Flashcards

Sexual Maturity

The stage when an animal is fully developed physically and reproductively ready to mate.

Premature Breeding

Breeding before an animal reaches full physical development, leading to potential complications.

Dystocia (Premature Breeding)

Complications during birth due to a young animal's pelvis not being fully developed.

Delayed Breeding

Breeding after a long period of time, potentially leading to complications due to the pelvis becoming hardened.
