Used extensively worldwide, Nutritech is proud to add MAGNIVA® Classic to its line-up of quality MAGNIVA® inoculants from Lallemand.
MAGNIVA® Classic contains a powerful combination of forage-specific bacteria and enzymes to drive the rapid fermentation and preservation. It also boasts Lallemand Stable Suspension technology, which results in more even and consistent application, a reduced water requirement and reduces the risk of settling or clogging the applicator.
MAGNIVA® Classic is perfect for ‘green crops’ that have difficult ensiling conditions such as pasture and lucerne that is low in dry matter, high in protein, and often high calcium.
Without MAGNIVA® Classic inoculant, these types of silages can be very difficult to ferment and are therefore at risk of significant spoilage. The slower the fall in pH, the greater the risk hat these silages will have poor palatability and low nutrient value.
MAGNIVA® Classic utilises two specifically selected bacterial strains plus high-activity enzymes. The combination of strains drive the pH quickly to completion, above and beyond that of either strain individually. They work together with a specific enzyme package to quickly and efficiently preserve lower dry matter forages as well as forages low in water soluble carbohydrates.
Most other grass-type inoculants on the market only utilise Lactobacillus plantarum. As shown in Figure 1 below, L.plantarum is typically a slow fermenter. Combining L.plantarum with the fast
starting Pediococcus pentosaceous in MAGNIVA® Classic means the pH is dropped earlier and lactic acid content is increased faster, meaning less opportunity for spoilage microbes to take hold in the early stages of fermentation when the silage is most at risk.
Also, the doubling time of P.pentosaceous (strain #12455) is significantly faster than your typical L.plantarum, meaning the 100,000CFU of P.pentosaceous 12455 will outnumber 1 million L.plantarum in less than 4 hours. This is why strain selection is so important, something that Lallemand prides itself on as part of its technical approach to forage.
What’s most important though is the increase in palatability of the silage when fed to livestock. A trial done at the Chrichton Royal farm in the UK showed that feed intakes were significantly higher when they were offered grass silage treated with MAGNIVA® Classic compared to untreated silage. This is where the real return on investment comes when considering whether to treat or not to treat!
| ACTIVE INGREDIENTS | PRIMARY BENEFITS |
|---|---|
| P. pentosaceus NCIMB 12455 | Quickly drives the fermentation, lowering the pH to around 4.5. |
| L. plantarum CNCM MA 18/5U | Drives the fermentation to completion at around pH 3.8-4.0. Dependent on DM. |
| β-Glucanase Xylanase | Helps release sugars from the forage, ensuring a quick fermentation. Helps increase silage digestibility. |

For Manawatu dairy farmer James Anderson, treating silage with the MAGNIVA® range of inoculants is a “no-brainer”. Five years ago he never treated his grass silage with anything. “I always reated my maize, but never my grass” he says.
However, in recent years he decided there was an opportunity to get more milk from his grass silage. Having used Nutritech’s Sil-All®4×4+ for four years, and this last season MAGNIVA® Classic, he has been really impressed with how it has gone. “I’ll keep using it every year now” he says. “It just smells better, it looks better, it feeds better” says James. When asked why, he simply responded “because it works”.
“The grass was really wet when it came in, around 25% dry matter. It was a challenging season for drying down grass” says James. Despite this, the silage treated with MAGNIVA® Classic tested really well, “I think it saved it to be honest,” said James. “To hit a pH of 3.7 on that kind of grass was very surprising. And the cows have loved it, which is the most important thing”. For more information on the MAGNIVA® range of inoculants, get in touch with your local Nutritech Area Manager.
