Effects of gender and gonadectomy on some biochemical serum parameters in swedish landrace pigs

Serum biochemical parameters are used to evaluate animal condition and detect diseases. The gender-related differences in physiological processes, pathophysiology, diagnosis and treatment of diseases have an increasing importance in human medicine, and these differences should be investigated and implemented in animal models. Therefore, the aim of this study was to investigate the effects of gender and gonadectomy in pigs on some blood serum biochemical parameters. The study was conducted on 20 clinically healthy, sexually mature pigs of the Swedish Landrace breed. The pigs were divided into four groups (n = 5 each): intact boars (age 271 ± 4 days), intact gilts (age 270 ± 4 days), castrated boars (age 267 ± 5 days) and castrated gilts (age 269 ± 4 days). Blood samples were taken from the jugular vein by using blood test tubes without anticoagulant. After centrifugation, the serum was separated, and the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyl transferase (GGT) as well as the concentrations of urea and glucose were determined spectrophotometrically. Data analysis was performed by using the Statistica v. 13.4 software. The normality of dana distribution was tested by using the Kolmogorov-Smirnov test, and the significance of the differences between the groups by using an analysis of variance and the Tukey HSD test. The study results showed that the castrated boars had a significantly higher (p < 0.05) urea concentration in the blood serum than the intact boars. In addition, the castrated boars had a significantly lower (p < 0.05) serum glucose concentration than the intact boars and gilts. The serum activities of AST, ALT and GGT were the highest in the castrated boars, and the lowest in the intact boars, except for the GGT activity, which was the lowest in the castrated gilts. It can be concluded that for the interpretation of serum biochemical parameters in pigs, i.e. to ensure an accurate clinical diagnosis and prognosis, gender and gonadectomy should be considered. However, further studies including a higher number of animals are required in order to define the effects of gender and gonadectomy on the values of biochemical parameters in blood serum of pigs more precisely.
