Impact of Cold Stress on Haematological and Biochemical parameters of Yemeni toad (Bufo Tihamicus)

摘要

ABSTRACT Changes of some haematological and biochemical parameters of 30 Yemeni toad (Bufo Tihamicus) were studied after one and two hours of cold stress. The haematological parameters showed an increase after one and two hours in compare to control. The RBC count increased after one and two hours as (1.44 and 1.65) x 106 cells/mm3, hemoglobin amount (Hb) as ( 8.6 and 9.52) g/dl, hematocrit value (HCT) as ( 24.6 and 27.88 %), mean cell volume (MCV) as (171.08 and 168.32 .
