The retention of cadmium and selenium influence in fowl and chickens of F1 generation.

The retention of cadmium and selenium influence on Cd retention in the muscle, liver and kidneys of hens, chickens and in eggs was studied. Cadmium (Cd) as cadmium chloride (CdCl(2)) and selenium (Se) as sodium selenite (Na(2)SeO(3)) were added to feed at dosages: group 0-control, group 1-20 mg/kg Cd, group 2-30 mg/kg Cd + 4 mg/kg Se. The birds were exposed to Cd for 8 weeks.

[Long-term exposure to PCB in broiler chickens--metabolic and immunotoxic effects].

Even though it has been forbidden to produce and commerically use polychlorinated biphenyls (PCB) in this country, their stocks and contaminated refuses continue to be a source of danger at present. Hence prevention of environment and food chain contamination is being focused on, along with their monitoring in various commodities. In the poultry operations random contacts of poultry with PCB-containing materials may be expected (paints, plasters, litter).

[Long-term administration of the mycotoxin, ochratoxin A in chickens and the residues in the meat and animal feed].

A feeding trial was performed with chick broilers (cockerels). The feed with an addition of 850 micrograms ochratoxin A (OA) per kg was administered for six weeks. The feeding of the chicks stopped twelve hours before slaughter (in keeping with slaughter technology for chicks).
