A 100-Year Review: Total mixed ration feeding of dairy cows
Total mixed rations (TMR) as we know them today did not exist in 1917. In fact, TMR are an invention of primarily the last half of the past 100 yr. Prior to that time many dairy herds were fed only forages, but dairy producers started moving toward TMR feeding as milk production per cow increased, herds became larger, freestall and large-group handling of cows …

Importance and progress of corn silage kernel processing
Bottom line: If improved kernel processing reduces fecal starch from 5 percent to 1.5 percent, there is energetic potential for an additional 2.52 pounds of milk from the same corn silage. Dr. Dave Mertens, formerly of the U.S. Dairy Forage Research Center, developed the laboratory methodology to evaluate corn silage kernel processing.

Corn silage feeding guidelines for dairy production
Corn silage should be primarily fed based on its carbohydrate contribution for meeting energy needs of cattle. This is because 70 to 80 percent of nutrient makeup in corn silage is carbohydrate from neutral-detergent fiber (NDF), starch and sugars. Many producers value corn silage for its protein contribution. However, the average crude …

A smooth transition to new corn silage: Focus on starch digestibility
The Penn State particle size separator is a great tool to help you assess particle size distribution of corn silage. Most labs can run a kernel processing score (KPS). Degree of kernel processing can have a big effect on starch digestibility. A KPS under 50 suggests that the silage is under-processed; scores 50-70 are adequately processed.

Forage specialists advise a short length of chop without a kernel processor or a longer length of chop if a kernel processor is used. A general recommendation is to chop corn silage with a chop length ranging from .50 to .75 inches if not kernel processed at harvest, or 1.00 to 1.50 inches if a kernel processor is used. 3.

Joe Lawrence and Allison Kerwin. The value of whole plant corn as a forage (corn silage) can largely be categorized by two contributions to animal nutrition: fiber and starch and the digestibility of each. In terms of starch, focus is often on total content and digestibility. However, kernel processing addresses a third factor: accessibility.
