The third stage of birth is placenta expulsion which can occur about 30 minutes after the release of the fetus but is more likely to occur between 180 to 300 minutes later. This research is expected to provide an understanding about the different time on placenta expulsion, the number of cotyledon and placenta weight that faced up by veterinarian. Cows with a body condition score between 2.5 to 3.5 and ready to give birth from various breeds were used in this study. The results showed that young cows (<5 years old; 366,50 ± 30,97 minutes) significantly had a longer placenta expulsion time than old cows (>5 years old; 251,29 ± 7,55 minutes; p<0,05). While the amount of cotyledon and placenta weight did not differ between the two age groups. Based on breeds, the young Ongole cows showed significant different on placenta expulsion time compared with old ones (397,25 ± 61,60 vs 250,80 ± 14,79 minutes; p<0,05) but had no difference with the young and old crossbreed cows. Young cows need more time for placenta expulsion than the old ones and the young Ongole cows take the longest time compared to other age and breed groups.
