The aim of the current study was to investigate the concentrations of ceruloplasmin, copper, iron, zinc and cadmium concentrations in blood serum and seminal plasma obtained from Merino rams. In addition, their relationship with sperm parameters, fertility rate and litter size were also studied. Blood and ejaculate samples (6 replicates) were taken in October from 19 Merino rams, aged between 18 and 24 months. Ceruloplasmin, copper, iron, zinc and cadmium in blood serum and seminal plasma were determined. Sperm parameters including volume, mass motility, motility, concentration, Hos-test, viability, abnormal sperm and acrosome abnormality in semen, fertility rate and litter size were also evaluated. Highly positive correlation was found between blood ceruloplasmin and blood copper concentrations (r=0.812, p |
