Sažetak
Blood lipid peroxides (TBARS) and blood antioxidants glutathione (GSH), haemoglobin (Hb) and plasma albumin were determined in nine Simmental young bulls. Blood samples were taken five times at 3.2, 5.4, 8.0, 11.7 and 15.2 months of age. The animals received concentrate, roughage and water ad libitum. Mean TBARS concentration showed a biphasic pattern in the course of growth with the highest value at 11.7 months of age. GSH content increased till the age of 8 months when the highest concentration was determined. Albumin and Hb concentrations were highest at 15.2 months of age. We assume that the main contributor to the significant increase and decrease of TBARS values could be the development of skeletal muscle tissue. Correlations among investigated parameters were not significant in the course of growth with the exceptions of GSH vice Hb at 5.4 months of age and TBARS vice Hb and TBARS vice ALB at 15.2 months of age. It might be concluded that oxidant stress in young bulls was within physiological range and that blood natural antioxidants complement each other.
