Abstract. The article presents some hematological and biochemical parameters of young cattle with mono- and mixed infections of dicrocoeliasis and fascioliasis. Infection of animals with helminths negatively affects blood parameters. Blood analysis plays an important role in detecting latent pathological processes, making a differential diagnosis, identifying complications, monitoring treatment effectiveness, and predicting the course of a disease. Therefore, it is relevant to study changes in blood parameters (such as the number of erythrocytes, leukocytes, and hemoglobin levels) depending on the development of a mono-infection caused by Dicrocoelium dendriticum (dicrocoeliasis) or Fasciola hepatica (fascioliasis) in the animals. The research was conducted on farms in the Babayurt district, located in the lowland zone of the Republic of Dagestan. The research material consisted of blood and feces obtained from young cattle, as well as internal organs of animals that were slaughtered out of necessity. For this purpose, certified methods of intravital diagnosis in veterinary parasitology (coproscopy, helminthoscopy, the native smear method, the Demidov and Fulleborn methods) were used, applied to fecal samples. As a result of the conducted studies, it was found that when young cattle are simultaneously infected with several species of helminths (mixed invasions), changes in blood composition are more pronounced than when infected with only one species (mono-infections). In young cattle infected with fascioliasis and dicrocoeliasis (in the form of mono- and mixed infections), a negative impact on the hematological and biochemical profiles is observed, manifested in the development of erythropenia, hypoglobinemia, leukocytosis, and dysproteinemia. The severity of trematode infection in calves correlated with the severity of changes in the leukocyte formula. Blood analysis showed a shift to the left, with an increase in the proportion of immature neutrophils. The most pronounced changes were observed in mixed infection with fascioliasis and dicrocoeliasis, where the number of immature neutrophils increased more than eightfold.
Keywords: large horned cattle, young stock, mono-infection, dicrocoeliasis, fascioliasis, parameter, hematology, biochemistry, differential white blood cell count.
