Lallemand explores methods for assessing gut health at 74th EAAP Congress in Lyon, France

 

 

Lallemand Animal Nutrition's R&D team is participating in this week's Joint International Congress on Animal Science co-organised by the European Federation of Animal Science (EAAP), the World Association for Animal production (WAAP) and Interbull in Lyon, France.

 

Lallemand's poultry and ruminant experts are to present practical on-farm assessment tools aimed at optimising animal health and well-being at the congress dedicated to the topics of climate change, biodiversity and global sustainability of animal production.

 

Poultry applications manager Audrey Sacy is to present a poster introducing a novel on-farm assessment technique for evaluating poultry intestinal health. This method employs a fecal scoring system for simple and effective measurement. The study's findings reveal a strong correlation between the fecal score and fecal dry matter (DM) content. 

 

By utilising this method, the team assessed the benefits of supplementing poultry diets with the live yeast Saccharomyces boulardii CNCM I-1079. The probiotic supplement demonstrated improvements in fecal score and DM content. This offers potential direct consequences on litter quality and the reduction of pododermatitis occurrence in poultry farms.

 

Ruminant research scientist Clothilde Villot shared a poster about the use of wireless reticulo-rumen pH sensors in dairy cows for early detection of rumen disorders. The objective of this work was to develop an additional panel of indicators towards defining rumen health beyond traditional average rumen pH measurements. This work considered the real time kinetics of reticulo-rumen pH and the potential impact of external factors such as environment, feeding behavior and feed quality.

 

Explaining the significance of the team's work, Villot said: "With the abundance of data generated by on-farm sensors, it is a challenge but also an opportunity to develop advanced algorithms and models to analyse and interpret the information effectively.

 

"Our aim was to generate indicators carrying additional information on reticulo-rumen pH variation to improve rumen disorder detection. Combining pH parameters with other automatically recorded and calculated feeding behavior and performance indicators is the upcoming challenge that could help us understand better the rumen function — empowering farmers and nutritionists to make informed decisions."

 

Ruminant marketing manager Marie-Valentine Glica said: "Lallemand has been at the forefront of studying rumen health and microbiota dynamics for more than two decades. We continue to invest in research to develop on-farm indicators and tools that empower nutritionists to provide practical decision-making support to farmers. These tools enable the formulation of tailored diets and the implementation of effective farm management systems, ultimately leading to enhanced well-being of ruminants and more sustainable food production from dairy cows, beef cattle, as well as sheep and goats.

 

"The recent development of smart-farming devices, such as rumen and reticular pH sensors, has provided us with a wealth of data. Being able to analyse and interpret this data poses new challenges, but it also unlocks opportunities for improved animal health and productivity."
