The difference between PEP50 and PEP2+
is that PEP50 consists of hydrolyzed porcine intestinal
mucosa and dehulled soybean meal (SBM; 47.5% CP),
whereas PEP2+ is produced by mixing hydrolyzed porcine
intestinal mucosa with DFB and enzymatically processed,
low-antigen SBM (HP 300; Hamlet Protein A/S, Horsens,
Denmark).
