Pioneer brand 11A44 Rapid React delivers significant improvement of aerobic stability; it suits situations where grass has very high dry matter and there is a very high risk of aerobic spoilage.
11A44 contains a proprietary strain of Lactobacillus buchneri formulated to dramatically reduce heating in a very wide range of high dry matter silages.
• Reduce dry matter losses by 8% over untreated controls
• Reduce yeasts and moulds to just 0.1% of untreated control silages
• Maintain aerobic stability in maize and cereal wholecrop silage for longer vs treated with 5 litres of propionic acid
11A44 offers a biological solution without the health risk associated with applying acids and acid salts.
• Grass silage 25%-45% dry matter
• Fermented wholecrop cereal silage between 25%-45% dry matter
• Maize silage 25%-45% dry matter
• Crimped maize and cereal gains <65% dry matter
The data shows that high dry matter grass silage treated with Pioneer® 11A44 had significantly greater aerobic stability—around 160 hours—compared to propionic acid treatment (140 hours) and the untreated control (60 hours), highlighting 11A44’s superior ability to resist spoilage.
