Levels of some hormones in saliva and serum with special reference to ovarian status in cows

ABSTRACT

Blood and saliva samples were collected from 70 mature cows. The corresponding ovaries were collected after slaughtering to record the ovarian structures in each case. Then, the collected ovaries were classified into six groups, growing follicles, mature graafian follicles, mature corpus luteum, smooth inactive ovaries, graafian follicle cysts and luteal cysts. The levels of estradiol and progesterone were determined using ELISA technique. The results showed that the tested hormones reached considerable levels in saliva. Meanwhile, the hormonal profile in saliva followed the same pattern as in serum
