Abstract:
The study was conducted in the camel research center (CRC)( Shambat )to compare the effect of two hormonal protocols in ovulation induction in dromedary she- camel ( Camelus dromedarius ) during non breeding season. Number of eleven she – camels with varying age (6 – 17 years) and the average body weight from (250 – 350 kg ) and one male used for mating were selected for this experiment. The experimental animals were divided into three groups : group (A) control group ( N =3), group (B), (N = 3) intravenous injection with 1500 IU HCG 10 ml group ( c),
( N= 5) intravenous injection with 1000 IU of FOLLIGON (PMSG). Ovulation was observed in all experimental groups .The proportion of ovulation (4/5 , 2/3 , 1/3) 80%, 67 % 33% PMSG , control and HCG respectively. The confirmation of the ovulation was done by ultrasonographic examination .Results of the present study demonstrated that there is a highly significant difference between HCG ,PMSG and control group in induction of ovulation in dromedary she – camel during non breeding season (P≤ 0.05) also there is significant difference in number and size of ovarian follicle in left and right ovary (P≤ 0.05). In PMSG group ovulation occurred after 48 h post injection .In HCG group the ovulation occurred after 5 days post injection .
The study concluded that for ovulation to occur the size of the mature ovarian follicle should reach size of 0.7 – 3cm .
