About three bushels, distilled.
one gallon equals 8.33 lbs respectively. 5 gallon pail should hold 41.56 lbs considering the rounding up and down on the math.
Hope that helps, Take care and be safe,
30 to 35 lbs. depending on moisture content.
Obviously we all have different size buckets
Some feeder manufacturers must use 6 gallon buckets if a 5 only holds 33 lb.
The one I weighed was 33 pounds.....
