Ecologically safe composition to protect Animals from parasitic mites.

The publication discusses the results of using a composition based on pine resin against parasitic animal mites. Both the toxicity and repellency of the developed composition against parasitic mites, as well as the possibility of using the resulting preparation, based on turpentine oil, as an alternative to chemical acaricidal compounds, are considered. The effectiveness of the developed composition was studied both in laboratory and in real conditions. When contaminating, under laboratory conditions, hungry individuals, their 100% death was observed after 96 hours. In real conditions, the number of dead mites that fell from the skin after treatment of animals was recorded. It has been established that hungry adult ticks die completely within 3-4 days, and well-fed individuals - after 4- 5 days. The clinical condition of the cattle in the experiment was within the normal range, milk yields did not decrease. Parasitic mites do not settle on the body of an animal for 25-28 days when the skin of animals is treated with a working solution of a composite preparation. Imported acaricides on the market protect animals from attack by parasitic mites for only 12-15 days, which is probably due to the repellent properties of turpentine oil and prolonged acaricidal action of the composite preparation. Clinical, hematological, biochemical, as well as macro- and micromorphological studies (3 hours after applying the composite preparation to the skin of experimental rabbit animals) showed a slight decrease in the activity of blood cholinesterase, hemoglobin, as well as the number of erythrocytes and leukocytes. 72 hours after contamination, all indicators are restored to their original level, without signs of intoxication. 1 hour after the treatment of rabbits with a composite preparation according to the “rubbing into the skin” principle, moderate capillary hyperemia and perivascular infiltration were observed on the skin and regional lymph nodes. 6 hours after rubbing the drug into the skin, these changes are no longer observed, which indicates that these changes are not the result of the toxicity of the drug or its accumulation in the skin. Consequently, composite drug prepared on the basis of gum turpentine fully complies with modern requirements for veterinary preparations. Tab. 1, Ref. 14.
