Efficacy of estrus synchronization and fertility after synchronization of 60 multiparous Mashona goat does using intravaginal progesterone (P4) sponges (Group 1), norgestomet ear implants (Group 2), cloprostenol (Group 3), or a combination of P4 sponges and cloprostenol (Group 4) was compared with untreated does (Group 5). At the end of treatments, all does were mated to intact fertile bucks for 21 d. The number of does bred within 11 to 96 h was significantly higher (P < 0.05) in the treated groups than the untreated control, with rates of 80, 80, 64, 67 and 30% for Groups 1 to 5, respectively. There were no differences (P > 0.05) among treated does. Kidding rates ranged from 64 to 83% but were not different (P > 0.05) between groups. Prolificacy and overall fecundity were similar (P > 0.05) among the groups. The results indicate that all 4 treatment methods were effective in synchronizing estrus and that none of the methods affected overall fertility of the does.
