Studies on the oestrous cycle of camel (camelus dromedarius)‎

الملخص EN

The aim of this study was to investigate the oestrous cycle of the Arabian came].

£ight female camels (Majaheem) were used.

Daily blood samples were collected for 60 days to measure Oestradiol -17B (E2) and progesterone (P4) levels using radioimmunoassays.

The duration ofthe follicular wave cycle ranged from 25-30 days and the length of oestrous from 5-7 days.

p4 levels were low (<3.2 nmol/1) throughout the cycle, while E2 levels were high during oestrous.

The corpus luteum was therefore not present during the natural cycle suggesting that Arabian camels experienced induced ovulation.
