Across 4 animal studies, all 4 reported beneficial large effects of Lactobacillus plantarum on growth performance, with 3 of 4 reaching statistical significance. The evidence is derived exclusively from broiler chickens, weaning pigs, and fish, with no human trials available. Doses and forms were not consistently reported.
- Studied populations: Animal models (broiler chickens, weaning pigs, young piglets, Labeo rohita fish)
Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Evidence base is small (only 4 studies) — conclusions should be considered preliminary. All studies used different strains of L. plantarum (B1, CJLP243, VSG3) rather than the specific strain UALp-05M. Most importantly, all studies were conducted in animals, and no human trials have been identified; applicability to human growth performance is unclear.
