A composition for preventing and treating swine dysentery or for improving the productivity of pigs, which contains a compound represented by the formula: wherein R 2 and R 3 each represent hydrogen or an acyl group derived from a carboxylic acid. Swine dysentery is a contagious intestinal infection characterized by mucous and bloody diarrhea caused by Treponema hyodysenteriae, and its occurrence is recognized in most countries where pigs are raised. [Roncalli, RAand
Leaning,WHD:Abstr.4th Congr.Intern.Pig
Vet.Soc., Iowa, USA (1976)], and once they occur, they become endemic and are extremely difficult to clean. For this reason, the reality is that, especially when raising multiple pigs, large economic losses are caused due to the death of affected pigs and reduced growth. Various drugs have been used to prevent and treat swine dysentery, but none of them have been necessarily satisfactory, such as insufficient efficacy or safety issues. Although research into vaccines and the like is progressing, sufficient results have not been obtained, and nothing that is satisfactory for practical use has yet to be completed. As a result of intensive research based on this technical background, the present inventors have obtained new knowledge that the compound () has remarkable preventive and therapeutic effects against swine dysentery that cannot be achieved with conventional drugs. Furthermore, they found that the compound () promotes growth, improves feed utilization, increases pig productivity, and is extremely beneficial for livestock management. That is, the present invention is highly effective against swine dysentery by containing the compound (2), and is highly safe for preventive treatment of swine dysentery, as well as for improving pig productivity by promoting growth and improving feed efficiency. The present invention provides a composition of the invention. Compound () is a compound of Streptomyces rochei var. volubilis, which is collectively called the lankacidin group.

