The invention relates to agriculture and can be used to extend the forage base in animal husbandry and receive feed additives.

A method of obtaining belkovosoderzhaschie feed product of substandard seeds of sugar beet (melosira) [1]. The method consists of obtaining the feed product of sugar beet seeds by grinding, extraction with hydrochloric acid and subsequent precipitation of the feed product. The disadvantage of this method is the low content of lysine in the protein part of the feed product.

The objective of the invention is to increase the content of lysine in the target product.

The problem is solved in that in the known method of obtaining fodder product from vegetable feedstock to the main raw - beet seeds type soybean meal at a ratio of 10:2-3, respectively, according to the invention.

The method is as follows. Flour seeds beet and soybean meal are mixed in a ratio of from 10:1 to 10:4, where the variable is soybean meal. Mixtures are subject to comprehensive water and acid extraction, precipitation of the protein complex in the isoelectric zone, washing and drying. The resulting product is analyzed for content of protein, starch and oil. In the protein is determined to provide the e independent of amino acids.

Example 1.

Mix flour seeds beet and soybean meal for different examples are mixed in the ratio of 10:1 to 10:4 and placed in the extractor. Pour an appropriate amount of 0,125M hydrochloric acid. The extraction is conducted at a temperature not exceeding 40°With constant stirring for 30-40 minutes Extract containing the protein is separated from the insoluble fraction by decanting. The remaining sludge is processed three times with hydrochloric acid and washed with water. And acid take 3 times less than the initial volume, mixing time reduced to 10 minutes, and settling - up to 15 minutes Primary extract and the extract obtained after treatment of sludge are mixed in a container and add in the mixture of 2M solution of alkali in the ratio extract:alkali=20:10. Mix and incubated the mixture for 10 minutes Lead acid mixture to pH 4-5 (in this area are isoelectric point of the protein components). Phase precipitate the protein-lipid starch complex twice washed and dried at a temperature not above 60°C.

Table 1 shows data on yield and composition of the obtained feed products. The data in table 1 show that increasing the share of soy meal in the mixture up to a certain limit (10:3) causes an increase in the overall yield of the target product with 12,47 to 15,99%. Then there is some of the decline overall product yield. The study of complex product explains this fact. The increase in the share of soybean meal from 10 to 40% leads to ambiguous changes in the composition of the complex. The protein content significantly increased from 41 to 61%, while the starch content decreases almost in 2 times. Also decreases and the oil content of the target product. Thus, given the biochemical composition of the mixture components, it is possible to obtain a final product with a given composition and to vary it depending on its future use.

The main aim of the development was to obtain feed product with a high content of lysine is the most important essential for human and animal amino acids. Table 2 presents data on the content of essential amino acids in the target product based on the ratio of raw materials. Analyzing the data in table 2, it is possible to make an unambiguous conclusion that the addition of soybean meal to the flour of the seeds beet dramatically increases the lysine content in the final product. The content of other essential amino acids exposed to less quantitative changes, except for methionine and cystine, which share significantly decreases with increasing components of soybean meal. As mentioned above, soy protein depleted in sulfur-containing amino acids.

Thus, the most optimal is the first variant is the ratio of flour seeds beet and soybean meal in the range from 10:2-3. When this is achieved the maximum total yield of the target product. The content of lysine and sulfur - containing amino acids methionine and cysteine in the protein product meets the standard of FAO/who.
