The effect of camelina meal on the pig liver gene expression level of Cyp8B1, TST, Aldh2, and Gstm5. Transcripts were determined by real-time PCR with porcine specific primers. Pig diets were supplemented with either the Control (0%), Low (3.7%) or High (7.4%) levels of camelina meal for 24d. Error bars represent the standard error of the mean. * indicates P > 0.05 relative to the Control using Student’s t-test.
