MAAAX™ LONGfibe™ forage cubes will keep for 10 to 12 months provided they are stored in a dry location out of direct sunlight. If you order one skid you will receive 45 bags that are 50lbs each. The forage requirement of a horse is between 1% to 3% of the horse’s body weight, depending on age (growth stage), activity level and climate that the horse is living in. This last factor would, understandably change with the seasons and housing available at the time. At 1% minimum intake in a warm climate, an average 1000lb horse would consume 73 bags (50lbs) per year; therefore, one skid of 45 bags would last approximately 7.5 months at the minimum intake of 1%, or approximately 2.5 months at 3%.
