metritis
therapeutic abortion or induction

25
Q

what induces ovulation?

A

cervical stimulation
ovulation-inducing factor

26
Q

when does ovulation occur?

A

24-30 hours post copulation

27
Q

can be >365 days

29

<6 hours

30

33
Q

when should you rebreed postpartum?

A

14-21 days
can ovulate 2-3 weeks postpartum with good conception rates (worse if <14 days and >3o days)

34
Q

not camelids
cattle, sheep, goats
