Trial 2: Weaned piglets; day 1-35

Initial weight (kg) 6.8 6.9 .59
Final weight (kg) 18.5a 19.3b .03
ADG (g/d) 343a 363b .03

• Concentrates (35% of DM) are identical in both treatments
• Concentrates includes “insurances” (i.e.. organic acid)
Difference trial 1 versus trial 2:
• First 5 days after weaning both treatments got very luxury feed
• First 5 days both groups (except 10% ferment mix was fermented versus non-fermented) was identical.
