Lallemand: Multi-strains yeast product helps control coccidiosis in broilers
Lallemand Animal Nutrition has recently affirmed its commitment to poultry nutrition research at the 15th European Poultry Conference in Dubrovnik, Croatia.
The company, which sponsored the event, presented six new studies on the benefit of probiotics, yeast derivatives and antioxidants in poultry nutrition, in posters and one oral presentation. Two of these presentations showed, for the first time, the potential of a multi-strains yeast fractions product which would 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 to serve as components of management programmes. In regards to this recommendation, two studies were conducted in partnership with Aristotle University of Thessaloniki (Greece) to evaluate the potential of a multi-strains yeast fractions product in broilers, either functioning 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 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. The positive developments reported were improved digestive microbiota balance, less severe intestinal lesions; higher gut villi and the enhanced performance of animals.
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.
The feed conversion rate also improved. Furthermore, the trial showed that multi-strains yeast fractions can help mitigate coccidiosis' negative effects in a dose-sensitive manner.
