Abstract EN

This study aimed to evaluate the effect of dexamethasone and gonadotropin releasing hormone (GnRH) on improvement of the fertility of Baladi goats.

To accomplish this study, twenty does were synchronized for estrus using PGF-2α agonist.

Then, they were divided into four groups randomly (5/ each).

Group-I was injected with dexamethasone, while, group-II was injected by three doses of gonadotropin releasing hormone (GnRH).

Group-III, was injected by dexamethasone and GnRH, while group-IV was injected with saline to be used as control group.

The fertile bucks were allowed to mount the does for fertilization.

Ovarian response to the treatment and diagnosis of pregnancy were monitored using ultrasonography.

Results revealed that compared to control group, all the treatment protocols have a significant intensifying and improving effect on the appearance of signs of estrous, the day of mount, day of pro-estrus, day of ovulation and day of mature corpus luteum formation.

However, the treatment with dexamethasone seems to have more effect over the other treatment protocols.

Also, the number of the detected mature corpora lutei was significantly increased upon application of the treatment protocols as compared to control group but this effect was more obvious in group I.

Finally, the treatment protocols tend to have no significant effect on the number of the formed mature follicles, weights of feti at birth or their weights after 60 days, on the other hand the treatments protocols has proved to decrease the percent of fetal losses when compared to control group.
