Round-bale Feeders Reduce Waste and Increase Intake
A study done at the University of Minnesota revealed the following interesting facts:
Feeding round bales without a feeder (placing them directly the field) results in 60% of the hay being wasted.
Placing round bales in a feeder reduces losses to between 5% and 30% depending on the design of the feeder.
Horses fed from feeders tend to consume more hay. Feeder-fed horses ate 2% to 2.4 % of their body weight in hay, while non-feeder-fed horses only ate 1.3% of their body weight.
This study shows that horses eating round bales not placed in a feeder may have trouble meeting their energy requirements even when hay is present.
Round-bale feeder design affects hay waste and economics during horse feeding.
