The objective of the study was to investigate the dependence of post-treatment invasion on preparations used in pig mange and sheep intestinal strongylatoses. Our trials were made to compare the effect of 6 preparations in swine sarcoptosis: Ephoksen, Ivomec, Ectopor, Sebacil Pour-on, Bensilate and Saroxen-E. According to the results, reinvasions were formed up to 6...8 months after treatments. The invasion level of control group fluctuated between 98.5...102.3 per cent compared with initial density. The results of our tests show that the most effective preparations were Ivomec and Saroxen-E. The mixture of 3 antiparasitic substances had a synergistic effect for mange mites. A great improvement was noticed after treatment procedures with Sebacil Por-on and Ectopor. Our data show that Ivomec and Saroxen-E prolonged the period before invasions up to 10 months. To avoid the reinvasions on farm, repeated treatment of pigs is needed. According to our data, at 10 and 20 days after dehelmintization the mean extent of invasion was 2 plus minus 2 per cent and 4 plus minus 4 per cent respectively. Significant differences in sheep invasion level after treatment procedures with different anthelmintics were not noticed. After 30, 60 and 90 days the mean extent of invasion was 22plus minus 6 per cent, 34 plus minus 7 per cent and 53 plus minus 7 per cent. At 30, 60 and 90 days after treatment with Ivomec the extent of invasion was significantly lower compared with other groups
