physiologically unfavorable erucic acid, thioglucosides, which limits its feed value. The disadvantage of using fermented fruit and vegetable additives is the low protein content of 20%.

The closest in essence to the proposed composition of the feed mixture is a composition that includes as a protein supplement in the preparation of the feed mixture for pigs and cattle sunflower, soybean, cottonseed meal and fish meal (3).

The disadvantage of this method is that protein supplements contain a low amount of protein and a significant amount of fiber. Other disadvantages: anti-nutritional substances are present in sunflower and cottonseed meal. Protease inhibitors, hemmagglutinins in soybean meal and gossypol in cottonseed, i.e. compounds with a negative effect on a living organism, which significantly reduces their feed value. The use of fishmeal negatively affects the palatability of livestock and poultry products.

The essence of the invention is the composition of the feed mixture for farm animals and poultry, providing improved quality and harmlessness of feed for farm animals and poultry and its cheaper.

The use of a protein preparation obtained from biomass of earthworm as a protein feed additive by homogenizing the biomass, extracting the protein with a 0.01-0.5% alkali solution, with a ratio of biomass and extractant 1: 3-1: 11, temperature 40- 100 ° C and constant stirring for 10-60 minutes, removing insoluble components, precipitating the protein at the isoelectric point, allows you to achieve an ultimately total result due to the high quality of the drug in terms of protein and essential amino acids, lack of anti-nutritional Connections (Table 1).

The technical result is achieved in that the feed mixture for farm animals and poultry, including protein and mineral supplements, components of plant origin and fodder yeast, as a protein supplement contains a protein preparation obtained from earthworm biomass, in the following ratio, wt.%:

Protein preparation 0.5-20.0 Mineral supplement (including food salt 0.9) 2.0-7.0 Animal components 0.5-10.0 Herbal ingredients Rest

The proposed method produces feed with a protein preparation produced in local conditions, replacing scarce, imported protein components for animal feed and feed mixtures.

The composition of the feed mixture is prepared according to the formulation corresponding to the type of animal, bird, age group and productive orientation according to "Instructions for the use of recipes for farm animals" N009-2 and guidelines for the calculation of recipes for animal feed and BVD using a computer. A protein source is introduced, a protein preparation in an amount of 0.5-7.0% for poultry, 0.5-10% for pigs, 0.5-% for cattle and, with stirring, components of animal origin, microbial synthesis products, mineral additives (table 2).

The protein preparation is obtained by homogenizing the mass of earthworm to a homogeneous consistency, extracting the protein from the suspension with a 0.01-0.5% alkali solution, with a ratio of 1: 3-1: 11, 140-100 ° С, constant stirring for 10 -60 minutes Then insoluble particles are removed. Protein is precipitated at the isoelectric point, the protein paste is dried. The separated protein is dried to a moisture content of more than 12%. The protein preparation has the form of a powder, grains or granules of light brown or brown color. The protein content is 58.2-90.0%, the sum of essential amino acids 46.55-48.6%, lipids - not more than 0.1-10.0%. Protein preparation differs from meal by a higher degree of protein assimilation by animals and birds.

The quality and harmlessness of compound feeds and feed mixtures are increased compared to feeds prepared in a known manner, due to a decrease in the content of anti-nutritional substances and an increase in the quality and quantity of protein (78.0-93.0%), and a decrease in fiber content.

The proposed composition is obtained in the following sequence.
