It is a natural product that is sterile, chemically inert and resistant to mould and fungus. Perlite is used in breeding as an excellent carrier for liquid feed additives, such as drugs, antibiotics or vitamins. Due to its high absorbency, perlite, like a sponge, soaks up the medication that is given to the animals with their food. The medicinal substance is then gradually released in the animal’s body and the perlite is excreted. Perlite is a harmless material, which additionally helps to cleanse the digestive system of the animal in question. Perlite is also used in animal feed as a natural anti-caking agent and on farms as an odour and moisture absorber in bedding.
