GPT and fetal growth restriction: Several research studies have investigated how the liver is affected by naturally occurring IUGR in pigs over time.[9, 11] On the other hand, males seem to be more susceptible to IUGR‐induced homeostatic disruptions.[9a] Liver function tests revealed altered serum indicators for IUGR male piglets, such as AST, ALT, ALB, TP, as well as unusual levels of ALP and CHE activity.
