Artificial insemination of pigs-- collection of boar semen

Boars for semen collection should be excellent boars at the age of 7 months and weighing between 110 and 120 kg. First of all, prepare a sperm collection place to prevent stagnant water from slipping. Secondly, the boar for semen collection must first carry out semen collection training to make it adapt to the semen collection of pseudo-Taiwan pigs. It is necessary to clean up the abdomen and foreskin of the boar in advance, remove dirt and cut off the foreskin. Third, prepare a fake pig and collect semen cup (preheat and keep 37 degrees before collecting semen, fix the sterilized gauze at the mouth of the cup, and concave slightly). The fourth boar generally collects semen once every 7 days, increases to 2 times a week after 12 months of age, and 2 to 3 times a week after adulthood.
