Test of preparations flightblock and Damit superforte in vivo

Abstract

The purpose of our research was to study the acaricidal activity of the preparations of Flyblock and Damit superforte in the of cattle scabies. Flyblock contains as active ingredient cyfluthrin 10 mg/ml. In the composition of Damit superforte includes a formamide compound and a synthetic pyrethroid of the new generation at 50 mg/ml. For the setting of the experiments 21 animals with clinical signs of scabies were selected. The animals were divided into 3 groups of 7 animals each. The animals of the 1st group were treated with Flyblock, the animals of the 2nd group were treated with Damit superforte, the animals of the 3rg group served as controls and did not undergo treatment. The cows were treated with the preparations twice with an interval of 7 days. From each animal scrapings were taken before the first and repeated treatments, and also 7 days after re-treatment. The material was taken from 1 cm² of skin in 3 places in the lesion area of each animal. As a result of the studies it was found that the preparation Fly-block possesses 71% efficiency in single treatment and 100% efficiency in a double treatment of cattle with scabies with an interval of 7 days by a rubbing method. In this case the decrease in the number of alive ectoparasites in the test material 7 days after the first treatment was 84.5%. The preparation Damit superforte possesses 100% efficiency in the single treatment case by a method of rubbing of cattle with scabies.
