Annual Change of the Hematological Parameters in Female White Goats

Abstract

In this study, hematological parameters changes in female goats were observed. It has been shown that a decrease in the level of erythrocyte (RBC), Hematocric (Htc) and Hemoglobin (Hb) in higher temperature conditions was statistically different from an increase in the level of these characters in lower temperature conditions (P<0.01). Monthly changes in level of Leukocyte, lymphocyte, granulocyte and monocyte were statistically different (P<0.01).  Moreover, increase in level of WBC, granulocyte and monocyte in higher temperatures and a decrease in level of lymphocyte were detected. The effects of seasonal changes (temperature) on Thrombocyte (THR) values were significant and reached higher measurements during warmer months.  Reductions in the level of RBC, Htc, Hb and THR values in months with a higher temperature can be considered as a result of the elevations of blood plasma volume. Rise in values of WBC, Gra and Mon in months with a higher temperature might be related with immunologic regulation and effects of physiological periods.
