The document discusses several methods for collecting semen from animals, including using a breeding bag, artificial vagina, message method through the rectum, and electroejaculator. The artificial vagina is considered the best method as it is easy to use but requires training the male and cleaning parts to avoid contamination. Other methods risk contaminating the semen sample or harming the animal.
