Effects of alfaprostol and luprostiol on the oestrus synchronization responses in Black Bengal goats

Sixteen adult Black Bengal goats were synchronized in 2 groups with Alfaprostol (Gabbrostim® VETEM, Italy) or Luprostiol (Prosolvin®, Intervet, Netherlands) @ 2 mg and 7.5 mg, equivalent to 1 ml / donor respectively during the period from January 2002 to June 2003. The IM injections were given at 11 days interval. The percent of animals responded following 1st injection of Alfaprostol and Luprostiol was 75% and 87.5%, respectively. However, all animals responded following of 2nd injection of Alfaprostol, while that of Luprostiol were 87.5%. The mean time of onset of oestrus and duration of oestrus in Alfaprostol group were 36.2 ± 7.91 h and 57.37 ± 6.56 h and 20 ± 4.4 h and 28.5 ± 0.63 h following 1st and 2nd injections, respectively. The similar parameters were 37.5 ± 8.2 h and 49.5 ± 0.46 h and 21 ± 4.6 h and 27.3 ± 0.77 h in Luprostiol group. In both groups there was no significant difference (p > 0.05) between the treatment groups on either the time of onset of oestrus or the duration of oestrus.Key words: Alfaprostol; luprostiol; oestrus; sunchronization; Black Bengal goatsdoi: 10.3329/bjvm.v2i2.2557Bangl.
