Perma-Guard Fossil Shell Flour® Anti-caking Agent. Fine powder of microscopic diatom shells. Use as an anti-caking agent for feed and animal bedding.
Many livestock producers swear by diatomaceous earth as a preventive for internal parasite problems; clinical studies do not back this claim, but most animals will consume it freely and it may help improve gastrointestinal health. It is certainly effective on external parasites and to control the growth of maggots under bedding, as the sharp edges of the particles lacerate insects’ bodies and cause death by dehydration.
Wear a dust mask when handling. DE also comes in a pool filter grade which is chemically treated and poses a severe respiratory hazard for mammals, and therefore should not be used. Our natural grade is the right type to use with animals. Do not exceed 2% of total ration.
