Abstract
Invasive diseases of sheep are widespread worldwide, including in Kazakhstan. Recently, in the Akmola farms of Kazakhstan, there has been an increase in the spread of gastrointestinal diseases in sheep. The study aimed to assess the Prevalence (P) of sheep parasitosis in Northern Kazakhstan to develop effective prevention and control measures. Five-hundred and sixty-four sheep were studied in four rural districts and three economic entities located on the territory of the Tselinograd district of the Akmola for the presence of Ecto and endoparasites. The most frequent parasites were Nematoda such as Trichostrongylidae spp., Nematodirus spp., Skrjabinema ovis, Cestoda such as Moniezia spp., protozoa such as Eimeria spp., arthropods such as Melophagus ovinus, Bovicolaovis and Dermacentor and Wohlfarthia magnifica larvae. The P of Trichostrongylidae spp., Moniezia spp., Eimeria spp., Melophagus ovinus, Bovicola ovis, Dermacentor, and Wohlfarthia magnifica in small cattle of the study area were 77.1, 23.0, 55.4, 50.5, 62.6, 34.3 and 13.1%, respectively. For the first time, Skrjabinema ovis with P = 3.1% and an intensity of 150±22 eggs/g and Trichuris ovis with P = 4.7% and an intensity of 350±23 eggs/g were recorded in sheep in the Akmola region. For the successful development of industrial sheep breeding, as well as optimal animal husbandry in individual farms, it is necessary to provide animals with high-quality feed and maintenance, as well as take measures to reduce infectious and invasive diseases.
