Hematological parameters at hens of different age groups in capillariasic invasion

Abstract

The results of experimental studies to determine the impact of helminths of genus Capillaria on hematological parameters of sick chickens of different ages (replacement young chickens of 9–17 week old and hens of productive phases) were presented. It is established that the changes in the blood of young chickens, which infested by capillaries, characterized by a significant (p<0,01) decrease in the number of erythrocytes, hemoglobin, and an increase in the number of leukocytes at the cost eosinophils, which leads to more severe disease than in the adult birds.

In hens of productive phases at capillariasic invasion we detected insignificant (p<0,05), leukocytosis and eosinophilia.
