Description

one

The invention relates to feed for farm animals and can be used for fattening young pigs.

Fattening rations for piglets are known, in which the required amount of proteins is provided by the inclusion of both traditional and non-sparing feeds. The latter are fodder yeast grown on products from the hydrolysis and oil refining industry fll.

However, yeasts are capable of only heterotrophic growth, i.e. for their production requires organic substances, stocks or production of which are limited. Yeast biomass of paraffin-grown oil (the so-called protein-vitamin concentrate, BVK, contains residual amounts of hydrocarbons that adversely affect animals.

A source of feed protein is also known - biomass of hydrogen sulfide of young bacteria (BVV), characterized in that the synthesis of BVB is the most efficient way of using electricity to produce protein through water electrolysis;

rodoxyl bacteria yudyh to autotrophic growth ensures the production of biomass, regardless of the sources of organic raw materials; No substances that are known to have toxic properties are used in growing hydrogen-oxidizing bacteria; Bacteria hydrogenous acid can develop a high growth rate, - BHB is distinguished by a high protein content (up to 70%) with good amino acid composition; with long-term use of BVK in the diet of laboratory animals there is no toxicity.

A known method for producing protein. I.s of bis isassa cells of hydrogen-acid bacteria of bacteria. Like all types of microorganisms with a high growth rate, hydrogenated bacteria are characterized by a high concentration of nucleic acids in the cells. The method allows to reduce the content of nucleic acids in BHB 10 times. The product obtained in this way can be used as a source of protein in human nutrition and the feeding of farm animals 3,

However, carrying out denucleotization

30 BVB requires additional material

and labor costs, which ultimately increases its cost.

The norms of protein content in the diet of 1.4 young fattened pigs are known, for example, the diet prepared in accordance with these standards, wt%:

Barley Barrel 86.00 Premix0.94

Herbs for alfalfa flour. 3.33 Soybean Meal5,73

Fish meal1.38

M co-costa

flour1.11

Mel 0.60

Sodium chloride, 91 However, the need for pigs in animal protein in a well-known diet is provided by the scarce traditionally used animal feed: fish and vegetable flour.

The purpose of the invention is to save animal protein.

This goal is achieved due to the fact that the ration additionally contains non-denucleated. Biomass of hydrogen-acidifying bacteria in the following ratio of components, wt.%:

Barley dert 85.72-87.14 Premix0.90-0.98

Undenucleotized biomass of hydrogen-oxidizing bacteria 0, 81-0.97 Biomass of hydrogen-oxidizing bacteria is a collection of cells of hydrogen-acid bacteria containing up to 70% of the conditional protein (X6,25), the amino acid composition of which is close to that of beef meat.

Table 1 presents examples of the implementation of diets for young suns in the period of feeding with a content of native biomass of hydrogen-acidifying bacteria of 0.81% and 0.97%.

The proposed ration for fattening of young pigs was tested in a scientific and scientific experiment in which 2 groups of 20 heads of pigs each participated: I group - control, in the diet of which animal proteins are traditionally used feed (fish and mash meal), II group , in the diet of which 50% of the quota of animal proteins are replaced by an amount of BVB equivalent in protein.

Table 2 shows the average daily composition and some characteristics of the ration of pigs in the experiment.

5 in an experiment tested by BVB, obtained on a pilot plant in a continuous mode of cultivation without carrying out denucleotization, since the short lifespan of the fattened pigs does not allow for the possible adverse effects on the organism of an increased content in the biomass of nucleic acids. In the experiment, no difference was found between the experimental group of the pigs and the control group in terms of zootechnical, physiological or biochemical indicators, t Table 3 shows some indicators of the economic efficiency of using BVB in the diets during fattening.

In another experiment, diets with different levels of replacing animal proteins with BVB protein are tested. The best results were obtained in the group of pigs, animal proteins of which are 63.5% represented by BVB proteins.

Thus, the data presented indicate the possibility

0 partial replacement of deficient traditionally used feed of animal origin. In the diet of fattened young pigs with the equivalent of protein biomass of hydrogen-acidifying

d bacteria without prior denucleotization. The introduction of BVB in pig breeding allows substantial. reduce protein deficiency in livestock. In order to achieve the same economic effect as the existing piglets, the selling price of the biomass of hydrogen sulfide bacteria can be in the order of 1060 rubles. per 1 ton. Reducing the cost of biomass allows an even greater increase in the economic effect of introducing BWB into the national economy.
