Injurious matter is material that is poisonous or will harm the animal when eaten. Don't buy hay containing injurious foreign material. Generally the smell of new mown hay is used as the standard for comparisons. Off-odors, such as mildew, mustiness or putrefied or rotten odors, indicate lowered quality and acceptance by livestock. These smells are caused when hay is stored at too high moisture or has been weather damaged.
Hay condition is important.
Hay should be free from must and mold and from insect and disease damage. It should also be free of dust. Early heading or bloom 2.
