Application

Nicarbazin is a coccidiostat (antiprotozoal agent) in the poultry industry and is a contraceptive for resident Canada geese and waterfowl. It is used to study avian reproduction and is used to interfere with the formation of the vitelline (yolk) membrane in bird eggs. It has been used to study how delivery method can effect plasma levels of 4,4′-dinitrocarbanilide (DNC), which is the active anticoccidial component of Nicarbazin.

Biochem/physiol Actions

Nicarbazin affects avian reproduction by reducing egg production, egg weight, and egg hatchability. The mechanism of action of Nicarbazin is unknown.

Nicarbazin and halofuginone have been widely used as coccidiostats for the prevention and treatment of coccidiosis in poultry. It has been shown that accidental cross-contamination of feed can lead to residues of these compounds in eggs and/or muscle. This paper

A 56-day floor pen study was conducted to determine the appropriate time to administer toltrazuril (Baycox) (TOL) for control of coccidiosis in broiler chickens. Litter was seeded with field strains of Eimeria acervulina, Eimeria maxima and Eimeria tenella. On Days

A survey was carried out on the occurrence of dinitrocarbanilide (DNC), the marker residue for nicarbazin, in poultry produced in Ireland during 2002-2004. Liver (n = 736) and breast muscle samples (n = 342) were tested. DNC residues were found

Nicarbazin, a coccidiostat, is used as a feed additive in poultry but not in laying hens. Feed contamination may however occur resulting in residues being present in eggs. As a Maximum Residue Limit (MRL) does not exist for nicarbazin residues

A series of studies were conducted to assess the drug sensitivity of 26 coccidial field isolates to the anticoccidial effects of nicarbazin (NIC) and narasin + NIC (NAR + NIC). Isolates were collected from typical broiler farms in the United
