How do we remove piglets from the uterus in sow?

a. I always fix the head of the piglet and take it out through the uterine wound
b. With one hand I fix the head, or the hindlegs, while with the other hand I apply a
massage to the outside of the uterus
c. I inject oxytocin and wait until the piglets appear in the wound after each other, then
I gently take them out
d. I open the uterus above every piglet then close the wound immediately after
removing each piglet

b. With one hand I fix the head, or the hindlegs, while with the other hand I apply a

3

Where do I open the abdominal wall in the swine for c-section?

a. Exclusively on the left paralumbar area
b. Only ventral midline
c. Even on the right side, along the direction of the internal oblique muscle
d. Near the vulva in a dorsolateral direction

c. Even on the right side, along the direction of the internal oblique muscle

4

Which statement is correct?

a. C-section is the only obstetrical aid in sows
b. This should always be applied in double sided hip flexion
c. I always have to choose this if parturition stopped because a piglet had obturated
the birth canal, and I can not remove it per vaginal
d. If I cannot perform an episiotomy

c. I always have to choose this if parturition stopped because a piglet had obturated
the birth canal, and I can not remove it per vaginal

5

When do I not necessarily need to perform a c-section in a sow?

a. During uterine torsion
b. Usually it can be applied in presentation failures, but it’s not often indicated since
often these can be solved in another ways as well
c. If fetuses have died
d. If piglets do not born after the administration of oxytocin

b. usuaally it can be applied in presentation failures, but it's not often indicated since often these can be solved in other ways as well

12

What is the relation between the heat and ovulation in the swine?

a. - Duration of the heat is 24-36 h, ovulation at the beginning of estrus
b. - Duration of the heat is 3 days, ovulation between 46-54 h
c. - Duration of the heat is 24 h, ovulation 12 h after the end of clinical oestrus
d. - Duration of the heat is 5-7 days, ovulation 24 h before the end of clinical oestrus
e. - Duration of the heat is 9 days, ovulation between day 2-4

b. - Duration of the heat is 3 days, ovulation between 46-54 h

13

Oestrus cycle of the gilts can be synchronized by:

a. - Single luteolytic dose of prostaglandin F2a (or analogue)
b. - Two luteolytic injections of prostaglandin F2a (or analogue) 11 days apart
c. - Long term use of progesterone releasing intravaginal device (PRID) or subcutaneous
implant
d. - Feeding synthetic progestagen (e.g. Regumate) for 10-15 days
e. - GnRH – PGF2a – GnRH treatment (Ovsynch method)

d. - Feeding synthetic progestagen (e.g. Regumate) for 10-15 days

14

For maintaining the porcine pregnancy luteal progesterone is required:

a. - During the first 35-40 days, thereafter the foetoplacental unit is enough
b. - Throughout the entire pregnancy, because the swine is CL dependent species
c. - For approx. 100 days, later stage of the pregnancy is maintained even after
ovariectomy
d. - Second half of the pregnancy can be maintained by corticosteroid hormones alone
e. - The porcine pregnancy is maintained by oestrogen hormones

b. Throughout the entire pregnancy, because the swine is CL dependent species

15

What is typical for c-section in swine?

a. - It is performed in standing position
b. - The pregnant uterine horn has to be opened near the tip of the horn
c. - The uterus should preferably be opened intra abdominally

d. - Usually it is performed in anaesthetized animals

16

What do we do with the placentas during c-section in the sow before closing the uterine wound?

a. - We remove all of them
b. - We cut those parts that hang out of the wound and leave the rest in the uterus
and we put uterine pills containing antibiotics into the lumen
c. - We detach the easily detachable cotyledons from the caruncles
d. - We remove them and flush the uterus with saline solution

b. - We cut those parts that hang out of the wound and leave the rest in the uterus
and we put uterine pills containing antibiotics into the lumen

17
