BOOR: Harvesting forages for future use

Posted Jul 08, 2021 9:59 AM

Harvesting forages for future use during the winter feeding period or during drought represents a significant cost outlay for cattle operations. Previous research conducted at KSU suggests that large round bales composed of Wheat or Sudan hay can incur feed waste of up to 25% of a bale’s weight when unrolled. Much of this loss can be attributed to factors associated with delayed harvest and/or improper storage prior to feeding. 

Management practices for large round bales 

  1. Make a dense bale. A dense bale will sag less, have less surface area in contact with the ground, shed more precipitation and protect the inner bale from weathering, and make more efficient use of the bale wrap deployed. Bale density is affected by the baler, the experience of the operator, and the type of hay.  
  1. Store bales end-to-end to reduce storage loss. Tightly stacking bales end to end better utilizes the storage area. If bales are not stacked tightly against each other, rain will penetrate the ends and increase damage. Position the hay bales on a well-drained site. A gently sloping site with a southern or southeastern exposure is ideal to maximize solar drying and encourage drainage. To further reduce wastage on the bottom of the bales, some producers have elevated their bales using old tires, shipping pallets or on a layer of 3 to 4 inches of crushed rock. When more than one row of bales is needed, be mindful to space adjacent rows at least 3 feet apart. This simple action will increase air flow and allow the sun to reach the back row. 
  1. Avoid stacking large round bales. Many producers will stack their large round bales in a pyramid formation with the thought of maximizing their utilization of space. However, this strategy will usually increase dry matter losses in the stack as a result of the trapped moisture and reduced air movement. 
  1. DO NOT cover bales. Aside from adding cost, covering bales will potentially trap moisture the same as wrapping them in plastic. If high moisture hay (over 18 percent) is sealed under plastic, quality losses may result from excessive heating and mold development. 
  1. DO NOT store bales under trees. During harvest, many producers will move the large round bales to the field perimeter with good intentions of moving bales to a central location when it is convenient. However, locating bales under trees will encourage degradation of their bales because of trapped moisture and the inability to dry from sunlight. 

Forage production for future use as a consequence of dry weather conditions or winter feeding is an important element for all cattle producers who wish to insure the nutritional needs of their cowherd are being met. Proper attention throughout the entire hay harvesting process, including proper storage will pay future dividends towards this effort.
