Abstract
In the study of the reproductive performance in indigenous cattle in 1988 and 1989 at the Ghibe valley in Ethiopia, calving interval was 507.5 ± 9.4 days and days open were 232.4 ± 13.9. Abortion rates were 16.8 and 16.3% of 179 and 43 cattle in 1988 and 1989, respectively, with significant (P < 0.01) seasonal differences. The control of the seasonal flare-up of trypanosomiasis and other health-management interventions were suggested as the possible remedy to overcome reproductive wastage in the future.
