  2. Semen collection
  3. Semen evaluation
  4. Semen processing
  5. Semen storage
  6. Heat detection
  7. Deposition of semen

Assessment of male Animal

It is important that performance records of males (stud) should be well kept to known the past performance

  2. Quality of semen: The volume must be compared with established standard bearing in mind the age, season and the breed of the animal.
