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

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 .
