| Popis: | Forty eight (48) anestrus lactating Iraqi ewes aged between 2-4 years were undertaken 40 days postpartum in Babylon province (Technical institute in Al-Mussaib). Ewes were randomly divided into 4 equal groups according to type of treatment implemented. Group 1 (G1) were treated with vaginal sponges impregnated with 60 mg Medroxy Progesterone acetate for 10 days. Immediately after sponge removal, each ewe was injected IM. with 500 IU. Equine choriogonadotropines. Ewes of G2 were treated with Medroxy Progesterone acetate and Equine choriogonadotropines as mentioned above in addition n to 10 mg bromocriptine/day orally for 10 successive days at the same time of sponges insertion. Animals of G3 were treated with Medroxy Progesterone acetate and Equine choriogonadotropines in addition to 20 mg bromocriptine/day orally for 10 days. Ewes of G4 were treated with Medroxy Progesterone acetate and Equine choriogonadotropines in addition to 30 mg bromocriptine /day orally for 10 days. All ewes were mixed free with 5 fertile rams for 7 days after hormonal treatment to detect estrus and natural mating. Results showed that the duration of response to treatment was significantly longer P |
