USG image of cows uterine involution with retained fetal placenta which is treated using sulfadiazine dan trimethoprim in bolus

Abstract

The effect of retained fetal placenta on uterine involution was observed in 9 Holteins cows under dairy farm conditions which were divided into 3 groups (3 cows/group). Group RP+B is cows with retained fetal placenta which was treated using bolus antibiotics, group RP-B is cows with retained fetal placenta which was not treated using antibiotics and group N+B is normal parturition cows which obtained same treatment with group RP+B. The current study was conducted to observe the USG image of uterus involution to record cervic and cornua uterus diameters by ultrasonography in cows in those three groups. In addition, the total number of leukocytes was also observed in 9 Holteins cows. The result of this research showed that bolus was not significant to the decline of cervic uterus diameter, cornua uterus diameter and total number of leukocytes (p>0.05). In contrast, period showed significant influence (p<0.05). USG image of cervic and cornua uterus and its diameter showed that in Group N+B needs five weeks until the cows were getting estrus with the diameter of cervic 5.43±0.49 cm and cornua uterus reached diameters 5.19±0.61 cm. Both group RP+B and group RP-B need 8 weeks with the diameter of cervic 5.12±0.13 cm and cornua 4.23±0.34 cm, cervic 5.83±1.04 cm and cornua 5.50±0.62 cm respectively. The total number of leukocytes of Group N+B which become estrus in five weeks is 6248.67±220.15 whereas group RP+B and group RP-B need 8 weeks with the total number of leukocytes is 6216.67±76.38, 6966.67±663.95 respectively. In conclusion, bolus is not significant to the decline of uterus diameter and total number of leukocytes in cows with retained fetal placenta until the 5th week of observation. However, they have smaller uterus and less number of leukocytes than cows with retained fetal placenta which was not treated using bolus antibiotics.
