The invention relates to a feed which ensures optimal utilization of feed energy, which contains 50-90%, preferably 60-70% of non-protein nitrogen of its total nitrogen content and which is obtained by acid hydrolysis from a plant-derived substance containing pentosan, cellulose and / or lignin or a mixture of such substances and non-protein. a mixture of nitrogenous substances in the form of a substance to which other feed materials may have been added. The invention also relates to a process for the preparation of this feed.

It is well known that the economical feeding of animals throughout the world suffers from a general lack of protein. Animal organisms can receive the protein in amino acid degraded form. Attempts are known to replace at least some of the proteins by feeding substances that do not contain nitrogen as a protein. These experiments led to certain results in that a protein can be synthesized from this non-protein nitrogen in the ruminant body. However, in ammonia with more than one cavity in the stomach, the ammonia released by forced hydrolysis of non-protein nitrogen but nitrogen-containing substances (e.g. * stream) in the digestive system limits the use because the anmoniac image of animal blood rises and moves to the alkaline region. Although the level of ammonia in the blood in the liver decreases as a result of the formation of urine, this only happens up to a certain limit, from which point symptoms of poisoning already begin to occur, often leading to the death of the animal. Acting on a practical scale, this stimulus threshold 30 # corresponds to replacing the need for total nitrogen with non-protein nitrogen. By giving this amount of nitrogen as a urea, an acclimatization period of another 15-20 days is required.

Virtanen's experiments (Science, 1966 Band 153, No. 37) covered the need for total nitrogen with urea and mud with non-protein nitrogen compounds. However, these experiments have only a theoretical value, as only chemically pure substances (e.g. Oi-cellulose or sucrose) could be used as feed ingredients.

Various so-called wastes formed from polysaccharide-containing vegetable waste in acid hydrolysis are useful as feed materials under preferred conditions. Such feed materials based on by-products were 50% successful. nitrogen utilization to cover 75% of the total nitrogen requirement with urea nitrogen. In this case, there is no generally known fear of poisoning and no habituation time is necessary. When such feed materials are used, 19,000-21,000 calories are required to produce 1 kg live weight (Allattenyesztes, 1971, Band 20, no. 7, page Ui). This value corresponds to the general feed utilization standard (Nature, 1967, Band 216, No. 5 116, page 721).

A method is also known for limiting the disadvantages of urinary nutrition by co-feeding inorganic salts, preferably sodium chloride (Hungarian Patent 156,601).

It was now surprisingly found that the use of certain types of compound feeds derived from vegetable residues by feeding feed ingredients in certain proportions increased the energy yield of the mixture and also improved other properties, leaving a very high 75/5 urea nitrogen to total nitrogen and 50/5 nitrogen utilization unchanged. This product, which is special in terms of quality and composition, guarantees 20-25% of nutrients converted into energy. It has been found that energy utilization increases so that energy consumption in meat production from the general I96OO kcal / kg decreases to 15000 kcal / kg, while in milk production instead of the normal value of 1100-1200 cal / kg it reaches values between 800-900 cal / kg , wherein the amount of non-protein nitrogen is 50-90% of the total nitrogen in the feed.

The invention is based on the finding that energy-rich carbohydrates under certain quality enrichment conditions obtained from vegetable residues can be better utilized when the given ratio of these enrichment products to non-protein nitrogen-containing nitrogen is altered by non-protein nitrogen short-chain fatty acids bound by the large surface area of the substance described.

The feed according to the invention is characterized in that the substance obtained by acid hydrolysis 2 has a specific surface area of at least 10 dm / g and an acid content of 5-50 g, preferably 10-1 + 5 g, acetic acid equivalent / kg dry matter, and that the carafe origin. The amount of acidic solid present, in terms of dry matter per 1 g of non-protein nitrogen, is 3 to 20 g, preferably 8 to 10 g.

A method for preparing this feed has also been developed. The process according to the invention is characterized in that at least 10 dm / g of a specific surface, preferably by hydrolysis, of comminuted dry plant material and / or a mixture of such substances is acidified until a concentration of 5 ~ 50 g, preferably 10-1 + 5 g is reached. acetic acid equivalent / kg dry matter, and the product obtained is homogenized with a substance which does not contain nitrogen as a protein nitrogen and, if appropriate, with other feed materials.

In addition to slowing the release of ammonia, organic acids on large specific surfaces are also able to act as an easily exploitable source of microorganisms, which in this way have the ability to react in addition to protein-nitrogen pretreatment to treat certain types of polysaccharide products in good yield.

An additional advantage of the feed according to the invention is that its use does not require the acquisition of specific and difficult-to-obtain feed additives, but can be used in combination with other commonly used feeds.

The feed according to the invention can be used throughout the year, continuously, without other feed materials.

The invention is illustrated by the following examples.

Example 1 Several polysaccharide-containing substances according to Table 1 were treated.

The selected raw material was irrigated by spraying at atmospheric pressure with water containing U- # acetic acid until the humidity was Uo%, and then treated with 10 aty of saturated steam for 1 hour at 175 ° C, the amount of steam being 2.1+ times relative to the dry matter content of the raw material.
