Hay & Feed Testing and Options Workshop #3 Mandy Blocker Muskogee Co Ag Educator Pamela Ward McIntosh Co Ag Educator Tony Yates Sequoyah Co Ag Educator High Quality = Timely Management Quantity: Rainfall, Temp. Variety Time of Harvest Fertility Quality: Rainfall, Temp. Variety Time of Harvest Fertility #1 Factor? #1 Factor? For cow hay, we want enough quality to maintain the cow during the winter feeding period with the least amount of supplemental grain. DRY COW: 8% protein, 54% TDN minimum LACTATING COW: 10% protein, 58% TDN minimum Plant Maturity Stages For Bermudagrass, this is going to be 4 to 6 weeks. Reprint from MSU Forage News. May 2009 1

Huhnke. Assuming $57 bale cost ($100/ton), loss is $20/ton by winters end! With 200 tons mowed, $20 loss/ton x 200 tons = $4000 x 10 yrs = $40,000 *This would build a 50x75 metal barn to store all hay with a life of 30 years plus! 3
Weather Weather damage damage to hay to hay stored stored outside outside depends depends on: on: Bale Bale storage density/shape method (ability to shed rain) stored This bale on ground: is coarse 43% stemmed, handling+storage lumpy, waste and squatted stored These on are wooden recipes rack: for 31% disaster! handling+storage waste Note dark areas of water infiltration Weather damage to hay stored outside depends on: Storing method and location Bales are not butted together on ends, are on a flat, poorly drained site, rows are too close together and run east/west Weather damage to hay stored outside depends on: Storing method and location Bales are tightly butted together on ends to shed rain Stored on a south exposure slope that is well drained North/south Rows are 3-4 feet apart to allow wind/south sun to enter These rows were baled in Aug. 2008 Notice the outer deterioration, but netwrap holding a nice tight circle. Feed your low quality, old, and exposed hay first before bad weather arrives!! Note beginning water marks on west side of this bale Baled in June 2009 4
Hay sheds allow you the option to carryover surplus hay. To the left of the green line is fertilized Bermuda hay that is 2 years old. To the right is Ryegrass and Berm from last year. Quality and DM loss is minimal. Since the hay was not used last winter, the producer only cut one 10 acre field of fertilized Bermuda this year. Similar hay barns would allow you to select ideal rainfall (years), and condense resources without the fear of running out of hay. This saves money and lessens drought effects.
