Lactobacillus amylovorus and Improved Growth Performance

Research synthesisLow evidenceMixed effect size4 studies · 4 beneficial · 0 neutral · 0 harmful

Across 4 studies, all 4 reported beneficial effects on growth performance. Effect sizes were mixed (small, moderate, large). Statistically significant results were found in 3 of 4 studies. The most common study populations were weaning pigs and newborn piglets/mice; doses and forms were not consistently reported.

  • Studied populations: weaning pigs, newborn piglets, intrauterine growth restricted (IUGR) piglets, Asian seabass fingerlings, weaned lambs

Caveats: Evidence base is small (only 4 studies) — conclusions should be considered preliminary. 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). Study populations and designs vary widely (pigs, fish, lambs, mice), making direct comparisons difficult. One study (Asian seabass) showed a 33% body weight increase but had an evidence score of 0 and no study type recorded.
