The study was conducted on 30 dairy cows of Friesian – Holstein breed, during 2010 from April to July, suffering from ovarian follicular cyst. The animals were presented in Al-fyhaa station, Gbala, Musieb-Babelon. The ages of animals ranged from 4-8 years. The animals were divided in three groups. The first group (N=12)were treated with 0.5 mg of GnRH i.m. The second group (N=10) were treated with 125 mg progesterone i.m. followed after 7days given 22.5 mg of PGF2α i.m. The third group (N=8) were treated with 3000 I.U. of HCG i.m. Rectal palpation was the criteria of diagnosis. All animals were subjected to rectal palpation after 14 days post treatment. Positive results were considered when the cyst subsides while negative results when there is no change in the size of the cyst.
The results showed that the treatment with GnRH give the best results with efficacy of 84% (1012). While the treated groups with progesterone+PGF2 and HCG showed an efficacy of 40% (414) and 50% (510) respectively. There was significant difference (P<0.05) between GnRH treated group and other treated groups. It was concluded that the GnRH gives the best results in treatment of follicular cystic ovaries in dairy cows.

The objective of this study was to compare between two methods of estrus synchronization (progestin-impregnated vaginal sponges and intra-muscular (i.m) progesterone analogue injection ) and its influence on estrus occurance and pregnancy rate in Awassi ewes . Twenty eight ewes were equally divided into two groups ( A and B ) . Vaginal sponges impregnated with 20 mg of fluorogestone acetate ( FGA ) were used to synchronize the estrus in group A-ewes . The animals in group B were i.m. injected with 7 mg/day of progesterone analogue for 12 days . Post – withdrwal of sponges and at the end of progesterone injection , 500 IU of equine chorionic gonadotropin ( eCG ) were injected to both groups of ewes . The ewes were naturally mated with fertile rams ( 1 ram/group ) . the rams were left for 48 hrs. to ensure a good conception rate . The differences between two groups in estrus signs appearance lacked significance . On the other hand , group A – ewes exhibited higher ( P < 0.05 ) pregnancy rate than group B ( 78 VS 50% ) . In conclusion , estrus synchronization of ewes using vaginal sponges impregnated with FGA in conjuction with eCG treatment is effective and low-cost regime that achieved agood reproductive performance .
