Reducing Hay Waste When Supplies Are Low

After two years of droughts in Missouri, hay supplies are low, with many producers feeding hay during the summer months and lacking the pasture growth to get the tonnage comparable to previous year’s hay crops. Many producers in southern Missouri reported 50%-75% reductions in first-cutting hay crops in 2023. With such a low availability of hay in the state and high input costs, the price of hay has increased, which adds insult to injury for livestock producers. Minimizing hay waste should be at the forefront of the minds of producers this winter.

Here are some tips to reduce hay waste:

• Reduce waste from rot caused by outside storage
  • Storing hay inside a barn is the gold standard for storage. If hay is not rained on, it will maintain its quality indefinitely apart from vitamins A and E, which can reduce slightly over time. When hay is stored outside and allowed to be rained and snowed on, spoilage occurs on the outer edge of the bale. Even a couple inches of external spoilage can account for major losses of valuable hay for livestock.
  • While reducing loss during storage is important, not all farms have adequate barn storage for all of their hay. In this case, producers should consider how they can minimize moisture exposure on the top of bales as well as from the ground.
  • Stacking bales in a pyramid shape and covering with tarps is a great way to reduce weathering from rain and snow. Also, storing bales on pallets, railroad ties, or a raised gravel or concrete pad is an excellent way to reduce spoilage of the bale from ground moisture. Further, if storing round bales in rows, farmers should leave a few feet in between the rows to allow for better airflow and to prevent rain pooling and seeping into the bales when the rounded edges of the bales are touching.
• Consider hay feeders or unrolling
  • Most farmers would agree that giving any type of livestock access to a bale of hay without a feeder leads to more waste. Research shows that feeding without some type of hay feeder can result in upwards of 45%-57% wastage, depending on the class of livestock and the number of animals. While there is a plethora of hay feeders available at varying price points, using any type of hay feeder will reduce hay waste compared to no feeder. Within the many round bale feeder options, choosing a ring that has an enclosed bottom or one that suspends the bale off the wet ground will help reduce waste.
  • Some producers prefer to unroll their hay on their pastures. This is an excellent option for more evenly distributing hay waste and manure across the pasture. Taking advantage of this fertilizer wrapped up in net wrap can make improvements to the soil over time. However, when multiple days’ worth of hay is unrolled at once, unrolling hay can have upwards of 40% waste. Producers should consider unrolling only one day’s worth of hay at a time, reducing that waste to around 12%.
