Applying a proven silage inoculant at harvest time is an important step. Pioneer offer two distinct types of tested and proven maize silage inoculants: products reduce heating at feed out time and products that improve fermentation quality.

Less heating

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. A paper presented at the New Zealand Grasslands Association conference1, compared the aerobic stability of eight different maize silages inoculated with three 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 silage treated with other products and the untreated control.


Improved fermentation quality

Pioneer® brand 1132 and 1174 improve fermentation quality resulting in a higher drymatter recovery, improved silage quality and more milk or meat for every tonne of maize you ensile. In fact, at a milksolids payout of $6.00 per kgMS, you get back $8.87 for every dollar invested in Pioneer® brand 1132 and $3.59 for every dollar invested in Pioneer® brand 11742.
