Abstract

Bioorgan transgenic cloned mini pig has a problem of growth retardation in uterus during end of pregnancy so that survival rate is very low in newborn piglet. In order to support their life after birth, cesarean section of fetus with sufficient growth in uterus was tested in this study. First of all, fetus growth measured using a ultrasound scanner during pregnancy in transgenic mini pig, comparing normal pig. After 113 days for delivering, fetus was removed out of uterus. Fetus growth for normal pig was 1.8 cm at 4weeks and 14.4 cm at end of pregnancy (15 weeks). At 113 days, fetus growth was $15.9{\pm}4$ cm in ultrasound scanner and real growth measurement from fetus removal out of uterus was $16.0{\pm}2$ cm. It is very a similar result between measurement of ultrasound scanner and real measurement. Therefore, using ultrasound scanner for measuring fetus growth will be useful to predict fetus growth in uterus.
