Sexual behavior of castrated boars treated with prostaglandin F2α
چکیده انگلیسی

The objectives were to test the hypothesis that exogenous prostaglandin F2α (PGF2α) temporarily restores sexual behavior of castrated boars, and to evaluate effects of PGF2α on serum hormone concentrations. At 35 d after castration, nine lean-type adult boars were randomly assigned to three treatments in a 3 × 3 latin square (with three replicates). Treatments were three doses of PGF2α doses (0, 10, and 20 mg) and three periods of treatment, with 5 d between each period. Serum testosterone (T) concentrations were non-detectable at the start of the experiment. Serum concentrations of estradiol (E2), LH, prolactin (PRL), and cortisol were unaffected (P > 0.05) by PGF2α treatment. The interval from treatment to ejaculation in boars treated with 10 mg (758 s) or 20 mg (660 s) PGF2α did not differ, but were different (P < 0.05) from control boars (>1 800 s). Ejaculation duration and false mounts differed (P < 0.05) between control boars and boars treated with 10 or 20 mg PGF2α. In conclusion, PGF2α treatment did not change serum concentrations of T, E2, LH, PRL, or cortisol, but restored sexual behavior. This restoration may have been due to an effect of PGF2α directly in specific areas of the brain, or indirectly via release of other hormones that stimulated areas in the brain that affected sexual behavior.
