The aim of the study was to investigate the influence of feed components containing omega-fatty acids on the boars’ testosterone (T) and oesteradiol-17 beta (E) concentration of blood in the sexual hormone activity reduced period (April-June) and the influence of one hour transportation on the boars' sexual hormones concentration of blood. The experiment was performed with 10 boars in the company of artificial insemination. In the identical dates of 2010 and 2011 serum samples were analyzed for: T, E, total cholesterol, HDLH and LDLH and quality of boars' ejaculate. There were positive effect of omega fatty acids on boars' serum T, E and HDLH concentration and negative influence on the total cholesterol and LDLH levels. One hour quiet transportation promotes for a short period a significant (p is less than 0.05) elevation of serum T and E for pen kept boars'.
