Description

 The invention relates to agriculture, in particular to the production of feed.

 It is known the use of organic acids (formic, propionic, acetic, KNMK) for preserving feed grain (Fedoseev P.N. Gundorov V.V. Sokolov A.V. Use of chemicals in the preparation of feed. M. 1988, p. 47-64) . The main reason that inhibits the widespread distribution of these preservatives is the high economic costs of their transportation, storage and incorporation into the silage, and the positive effect of canning is achieved with large doses (0.5% of the preserved mass) and with strict compliance of acid quality with GOST parameters. If you violate the rules for the transportation and storage of these acids (for example, in un galvanized containers, in the vicinity of chemicals, in violation of the tightness of the container), as well as overdose when introduced, there is a danger of poisoning the animals. Grain treated with organic acids has a sharp, specific smell and animals need to be trained to it gradually. In addition, working with any acids requires strict observance of safety precautions, special protective clothing for workers, as well as technological equipment, dispensers, sprayers, mixers, which greatly increases the cost of their use.

 The closest technical solution is the use of sourdough type "Kazakhsil", which are used when laying the dry mass of grain crops.

 However, these starter cultures did not receive widespread use in the harvesting of feed grain due to the fact that their main active principle (amylolytic lactic streptococcus, propionic acid bacteria and pentoformation lactic acid bacteria) loses its activity and viability when used on a silage mass below 40% moisture and does not provide safety of nutrients.

 The purpose of the invention is to increase the safety of feed grain and its quality, reducing the cost of procuring feed by using components of biological and food preservatives in a nutrient medium.

 This is achieved by the fact that the bioconservative "Kazakhsil", a type of PCB (propionic acid bacteria) is not diluted with water, but with molasses with BMK (a carbohydrate product of processing the maize plant), which significantly increases its activity and vital activity.

 To enhance the preserving effect, the food preservative DHA (3-acetyl-6-methylpyrandion-2,4) is additionally introduced, which does not inhibit the activity of propionic acid bacteria.

The preservative is a synergistic mixture (see table 1). It is prepared as follows: syrup was preheated to 33-35 ^{° C} and introduced propionic acid bacteria are then added preservative DHA and mixed thoroughly. The ratio of components, wt. Propionic acid bacteria 10-12 Preservative DHA (3-acetyl-6-methylpyrandion-2,4) 10-12 Molasses 76-80
The effectiveness of the preservative exceeds the effectiveness of the preparations "Kazakhsil" and DHA, used separately (see table 2).

 The preservative ensures the safety of nutrients of feed grain by 97-98% for 10 months. As a result of biochemical processes, the quality of feed and its eatability are significantly improved (there are practically no residues).

 The use of a preservative significantly reduces the cost of harvesting feed grain.
