¹Difference in dietary treatments were created by either no heat treatment to spray-dried plasma (20 °C), heating plasma at 45 °C for 3 d (45 °C), or heating at 100 °C for 3 d (100 °C). There were 10 individually penned gilts per treatment with an initial BW of 12.5 ± 1.5 kg.

²In addition to analyzing as individual treatments, a contrast was analyzed and the resulting P-values for a linear relation between response variables and carbonyl values in the diet are reported.

^a,bDifference in superscripts within row indicate significant differences between treatments.
