With maize silage harvest fast approaching, it’s a good time to prepare a management plan that maximises maize silage quality and reduces storage and feed-out losses.
The checklist below outlines some of the important steps in preparing for maize silage harvest:
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 to improve fermentation quality and products to reduce heating at feed-out time as well.
Maize silage contains a high concentration of starch and sugars which 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.
Silage inoculated with Pioneer brand 11C33 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.
Pioneer brand 1132 and 1174 improve fermentation quality resulting in a higher drymatter (DM) recovery, improved silage quality and more milk or meat for every tonne of maize ensiled. In fact, at a milksolids payout of $6.25 per kgMS, you get back $9 for every dollar invested in Pioneer brand 1132 and $3.78 for every dollar invested in Pioneer brand 11742.
