Aceclofenac Toxicity

Aceclofenac is a type of non-steroidal anti-inflammatory drug (NSAID) that is able to convert into diclofenac, a drug which is thought to be responsible for visceral gout in chickens. This is because chickens are uricotelic and lack the enzyme uricase, resulting in the development of uric acid, which is produced by the liver and excreted through the kidneys. The chicken's blood uric acid levels increase as renal filtration is reduced. Chronic consumption of aceclofenac will induce clinical signs of toxicity in chickens.
