Abstract:
The aim of this study was to calculate the calving interval and reproductive efficiency by the effect of parity in a dual-purpose herd in the Mexican tropics. The prospective observational study of the cows´ reproductive records from the year 2013 to 2021 was analyzed. The records with reproductive pathology and non 50% Bos indicus and 50% Bos taurus were taken out. In total, 67 intervals between calving of 24 cows were gotten from a farm in the Mexican tropics. The genotypes were 50% Bos indicus (Gyr) genes and the remaining 50% genes came from Holstein, Fleckvieh, and Brown Swiss. A linear model as a simple design of fixed effect was used. The mean calving interval was 485 ± 121 days. Parity factor had an effect on the calving interval. The correlation between these two variables was - 0.46 (p<0.01). In conclusion, parity affected the calving interval in this dual-purpose cattle herd; parity is proportional inversely to the calving interval. 60% reproductive efficiency was obtained.
