Trouw Nutrition has launched a novel feed additive that combines three complementary modes of action to help reduce the shedding and transmission of pathogens in pig herds.
Fysal Solute will play a key role in the company’s salmonella reduction programme, helping to further reduce the use of antibiotics in pig production. The product can be added to compound feeds or premixes.
“It has been estimated that by 2050 anti-microbial resistance (AMR) will be the leading cause of death in humans, with Salmonella and E coli being a major part of the issue,” comments Trouw Nutrition’s monogastric feed additives manager Dr Sophie Prentice. “Whether we like it or not, the perception of society is that farming is becoming increasingly unsustainable with the use of antibiotics a growing part of that negative perception. AMR is a global trend that will influence the way we produce our food in the future, and we as an industry need to be proactive.”
Dr Prentice adds that the EU-wide ban on the use of zinc oxide at medicinal levels in piglet feeds, which comes into effect in 2022, adds further pressure to identify new methods to maintain animal productivity and welfare by controlling E coli and Salmonella.
Fysal Solute has been developed to increase the binding of Salmonella and E coli while also supporting immune function and the growth of beneficial bacteria. Hydrolysed copra meal is included as a source of mannobiose, an indigestible disaccharide of mannose, while fermented rye provides beta glucans, glycoproteins, bioactive peptides, prebiotics and phenolic compounds.
“Fysal Solute provides a high level of efficacy by acting through three main mechanisms, Dr Prentice continues. “By binding Salmonella and E coli, it leads to fewer bacteria attaching to the intestinal cell wall, while it encourages the competitive exclusion of less desirable bacteria by promoting the growth of beneficial bacteria. Finally, it supports a functional immune system under challenging conditions.
“Together these mean Fysal Solute can dramatically reduce shedding and transmission of pathogens within the herd and, therefore, the risk of infection to healthy animals, as the primary infection route is faecal-oral and contamination risks increase with pathogen load,” she concludes.
