^aCON = 1% diet soybean oil; LOW = 0.5% diet soybean oil, 0.5% diet CLA; HIGH = 1% diet CLA.

^bTrt = main effect of treatment for the 56-d trial.

^cContrast = quadratic contrast of dietary treatments to d 42, prior to the LPS challenge.

^a–cSuperscripts denote differences between dietary treatments (P < 0.05).
