This is a unique mechanism that occupies a dominant position in ensuring tissue respiration and stability of metabolic processes in the body. Based on research and analysis of publications, it can be argued that changes in erythrocytopoiesis indicate a pathological condition, which in the early stages of helminthiasis occurs without pronounced clinical signs. It is known that the nematode – Amidostomum anseris – hematophagous. The condition of erythrocytopoiesis is most studied in cattle and carnivores. In Ukraine, not enough attention is paid to the study of morphological parameters in geese. Therefore, in order to determine the effect of amidost on the morphological parameters of sick goslings, an experimental group of birds aged 1.5 months, as well as a control group (eight heads in each) was formed. The work was performed in the conditions of individual peasant farms in the village of Decembrists of Myrhorod district of the Poltava region. Morphological parameters were studied according to generally accepted methods. The article summarizes the results of the experiment on the effect of amidostom on the performance of infested goslings of the large gray breed. It was found that parasitism in waterfowl species A. anseris led to changes in the overall analysis of the blood of geese: a decrease in hemoglobin by 8.39, the number of erythrocytes – 13.46 %, a significant increase in the number of leukocytes to 24.44 G/l. At the same time, a morphological study of the shaped elements of the bird's blood with a differential calculation of the leukocyte formula was performed. There was a decrease in the number of segmental neutrophils (22.0 ± 0.57) compared with the control group (26.5 ± 1.45) due to lymphocytes and monocytes, which, in our opinion, is associated with the adaptation of the organism to parasitism of nematodes. The results of morphological studies of the blood of infested goslings indicate significant changes in their body and may indicate activation of the cellular immune system. ER -
