Multi-strains yeast fractions product helps reduce impact of coccidiosis on broilers

Multi-strains yeast fractions product helps reduce impact of coccidiosis on broilers

Lallemand Animal Nutrition confirms its commitment to poultry nutrition research at the XVth European Poultry Conference in Dubrovnik, Croatia. The company, sponsor of the event, presented six new studies on the benefit of probiotics, yeast derivatives and antioxidants in poultry nutrition, as posters and one oral presentation. Two of these showed for the first time the potential of a multi-strains yeast fractions product to help reduce the impact of coccidiosis in broiler chickens.

As resistance to anticoccidials is a growing concern for broiler producers, alternative strategies to help control coccidiosis are being evaluated. Nutritional solutions have been suggested as part of overall management programs. Two studies conducted in partnership with Aristotle University of Thessaloniki (Greece) have been performed to evaluate the potential of a multi-strains yeast fractions product in broilers, either alone or in combination with anticoccidials.


The study selected for oral presentation was done with 192 one day old chicks and aimed at evaluating the effect of the yeast product in combination with the anticoccidial salinomycin, in feed, on gut health and performance of broiler chickens. The birds were orally challenged with a mix of the three most common coccidian oocysts found in broilers. The study showed that the combination exerted a substantial improvement in intestinal health in coccidiosis challenged birds:

  • improved digestive microbiota balance
  • less severe intestinal lesions
  • higher gut villi

In the second trial, different doses of the multi-strains yeast fractions were assessed in the presence of different pathogen challenges (Eimeria acervulina, E. maxima, and E. tenella). Lesion scores were improved and coccidiosis related mortality was numerically reduced when the yeast product was supplemented in the feed. FCR was also improved. The trial showed that the multi-strains yeast fractions can help birds to mitigate coccidiosis negative effect in a dose-sensitive manner.
