Effective pathogen control

Control Gram-negative bacteria with a combination of short-chain glycerides and lactic acid.

Lactic acid

The anti-bacterial action of lactic acid against Gram-negative bacteria is largely assigned to its ability to penetrate the cytoplasmic membrane in its undissociated form. Inside the bacteria lactic acid dissociates, decreasing the intracellular pH and disrupting the transmembrane proton motive force. Lactic acid is also able to reduce the barrier function of the outer membrane of Gram-negative bacteria enabling components such as glycerides to penetrate more easily.

Therefore, the combination of lactic acid and glycerides is an ideal concept inhibiting Gram-negative bacteria in livestock.

“FRA LAC34 can increase ADWG with more than 4% in poultry production, while reducing FCR.”

Propionic- and butyric acid glycerides

Glycerides of short-chain fatty acids, as from propionic- and butyric acid, are mainly active against Gram-negative bacteria such as Escherichia coli and Salmonella spp. Gram-negative bacteria are mainly affected by interference and destruction of genetic material. This will affect normal cell division and bacterial growth. Combining this product with medium-chain glycerides enables farmers to reduce heavy use of preventive antibiotics.

Reduce FCR

Research has shown that FRA LAC34 increases average daily weight gain (ADWG) with 5% on average. Meanwhile, feed conversion ratio (FCR) reduces when using FRA LAC34. Therefore, this feed additive has a very strong return on investment (ROI). Demonstrating that FRA LAC34 is a proper addition to any production cycle.
