\r\n
\r\n When forage or hay quality drops below the minimum nutritional requirements for beef cattle, producers usually utilize corn to satisfy their energy requirements. As corn prices rise, Arkansas producers are utilizing high quality bermudagrass hay as an economic feed option. By participating in hay shows, hay analysis programs and forage production meetings, producers have improved their ability to produce quality bermudagrass hay. In a study that was conducted in Logan and Johnson Counties in 2010, 78% of the bermuduagrass hay had an average analysis of crude protein (CP) 13.2% and total digestible nutrients (TDN) 64.1%. Hay of this quality can supply the nutritional needs of most Arkansas cattle herds without any additional supplementation. If you compare the cost of corn and high quality bermudagrass hay based on energy value, the bermudagrass is a much more economical option. Corn has a TDN of 90% and is currently selling for $240/ton. Bermudagrass with a TDN of 64.1% has a TDN value of $170/ton compared to corn. Since a 900 lbs bale of hay usually sells for $30 – $40 the energy cost would be one half that of corn. Producers have learned to compare energy costs to reduce their feeding expenses.
