Sažetak
Sex-related differences in physiological processes, pathophysiology, diagnosis and treatment of disease have great importance in human medicine, and these differences should also be investigated and implemented in studies on animals. To our knowledge, this study is the first to investigate the effects of sex and castration on the serum biochemical profile of commercial pigs. The study was conducted on clinically healthy, sexually mature fattening pigs of the Swedish Landrace breed, divided into four groups: intact males (n = 6), intact females (n = 5), castrated males (n = 6) and castrated females (n = 7). Blood samples were taken from the jugular vein using blood test tubes without an anticoagulant. After centrifugation, the serum was separated, and the values of the following parameters were determined by spectrophotometry: the activities of aspartate aminotransferase, alanine aminotransferase and γ-glutamyl transferase, and the concentrations of total proteins, albumins, triacylglycerols, total cholesterol, glucose, urea, bilirubin and creatinine. The study results showed significantly lower (P<0.05) serum glucose concentrations in castrated males as compared to intact males. However, castrated males had significantly higher (P<0.05) urea concentration than intact ones. There were no significant between-group differences in the values of the other parameters investigated, however, certain patterns of occurrence were observed. Accordingly, further studies are required in order to define more accurately the effects of sex and castration on the values of biochemical parameters in the blood serum of pigs.
