| Abstract | ||
| This study Was designed to evaluate the effect of thermal heat on the Peripheral plasma concentration hormones oestradiol, progesterone, follicle stimulating hormones (FSH) and luteinizing hormone ((LH). These hormones were measured by a competive protein binding assay in six Iraqi buffaloes Bubalus bubalis at un prop irate stages of estrus cycle during warm season (March& April) and hot season (July& August). It is interest to note that levels of oestradiole and progesterone in the warm season were significantly higher( p<0.05) than those measured at the hot season, while there is no significant effects of the concentration of FSH during two different season, also our study showed an elevation of the concentration of LH in warm season compared with hot season but the effectiveness were not significant. The present study also showed none significant elevation of FSH concentration during hot season compared with warm season. | ||
