Interpretive Summary:

Technical Abstract: Oil source has been shown to affect broiler performance and oxidative status. Lipid peroxidation may also affect animal performance and oxidative status through the generation and degradation of peroxidation compounds which differ according to oil source and temperature and length of heating. The objective of the study was to evaluate the effect of oil source and peroxidation status on broiler performance and measures of oxidative stress. Broilers (initial BW 85.1 ± 7.8 g) were allotted to 40 battery cages in a completely randomized 4 × 2 factorial arrangement of treatments. Treatments consisted of oil source (palm oil, soybean oil, flaxseed oil, and fish oil) in combination with lipid quality (fresh or peroxidized oil). Peroxidation was achieved by thermally processing each oil at 90 C for 72 h with a constant air flow of 3 L/min. Oils were analyzed for peroxide value, anisidine value, hexanal, 2,4-decadienal, and total polymers as measures of oil peroxidation. Each treatment was replicated 5 times with 5 birds/cage (200 birds), with birds fed their respective diets for 20 d to measure performance criteria. On d 21, plasma was harvested from 2 birds from each cage for analysis of oxidative status, which included thiobarbituric acid reactive substances (TBARS), protein carbonyls (PC), 8-hydroxy-2'-deoxyguanosine (8-OH-2dG), and glutathione peroxidase activity (GPx). An interaction between oil source and peroxidation status was noted for ADFI, ADG, and F:G (P = 0.01), where birds fed the peroxidized oil reduced ADFI, ADG, and F:G in all oil sources except for birds fed the fish oil. There were no interactions noted between oil source and peroxidation status for TBARS, PC, 8-OH-2dG, or GPx (P > 0.10). Oil source increased plasma TBARS and 8-OH-2dG (P = 0.01), and tended to increase plasma PC (P = 0.09), but did not affect plasma GPx (P > 0.44). Although lipid peroxidation had no effect on plasma TBARS or PC (P > 0.15), plasma 8-OH-2dG and GPx were affected by lipid peroxidation (P < 0.01). In conclusion, oil source and peroxidation status differentially affected growth performance, oil source increased plasma TBARS, PC, and 8-OH-2dG, and lipid peroxidation increased plasma 8-OH-2dG and decreased plasma GPx.