Each is described in Publication No. 74. Streptomyces rothiei val volubilis, which is the producing bacterium of lancasidin A, C, lancasidinol A, and lancasidinol, has been given a microorganism accession number by the Fermentation Research Institute and the American Type Culture Collection.
Deposited as IFO12507 and ATCC 21250, respectively. The acyl group derived from carboxylic acid as R 2 and R 3 in the above general formula () is a lower fatty acid residue (e.g., formyl, acetyl, propionyl, butyryl, isobutyryl, valeryl, hexylyl, etc., preferably having 1 to 7 carbon atoms). preferred) and aromatic carboxylic acid residues (e.g., aryl carboxylic acid residues such as benzoyl, heteroaromatic carboxylic acid residues such as nicotinoyl), and these lower fatty acid residues are substituted at the terminal with a phenyl group. (eg, phenylacetyl, phenylpropionyl, etc.). Among the compounds () used in the present invention, those in which R 2 and R 3 are each hydrogen or a C 2 -C 4 fatty acid residue are particularly preferred. Among them, lankacidin A, lankacidin C, lankacidin C14-
It is preferable to use propionate, 8-acetate, 8-propionate, lancasidinol A, lancasidinol, or a mixture thereof. In particular, lankacidin A or/and lankacidin C are advantageously used. The composition for pigs of the present invention may contain one type of compound represented by compound (), or may contain several types of compounds () at the same time. Furthermore, the above-mentioned fermentation medium of Streptomyces rothiei vulubilis can be used as it is as a dried product or an extract thereof. The composition for preventing and treating swine dysentery or for improving swine productivity of the present invention is prepared by diluting the compound () with a solid or liquid diluent, or without diluting it, or stabilizing it by coating, etc. It is manufactured in the form of powders, granules, tablets, liquids, pastes, capsules, injections, etc., or by adding it directly or once dispersed in a diluent to feed, drinking water, etc. Any diluent may be used as long as it is physiologically harmless in itself, and it is more preferable to use a diluent that can be used as feed or a component of feed. Examples of solid carriers include barley flour, wheat flour, bare wheat flour, corn flour, soybean flour, soybean meal, rapeseed meal, rice hulls, rice bran, de-fingered rice bran, corn flour, potato flour, tofu meal, starch, lactose, sucrose, Glucose, fructose, yeast, waste yeast, fishmeal, talc, acid clay, clay, etc. are used, and examples of liquid carriers include water, physiological saline, and physiologically harmless organic solvents. Other appropriate adjuvants such as emulsifiers, dispersants, suspending agents, wetting agents, thickening agents, gelling agents, and solubilizing agents may be added in appropriate amounts. Furthermore, preservatives, bactericides, antibiotics, enzymes, lactic acid bacteria preparations may be added, and vitamins, minerals, amino acids, etc. may also be added to these compositions. The dosage of the composition for preventing and treating swine dysentery or for improving swine productivity of the present invention can be appropriately selected depending on the age of the pig, symptoms, administration method, etc.; () about 0.05 to 25 mg/
Kg/day is preferably administered, in which case the concentration of compound () is about 1-500 ppm, especially 2-500 ppm.
It is best to add it to feed at a concentration of 200ppm. In addition, for the purpose of treating swine dysentery, it is preferable to administer the compound () at about 0.1 to 25 mg/Kg/day, in this case about 2 to 500 ppm, especially about 2.5 mg/kg/day.
It is best to add it to feed at a concentration of ~200ppm. On the other hand, for the purpose of improving the productivity of pigs, it is preferable to administer the compound () as about 0.025 to 10 mg/Kg/day, and in this case, it should be added to the feed at about 0.5 to 200 ppm, especially about 1 to 100 ppm. It is better. The toxicity of compound () to animals is extremely low; for example, in an acute toxicity test using mice,
The LD 50 by oral administration was 14-
10000 for both propionate and lankacidin A
mg/Kg or more, the LD 50 by intraperitoneal administration is 8000 to 10000 mg/Kg for lancasidin A;
For C14-propionate, it was more than 10,000 mg/Kg, and for lankacidin C, it was 4,500 mg/Kg. This not only indicates that it is highly safe for humans during manufacturing and distribution, but also has a wide tolerance to the target animals, so when administered by mixing it with feed, for example, there is a considerable degree of non-uniformity in the mixture. This shows that it is possible to guarantee the safety of target animals even if Next, the present invention will be explained in more detail using experimental examples and examples, but it goes without saying that these do not limit the scope of the present invention. Experimental Example 1 An in vitro antibacterial activity test against Treponema hyodei senteriae, the causative agent of swine dysentery, was conducted using Kashiwazaki et al.'s ``Method for measuring drug susceptibility of Treponema hiodei senteriae'' (Summary of the 82nd Japanese Veterinary Medical Association Conference)
Page 101: Measured according to 1978). As shown in Table 1, lankacidin C showed strong antibacterial activity, but all other antibiotics used for comparison were ineffective.

[Table] Experimental Example 8 In this experimental example, medication was administered at the same time as the onset of swine dysentery.
It was carried out under conditions of so-called therapeutic medication. The infection method was the same as in Experimental Example 5, and five animals that developed symptoms on the same day (6th day) after infection were used in the test, and feed containing 50 ppm of lankacidin C was fed at the same time as the onset of symptoms. The result is the 8th
As shown in the table, the mucus and bloody diarrhea stopped in all cases the day after administration, and the stool changed from soft to normal, and the number of bacteria in the stool fell below the detection limit (10 2 CFU/g) on the second day. An autopsy performed on the 15th day after onset (9th day of drug withdrawal) revealed no lesions in the large intestine and no bacteria were detected.

We tested 40 5-month-old Landrace pigs in 5 litters.
Five groups were established, each consisting of 8 animals (4 males, 4 females). The concentrations of lankacidin C added to the feed were 0 (control), 1, 2.5, 5, and 10 ppm, and from the start
For 5 months, add to artificial milk B without adding antibacterial agents until the age of 4 months and mix with pig meat production ability test feed (also without addition of antibacterial agents) from 4 months of age to 6 months of age (completed). Each group was fed continuously over a period of time. The results are summarized in Table 10. As the concentration of lankacidin C increases, growth of pigs is promoted, feed utilization is improved, and compound ()
is useful for improving pig productivity even under normal breeding conditions.
