New silage inoculant MAGNIVA® Platinum proves to be popular in the field

Last season New Zealand farmers and contractors had the opportunity to try the new live bacterial forage inoculant, MAGNIVA® Platinum. Feedback on the new Lactobacillus hilgardii bacteria has been overwhelmingly positive, with the unique combination of bacteria and enzymes in MAGNIVA® Platinum having a noticeable effect on silage quality, palatability and temperature.

According to Manawatu dairy farmer James Anderson, “it is excellent stuff”. He says, “the stack face was open for five days in poor weather before we got across it and there was no heating in the face or on the sides at all. Palatability has increased; the cows just love it”.

Soon to be married, Canterbury-based couple Catherine and Patrick of Nagle Contracting used MAGNIVA® Platinum on maize and lucerne silage for the first-time last season. They were “really impressed with how quickly we could open the stacks and how much cooler this silage was”. They were so impressed with how well it worked on the maize that they’ve used it on this season’s whole crop harvest and plan to use it on all of their crop and maize this year.

MAGNIVA® Platinum is scientifically proven to significantly improve the quality and aerobic stability of maize, whole crop cereal and other silages prone to heating. Using MAGNIVA® Platinum it is safe to open stacks at two weeks rather than waiting six weeks for any inoculant that relies on L. buchneri as its primary bacterium to keep silage cool. Opening time is essential when we consider what one month’s worth of feed is worth, especially in dry conditions or for autumn calving herds who often need maize soon after ensiling.

“Aerobic stability” is measured as the time for silage temperature to increase by 2 degrees. After 15 days of fermentation, silage treated with MAGNIVA® Platinum has 18 hours longer aerobic stability than silage treated with L. buchneri alone. At 30 days, it has 24 hours extra aerobic stability. Those extra hours of cool silage minimise silage losses when your stack face is open or fed out in advance.

MAGNIVA® Platinum combines the patented L. hilgardii CNCM I-4785 bacterial strain with the already proven L. buchneri NCIMB 40788 strain from Lallemand. These two bacteria working together synergistically provide cooler silage faster than the individual bacteria used in isolation. MAGNIVA® Platinum also utilises the ‘fast starting’ bacteria Pediococcus pentosaceous strain and enzymes to help improve silage digestibility and fermentation. Cool silage means less dry matter lost, more metabolisable energy retained, less yeast activity and less mycotoxins. MAGNIVA® Platinum significantly improves long-term silage stability, so even in stacks that are not opened early, the aerobic stability benefits get more significant with time.

For farmer James Anderson, the economics stack up. “It does seem like a lot of money to spend initially, but now that I have used it and seen how well it works, I wouldn’t ensile maize without it”.
