Ovulation Induction in Dromedary She – camels by using two Different protocols During non Breeding Season

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 .
