PorcBoost® EB reduces E. coli-induced diarrhea piglets

News   •   Nov 28, 2016 06:00 GMT

PorcBoost® EB — Chr. Hansen’s new probiotic feed supplement for suckling and weaned piglets — has been shown to inhibit the proliferation and harmful effects of pathogenic E. coli, the leading cause of diarrhea in piglets.

Chr. Hansen scientists carefully selected the novel strain of Bacillus subtilis in PorcBoost® EB based on its E. coli-inhibiting properties and demonstrated safety in weaned piglets. Studies show that it reduces the severity of E. coli-induced diarrhea, thereby decreasing related mortalities and performance losses.

“Pathogenic E. coli is the most prevalent cause of diarrhea in piglets, which causes devastating losses due to increased mortalities and reduced economic performance,” says Jens Joergensen, Chr. Hansen’s global product manager for swine. “The unique B. subtilis strain in PorcBoost® EB is scientifically proven to limit the growth and negative effects of E. coli in the intestine, resulting in reduced diarrhea and improved livability and performance.

“As the industry comes under pressure to limit antibiotic use, PorcBoost® EB offers producers a completely natural and highly effective solution for managing E. coli and optimizing performance in piglets, both alone and in combination with other probiotics, antibiotics and other common feed additives.”

PorcBoost® EB supplementation significantly reduced scours (diarrhea) in weaned piglets. Preliminary study data is shown in the graph below (Figure 1), in which E. coli-challenged weaned piglets supplemented with PorcBoost® EB have virtually the same fecal scores as weaned piglets without E. coli challenge.

Proven mode of action

The livability and performance improvements observed in these studies are consistent with PorcBoost® EB’s proven E. coli-inhibiting mode of action. In addition to inhibiting E. coli growth in vitro (Figure 2), the strain shows excellent adherence to swine intestinal epithelia, thereby reducing intestinal adherence of E. coli by up to 97% (Figure 3).

Maximum flexibility

PorcBoost® EB can be used with a wide range of feed additives and survives pelleting temperatures up to 203oF, offering maximum flexibility in feed formulation. In addition to being compatible with antibiotics, organic acids, zinc oxides and copper, the all-natural, non-GMO product is synergistic with other Chr. Hansen probiotic strains, enabling the possibility of effective combined use.
