One of the most important aspects of insemination in camelidae is its timing in relation to ovulation.
The interval from mating to ovulation is not precisely known in camels although based on clinical observations most authors have suggested it is between 32 and 40 h after mating in dromedaries (Marie and Anouassi,1986,1987;Tibary and Anouassi,1996) and 30-35 h in Bactrian camels (Xuet al., 1985). However, in a more recent study where the ovaries of dromedary camels were scanned at regular 2 h intervals from 20 to 36 h after induction of ovulation with 20 µg GnRH (i.v.), the majority of camels ovulated between 26 and 30 h after injection (Skidmore and Adams,unpublished data). This more rapid ovulatory response could be because the GnRH injected intravenously is absorbed more quickly by the pituitary thus causing a more rapid LH pre-ovulatory peak.
