Levucell improves sow’s feed intake

Blagnac (France) – Results of a meta-analysis show that probiotic yeast Saccharomyces cerevisiae boulardii CNCM I-1079 (Levucell), helps increase sow feed intake during lactation.

Probiotic effect

The study was presented by Lallemand Animal Nutrition at the American Dairy Science Association (ADSA) and American Society of Animal Science (ASAS) Joint Annual Meeting in Orlando, Florida.

Optimal feed intake in early lactation is key to ensuring sufficient milk production and limiting sow body weight loss, which impacts both piglet and sow performance. These results confirm the monogastric-specific probiotic represents a valuable tool for lactating sows management.


The meta-analysis encompassed 10 recent commercial trials performed with S. cerevisiae boulardii CNCM I-1079 throughout Europe and North America and included 1,111 sows. This robust statistical method showed an overall significant effect (P< 0.05) of the probiotic on sow feed intake in lactation ranging from 0.180 to 0.260 kg of extra feed /day/sow (depending on the statistical model used).

Eric Chevaux, Applied R&D Manager for Lallemand Animal Nutrition, says the probiotic action of S. cerevisiae boulardii CNCM I-1079 helps improve sow feed intake by balancing the microbiota of the digestive system.

“When it comes to feed intake measurement, inter-individual variability remains high, even when parameters such as parity, feed or environment are fixed,” Chevaux says. “This meta-analysis was conducted in order to bring a quantitative evaluation on the effect of the live yeast on sow feed intake in lactation.”
