Induction of Parturition Using Bromocriptine, Prosolvin, Dexamethasone in Iraqi Goats

Thirty six pregnant Iraqi goats at gestation period ranged from 143-145 days were used in this study. The animals were divided randomly into 4 groups according to type of treatment given, G1 (9goats) given a single dose of 2.5 mg /Kg B.W bromocriptine IM, G2 (11 goats) given a single dose of prosolvin (PGF2α) 7.5 mg IM, G3 (8 goats) given a single dose of 16 mg dexamethasone IM, G4 (8 goats) given a single injection of D.W. and used as control. Results of table (1) showed that the response to bromocriptine and prosolvin were 77.7% and 81.8% and both were significant at p 0.01compare to 62% of dexamethasone. The induction period was recorded as 2.17±1.54 days and 2.29±1.14 days to prosolvin and dexamethasone compared to 4.36±2.29 days and 4.50±1.10 days of bromocriptine and controls both were significant at p 0.01. Table (2) number of goats delivered twins in bromocriptine group and prosolvin group were 57 and 68, both were significant at p 0.01compared to dexamethasone group and controls which were 35 and 48. The number of dead kids in all groups was insignificant to lives. The number of goats suffered from retained fetal membranes and subsequent uterine infection were 27 in bromocriptine group, 38 in prosolvin group, 1 retained placenta and 2 uterine infections 5 in dexamethasone group and 08 in control group, with no significances recorded between the groups.
