Blagnac, France -- Lallemand Animal Nutrition was pleased to contribute to the 11th Poultry Research Days (“Journées de la Recherche Avicole et Palmipèdes à Foie Gras”), in Tours, France, as a sponsor and scientific contributor. This biennial poultry congress was the opportunity to showcase our latest research in poultry nutrition and probiotics applications through a poster and oral presentation. This was the occasion to confirm Lallemand Animal Nutrition’s commitment to drive poultry research forward.

1. BACTOCELL survival in hens’ gut

The first study1 presented was conducted by Lallemand Animal Nutrition R&D team in partnership with leading premixer INZO°. The originality of this study was to look beyond probiotic efficiency at their mechanisms of action inside the gut.

The aim of the trial was to follow the fate of live bacteria Pediococcus acidilactici MA 18/5 (BACTOCELL®) along the intestinal tract of laying hens. Increasing doses of the probiotic were administered to laying hens. Numeration of the live bacteria was performed in the various compartments of the digestive tract at different time points.

  • First of all, the study confirmed that BACTOCELL® is able to survive through the birds gastro-intestinal tract but does not colonize the gut. The bacteria was found alive through the hens digestive tract but only during the period of supplementation.
  • There is a dose response effect with BACTOCELL® in the absence of stress factor. The live bacteria was found in proportion of the inclusion rate in the various parts of the digestive tract. However, this dose response tended to saturate above the commercial dose (1.106 UFC/g), but only in the caeca.

2. Broiler meat quality: Cellulitis management

The second study was conducted in partnership with Toulouse Vet School and feed company Huttepain2. It looked at the benefits of probiotic yeast supplementation on the incidence of cellulitis in broiler chickens.

In recent years, cellulitis has emerged as a major skin disease in poultry. Condemnation of broiler carcass due to cellulitis represents a growing financial burden for the industry (e.g. in the USA, cellulitis is the second cause of partial condemnation of chicken carcasses).
The study presented indicated that the addition of live yeast (Saccharomyces cerevisiae boulardii I-1079) to the feed of broiler chickens is beneficial to reduce cellulitis incidence, especially in at-risk conditions.
