Advantage Forage Enhancer is an inoculant of bacteria and enzymes designed to reduce dry matter loss and maintain high quality haylage and silage. Advantage does this by rapidly dropping pH to inhibit mold and yeast feeding. Less mold and yeast feeding means less heating, dry matter loss and spoilage. This preserves and helps maximize the crop with very high quality feed. Your cows will respond with higher milk production. When forage (mostly alfalfa haylage) is ensiled at a high moisture level (>65% moisture) there is a risk the natural clostridia bacteria in the forage could dominate the fermentation and produce butyric acid as a by-product. Haylage with a clostridial fermentation can be identified by high moisture content, dark green appearance and a strong, offensive butyric odor. Since the production of butyric acid by the clostridia is inefficient, dry matter losses tend to be high and poor palatability makes it difficult to meet the energy requirements of early lactating cattle. To compensate for this energy loss, the cow may enter ketosis, where they metabolize large quantities of fat, putting the cow at high risk for disease and reduced milk yield. The Bacillus subtilis bacteria in the MT550CL is scientifically chosen to handle various strains of clostridia bacteria and reduce their negative effects on the haylage and silage harvested at higher moisture conditions. Highly recommended if you are harvesting under wet and less than ideal conditions. Like all Advantage products, it is designed to protect what you have and maximize your yield.
