Bottom line. Independent evidence supports the core idea that yeast/alternative proteins can replace fish meal and soy protein concentrate in weaner diets without loss of performance, and can improve protein digestibility.

Used as a protein ingredient, not a micro-dosed additive.
Independent evidence supports the core idea that yeast/alternative proteins can replace fish meal and soy protein concentrate in weaner diets without loss of performance, and can improve protein digestibility.
Bioprocessed alternative proteins can also improve gut-health and immune markers, supporting Cellpro's gut/immune positioning at the class level.
However, the independent data show parity rather than the superiority the brand claims; the '+500 g versus other proteins' result is a company trial.
Replacing ALL expensive animal protein can reduce growth, so the benefit depends on how much and what is replaced.
No independent study of Cellpro itself, nor of the zinc-reduction claim, was located.
Where studies disagree: Independent yeast-protein studies show parity with conventional proteins, not the superiority ('better results', '+500 g') stated by the manufacturer; full replacement of animal protein can even reduce growth.
Gaps: No independent trial of Cellpro itself. Little weaned-pig literature on yeast+vegetable-protein co-products specifically. The zinc-reduction claim is unverified by independent data.
Manufacturer’s stated mechanism (their words): A yeast-plus-vegetable-protein co-product providing highly digestible protein plus yeast cell-wall components (beta-glucans/mannans) proposed to support gut barrier and immune development, allowing replacement of fish meal and soy protein concentrate.
