Abstract

Usage: in feed preparation. SUMMARY OF THE INVENTION: A method is proposed for preserving plant raw materials with organic acids with the addition of nitrogen containing substances, in which the ratio of nitrogen to nitrogen containing substances and acid is set in a ratio of 0.1-8: 1 and applied in a dose of 0.4-4% to the preserved raw material. The amount of the injected components — the acid and the nitrogen-containing substance — is determined by equations taking into account the dry matter and crude protein content in the feedstock. 1 tab.

Description

The invention relates to methods for preserving plant raw materials containing nitrogen in their composition and used for feeding ruminants.

The purpose of the invention is to improve the quality and safety of feed from different-quality plant raw materials.

According to the method, the nitrogen-containing substance and the organic acid are mixed at a nitrogen to acid ratio of 0.1-8: 1 and the resulting mixture is introduced into the plant raw material at a dose of 0.4-4% of the total mass.

The method is carried out as follows.

Before being deposited in plant raw materials, the content of dry matter and crude protein is determined. Then, using equations (1) and (2), the number of components introduced into the raw materials is determined.

(free member). Example 1. A dried mass of cereal grasses containing 75% dry matter and 12% crude protein in a dry matter is enriched in nitrogenous matter to a crude protein content of 25% and preserved with formic acid. Urea (carbamide) is used as a nitrogen-containing substance. Urea demand is determined by equation (1). At 3.75%. The protein equivalent of urea is 2.6 (i.e., 0,, 25, where 0.416 is the nitrogen content of 1 kg of urine

guilt, kg, 6.25 - nitrogen conversion factor into crude protein).

The need for formic acid is determined by equation (2). Y - 0.20%. The total dose will be 3.75 + + 0.20 3.95% by weight of raw materials.

Example 2. Corn containing protein in the dry matter of 6.3%, dry matter 19%, canned by the known and proposed methods. With a given protein content in the final feed of 8%, the need for urea was 0.15%, for formic acid, 0.25% of the amount of raw material, while the total dose of preservative was 0.4% of the raw material. For a given protein content in the finished feed of 15%, the need for preservatives was 0.72 and 1.19%, respectively.

Data on the results of enrichment and preservation are presented in Table I.

the face, where the ratios and doses of urea and formic acid are given for preserving freshly mown and cultivated grass grasses containing 19, 58 and 75% dry matter and crude protein in a dry substance of 22.4, 17.3 and 12.0%.

When preserving in a known manner, a predetermined protein content is not achieved, especially when preserving the spent mass, and an increase in gas loss during fermentation is allowed.

The advantage of the proposed method

This is because it ensures better preservation of the raw materials with optimal acid consumption and allows you to regulate the protein content in the finished feed.
