Easy horse care using limestone

Routine cleaning is vital for horse health management and critical for adequate disease prevention.  As the experts with the OAHN confirm, horses commonly spread respiratory viruses via nose to nose contact or contact with infectious particles in the environment (tack, grooming supplies, stalls, and trailers). First Saturday Lime’s formula, also known as Precipitated Calcium Carbonate (PCC) is a nontoxic mineral known to:
  • Deodorize
  • Kill parasite larvae
  • Prevent the growth of bacteria
  • Neutralize acid from urine
  • Reduce the likelihood of harboring infections in equine environments

Note: Years of anecdotal evidence from around the world support that in small amounts, First Saturday Lime’s formula is safe for your animal to ingest. How much? Don’t set a bowl of it next to their food but don’t be afraid if some is left over after the applications listed below. Put it this way, it’s made primarily of calcium carbonate, which is regularly used to clean tap water.
