Starch: Knowing a hybrid’s starch level–or amount of raw food energy–is another key to solving the puzzle of rationing.

NDFd: Is one of the most crucial factors in the TFS-Total Forage System selection process. NDFd 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 NDFd, a cow can consume an additional 0.5 lb in DMI (dry matter intake) and may produce up to 0.53 lb more milk.

Plant Synchronism: Is when the ear and stalk are both at optimal moisture levels at silage harvest time. This unique feature also helps to lengthen the harvest window for optimal quality.

Kernel Texture: Indicates Kernel Density. The less dense the kernel results in higher more efficient digestibility and energy in the silage. All TFS-Total Forage System hybrids have soft kernel textures.

Forage Yield: To qualify for classification as a TFS-Total Forage System hybrid, it must demonstrate extremely high yield for its maturity.
