The effects of Sheng Hua Tang (SHT) on uterine involution and ovarian activity were investigated in postpartum dairy cows. SHT (70 g) was given to dairy cows (n = 10) to evaluate its effects for five days from the first postpartum day. Postpartum cows fed with a basal diet without SHT were used as the control group (n = 10). Ultrasounds and blood tests were recorded for four weeks from postpartum day seven with a 3-d interval. The results showed that the areas and diameters of endometria were significantly (p<0.01) reduced in the group that received SHT compared to the control group on the seventh postpartum day. The group that received SHT had an intrauterine fluid volume mean of $1.2{\pm}0.6cm^3$, which was significantly lower than that of the control group, $2.3{\pm}0.8cm^3$ (p<0.01) on the 13th postpartum day. In addition, the uterine tension score was a mean of $1.0{\pm}0.0$ in the group that received SHT, which was also significantly lower than that of the control group, $1.5{\pm}0.5$ (p<0.01) on the 19th postpartum day. Taken together, the Chinese herbal medicine remedy, SHT, promoted uterine involution and ovarian activity in postpartum dairy cows.
