Question: We are having a hard time finding small-square bales and as a results, are going to start feeding round-bales. How many small square-bales are in a round-bale?

Answer: It depends on the weight of both the large and small-square bales. For example, if the round-bale weighs 1,000 pounds, then 20, 50-pound small-square bales would be equivalent to 1 round-bale. If the large round-bale weighs 1,200 pounds and the small-square bales weigh 40 pounds, then 30 small-square bales would be equivalent to 1 round-bale. It important to know the weight of hay bales both for feeding and economic purposes.
Keeping in mind that storage and feeding losses associated with round bales are typically higher compared to small square bales. Especially when storing bales outside and feeding without a hay feeder.
