| Abstract: | Mebendazole, administered at a dose of 30 mg active substance per 1 kg of feed, was found to have 100% effectiveness on Ascaris suum and Cambendazole, administered at a dose of 1.5 g per 1 kg of liver weight, showed the same effectiveness in the control of Ascaris suum and Oesophagostomum dentatum. The effectiveness of both drugs on Trichocephalus suis and Strongyloides ransomi was low. Mebendazole and Cambendazole can be recommended for mass dehelminthization of pigs in affected stocks. Helminthoovoscopical examination of sows and fattened pigs showed an 88.6% extensity of invasion in sows, and a 28.3% and 33.9% extensity in three- and five-month-old pigs, respectively. Coccidiosis was found in 51.4% of the sows and Balantidium coli had an occurrence rate of 80.7 to 98.2%. |
