Orexin A (OXA) and orexin B (OXB) are neuropeptides synthesized mainly in the lateral hypothalamus, which are involved in the control of various physiological functions such as energy homeostasis, sleep, wakefulness and feeding behavior. The present study analyzes orexins A and B levels in the porcine plasma during the estrous cycle. The highest plasma concentrations of orexin A were observed on days 2-3 of the estrous cycle (p<0.05 relative to days 10-12 and 14-16) and the lowest (p<0.05) on days 14-16. The highest orexin B levels in the blood plasma were noted on days 17-19 (p<0.05 vs. days 14-16). We demonstrated the presence of OXA and OXB in porcine blood plasma and the impact of the phase of the estrous cycle on the observed changes in plasma orexin levels.
