where Y k represents the dependent variable of interest, µ is the overall mean, S k is the fixed effect of FA stock or supplement, and e k is the residual error. The PA, SA, and SA/PA blend supplements were compared using a protected least significant difference (LSD) separation. Comparison of the 11 FA stocks was conducted using a Tukey's test. A significant effect of stock was declared at P ≤ 0.05. Studentized residuals were used to check for outliers (outside ± 3.0), but no data points met criteria.
Differences in MT and enthalpy between the first and second thermal cycles was analyzed using the REML method in the fit model procedure of JMP Pro 13.1 (SAS Institute Inc.) using a protected LSD mean separation using the following model:
where Y jkl represents the dependent variable of interest, µ is the overall mean, R j is the random effect of replicate (j = 1 to 3), S k is the fixed effect of FA stock or supplement, T l is the fixed effect of thermal cycle (l = 1 or 2), and e jkl is the residual error.
