Prostaglandin () can facilitate release of epinephrine from the adrenal gland. The objective was to extend these findings and determine the effects of on sexual activity and semen collection training in sexually inexperienced boars. Boars (n=32; days of age) were moved individually once weekly to a semen collection room equipped with an artificial sow. Before entering the semen collection room, boar received i.m. treatments of at doses of 5 (n=8), 10 (n=8), or 20 (n=8), and control boar (n=8) were not treated. Reaction time (elapsed time after entering collection pen until the start of mounting) for boars receiving 5mg (), 10mg () was shorter (p<0.05) than for controls (). Duration of ejaculation (min) per session was longer (p<0.05) for (10 mg, 20 mg)-treated boars (, ), compared to control (). The number of training session per boars was less (p=0.056) for 10mg-treated boars (), compared to control (). Semen characteristic such as volume, concentration, the number of total ejaculated sperm, were similar for -treated and controls. There was no apparent difference on sperm movement characteristics (Mot: motility, VCL : curve linear velocity, VSL : straight line velocity, VAP : average path velocity, LIN : linearity) after semen preservation by collected with or without treatment. In summary, administration of in boars increased the sexual activity and facilitated the training boars to mount an artificial sow for semen collection, but did not affect semen characteristic.
