An experiment (Exp.) was conducted to determine the influence of refined soybean oil (SBO), recycled soybean oil (RSO), and acidulated soybean oil soapstocks (ASO) and the effects of inclusion of vitamin E in diets containing 3.5% of these soy oils on yolk phospholipid fractions and positional fatty acid profiles. In this Exp. there were 6 treatments arranged factorially with 3 oil sources (SBO, RSO, and ASO), and two levels of vitamin E (0 vs. 250 mg/kg). Results showed the soy oil source and vitamin E supplementation affected the content and positional FA profile of the PL fractions.
