Description

FIELD OF THE INVENTION The present invention relates to a method of supplementing the amino acid content of feeds comprising the step of treating proteinaceous feedstock with known methods, including drying one or more liquid limiting amino acid formulations during the course of drying and processing using equipment or technology known per se. we continue and finish. The protein concentrate produced by the new method is suitable for adjusting the amount of crude protein and limiting amino acids in the feed in physiologically optimal amounts and ratios in single-dose stomach and poultry feeds.

From a very large body of literature on animal nutrition and animal nutrition, we refer to the following: Kakuk-Schmidt: Ozology of Fodder, Agricultural Publisher, Budapest, 1988. Schmidt: Fodder Science, Agricultural Publisher, Budapest, 1993. Both textbooks discuss this in detail and among other things. - the effectiveness of the diet in relation to the quality of the feed and the role of amino acids. The following literature contains the composition of the diet according to the species, age, utilization of the animals and optimal nutrient requirements (Barócsai: Hungarian Codex for Animal Nutrition, I., Agricultural Publisher, Budapest, 1990).

It is also well known in the cited literature that, in order to produce animal products efficiently, based on protein concentrates obtained from the most careful processing of animal and vegetable protein feedstocks and also the most carefully formulated the active ingredients are usually not present in the amount required and the animals are unable to produce them. Monogastric and poultry feeds are mainly supplemented with lysine (L-lysine or L-lysine monohydrochloride), methionine (DL-methionine or DL-methionine hydroxy analog) and threonine (L-threonine). Of cystine, only the feed of (young) fowls needs to be supplemented, while tryptophan (DL-tryptophan) or other essential amino acids are usually found in the feed or are capable of being built up by the animals. (Kakuk-Schmidt: Supplement to Nutrition Science: Nutrition Tables, Agricultural Publisher, Budapest, 1988) However, feed cost, which accounts for about 85% of total inputs, is not negligible from the point of view of livestock profitability, which is significantly influenced by the . It is common and well-known practice in animal nutrition to use one of the known methods for this purpose (Pelczar-Reid: Microbiology, Mcgrow-Hill Publisher, New York, 1965, p. 579: Industrial Production of Amino Acids. Agroferm Hungarian-Japanese Fermentation Industry Co., Ltd. , Product guides) are added to each of the powdered final amino acid formulations as nutritional supplements during nutrition, keeping in mind the minimum levels required for optimal effect and their physiologically correct ratio (amino acid balance). With protein concentrates of animal or plant origin only, it would be even more costly, and otherwise it would be a wasteful solution to provide the desired amounts of limiting amino acids in the feed. The addition of liquid amino acid formulations for direct cost-cutting purposes or in drinking water is not widespread. Due to the uncertainties inherent in the application technology [such as achieving homogeneity of components (possible decrease in the value of the active ingredient]), we do not consider it a good solution either. From the product information of the above-mentioned Hungarian plant, as well as from oral communication, he was aware that he is marketing liquid lysine (Aqualiz-400) and mixing with extracted sunflower meal. However, the latter product (Napliz) is specifically recommended only as a substitute for extracted soybean meal.

The foregoing and widespread restriction amino acid supplementation practice has the advantage of being safe, but has the disadvantage of being expensive. In spite of the latter, neither the cited literature nor any other literature to which we are aware has found data to modernize amino acid supplementation technology to reduce feed costs.

In order to overcome the disadvantage of providing the recommended limiting amino acid content of industrial compound feeds and protein concentrates, we have aimed to develop a new method that improves the amino acid composition of protein concentrates and reduces the cost of feeds while maintaining their effectiveness.

