Grain Yield vs. Energy Indicators
SEEDWAY® conducted research on paired grain/silage harvest trials across 28 hybrids at the same location to look at grain yield versus energy potential. These trials included a diverse cross-section of genetics with silage harvested at a uniform 35,000 silage and 32,000 grain population.
Something To Chew On. The Science of Silage.
We’re passionate about our own product research and development and have conducted product testing for over 29 years. We also keep a close eye on the academic and industry research targeted at optimizing milk production and herd health in high producing dairy cows.
According to Dr. David Coombs of the University of Wisconsin, fiber has a bigger impact on milk production (6-7 lbs per cow) than starch (3-5 lbs. per cow).
Studies show that feed and cow factors are required to measure true fiber digestion. Current laboratory nutrient content processes are a good start on quality analysis. However, three fiber issues must be accounted for in determining net fiber quality: potential fiber digestibility (pdNDF), rate of fiber digestion (kd), and rate of fiber passage (kp).
Is an evaluation of grain starch in silage an easy swallow?
The grain portion of silage is perceived to be nearly all digestible and therefore important in selecting hybrids for silage with higher energy potential. Selecting on the basis of grain percentage is misleading as it does not consider the contribution of fiber and sugar to energy. And, while often ignored, grain composition itself is variable.
The critical piece of starch understanding is to know that starch content at dough, half milk and black layer maturity phases vary significantly within the same variety and management setting. Maturity/moisture at harvest is important to obtain optimum feeding characteristics for every corn silage.
The management contribution to feeding quality is actually larger than the genetic contribution. The simplest way to capture the most quality is to harvest all the acres at the proper dry matter, 35%-40%
