Testing of the supramolecular complex of ivermectin Aniverm-2.0% against gastro-intestinal strongylatosis of marals, sika deer and roe deer

The purpose of the research is to test the supramolecular complex of ivermectin Aniverm-2.0% by free feeding of the drug mixed with concentrated feed against gastro-intestinal strongylatosis of the deer.Materials and methods. The test of the supramolecular complex of ivermectin Aniverm-2.0% against gastro-intestinal strongylatosis of semi-wild animals was carried out from November 2023 to April 2024 in the reserve of the country residence of the head of the Chechen Republic, where more than 200 marals, sika deer and roe deer were kept. 40 fresh fecal samples were collected from the ground in December 2023. The fecal samples were examined in the biology laboratory of the Ibragimov Integrated Research Institute of the Russian Academy of Sciences by the Fülleborn flotation method using a saturated sodium chloride solution and the method of successive washes to detect elaphostrongyl larvae. Aniverm-2.0% was fed at a dose of 0.3 mg/kg mixed with concentrated feed by the group method; evenly poured into 4 feeders for 200 deer. The efficacy of the drug was taken into account by the "critical test" after 10 days and 4 months after deworming.Results and discussion. In the feces of deer, strongylata eggs were found in 23 out of 40 samples (EI = 57.5%) with an average of 88.9±2.74 egg sp. detected in 1 g of feces. Elaphostrongyl larvae were not detected. Dicrocoelium spp. eggs were found in 8 samples. After deworming of marals, red deer and roe deer with Aniverm-2.0% at a dose of 0.3 mg/kg by active ingredient (0.15 mg/kg by the drug) by the group method mixed with compound feed, strongylata eggs of the digestive tract were not found in the feces after 10 days and for 4 months after treatment. 100% therapeutic and prophylactic efficacy of the drug was established. The animals willingly ate the drug with food, no side effects were noted after administration of the drug.
