  Futtermittel mit anticoccidischer Wirksamkeit 
Die Erfindung betrifft ein Futtermittel mit anticoccidischer Wirkung, das als Wirkstoffe neue Ester von   6, 7-Alkoxy-4-hydroxy-3-chinolmcarbonsäuren   enthält. 



   Coccidiose, eine weit verbreitete und vom wirtschaftlichen Standpunkt bedeutungsvolle Geflügelkrankheit, wird durch eine Vielfalt von Coccidien einschliesslich Eimeria tenella, Eimeria acervulina und Eimeria necatrix hervorgerufen. Die erfindungsgemäss verwendeten neuen Verbindungen sind gegen- über diesen Coccidien hochwirksam. Werden sie einem Futter mit ausgeglichenem Nährstoffgehalt in einer Menge von ungefähr 0, 006 bis ungefähr   0, 1 Gew. J1/0   zugesetzt und damit an mit Coccidiose infizierte Hühner verfüttert, wird die Sterblichkeit oder Kränklichkeit, die gewöhnlich die Folge von Coccidiosen sind, überwunden und ein günstiger Effekt auf das Wachstum und den Allgemeinzustand der Vögel ausgeübt. 



   Die wirksamen Verbindungen sind niedere Alkylester der 6,   7-Di-nied. -Alkoxy-4-hydroxy-3-chino-   lincarbonsäure, mit der allgemeinen Formel 
 EMI1.1 
 worin   RundR einen   niedrigen Alkylrest mit 2-4 Kohlenstoffatomen und   R,   einen niedrigen Alkylrest bedeutet. 



   Die Herstellung dieser neuen Verbindungen kann nach einem an anderer Stelle erstatteten Vorschlag dadurch erfolgen, dass man ein entsprechendes   1, 2-Di-niedrig- alkoxy-4-nitrobenzol   reduziert, die Lösung des reduzierten Produktes in Gegenwart eines Wärmeregulierungsmittels,   z. B.   einer eutektischen Mischung von Diphenyläther und Diphenyl, mit einem entsprechenden   Di-niedrig- alkyl-niedrig- alkoxy-   methylenmalonat versetzt und die Mischung erhitzt. 



   Beispiele für bevorzugt in den erfindungsgemässen Futtermitteln verwendete Ester sind die Methyloder Äthylester der   1, 2-Diäthoxy-, 1, 2-Dipropoxy-, 1, 2-Dibutoxy- oderl, 2-Diisopropoxy-4-hydroxy-   -   chinolincarbonsäure.   



   Vorzugsweise enthält das Futtermittel   0,     02-0, 1 Gew.-lo   des Esters. 



   Die Verarbeitung der neuen Verbindungen zu einer Form, die bequeme Verabreichung gestattet, erfolgt in einfacher Weise durch Vermischen mit dem Futter wie oben angegeben. Wenn gewünscht, können die Verbindungen auch zu Tabletten, Gelatinekapseln, Suspensionen od. ähnl. Zubereitungen verarbeitet werden, die noch geeignete Trägerstoffe und sonstige in der Pharmazie übliche Zusatzstoffe enthalten.

  Feed with anticoccidic activity
The invention relates to a feed with an anticoccidic effect which contains new esters of 6, 7-alkoxy-4-hydroxy-3-quinolmcarboxylic acids as active ingredients.



   Coccidiosis, a widespread and economically significant poultry disease, is caused by a variety of coccidia including Eimeria tenella, Eimeria acervulina, and Eimeria necatrix. The new compounds used according to the invention are highly effective against these coccidia. When added to a balanced nutrient feed in an amount of about 0.006 to about 0.1 percent by weight and fed to chickens infected with coccidiosis, the mortality or sickness that usually results from coccidiosis is overcome and exerted a beneficial effect on the growth and general condition of the birds.



   The active compounds are lower alkyl esters of the 6, 7-di-lower. -Alkoxy-4-hydroxy-3-quino-lincarboxylic acid, with the general formula
 EMI1.1
 where RundR denotes a lower alkyl radical having 2-4 carbon atoms and R 1 denotes a lower alkyl radical.



   The preparation of these new compounds can be carried out according to a suggestion made elsewhere that one reduces a corresponding 1, 2-di-lower alkoxy-4-nitrobenzene, the solution of the reduced product in the presence of a thermoregulator, eg. B. a eutectic mixture of diphenyl ether and diphenyl, mixed with a corresponding di-lower alkyl-lower alkoxymethylene malonate and heated the mixture.



   Examples of esters preferably used in the feed according to the invention are the methyl or ethyl esters of 1,2-diethoxy-, 1,2-dipropoxy-, 1,2-dibutoxy- or 1,2-diisopropoxy-4-hydroxy- quinolinecarboxylic acid.



   The feed preferably contains 0.02-0.1% by weight of the ester.



   The processing of the new compounds into a form which permits convenient administration is carried out in a simple manner by mixing them with the feed as indicated above. If desired, the compounds can also form tablets, gelatin capsules, suspensions or the like. Preparations are processed which also contain suitable carriers and other additives customary in pharmacy.
