Corn silage has been called the king of stored forages for good reason. Dry matter yields and milk production potential per acre consistently surpass other forage crops while allowing farmers to harvest large amounts of quality feed over a relatively short harvest period. Corn raised for silage can be used in combination with other forage crops to allow for the implementation of double or even triple cropping systems. Thus, increasing the number of dairy cattle supported by each acre of farmland and increasing utilization of nutrients applied to soils through manure applications (i.e., phosphorus). Seed companies have improved the genetics of corn hybrids used for silage, especially as they relate to NDF digestibility. These genetic improvements have increased the nutritional value of these crops, which is even more important under the extended heat stress conditions and resulting decreased dry matter intakes of the Southeast. Environmental temperatures in excess of 32°C and limited rainfall during tasselling and pollination decrease grain development in the corn plant, resulting in a lower energy crop and presenting challenges for meeting the energy needs of high producing dairy cows. Harvesting corn for silage at the proper dry matter content and particle size can affect packing density and quality of silage available at feedout. Starch digestibility can be improved with the proper use of kernel processors on silage choppers. Silage management at harvest and feedout also affects feed quality and dry matter losses.
