Investigation of the serum oxidative stress in broilers fed on diets supplemented with nickel chloride

The purpose of this study was to investigate the serum oxidative stress induced by dietary nickel chloride (NiCl2) in broilers. A total of 240 one-day-old avian broilers were divided into four groups and fed on a cornsoybean basal diet as control diet or the same basal diet supplemented with 300 mg/kg, 600 mg/kg and 900 mg/kg NiCl2. During the experimental period of 42 days, oxidative stress parameters were determined for both control and experimental groups. The results showed that malondialdehyde (MDA) content was significantly higher (p 2 in excess of 300 mg/kg could cause oxidative stress, which could finally impaired the antioxidant function in broilers.
