Nicarbazin is an anticoccidial medication used primarily as a feed additive for poultry, especially meat chickens. Its active ingredients, 4,4'-dinitrocarbanilide and 2-hydroxy-4,6-dimethylpyrimidine, work synergistically to halt the life cycle of the protozoan parasite Eimeria, preventing coccidiosis from damaging the poultry's intestinal lining. This drug, approved by the FDA, also functions as a contraceptive in pest bird species like Canada geese and feral pigeons, contributing to their population management.
Nicarbazin contains several impurities and related compounds. The 4,4′-dinitrocarbanilide component makes up about 40% of the blend, while 2-hydroxy-4,6-dimethylpyrimidine constitutes the remaining 60%. Impurities in Nicarbazin may include traces of unreacted starting substances, such as 4,4′-diaminodiphenylmethane or dimethyldicyanoquinonediimine. The compound also contains related substances like dimethylpyrimidine, monohydroxypyrimidine, and their hydronitro derivatives. The quantities of these substances are kept at minimal levels to reduce toxicity and enhance the safety of Nicarbazin.
Nicarbazin is not intended for human use. The drug poses potential risks if consumed, including thyroid changes, changes in body weight, and skin sensitization. Long-term exposure could lead to liver and kidney damage. Always ensure adherence to safety procedures when handling Nicarbazin.
Nicarbazin is safe in food, provided it is used within the recommended dosages and withdrawal periods. The FDA has established tolerance levels for Nicarbazin residues in poultry tissues: 200 parts per billion in edible tissues and 400 parts per billion in poultry liver. Exceeding these established levels could pose risks to human health.
No, Nicarbazin is not an antibiotic. It is a type of compound called a coccidiostat that specifically targets the coccidia parasites in poultry to prevent coccidiosis disease.
“Nicarb” refers to Nicarbazin, an anticoccidial drug commonly added to chicken feed. It helps prevent the onset of coccidiosis, a parasitic disease that can cause serious harm to chicken populations. By including Nicarbazin in chicken feed, poultry farmers can ensure healthier, more productive flocks.
