Effects of alfaprostol and luprostiol on the embryo production within MOET technique in Black Bengal goats

The effects of Alfaprostol and Luprostiol on embryo production within multiple ovulation and embryo transfer (MOET) technique were studied on 16 Black Bengal goats during the period from January 2002 to June 2003. These 16 goats were randomly divided into two equal groups (A & B), each consisting of 8 goats. Each of the 16 goats was flushed in different times within MOET technique to determine the effects of alfaprostol and luprostiol on embryo production. Each group consisting of 8 donors was synchronized with alfaprostol (Gabbrostim®, VETEM, Italy) or luprostiol (Prosolvin®, Intervet International, Netherlands) @ 2 mg and 7.5 mg, equivalent to 1 ml / donor respectively. The donor goats were hand mated following the onset of oestrus, 1-2 times at 6 h interval depending on the duration of oestrus. The embryos were collected at Day 7 of mating using surgical recovery method. The mean number of ovulation in alfaprostol and luprostiol group was 8.50 ± 0.90 and 8.1 ± 0.76, respectively, where in both cases 900 iu PMSG was used for induction. There was no significant (p > 0.05) difference between this two groups on superovulation rate. The mean numbers of recovered, fertilized and transferable embryos were 5.4 ± 0.80 and 5.1 ± 0.61; 3.9 ± 0.52 and 2.6 ± 0.37 and 3.6 ± 1.6 and 2.4 ± 1.0, respectively, in alfaprostol and luprostiol treatment group. Like superovulation, there was no difference between the two treatment groups on recovered, fertilized and transferable embryos. The percentage of recovered, fertilized and transferable embryos were 63 ± 7.7 and 63 ± 3.74, 72 ± 4.55 and 51 ± 7.0 and 93.6 ± 1.6 and 90.48 ± 1.0 in alfaprostol and luprostiol treated groups, respectively. The significant difference was only existed in the percentages of fertilized embryos between the two treatment groups, where alfaprostol treated group had the significantly (p < 0.01) higher percentage of fertilized embryos.Key words: Alfaprostol; luprostiol; effect; embryo transfer; ovulation; Black Bengal goatsdoi: 10.3329/bjvm.v2i2.2558Bangl.
