Q

Advantages of early pregnancy detection

A
  1. It makes possible to cull or re-breed non pregnant, feed wasting females
  2. Allows closer grouping of a number of sows for a farrowing period
  3. It gives early warning for breeding troubles such as infantile boars or cystic ovaries
  4. enables the producer to make more effective use of his breeding facilities & to plan more adequately for farrowing, nursing & finishing

Q

Interval between piglets not be longer than

A

37
Q

farrowing hours

A

30 mins to 6 hours

38
Q

Assistance to sows should be given if the following is observed:

A

a. Restlessness
b. Excessive straining
c. Piglet interval is 45 minutes

39
Q

Farrowing problems are usually observed in

A

older, overweight & nervous sows

40
Q

Reasons why piglets are slow to be born

A
  1. Large piglet is stuck in the birth canal
  2. Piglets coming out at the same time
  3. Exhausted sow for farrowing quite sometimes
  4. Farrowing house is to warm
41
Q

Procedure for assistance in farrowing

A

a. Wash the sow’s vulva & its surrounding to remove organic matter & dirt
b. Wash hands & lubricate
c. Insert hand slowly into the vagina, then to the cervix. The uterus will be either straight ahead or down over the brim of the pelvis
d. When your hand is in the uterus, you can palpate the piglets head or hind legs, then pull it out. If 2 piglets are stuck, push one back &synchronize the pulling with the contraction of the sow. Avoid tearing the vagina, cervix & uterus to avoid problems with metritis.
e. In case you cannot palpate a piglet, that’s the only time OXYTOCIN is used

42
Q

accounts for 5 to 7% of all piglets born or 1 piglet for every 2 litters

A

Stillbirths

43
Q

used to detect piglets that died from stillbirth

A

lung floatation method

44
Q

Causes for stillbirths

A

a. Increased farrowing time
b. Warm farrowing room
c. Piglets born towards the end of farrowing

45
Q

drug to induce farrowing

A

prostaglandin

46
Q

One of the most abrupt &major changes for many animals

47
Q
