Is management of microbial ecosystems the key to better broiler performance?

So says Lallemand Animal Nutrition as it publishes abstracts about some of its latest scientific findings related to yeast and broiler production. Presentations on the e-posters will be delivered at the World Poultry Congress (WPC) in August 2022 in Paris.

A study was conducted by two research teams at the University of Thessaloniki and the University of Ioannina to evaluate the effects of the combination of Lallemand’s multi-strain yeast fraction product (YANG) and the coccidiostat, salinomycin, on the performance and health of broiler chickens orally challenged with coccidian oocysts.

When compared to controls, the combined supplementation was the only treatment that showed significantly improved bodyweight of the broilers at days 21 and 26 of age along with a lower feed conversion rate (FCR), said the authors.

The combined treatment, as compared to the coccidiostat alone, showed a lower lesion score at day 21 and significantly lower coccidia contamination of the different gut compartments: duodenum, ileum, and ceca, they continued.

“We conducted two previous trials in a coccidiosis environment with YANG, but this is the only trial using YANG in combination with a coccidiostat,”​ a spokesperson for Lallemand Animal Nutrition said

The results will be used as a tool or model to confirm the immunomodulatory effects of that product, added the representative.

Probiotic paper

Lallemand also flagged a metanalysis of trials of its live yeast probiotic.

To date, it said, the use of the live yeast, Saccharomyces cerevisiae boulardii​ CNCM I-1079 (LEVUCELL SB), to improve the performance of broiler chickens has been documented in controlled research trials, as well as in field evaluations.
