¹A total of 700 maternal line barrows (200 × 400 DNA, Columbus, NE; initially 6.5 kg body weight) with five pigs per pen and 28 replications per treatment were used in 21-d growth trial.

²Two batches of LT Prime Menhaden Fishmeal were manufactured with 0.87% and 24.35% soluble fractions (Daybrook Fisheries Inc., New Orleans, LA). Treatment diets with 0.87% and 24.35% solubles were then blended to create the intermediate diets with 8.70% and 16.52% solubles that were all added at 6% to the diet.
