Generic name: Acetic acid (ah-see-tick ass-id) (Vinegar)
Drug class: GI Acidifier, pH modulator
Pharmacology and Mechanism of Action: Acetic acid in the rumen lowers pH by converting ammonia(NH3-) into ammonium(NH4+) ions, which reduces its absorption. Additionally, it may slow the hydrolysis of urea.
Indications and Clinical Uses: Acetic acid is utilized for its acidifying properties in ruminants to treat ammonia toxicosis caused by non-protein nitrogen sources (such as urea poisoning). It is also explored as a potential treatment to prevent the formation of enteroliths in horses by lowering colonic pH.
Contraindications, Precautions: It should not be administered to ruminants until the possibility of lactic acidosis (such as grain overload or rumen acidosis) has been ruled out.
Instructions for Use: use safety precautions to protect eyes and skin. Use stomach tube to prevent GIT mucous membrane irritation.
Horse
-
For enterolith prevention: Administer 250 mL of vinegar per 450 kg of body weight orally once daily.
Ruminants
- For cattle with rumen putrefaction associated with high rumen pH: Administer 4–10 liters of vinegar.
- For the treatment of urea poisoning: Infuse 2–6 liters of 5% acetic acid (vinegar) into the rumen (for cattle); this may be repeated as needed if clinical signs reappear. Recovery typically takes 8–24 hours. A post-recovery probiotic rumen inoculation may improve the gain and productivity of animals affected by urea poisoning.
Patient Monitoring and Laboratory Tests: Because of the unpleasant taste and potential for causing mucous membrane irritation, acetic acid is generally recommended for administration via stomach tube.
Stability and Storage : Acetic acid solutions should be stored in airtight containers.
Drug Compatibility: There are no documented drug interactions with oral acetic acid; however, due to its acidic properties, it could potentially influence the degradation of certain drugs in the gut.
