Abstract
Background:
The progesterone (PBP) hormone is responsible for maintaining pregnancy. By measuring its level, a single or twin pregnancy in deer can be diagnosed based on its blood PBP concentration.

Aim:
This study aimed to determine plasma blood PBP levels in Reem gazelles (Gazella subgutturosa marica).

Methods:
Thirteen pregnant females (G. subgutturosa marica) aged 2–4 years were used. The experiments were conducted from October 2021 to April 2022 in Babylon, Iraq. Jugular venipuncture was used to collect ten milliliters of EDTA-free blood samples. The samples were then centrifuged at 3,000 rpm for 10 minutes to separate the sera, which were then stored at −20°C in sterile test tubes for later analysis. The samples were then transferred to the central laboratory of the Faculty of Veterinary Medicine, Al-Qasim Green University. The electrochemiluminescence immunoassay, or “ECLIA,” was used to measure PBP levels in plasma. It is designed to be used with Elecsys and Cobas immunoassay analyzers.

Results:
The levels of PBP at 60 days of pregnant was (2.5375 ± 0.1267 ng/ml) less than those at days 90 (8.3 ± 0.151 ng/ml) and 120 days (11.51 ± 0.168 ng/ml) with significantly different (p < 0.01) between stages in the group of single fetuses. PBP concentrations within groups of twin-bearing animals at days (60, 90, and 120) were (5.06 ± 0.68, 12.5 ± 0.19, and 25.68 ± 1.297 ng/ml), respectively, with significantly different (p < 0.01). We found a significant difference (p < 0.05) between the two groups of pregnant females with single and twin fetus, and mean ± SE was (7.45 ± 0.7786, 14.41 ± 2.32 ng/ml), respectively.

Conclusion:
The current study describes how the content of PBP in the plasma blood of Reem gazelles (G. subgutturosa marica) can be utilized to predict whether a pregnancy is single or twin, as well as during various pregnancy periods.

Key words: Progesterone concentration, Reem gazelles, Single and twin fetus
