Abstract

The purpose of this study was to compare the reproduction performance of imported dairy cows (G0) and their first offspring (G1) in the first lactation. This study used secondary data collected by BBPTU-HPT Baturraden, Purwokerto, from April to August 2020. The variables observed were age at first partus, service per conception (S/C), days open and calving interval. The data was analyzed using an unpair test (independent sample t-test) to compare the mean between G0 and G1. The results showed that there are no significant differences in reproduction performances in G0 and G1. However, the G1 cows had the higher values in all parameters. The mean values of age at first partus, S/C, days open, and calving interval of G0 and G1 cows were 772.48 and 793.31 days, 2.20 and 2.39 times, 209.94 and 245.91 days, 488.21 and 494 days, respectively. It could be concluded that the reproduction performance of G0 and G1 are relatively similar.
