SiloSolve® MC boosts fermentation and preservation of barley silage

A recent European study shows that SiloSolve® MC keeps barley silage better for longer, resulting in less feed spoilage and higher dry matter recovery.

Conducted at the Lithuanian Institute of Animal Science, the controlled field trial was designed to evaluate the effect of SiloSolve® MC on fermentation and preservation of barley silage, as indicated by aerobic stability. SiloSolve® MC is a silage inoculant that contains three strains of lactic acid bacteria, which improve fermentation by reducing pH and limiting the growth of spoilage microorganisms.

“Data from this study show that SiloSolve® MC meaningfully boosted silage fermentation, aerobic stability and dry matter recovery” says Product Manager Mai-Brit Voss. “For producers, that means higher returns through better quality and preservation of silage, less feed waste, and better dairy cow performance.”

Study design

In the study, whole crop barley silage with a moisture content of 59.9% was chopped to approximately 0.8 inches and ensiled in mini silos for 120 days at 68°F. The silage was divided into two treatment groups, each with five replicates: one with untreated barley and the other with barley inoculated with SiloSolve® MC at a dose of 150,000 cfu/g of fresh forage. 

At day 120, investigators evaluated aerobic stability and dry matter content. Aerobic stability is determined by monitoring the temperature increase in silages stored in insulated PVC-tubes at 68°F ambient temperature.

Results

Results show that silage treated with SiloSolve® MC had less spoilage, with 99% less yeast, 95% less mold, and 30% lower ammonia-N levels than control. This resulted in a significant increase in dry matter recovery in the SiloSolve® MC-inoculated silage of 2.5 percent point (Tables 1 and 2).

In addition, the lower spoilage in the SiloSolve® MC treated silage led to an aerobic stability improvement of 66 hours, or 2.7 days. While the control silage exceeded the ambient temperature by 5.4°F after 186 hours of aerobic exposure, indicating degradation, the SiloSolve® MC-treated silage exceeded ambient temperature after 252 hours (Figure 1).

“By improving fermentation and increasing aerobic stability, SiloSolve® MC produces higher-quality barley silage that stays fresh for longer,” Voss says. “That means less waste and significant economic benefits for the producer.”
