1

What is normal gestation of a cow is ?

280-285 days

2

What do cotyledonary attachments attach?

Between placental cotyledons and uterine caruncles

3

At what point are placentomes palpable? 

3 months gestation

4

What is the key source of progesterone?

CL until 120-150 days

Adrenals and placenta beyond 150 days

5

How do you terminate a pregnancy before day 150? after?

Before 150: prostaglandin

After 150: corticosteroids and PG

6

What are the possible consequences of fetal death in utero?

  • Abortion with no associated problems
  • Fetal mummification
  • Fetal maceration
  • Pyometra

7

Describe the aetiology of fetal mummification?

Fetal death, CL maintained and cervix remains closed

Fetal fluids are gradually resorbed and fetus preserved in a mummified state

8

How do you treat a mummified fetus?

Try prostaglandin injection

May need manual assistance

Luteolysis may occur but failure of expulsion

9

What happens during fetal maceration?

Fetal death > cervix partially dilates > decomposition proceeds

10

How to deal with fetal maceration?

Best to cull

11

What ist he cause of pre-partum metritis/emphysema?

Due to dystocia or abortion agent causing fetal death

12

How do you treat pre-partum metritis/emphysema?

Remove her vaginum

13

What is the cause of hydramnios?

Associated with fetal abnormality

14

What is the cause of hydrallantois?

Associated with placental abnormalities

15

When does hydrallantois occur?

Last 2 months of gestation

16

How do you treat hydrallantois?

May go to term with no problems

May need to be induced (dexamethasone/PG)

Assistance may be required due to uterine inertia

May require surgery (if cow becomes recumbent or anorexic) - drainage of fluid and removal of foetus by caesarian

17

What is the cause of hydrocephalus?

Abnormal CSF ciruclation

18

What is fetal anasarca?

Grossly swollen foetus due to subQ fluids 

19

How do you treat fetal ascites?

Will cause dystocia - may require embryotomy or caesarian

20

How do you treat a prolapsed cervix/vagina?

Need to replace and retain until calving

Use epidural anaesthetic and Buhner suture
