New Zealand inoculant research

Maize silage contains a high concentration of starch and sugars. This makes it more prone to heating when the stack or bunker is opened at feed-out time.

When silage heats it loses valuable nutrients which could have been used by the cow to produce milk. By applying the right silage inoculant and using good harvest, storage and feedout management techniques you can reduce heating in your maize silage.

A recent paper presented at the New Zealand Grasslands Association conference2, compared the aerobic stability of eight different maize silages inoculated with a range of commercially available silage inoculants.

Pioneer® brand 11C33 inoculated silage stayed cooler 55.5 hours longer than the untreated control. There was no significant difference between other products and the untreated control.
