Calculator to optimise pig and broiler feed
Beta-mannans can cause an FIIR in broiler chickens and pigs.
An online calculator has been launched to support the assessment of beta-mannan levels in pig and broiler diets.
The free tool, produced by Elanco, will support more informed decisions for feed formulations, which could lead to improved animal productivity and health.
Beta-mannans are found in many raw materials, such as soya, sunflower and cereals. Elanco says they are often overlooked regarding their impact on animal performance.
The organisations says that beta-mannans mimic the structure of pathogenic organs, causing them to trigger an unnecessary response in the animal’s immune system. This is known as a Feed-Induced Immune Response (FIIR).
The FIIR diverts nutrients and energy away from productive functions. This causes inflammation within the gut, reduces nutrient absorption, lowers feed conversion and increases the risk of secondary infections.
Dr Tom Dutton, a technical consultant for Elanco, says that even a minimal amount of beta-mannans (0.20 per cent) is enough to trigger an FIIR. He says that improving visibility of beta-mannan levels will allow for a more targeted approach to feed formulation.
This could mean including the energy-sparing enzyme beta-mannanase in diets to break down the beta-mannans and reduce their impact.
He said: "The new calculator can be used to assess beta-mannan risk at any stage of the diet. By using ingredient percentages entered by the user, it estimates beta-mannan levels in the ration and identifies if the inclusion of Hemicell XT would be beneficial,”
“Identifying and taking action to counter beta-mannans in diets is an important step in improving feed efficiency, supporting gut function, and helping animals perform to their full potential.”
The calculator is available for free on the Elanco website.
