forage quality analysis, since temperatures above 70° C (160° F) can change sample protein and fiber characteristics and digestibility. The basic analytical scheme is to gather a representative forage sample, weigh the sample in its ‘wet’ state, dry the sample to constant oven-dry weight, re-weigh it, and express final dry weight as
Feb 14, 2008 · The carpet is of a substantially uniform thickness that allows for adequate drying of the forage in the drying oven. In one embodiment the forage carpet is about 1 to 16 inches thick. In another embodiment the forage carpet is about 10 inches thick. The carpet may range in width from about 4 to 24 feet depending on size of the drying oven 600 ...
squeeze method. You squeeze the forage into a ball . for 30 seconds and then guess the moisture level. This method is very deceptive and lacks precision. Another way to determine moisture — drying forage in an oven — is time consuming and impractical. Three other methods use specific equipment: the Delmhorst (mention of trade names does not ...
There was also more AIND in heat dried feces, but nitrogen and ash levels were not affected by drying method.

Summary. Accurately determining the moisture content of corn silage on the farm is a challenging process. One of the limitations to on-farm testing is the availability of an accurate scale (+/− 1 gram). In addition, operators need to maintain a consistent protocol when drying samples so that the residual moisture content remaining in the ...
