A relatively new way of processing corn silage, which shreds stalks, effectively crushes kernels and is said to contribute to a 2-lb/cow/day milk increase, has been a real pain for the custom forage harvesting business.
Shredlage requires a whole new set of processing rolls. As many custom operators can attest, it slows down harvest and has caused extra wear and tear on choppers.
But dairy-producer clients are telling them that this method, which shreds silage corn longitudinally at 26- to 30-millimeter lengths, is how they want their crop harvested.
Many are finding the feed’s longer particle lengths provide enough fiber, and its smashed kernels enough starch, to replace some purchased feeds, including dry hay. Some also say the highly digestible feed has increased their herds’ milk production.
And some have told their custom harvesters, if they don’t get on board with Shredlage, they’ll lose business.
The new crop-processing method is causing quite a sensation – as well as consternation – amongst dairy producers, nutritionists, forage harvester manufacturers and custom operators. Shredlage is bringing about a revolution in how corn silage is harvested and used.
The rolls are the brainchild of Roger Olson, a nutritionist, and his father Loren, an inventor
