With so much being written these days about floury grain, what do we really know? Is it advantageous, and if so, why?
Most corn grown across the nation has high test weight corn kernels that are hard, heavy and slick. These heavy, dense particles move quickly through our animals leaving much undigested energy in the manure. Floury corn, on the other hand, is softer and the travels through digestive tracts at a much slower pace. This slower passage rate allows for more complete energy absorption.
According to starch digestibility testing at our countries best laboratories, floury hybrid corn is up to 50% more digestible. Starch digestibility (IV7SD) is measured in-vitro or occasionally in-situ (in rumen fluid) so for cattle HUGE differences are measured. An example: It would require 15lbs of vitreous (hard) corn to feed equally with 10lbs of floury (soft texture) corn.
What about comparing vitreous corn to floury corn for swine and poultry? So far, we haven’t found differences in hybrids as great as that with cattle. However, in research through lab analysis with an enzyme bath that simulates a pig’s digestive system we have noticed 10-15% improvements in feed efficiency. Studies also show 3-5% improvements in energy uptake in poultry. These findings were through rooster assays and broiler trials.
There are currently precious few corn companies with the genetic base and resources to create new hybrids for this market challenge. We take pride in being a company that meets this need. Our focus is only livestock grain and silage, and promise to keep it that way for generations to come.
