Abstract

Usage: in agriculture, in particular in the technology of preparation of feed. SUBSTANCE: lignin-containing raw material is cleaned of non-feed inclusions, mixed with milk of lime in the ratio 1: (0.1-1) and the resulting mixture is introduced in an amount of 1-8% of the total dietary weight on a dry matter basis. As lignin-containing raw materials, sulfite liquor processing wastes and wood processing wastes are used (hydrolysis lignin, lignosulfonates, cellolignocorm, mineral carbohydrate additive, belugmin, etc.). 1 s.p. crystals, 1 tab.

Description

The invention relates to agriculture, in particular to a feed preparation technology.

A known method of preparing food, comprising introducing into the main diet lignin-containing raw materials - spent sulfite liquor in an amount of 0.25-3.0% based on dry matter.

Such a feed can increase milk yield. However, the resulting livestock products, when using this feed or other known feeds, have a sufficiently high cholesterol content, which is the main cause of the development of atherosclerosis.

The purpose of the invention is to improve the quality of feed, the use of which leads to a decrease in cholesterol in livestock products.

This goal is achieved in that before introduction into the main diet, lignin-containing raw materials are cleaned of non-feed inclusions, mixed with milk of lime in a ratio of 1: 0.1-1 and

the resulting mixture is introduced in an amount of 1-8% of the total weight of the diet on dry matter, and also that waste from processing sulphite liquor or waste from wood processing (hydrolysis lignin, lignosulfonates, celloligno-feed, carbohydrate-mineral additive, are used as lignin-containing raw materials) belugmin and others).

Introducing a mixture of purified lignin-containing raw materials with milk of lime into the main diet increases the adsorption, ion-exchange and binding properties of the feed with respect to cholesterol and bile acids found in the intestinal tract of animals. Due to this, cholesterol-containing substances are not absorbed into the blood, but are excreted from the intestinal tract.

The method is illustrated by the following examples.

1. Lignin-containing raw materials - sulfite liquor, purified from non-feed inclusions according to method 718080 and conversion /

mixed in a carbohydrate-mineral supplement, mixed with milk of lime in a ratio of 1: 0.1. The resulting mixture was introduced into the feed in the ratio of 8% to dry matter.

2. Lignin-containing feed - hydrolyzed lignin is mixed to neutralize

with milk of lime in a ratio of 1: 1. A 5% mixture is added to silage, haylage and other feed.

3. Lignin-containing raw materials — lignosulfonates are mixed with milk of lime in a ratio of 1: 0.3. The resulting mixture is introduced into the feed mixture in an amount of 3%

to dry matter.

4. The lignin-containing raw material -elugmin in liquid form is mixed with milk of lime in a ratio of 1: 0.2, the mixture is added to haylage and other roughage in an amount of 2.5%.

5. Lignin-containing raw materials — the cellolignum feed is mixed with milk of lime in a ratio of 1: 0.4 and introduced into the feed mixture in an amount of 1%.

6. Lignin-containing raw materials — lignosulfonates are mixed with milk of lime in a ratio of 1: 0.05. The use of such a mixture is not possible due to the low pH and low effect.

7. Lignin-containing raw materials - a carbohydrate-mineral additive is mixed with milk of lime in a ratio of 1: 0.1.

The resulting mixture was added to the feed in an amount of 9.0%. Compound feed becomes very moist and its distribution through the feeders is difficult, sticks to the blades,

The table shows the dependence of the cholesterol content in the blood and liver of animals on the ratio of the mixture of lignin-containing raw materials with milk of lime and the amount of the mixture introduced into the diet.

The table shows that the cholesterol content in the blood and liver of animals is significantly lower inside the declared intervals than outside and when using the food according to the prototype.
