Blagnac, France ‒ Lallemand Animal Nutrition presented the latest research in poultry nutrition and probiotics applications through a poster and oral presentation at the 11th Poultry Research Days.
Mode of action
The first study 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.
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 were 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.
The second study was conducted in partnership with Toulouse Vet School and feed company Huttepain. 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. 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.
