ESTROGEN LEVEL DETERMINATION DURING ESTRUS CYCLE OF CAPRI . IBEX FEMALES AND ITS EFFECT ON WHITE BLOOD CELL

Abstract

This study was carried on (7) females Caper . ibex, age between 3 – 4 years at Baghdad Zoo /Al – Zawrra park within reproductive season .The body weight between 25 – 30 kg .All the animals were put under environmental conditions .The aim of this study was to measure the blood estrogen level during the estrous cycle (proestrous , estrous and diestrous) and the effect on the differential white blood cell count . Results of this study showed significant differences during estrous cycle period about serum estrogens concentration in (P<0.05) ,which recorded the highest level at the first day of the estrous period (7.2600 ng/ml) ,while the lowest level (0.5720 ng/ml) was at 19th day of diestrous period . The differential white blood cell count showed no significant differences between the estrous cycle period about neutrophils , but there were significant differences between 3rd day of estrous period (50.500) and 2nd day of proestrous period . while there were no significant differences recorded in esnophils ,basophiles and monocyts during estrous cycle period also between cycles day . lymphocytes showed no significant differences between proestrous period (60.000) and estrous and diestrous period (53.538 and 57.019) also between estrous cycle day . It may be concluded that , estrogens hormones affected on the neutrophils and lymphocytes ,but there was no effect on esnophils ,basophiles and monocyts .
