    older goats
  7. Inguinal hernias are common or uncommon in pigs? and how do we check for them?

    • 1. large inguinal rings
    • 2. owner has seen herniation in this patient before
    • 3. congenital hernia that already corrected with time
  17. what can you do in a castration to help prevent herniation?
    close external inguinal ring
  18. Is peritonitis a common complication of castration? what are 2 other very rare complications?
    • no- very rare
