Our findings in the project indicates that in a wean to finish system: Antibiotics may not be necessary for performance of pigs in a wean to finish system. Antibiotics modifies the micro-flora of the gastrointestinal tract by reducing total aerobes and an-aerobes. Sugar beet pulp can be used as substitute for antibiotics after the first two phases (5.7 to 20 kg BW). Inulin from chicory pulp can be used as an alternative to antibiotics from phases 1 to 5. Sugar beet pulp reduces dressing percentage but reduces back fat thickness and maintains lean yield.
