| Popis: | An experiment was conducted on Damascus does to characterise the oestrous cycle and activity of the corpus luteum and to determine normal progesterone patterns during different phases of the oestrous cycle using radioimmunoassay. Fifteen 2–5‐year‐old indigenous cycling Damascus does were used during the normal breeding season for two consecutive oestrous cycles. Average length of the oestrous cycles was 21.2 ± 1.5 days (range: 19–26 days), consisting of 2.9 + 0.8 days (2–5 days) where progesterone level was low, averaging 0.69 ± 0.85 nmol l‐1 (range: 0.00–3.08 nmol l‐1), followed by a sharp increase in progesterone secretion indicating presence of active corpora lutea which lasted an average of 15.3 ± 1.4 days (range: 13–20 days), with an average progesterone level of 13.41 nmol l‐1 (range: 3.26–27.98 nmol l‐1), followed by a sharp decline in progesterone level, indicating inactive corpora lutea, which lasted an average of 3.1 ± 0.6 days (range: 2–5 days), with an average progesterone level of 0.... |
