Which Com Silage Hybrid Is Best for You? A corn hybrid that's best for grain yield may not be the hybrid that produces the best silage for livestock, according to research conducted by Cargill. For example, dairy cows need corn silage hybrids that can provide a high percentage of digest ible fiber to help achieve top milk production and milk test. Beef cattle on a fattening program need a daily ration with a high energy density for fast weight gain.

We have evaluated our hybrids and identified those that tested highest in key silage traits. Use the Menu to make corn silage decisions. Grain Yield rates hybrids on their grain production ability, adjusted to 15.5 percent moisture within a maturity range. Compare these ratings with silage tonnage and whole plant quality ratings and you will see differences. Silage Tonnage rates hybrids on their ability to con sistently produce high tonnage yields within their maturity range. Results of on-farm and research plots (80+ locations 1988-89) were summarized and corrected to 70 percent moisture. This enables us to analyze hybrids for silage tonnage in the same manner we do for grain yield. The following whole plant quality characteristics are important. Digestibility rates whole plant digestion and energy density This is an accurate indication of a hybrid’s total energy potential. intake Potential rates the fiber digestibility, a factor that affects potential intake of a ration. This is essential for top milk production. Crude Protein rates the content of the whole plant to con tribute crude protein to a ration.
