| Training must start between 5 and 6 months of age, every day during 10 to 15 minutes morning and evening with a mobile dummy into its pen. This must be impregnate with urine from a sow in heat or semen from other boar. The technician should be always the same person. The dummy must be moved as a sow in heat, stopping it when the boar hit it with the nose, mimicking the standing reflex of a sow in heat. If it is necessary, a sow in heat can be used. The semen collection must be performed without hurry, allowing that the ejaculation process finishes, which can last from 5 to 20 minutes. During all this period the pressure of the hand on the penis must be maintained. It is necessary to take into account the sigmoid shape of the penis, which is unpacked in the outside. This makes necessary to accompany the movement of the penis and never force it. |

| Usually, a boar with a good libido will start to be collected on the dummy in one week. After 3 or 4 semen collections in its pen with the mobile dummy, we can change to the semen collection pen with a fixed dummy. Since this moment, semen collection will be performed at a rate of one per week, and progressively to three times every two weeks being the boar 1 year old. The mobile dummy must have a base with a pyramidal shape in order to avoid accidents at the time of collection. The semen collection pen must be a quiet room without distractions for the boar. The floor should be not slipping and easy to clean and disinfect. |
