The difference is when it kicks it and for how long. Long-term disability insurance only kicks in after an elimination period (a.k.a. a waiting period). The typical elimination period is 90 days, but can be as long as 180 or 360 days depending on your policy.
A barn is an agricultural building usually located on farms and used for various purposes. In the North American area, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, sheep barn, potato barn.
MN Statute 16B.60 Subd. 5 states, Agricultural building means a structure on agricultural land as defined in section 273.13, subdivision 23, designed, constructed, and used to house farm implements, livestock, or agricultural produce or products used by the owner, lessee, and sub lessee of the building and members of their immediate families, their employees, and persons engaged in the pickup or delivery of agricultural produce or products.
