Effect fish oil inclusion in low protein quality diets on serum Hp concentrations of pigs after weaning. Each mean represents observations on 12 pigs. Dietary treatments: [1] positive control (High; contained multiple sources of proteins, including animal proteins and 5% corn oil), [2] negative control (Low0; contained soybean meal as the main protein source and 5% corn oil), or 1 of 3 Low diets supplemented with increasing levels of fish oil to replace corn oil: [3] 1.25% fish oil (Low1.25), [4] 2.5% fish oil (Low2.5), [5] 5% fish oil (Low5) fed in 2 phases (7 and 14 d, respectively). All pigs received common phase III diets thereafter for 3 wk. ^a,bValues with different letters within the same panel differ (P < 0.05).
