Squeezing a handful of chopped maize can help estimate possible DM%. This won't replace laboratory or microwave methods for DM% measurement.
Check length of ‘average’ chopped plant material. Very occasional longer leaf pieces are not unusual.
Chop length can be adjusted for maize crops that are harvested too wet or too dry.
Target pieces smaller than tip of your little finger. Larger pieces increase problems of air exclusion from the stack
lacing the silage sample in a bucket of water, allowing the cob/stover to float off, then pouring water out can leave kernels at the bottom to improve the speed at which kernel processing can be checked.
Sort chopped material, checking for:
Cattle cannot digest unprocessed kernels so aim for more than 95% of kernels to be crushed/cracked.
