RFC'S HELP CONTROL PATHOGENS
With multiple points of entry to poultry facilities; contact with wild birds, rodents and other animals; as well as biosecurity breaches, it can be difficult to contain Salmonella. As a result, infection and pathogen spread can occur at any point in a poultry production system. The implications for animal health and productivity, along with food safety concerns, means poultry producers must focus on ways to keep Salmonella out of their facilities.
Failure to do so can have serious consequences. In the EU for example, more than 100 000 human cases of salmonellosis are reported each year. The European Food Safety Authority estimated that the overall economic burden of human salmonellosis could be as high as EUR 3 billion a year.
Solutions from nutrition
Nutritional solutions like the Refined Functional Carbohydrates (RFC) found in CELMANAX can help provide poultry producers with ways to prevent the spread of Salmonella and other pathogens while delivering nutritional benefits to the flock.
RFCS are the components harvested from yeast cells (S. cerevisiae) using specific enzymes during a proprietary manufacturing process. This enzymatic hydrolysis yields MOS (Mannan Oligosaccharides); Beta 1,3-1,6 glucans; and D-mannose.
These compounds are naturally present in all yeast cells, but are not readily bioavailable. The method of processing used to refine the yeast cells influences the size and structure of these liberated components, which in turn affects bioavailability and functionality.
In the case of RFCS, this enzymatic hydrolysis process significantly increases bioavailability that benefits animal health and productivity. Research shows that each RFC has a specific mode of action and outcome when fed to poultry and livestock.
In poultry, RFCS interfere with Salmonella’s adherence to the intestinal tract, as well as agglutinate the bacteria to render it harmless once it passes through the intestinal tract.
Furthermore, because of the multi-functional nature of RFCS (reducing the effects of harmful pathogens, as well as mycotoxins in feed) less energy is needed for fighting disease challenges and supporting the immune system, making more energy available for growth, synergistically helping poultry performance.
Scientific studies verify the positive benefits of RFCS to help control Salmonella in breeding hens.
For example, a study conducted in the US at North Carolina State University found that prevalence of cecal Salmonella in breeder hens fed the control diet (which did not contain any RFCS), was 71.4 percent. Meanwhile, prevalence of Salmonella in breeder hens fed the RFC diet was 0 percent, as shown in the chart above.
Further, as shown in the chart below, when broiler progeny of these birds were fed the same diet as their parents (breeders), broilers on the RFC diet contained no evidence of cecal Salmonella. However, 12.5 percent of broiler progeny ceca contained Salmonella when not fed a diet containing RFCS.
The researchers concluded that the supplementation with RFCS prevented cecal Salmonella colonization in the pullets and the organism passed harmlessly through the animal, reducing the odds of infection.
Ultimately, these data from research trials show that you can depend on RFCS to enhance your flock’s health and productivity while reducing the unwanted spread and negative effects of Salmonella.¡
