Research Report: Apple Cider Vinegar Supplementation in Feeder Pigs

By Meghan Filbert

Apple cider vinegar is held to being a health tonic that promotes beneficial gut bacteria, improves digestion of feedstuffs, enhances performance, and helps decrease parasite load. PFI cooperator, Tom Frantzen, supplemented three groups of pigs with apple cider vinegar and measured feed intake, average daily gain, feed efficiency and return over feed costs compared to pigs not supplemented.

Key findings

  • Pigs supplemented with apple cider vinegar were observed to have a sleeker coat, improved vitality and looked healthier than those not receiving apple cider vinegar.
  • Pigs supplemented with apple cider vinegar tended towards increased feed intake and average daily gains, higher carcass yields, better feed efficiency, and higher profits.


Average daily gains for each rep as well as the mean for pigs fed Apple Cider Vinegar (ACV) and those not (No ACV).
