Relative expression of PepT1 and AA transporters in the rumen, omasum and duodenum

The mRNA expression of PepT1, ATB^0,+, ASCT2, and y⁺LAT1 in the duodenum was higher than that in the rumen and omasum (2^−ΔΔC_T value). For the calculation of PepT1 expression, the rumen was chosen as calibrator (a), and for AA transporters, the omasum was chosen as calibrator (b, c, d). Values with different letters (A and B) are considered to be significantly different (P<0.05). Data are expressed as mean±SE (n=6)
