Growth Performance
All the pigs were allowed a 28-d nursery adaptation where pigs were provided ad libitum access to feed in a pen followed by a 10-d controlled feeding program in metabolism crates. During the first 28-d nursery adaptation period, 1 pig from the first group fed original CA and 1 pig from the second group fed SO PF died. For the growth performance portion of the experiment, there were 3 observations per treatment consisting of 3 pens with 8 to 9 total pigs. For all other data, there were 8 or 9 observations per treatment.
During the first 28 d, no lipid source or lipid source × peroxidation interactions were observed for ADFI and ADG (Table 3). In contrast, peroxidation level affected both ADFI (P = 0.09) and ADG (P = 0.04). Compared with pigs fed OL, pigs fed RO lipids tended to have reduced ADFI (P = 0.09) and reduced ADG (P = 0.03). No differences in ADG or ADFI were found between pigs fed SO lipids and OL or between pigs fed SO and RO lipids. There was no lipid source × peroxidation level interaction noted for G:F, but lipid source affected G:F (P = 0.02), where pigs fed CA supplemented diets had a lower G:F compared with pigs fed the other 3 lipid supplemented diets (P < 0.05).
