2008 Dairy Performance Hybrids

Hubner's DPH hybrids have been selected for both their high-performance agronomic traits and quality nutritional feed values. You'll find they are all above average in yield and high in NDF (neutral detergent fiber) digestibility.

All DPH hybrids in the Hubner lineup are dual-purpose hybrids and can also be harvested for grain and high-moisture corn, if necessary. They're likewise available with various kernel textures to allow optimum starch availability with your animals' current forage diet.

Hubner Seed annually evaluates the performance of its DPH hybrids through several silage and grain plots. The plots are located in six states covering many maturities, soil conditions and weather patterns. Data collected from these plots include yield (forage and grain), mini-silos (for silage quality), resistance, standability and kernel texture.

In 2006, Hubner began to enrich its silage performance data by sponsoring the Milk Max™ silage research program. Now in it's second year in 2007, Milk Max generates on-farm comparison data of various brand hybrids grown and harvested by real dairy farmers across the United States.

DPH Selection Criteria

Yield: A Hubner DPH hybrid must demonstrate an above-average yield for its maturity.

dNDF: This is the most important criteria in Hubner’s DPH selection process. dNDF is the percent of a corn silage hybrid’s NDF (neutral detergent fiber) that digests inside the rumen within the first 30 hours after consumption. For every one unit increase in dNDF, a cow can consume an additional 0.5 lb in DMI (dry matter intake) and may produce up to 0.53 lb more milk.

NDF: The level of fiber in a DPH hybrid helps us determine if the hybrid fits better in a high corn silage or a high haylage-type feeding ration. NDF runs separately from dNDF, so you can have high NDF corn silage and it still will be high in dNDF.

Lignin: This is the undigestible portion of fiber inside a corn silage hybrid’s total NDF. Knowing this figure, your Hubner advisor can determine if a given hybrid fits better in a high corn silage or a high haylage feeding ration. Conventional wisdom says lower lignin means better feed quality. However, researchers are finding that low lignin hybrids do not actually feed better than higher lignin hybrids with high overall NDF.

Lig/NDF: Using a formula—lignin divided by NDF multiplied by 100—Hubner can calculate how “lignified” the corn silage hybrid’s total NDF is. A figure of 6.0 or lower is considered excellent and translates into high DMI (dry matter intake) potential.

Starch: Knowing a hybrid’s starch level—or amount of raw food energy—is another key to solving the puzzle of rationing. High starch hybrids serve best when incorporated into a high haylage diet. However, they also serve well in high corn silage diets, with the understanding that it may require pulling dry grain or HMC out of the total feed ration.

Kernel Texture: The softer the kernel, the more available the starch is to the cow. Knowing which hybrids have a soft, medium or hard kernel texture indicates the need for kernel processing and calls out those hybrids that can offer maximum grain harvest if necessary.

IVTD: This is another corn silage hybrid energy measurement. It is calculated based on both the starch content and digestible fiber (dNDF) of a hybrid, yet does not distinguish which of the two factors contribute the most. Two IVTD figures can be the same, with one based on a high starch and the other on high dNDF. Either way, a high IVTD rating represents a cow’s highest potential for milk production.
