Molecular effects of nicarbazin on avian reproduction.
Nicarbazin (NCZ) is an anticoccidial drug routinely used in the poultry industry that can negatively affect reproduction by reducing egg production, egg weight, and egg hatchability. The molecular mechanisms by which NCZ affects reproduction are unknown. Lipoprotein lipase, vitellogenin, transglutaminase, and calcium are all involved in egg formation and embryogenesis. Therefore, in vitro assay...
متن کاملDetermination of the residue levels of nicarbazin and combination nicarbazin-narasin in broiler chickens after oral administration
The depletion times of the anticoccidial nicarbazin administered individually and of nicarbazin and narasin administered in combination were evaluated by determining the presence and levels of 4,4'-dinitrocarbanilide (DNC), the marker residue for nicarbazin, and narasin residues in the muscle tissues of broiler chickens subjected to a pharmacological treatment. A high-performance liquid chromat...
متن کاملComparison of nicarbazin absorption in chickens, mallards, and Canada geese.
Nicarbazin (NCZ), a coccidiostat commonly used in the poultry industry, causes reduced hatchability and egg quality in layer hens at a concentration of 125 ppm (8.4 mg/kg) in the feed. Although this effect is undesirable in the poultry industry, NCZ could provide a useful wildlife contraception tool for waterfowl, particularly urban geese. We tested the absorption of NCZ in chickens (Gallus gal...
متن کاملDrugs in feeds.
The method for sulfamethazine using post column derivatization (Associate Referee Robert Smallidge) was adopted First Action in 1999. There are a number of methods which could be readied for collaborative study with relatively little work, i.e., carbadox, ethopabate, lasalocid, or morantel tartrate. In addition to the remarks made for the following Associate Referee topics, readers can refer to...
متن کاملMycotoxins in Aquaculture Feeds
Mycotoxins are toxic chemicals produced by certain species of molds usually belonging to the Aspergillus, Penicillium or Fusarium genera. The importance of mycotoxins to aquaculture and animal agriculture first became apparent during the early 1960s with outbreaks of aflatoxicosis in young turkeys in the United Kingdom and hatchery-reared rainbow trout (Onchorynchus mykiss) in the United States...
