The present invention relates to an antiviral agent for animals, more specifically, the general formula () The present invention relates to an antiviral agent for animals containing one or more compounds represented by the formula (wherein R 1 , R 2 , R 3 and R 4 represent lower alkyl groups) as an active ingredient. Viral diseases in animals include influenza, swine fever, distemper, Newcastle disease, foot-and-mouth disease, Maretske's disease, Japanese encephalitis, rabies,
Known causes include infectious anemia in horses, viral diarrhea in cattle, and infectious gastroenteritis in pigs. These diseases are highly contagious, and once they occur, they cause a lot of damage. For example, when infectious gastroenteritis occurs in pigs,
Due to the intensive breeding system, all pigs of all ages are affected by the disease, and it is not uncommon for piglets, especially those just born, to be wiped out. Mortality is low in older pigs, but they suffer from severe diarrhea and a marked decline in growth. In sows, it causes diarrhea and cessation of lactation, and has a negative impact on suckling piglets. As a result of various studies on antiviral agents for animals, the present inventors found that the compound represented by the above general formula () is excellent as an antiviral agent for animals. The present invention was completed based on this knowledge. The compound represented by the general formula () used in the present invention is, for example,

[Table] The acute oral toxicity LD 50 value of the above compound is 25,000 mg/Kg or more for mice, 2,500 mg/Kg or more for rats, and 2,000 mg/Kg or more for quails, indicating extremely low toxicity and very high safety. The compound represented by the above general formula () obtained by the fermentation method is usually a mixture containing compounds No. 3 to No. 5 as main components, and this mixture is called a polynactin complex (common name). There is. The dosage of the compound represented by the above general formula () is preferably 0.01 to 50 mg/kg of livestock body weight per day. The antiviral agent for animals of the present invention can be prepared by adding the compound represented by the general formula () as it is or by mixing it with a physiologically harmless solid or liquid carrier to prepare a concentrate and add it to animal feed or drinking water. preferable. Examples of solid carriers used here include wheat flour, soybean flour, corn starch, defatted rice bran, calcium carbonate, talc, kaolin, chalk, diatomaceous earth, etc., and liquid carriers include water, physiological saline, etc. can give. In addition, auxiliary agents or additives such as emulsifiers, dispersants, suspending agents, and wetting agents may be used as necessary. Among them, the active ingredient compound powder of the present invention can be used as feed.
It is practical and economical to mix the compound at a ratio of 0.5 to 500 ppm and continuously administer it to animals. Furthermore, the antiviral agent for animals of the present invention may be directly administered in the form of solid preparations such as tablets, capsules, granules, pellets, and boluses, or liquid preparations. Note that there is no problem in adding other drugs to the antiviral agent for animals of the present invention. The excellent effects of the antiviral agent for animals of the present invention will be explained below using experimental examples using a polynactin complex and each active ingredient. Experimental example 1 (1) Experimental method Using porcine infectious gastroenteritis virus,
The antiviral effect in vitro was investigated. Each polynactin protein component was dissolved in the culture medium 24 hours before virus adsorption to piglet kidney tissue culture cells, so that each polynactin component was present in the culture medium both during and after adsorption. The drug concentration was 0.1 μg/ml. The amount of virus was measured on the 0th, 1st, 2nd, and 3rd day after virus adsorption by a dilution method using the cytopathic effect as an index. (2) Results The results are shown in Table 1. Without the addition of drugs, the virus reached its maximum proliferation within one day. In contrast, virus proliferation was clearly suppressed in the presence of each polynactin component.

[Table] Experimental example 2 (1) LH castrated pigs weighing approximately 15 kg were fed feed supplemented with polynactin complex one week before inoculation with infectious gastroenteritis virus, and continued to be fed the same feed after inoculation with virus. The animals were observed for one week to see if they developed infectious gastroenteritis. The virus was orally inoculated at 10 3 ID 50 per animal. The components of the polynactin complex are dinactin: trinactin: tetranactin (1:1:8), and the amounts added are 1 ppm, 10 ppm,
There were five levels: 100ppm, 1000ppm, and no additives. Five pigs were used in each section. As an indicator of infectious gastroenteritis, diarrhea was classified into four stages: normal stool, soft stool, muddy stool, and watery stool. (2) Experimental results The results are shown in Table 2. From the second day after inoculation with the infectious gastroenteritis virus, diarrhea began to occur in the non-additive group. In all groups to which the polynactin complex was added, the occurrence of diarrhea was small and the severity was mild, and the clear preventive effect of the polynactin complex against infectious gastroenteritis was observed.

[Table] Note: Diarrhea status represents the most severe case for each individual.
Experimental Example 3 Feed containing nonactin, monactin, dinactin, trinactin, and tetranactin at a concentration of 50 ppm was started being fed to LH castrated pigs weighing approximately 15 kg one week before inoculation with infectious gastroenteritis virus. After inoculation with the virus, each drug-added feed was continued to be fed for one week, and the presence or absence of infectious gastroenteritis was observed. The virus was orally inoculated at 10 3 ID 50 per animal. The number of animals was three in each ward. Diarrhea was observed in the same manner as in Experimental Example 2. Experimental Results The results are shown in Table 3. Nonactin, Monactin,
In the groups treated with zinactin, trinactin, and tetranactin, no infectious gastroenteritis occurred, and even if it did occur, it was mild, and the preventive effects of each drug against infectious gastroenteritis were observed.
