Description

GROWTH INTENSIFIERS FIELD OF THE INVENTION The present invention relates to an additive for intensifying growth for a compound food, which contains an organic or inorganic acid, or salts thereof, with a beneficial effect on the treatment of the compound feed, and a sulphite liquor exhausted from an acid or neutral cellulose sulfite cooking. It is known that the addition of acid to a compound feed for pigs has an effective effect on its growth and health. Furthermore, the addition of acid to the compound feed reduces the amount of compound feed consumed per kg of growth without the increased growth affecting the quality of the meat, since the percentage of meat remains relatively unchanged. This also saves on feeding costs by reducing the feeding period and promoting better housing utilization. The quality of the food is also improved, since the acid eliminates bacteria and undesirable microorganisms in the food. The effective effects in pigs of the addition of acid to the compound feed with which they feed is due to the beneficial effect it has on the digestive system. The addition of acid inhibits the Ref: 128736 activity of and eliminates unfavorable and undesirable bacteria in the pig's digestive tract. This results in a generally healthier environment in the stomach and intestinal tract of the pig. The intestinal, bacterial, natural flora achieves balance, the result is much less digestive disorders, less diarrhea and more compact manure. A low pH in the stomach also promotes an increase in the secretion of important digestive enzymes such as pepsin. This enzyme is important in the digestion of proteins. The increased secretion of pepsin results in better digestion and utilization of proteins and in this way enhanced growth. Now there are composite food products on the market, including "Format" of Felleskj0pet, which exploit this principle. It is also known that for other types of products, such as silage agents, it has been suggested that acids be used, together with an exhausted sulfite liquor (SSL) as a silage additive for grass, grain, " masque "etcetera, especially to preserve the protein content of the food (Norwegian patent No. 803321). Similarly, in European Patent Application No. A0043202, it has been suggested that an aqueous sulphite liquor composition exhausted to sulfite or lignosulfonate, organic acids and formaldehyde be used to treat animal feed containing protein or carbohydrate, In order to prolong the conservation of the food. Organic acids such as formic acid, acetic acid, etc. are commonly used as acid additives to the compound feed. However, there are a number of problems with the use of strong acids such as formic acid, which include equipment corrosion and exposure for those who handle the product. There is considerable corrosion in the storage tanks, the mixing equipment, the production line for ball food in particular. This raises operating costs and leads to an added burden of increased maintenance and system monitoring. Formic acid is corrosive to the skin and can cause damage from burns, which is why it is necessary to work with full body protection. During the formation of balls, the temperature rises to 80-95 ° C, which leads to the evaporation of some of the formic acid, the vapors of which are very dangerous in inhalation. Another purely practical problem arises in many cases in which food mills and breeders lack equipment to dose liquids.

