Abstract
A mixture of predominantly finely divided clay principally consisting of aluminum silicate and sodium bentonite in combination with small amounts of minerals, including iron and zinc, and vitamins, particularly adapted for application to the floor of a farrowing house to prevent knee abrasions to small pigs, to absorb excess moisture, and to provide a food supplement for the baby pigs.
