Corn silage is an important feedstock for cattle producers across the Great Plains.
Desirable corn products should produce high tonnage with favorable silage quality characteristics.
In this study, the objective was to provide insights to farmers on which of the 22 corn products evaluated have high tonnage and good silage quality characteristics.

The study was set up as a randomized complete block with three replications.
Twenty-two corn products were evaluated.
Corn was sprinkler irrigated and weeds were controlled as needed. No fungicide or insecticide was applied.
Silage quality was sampled for each corn product at ½ milk line. Sampling dates varied by relative maturity, but all sampling occurred in the last two weeks of September.
Corn products were hand-harvested about 4 inches above the soil surface to provide a representative sample and were then chopped with a silage chopper.
A subsample of the freshly-chopped material was collected and sent to Dairyland Laboratories Inc. for silage quality analysis.
Total biomass was collected, weighed, and tonnage was determined for each corn product.
Producers should work with their local seed sales team to identify how their branded corn products performed in this study.
