We sell both ground wood and gypsum for animal bedding. All of our ground wood is unpainted and untreated, and the gypsum drywall comes to us as unpainted scrap from new builds. Customers are able to purchase wood, gypsum or a mixture of the two by the yard.
Some organic bedding materials support conditions which are more ideal for pathogenic growth than gypsum bedding. Using mineral bedding will decrease teat end exposure to environmental mastitis pathogens. Dry matter content of most organic material is often less than 70% versus greater than 90% for gypsum bedding. Besides that, drier bedding will result in fewer flies, slip resistance and an odor free area.
