Abbas MT, Hatif SA., Effect of season and pregnancy, lambing, estrus and suckling on circulating prolactin, estradiol and melatonin levels in 15 gazelles (Subgutturosa mareka), Onl J Vet Res., 22 (8):692-691, 2018. Jugular blood was taken for plasma prolactin, estradiol and melatonin ELISA assays during pregnancy, lambing, estrus and suckling in 15 gazelles (Subgutturosa mareka) from March to November 2017 (Iraq). Prolactin levels were highest during Summer and lowest in Spring (P < 0.01), melatonin highest in Autumn but lowest in Spring (P<0.01) and estradiol highest in September (P < 0.01). Plasma prolactin at lambing was 3.570 0.18, suckling 3.343 0.17 (P < 0.01), pregnancy 0.420 0.02 and estrus 0.846 0.07ng/ml, plasma melatonin 7.16 0.26, 8.89 0.43, 12.91 0.35 and 14.47 0.17 pg/ml being higher (P < 0.01) at estrus and lowest during pregnancy. Plasma estradiol was higher (P < 0.01) at estrus (128.52 7.19) and lower in pregnancy (108.87 6.62) and lambing (106.87 4.89pg/ml). We found correlations (P<0.05) between plasma prolactin and melatonin during pregnancy and estrus, and between prolactin and estradiol and melatonin and estradiol at suckling.
