Leafiness is generally not a concern with grass hays, as grass leaves seldom separate from stems. The general condition of a hay is what is commonly described as the feel and smell of the crop. Coarse texture reduces the palatability of the hay, thereby reducing the amount that will be consumed. The presence of undesirable odors can be indicative of dust and mold problems. Molds can often be detected by odor before visual detection.
Molds can cause health problems to horses.
Purchase hay with a fresh, clean smell. The amount of foreign material present should be considered when selecting hay. Foreign material is simply anything that should not be in the hay. Foreign materials include weeds, stones, small branches, wire or anything else that may be picked up by the baler. Foreign materials may cause a variety of problems.
