Sažetak
Blood samples were collected from cycling Sahiwal cows at -2,-1, 0, +1, and +2 days of the estrus cycle and analyzed for plasma levels of Nitric oxide (NO) and Nitric Oxide Synthase (NOS) vis a vis ovarian steroidal hormones viz. estradiol-17β and progesterone. The results revealed a gradual increase in NO, NOS and Estradiol-17β levels from day -2 and they peaked at the day of estrus, followed by a steep fall up to day +2. The values of NO, NOS and estradiol-17β ranged between 7.93 to 18.92 μM/L, 0.39 to 0.95 U/L and 5.46 to 20.16 pg/mL, respectively. The levels of progesterone ranged from 0.15 to 0.71 ng/mL and showed a significant decline from day -2 to the day of estrus and then remained statistically parallel. In addition, levels of estradiol-17β exhibited a highly significant (P<0.01) association with levels of NO and NOS. The present study generated data on NO, NOS, estradiol-17β and progesterone at and around estrus in cows, which is of practical importance for clinical and experimental interpretation.
