Abstract
Blood lipid peroxides (TBARS) and naturally present blood antioxidants glutathione (GSH), haemoglobin (Hb) and plasma albumin (ALB) were determined in nine Simmental young bulls. Blood samples were taken five times. The animals were intensively fattened. Mean TBARS content showed a biphasic pattern in the course of growth with the highest value at 11.7 months of age. GSH content increased until the age of 8 months when the highest concentration was determined. Albumin and Hb concentrations were highest at 15.2 months of age. The main contributor to the significant increase and decrease of TBARS values could be the development of skeletal muscle tissue. Correlations among the parameters investigated were not significant in the course of growth, with the exception 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 the indicators of oxidant stress in young bulls were within the physiological range and that, possibly, blood natural antioxidants complemented each other.
