To DETERMINE changes in the vaginal temperature, oxidants-antioxidants, and ovarianhormones to new, blank, and used CIDR in Dromedary camels, Ten healthy, non-pregnantdromedary camels of age (6-12) years were divided equally into two groups. The first group wasinserted previously used-CIDR (uCIDR)-data logger for eleven days. The second group was inserteda new-CIDR (CIDR)-data logger for 8 days. All ciders were removed for 5 days (control-rest interval)and then re-inserted after washing and cleaning for another 11 days (R-uCIDR, R-CIDR). Bloodsamples were collected and sera were used to measure estradiol (E2), progesterone (P4), totalantioxidants capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), glutathione reduced(GSH), and catalase (CAT). Results showed increased (P<0.0001) vaginal temperature after re-inserting CIDR. The control rest intervals had the lowest (P<0.0001) P4 and GSH while E2 and MDAreached their highest levels. CIDR and R-CIDR insertions indicated higher (P<0.0001) vaginaltemperature, P4, E2, with lower MDA and NO compared to uCIDR. The use of the univariate generallinear model (Intercept + 2 treatment +11 Days CIDR + 24 Hour + 5 animals) revealed that vaginaltemperature is influenced (P<0.0001) by treatment, Days, hour, Treatment ×Day, Treatment ×hour.Vaginal temperature correlated (P<0.0001) with ambient temperature of uCIDR (r=0.37); R-uCIDRand CIDR (r=0.28); and R-CIDR (r=0.40). In conclusion ambient temperature, day during CIDR,hour of the day, and type of CIDR affects vaginal temperature. Ovarian hormones, oxidants, andantioxidants vary according to the type of CIDR, days of insertion and after removal.
