BREAKING DOWN 'Unintentional Tort'. In certain cases, a person causing an accident may be held legally responsible for their negligence and may have to pay a plaintiff for physical injuries, property damage and/or financial loss.
Straw is normally used for a bedding material, while hay is used as a feed supplement. Straw is dried out and works well for building nests and providing cushioning for animals to sleep in. It is not moist like hay and is unlikely to mold.
There is not really much difference, except in the name and the way it is used. Haylage means ensiled forages, made up of grass, alfalfa and alfalfa/grass mixes. Silage usually refers to ensiled grain crops like corn and sorghum. Both are technically silage.
