Special experimental experiments were conducted by infecting sheep with ixodid ticks. For the experiments, 3 groups of 5 sheep were formed. Of the sheep in groups 1, 2 and 3 selected for our experiments, the sheep of groups 2-3 were of great importance and were specially selected. Sheep taken for the experiment and control from the sheep infected with ectoparasites of group 1 were used for special experimental experiments. It was determined that within 30 days, the weight of 1 sheep infected with ectoparasites, in particular ixodidosis, decreased by 2.700 kg, and the daily rate by 90 g. It was found that the weight productivity of the sheep in the control group increased by 1,800 kg per head. The daily rate increased by 60 gr.
