Describe how Deslorelin works for chemical castration and in which spp. is it typically used?

Why should castration of camelids be delayed until after puberty?
have an increased risk of physeal fractures if done too early

Most common side for acquired, indirect inguinal hernias to occur on (cattle)
In cattle, acquired direct hernias are assoc. with? And why is it a surgical emergency?
risk for incarcerated bowel is very high
Because congenital inguinal hernias are heritable, repair is accompanied by?
Describe the difference between direct and indirect hernias in DOGS
