Abstract

Usage: in feed production. SUBSTANCE: powdered sourdough prepared on the basis of slurry filtrate treated with a 3% methanol solution mixed with bran and dried to a powdery state is added to the crushed and moistened vegetable raw materials. Ferment is added at 0.0001-0.0003 h, for 1 h. Raw materials.

Description

The invention relates to the field of agriculture .. and can be used in feed production, based on the processing of crop waste.

The purpose of the invention is to simplify the method, the use of a filtrate of a widespread biologically active substance - slurry, treated with a 3% solution of methanol, subsequently mixed with bran and dried at room temperature.

A comparative analysis of the claimed solution with the prototype shows that the claimed method differs from the known one in that the decomposition of complex raw materials into simpler compounds is carried out using starter culture prepared using ocv slurry filtrate.

Examples of feed preparation carried out on a collective farm farm in the village of Japaridze, Citeltskaroy district of Georgia.

Example 1. Wheat straw in an amount of 500 kg (1 h) was passed through a coarse feed chopper, placed on an open area, moistened with water to 40-50% humidity, 50 g (0.0001 h) of yeast powder diluted 5 l of hot water and left to ripen. After 15 days, the nutritional value of straw increased. At a moisture content of 15%, the feed contained: crude protein 7.2%, crude fat 1.82%, crude fiber 27.2%, phosphorus 0.52%, ammonia nitrogen 2.7%, nitrate nitrogen 3.1%, feed units 0.4. ; Example 2. Wheat straw in an amount of 500 kg (1 h) was passed through a coarse feed chopper, placed in an open area, moistened to a moisture content of 20-45%, 100 g (0,0002 parts) of powdered yeast diluted 5 l of water and left to ripen. After 15 days, pi. straw straws more than doubled. At a moisture content of 15%, the feed contained: crude protein 7.6%, crude fat 1.83%, crude fiber 27.1%, phosphorus 0.51%, ammonia nitrogen 2.8%, nitrate nitrogen 3.0%, feed units 0.42.

EXAMPLE 3. Wheat straw in an amount of 500 kg (1 h) was passed through a coarse feed chopper, placed on an open area, moistened with water to a moisture content of 40-45%. 150 g (0.0003 h) of a starter powder diluted in 5 l of hot water were added. After 15 days, the nutritional value of straw more than doubled. At a moisture content of 15%, the feed contained: crude protein

7.8%, crude fat 1.81%, crude fiber 27.3%, phosphorus 0.51%, ammonia nitrogen 2.7%, nitrate nitrogen 3.1%. feed units 0.42.

Thus, the optimal food preparation option is option 2, which achieves a maximum feed nutritional value of 0.42 feed units at a powder starter consumption of -100 g per 500 kg of straw cutting. When the dose of starter culture is reduced to 50 g per 500 kg of straw cutting (Example 1), the nutritional value of straw is lower, and when the dose of starter culture is up to 150 g per 500 kg of straw cutting (Example 3), the nutritional value of the final product does not increase.

Compared with the prototype, the proposed method allows to obtain feed of the same quality using a simplified technology with

excluding several feed additives. Ready-made feed can be fed to livestock fresh, granular, briquetted, dried in a dryer, silage.

Claims (1)

Formula and sampling A method for preparing feed, which involves grinding vegetable raw materials, moistening and introducing starter culture followed by aging, which is based on the fact that, in order to simplify the technological process, the starter culture is prepared from the filtrate of the liquid fraction of manure treated with a 3% methanol solution, mixed with bran as a filler and dried to a powder state, with 0.0001-0.0003 parts of starter being added to 1 part of the feed.
