we observed that Yorkshire piglets had a higher concentration of HDL-C than Meishan piglets, together with the results of LDL-C that no statistical significance existed
between the two breeds, indicating that more cholesterol in the serum of Yorkshire piglets could be transported into the liver and be oxidized.
But considering the higher serum TC concentration of Yorkshire piglets, we consider this may indicate that Yorkshire piglets absorb more cholesterol from sow's milk or have a higher
endogenous synthesis rate.