In the present invention, the aforementioned problems associated with the use of additives of acid in the compound feed by the addition of a sulphite liquor exhausted from cooking to acidic or neutral cellulose sulfite have been reduced. The sulphite liquor exhausted from acidic or neutral cellulose sulfite cooking is highly effective in reducing corrosion. It has also been shown that the amount of acid used can be reduced compared to the amounts previously used. A reduction in the amount of acid and the addition of the spent sulfite liquor mentioned above is expected to solve the problem with evaporation of the acid in the manufacture of the compound feed. YesIn addition, the spent sulfite liquor is adsorbed on a carrier, further improvement is obtained. Through the adsorption of spent sulfite liquor in a carrier, a dry product is achieved which, in turn, can overcome the problem of food mills and breeders that do not have the systems for dosing liquids. However, it has also been surprisingly shown that the additive has a positive effect, higher than pure formic acid, on the growth of the pigs. Studies show that a synergistic effect is obtained by using both formic acid and lignosulfonate, despite the fact that the concentration of formic acid is reduced. The present invention includes an additive for intensifying growth for a compound feed containing an organic or inorganic acid, or salts thereof, with a beneficial effect on the treatment of the compound feed, and the sulphite liquor exhausted from a sulfite cooking. Acidic or neutral cellulose. The spent sulfite liquor has a pH value in the range of 1 to 10. The base used to produce the spent sulfite liquor is either calcium, sodium, ammonia or magnesium. The organic and inorganic acids with a beneficial effect in the treatment of the compound feed are formic acid, acetic acid, propionic acid, citric acid, hydrochloric acid, phosphoric acid or mixtures thereof, formic acid which is particularly preferred. The salts of these acids are ammonium salts, alkali metal and / or alkaline earth metal salts, especially NH 4 -, Na-, Ca- or Mg-. By sulphite liquor exhausted from an acidic or neutral cellulose sulfite cooking is meant the spent sulfite liquor produced by treating wood with an aqueous liquid to which sulfur dioxide and ammonia, sodium cations have been added. , calcium or magnesium mentioned above. The main ingredient in the resulting spent sulfite liquor, after the cellulose separation, is lignosulfonate. In addition, there are mono and polymer sugars and inorganic salts. Sulfite liquor exhausted to acidic and neutral cellulose sulfite can also be adsorbed to a suitable carrier in order to obtain a dry substance. By a carrier is meant a particulate, dry material. Such a material, for example, could be one of the ingredients in the composite feed, for example, soybean meal or a water-adsorbent silicate. The additive contains an organic or inorganic acid, or salts thereof, with a beneficial effect on the treatment of the compound feed, in an amount ranging from 10-90 weight percent, and a sulphite liquor exhausted from a sulfite cooking of acidic or neutral cellulose in an amount ranging from 10-90 weight percent. The additive is added to the compound feed in amounts ranging from 0.2 to 3.0%, preferably from 0.4 to 1.5% and more preferably from 0.6 to 1.0%. The following examples are proposed to illustrate the invention without limiting its scope in any way.

EXAMPLES Example 1 Feeding experiments were carried out on pigs using the following 3 food mixes: a) A compound, normal food containing the following main ingredients: Barley 65% Corn flakes 18% Bone meal 7% Soy flour 4% Fat destruction 4% Herring meal 1% b) A compound feed, normal to which 0.6% formic acid has been added, and c) A compound feed, normal to which 0.4% formic acid and 0.2% of a lignosulfonate product derived from sulphite liquor exhausted to sulfite (considered as a dry substance) has been added.

There were 24 animals in each group, each had an initial weight of 33 kg and a final weight of approximately 105 kg. The following results were obtained: Compound feed mix A b c Growth per day (g) 841 888 901 Meat percentage 53.8 53.5 54.3 Food consumption 2.85 2.75 2.73 (FUpVkg of growth) * Unit of feeding of pigs It was observed that the growth per day is markedly better with the addition of formic acid than with the compound feed alone. However, experiment (c) shows a further increase in growth, despite the reduction in the amount of formic acid. This indicates that the lignosulfonate product has __ a positively enhancing, additional effect on growth. The consumption of food is reduced by the use of formic acid and this effect is also being observed in the addition of the lignosulfonate product. This improves the remunerability of the use of formic acid, and thus with the addition of the lignosulfonate product. The percentage of meat is virtually unchanged.

Example 2 Instead of adding the formic acid mixture and the lignosulfonate product to the food in liquid form, it may occasionally be highly appropriate to add it in powder form. The experiments have been carried out to adsorb a mixture of formic acid and liquid lignosulfonate in soybean meal and also a water-absorbent silicate. The mixture contained 60% formic acid and 40% of a concentrated lignosulfonate solution considered as a dry substance. The results show that it is possible to add more than 20% of the mixture to the soy flour and more than 30% to the silicate without the annoying clutter or apparent lumping of the product. This shows that it is possible to dose the mixture to the food in powder form where this is desirable or necessary.

Example 3 Normal corrosion tests on a cold-rolled steel plate were carried out over a period of 16 days, which showed the following: Corrosion rate (mm / year) Formic acid 85% 0.88 formic acid / concentrated lignosulfonate solution 60/40 0.39 50/60 0..25 40/60 0.18 Tap water 0.08 The results show that the use of formic acid and the lignosulfonate product corrodes much less than pure formic acid.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates.
