Sow reproductive and progeny growth performance when fed yeast postbiotic: systematic review and meta-analysis.

Previous research suggested that feeding sows with a product containing an inactivated strain specific yeast postbiotic (; Citristim, ADM Animal Nutrition, Quincy, IL) has the potential to support fecundity, and progeny performance at birth, weaning, and after weaning. To summarize these effects, a systematic review followed by a meta-analysis was carried out to determine the effects of feeding sows with PG during gestation and lactation on reproductive the performance of sows and the growth of progeny after weaning. All experiments included were randomized trials reporting side-by-side comparisons of an appropriate control () and the CON with the inclusion of PG.
