Is a 0.4 log reduction clinically relevant in the first 14 days, when there was no difference in the following up to 34 days? With 3 Kg/ton, this seems like a pretty expensive supplement that results in no reduction of Salmonella at the time close to slaughter.

Honestly, I also doubt if 0.4 log units really make a difference. On top this number is an average of 5 studies, which means that some study results might have been even lower or negative. From various scientific publications a drop of minimal 2-3 logs in the cecum are required in order to see really reduction in practise. Also, the "infection level" is too low to obtain representative results. Since the coated butyrate ingredient most probably is the only one reaching the cecum and potentially active there, one can question if it would not be more efficient and more economic to use that component solely at the correct dosage. The low or no effect (second phase) of the product surely does not reflect much synergism.