The inventive idea is based on the discovery that high-quality animal and vegetable protein carriers or mixtures thereof in defined proportions are known in the art (U.S. Patent No. 204,415, "A Process for the Preparation of Animal and Vegetable Amino Acid-Enriched Protein-Enriched Protein processing, or patent application HU 206 965, entitled "Process for the Energy-Efficient Production of Concentrates of Animal and Vegetable Proteins"), has little or no degradation of protein and thus maintains virtually constant levels and proportions of amino acids specific to the particular feedstock. Thus, the measured or calculated dry matter and active substance content of the starting materials can be used to determine with great precision the expected mass of the protein concentrate to be formed, as well as the crude protein and amino acid content,

- the active ingredient (s) of the liquid amino acid preparation (s) can withstand the heat applied in the processes referred to without damage,

- in these known processes, the addition of whole or defatted butterflies or other oilseeds or flour is particularly advantageous for drying the heat-treated wet and usually greasy stock (hereinafter referred to as "paste"),

HU 220 890 Bl

- none of the liquid amino acid formulations experimentally administered during the processing of the protein carrier raw materials known per se, has adversely affected either the implementation of the technology or the quality of the final product.

According to the present invention, in a drying step of 10 to 25% by weight of an oily seed or flour formed during the processing of animal and vegetable protein carriers, known in the art (patent application No. 204 415), (t)%, preferably from 15% by weight to a moisture content of 1% to 20% by weight of the calculated dry matter of the mixture, is added to the mixture in the dryer while the process is carried out and terminated in a manner known per se one or more liquid limiting amino acid preparations (lysine, methionine, cystine, threonine, tryptophan) based on the calculated dry matter and limiting amino acid content of the mixture and its intended use (animal species, age, for example) quantities. The final protein concentrate obtained is mixed with 4-12% by weight of mono gastric and poultry feeds.

It is noted herein that the cystine and tryptophan content of the protein concentrate produced by the known process, as calculated and measured at the dosage recommended in this process, is sufficient to provide an optimal level of cystine and tryptophan in the target diets. However, lysine, methionine and threonine should always be added to the protein concentrate.

The procedure is illustrated in more detail by the following examples.

The advantage of the new process is that its implementation can be easily integrated with the well-known processing technology of protein-bearing raw materials by on-site adaptation. So without the extra investment of just one simple operation, it solves the nutritional-physiologically justified amount and proportion of protein concentrates and through them targeted feeds with limiting amino acids.

A further advantage of the process of the invention is that

- allows simple but safe administration of cheaper liquid amino acid supplements, which are otherwise as effective as powder formulations,

- the protein concentrate supplemented with the limiting amino acids of our process is not only better quality but also relatively cheaper,

- the use of the new product is also simpler and more economical in the production of industrial compound feed, as several operations can be omitted without risk (production of solid amino acid preparations and their marketing as separate feed supplements).

The invention is illustrated by the following non-limiting Examples, which are intended to illustrate the present invention in more detail.

It has been demonstrated that the following three limiting amino acids are sufficient to supplement the protein concentrate, instead of five, by increasing the amount of threonine by reducing the amount of lysine and / or liquid methionine and / or liquid threonine, including lysine and methionine.

Example 1

200 kg of slaughterhouse mixed confiscation and 200 kg of pork meat are sterilized-pulp by a known method, the sterile hot mass is dried in a manner and apparatus known per se and, when 25% moisture content is reached, 140 kg of whole-oil, first class crude soybean is added. After known heat treatment inactivation, the mixture is further dried and, at a moisture content of 15% by weight, based on the calculated dry matter (232.92 kg) and limiting amino acid content and its intended use, 22.95 kg (9.85 kg) is added to the mixture. liquid limiting amino acid supplement containing 8.53 kg (37.17% by weight) of 70% liquid lysine, 4.75 kg (20.70% by weight) of 88% liquid methionine and 9.67% kg (42.13% by weight) of liquid threonine. Thereafter, drying is continued in a known manner and apparatus until the moisture content of the mixture is reduced to 7.0% by weight, and the work-up is then completed in a known manner.

The total amount of the final product obtained is 268.00 kg, the amino acid content, the content of which, the trypsin inhibitory effect (the natural heat - sensitive antinutritive active ingredient of the raw soybean) and the microbiological qualification thereof were determined by known laboratory tests (Barócsai: , 1990).

The protein concentrate produced by the new process is checked at the time of preparation and after 90 days of storage at 13-16 ° C. In all cases, the results for TIU (Tripsin Inhibitor Unit) and live germ count are within the limits permitted in Part I of the Feeding Code. Therefore, now and in the following, only the most important amino acid and content values for the evaluation of the present invention are given:
