Abstract
This study was carried out at the sheep farm of the Animal resources Department, College of Agriculture, University of Al-Anbar, during the period of 5/11/2012 until 5/5/2013 on 24 Ewes with age 2-4 years and with average weight of 45-50 k.g. All ewes were diagnosed by using the real-time Ultrasonography to make sure there is no pregnancy among the ewes before the beginning experiment. The Ewes were divided randomly into four groups 6 ewes for each group. The first group was insert CIDR to 12 days and injection of 500 IU eCG in muscular at CIDR Removal, The second group ewes treated by inserting CIDR for 12 days as well as the injection progesterone hormone before one day to CIDR removal (in day 11) in muscular 25 mg/head, and the third group insert vaginal sponge to 12 days and injection eCG 500 IU in muscular at vaginal sponge removal, The fourth groups ewes were injected with distilled water and considered as control group. The ewes were inseminated by rams at the end of the hormonal program for three days and the rams were circulated in the cages to avoid the ram effect. The blood sample were taken from the Jugular vein before one day to insert treatment and day 1, 3, 5, 7, 9, 11, 12, 13 to experiment for measuring changes in reproductive performance and blood picture during the period of treatment. The result of study show no significant different in time of the show estrus between the four groups and improves the hormonal treatments groups significantly compared with control group in estrus rate it was (100, 83.33, 83.33, 16.66)% respectively, pregnancy rate was (100, 83.33, 66.66, 0)% respectively and parturition rate was (83.33, 66.66, 66.66, 0)% respectively with improving first group on another group. The laboratory analysis through hormonal treatment the result shows improved treatment group compared with control in W.B.C in day 9 without significant difference between the treatment groups, and result show no significant differences between treatment groups and control in H.B. and P.C.V. in all time withdrawal
