Farrowing Piglets
|
In normal farrowings total born made up from live, dead and mummified piglets |
|

Live piglets |
Stillborn
piglets |

|
Mummified
piglets |
But if a piglet
is not born within 30 minutes manual assistance may be required. |
|
Consider oxytocin
5 iu/im first and wait 15 minutes. If still no piglet- investigate |
|
|
Dystocia in the pig may be associated with uterine inertia,
obstruction in the birth canal, simultaneous presentation of two fetuses,
abnormality of the pelvis, oversized foetus (>2
kg). Calcium deficiency is rare. Uterine inertia more commonly associated
with unfit sows. Note outdoor sows
very rarely require manual assistance, whereas some stockpeople feel it
necessary to assist 80% of indoor sows to reduce stillbirths |

|
Normal presentations |
|
|
|
|
|
The piglet may
present head or rear first and be born normally. Little effort is should be required to
remove either of these presentations. |
|
|
Presentations that may require assistance |
|
|
|
|
|
Occasionally the hind legs will be forward and the forelegs back. Assess the situation and by manipulation bring the forelegs forward and if possible move the rear legs backwards. Place a head rope and leg ropes and farrow the piglet |
This unusual presentation can often be farrowed without complication. If possible rotate the piglet, pressing on the eye of a live piglet will generally make it turn. |
|
|
|
|
This presentation is not uncommon. Push the forward piglet backwards and realign the forward piglet and farrow. |
Abnormalities may present a difficult challenge – Siamese for example. |
|
|
Be very careful about pulling on the lower jaw of the piglet, as fracture of the jaw is likely. If the piglet is overlarge or difficult to remove, a head rope applied around positioned behind the ears and into the mouth, together with two leg ropes will greatly assist the piglet to be farrowed. |
|
Do not over try. If there is no piglet present within the vagina it is better to administer oxytocin 5 iu/im and wait 15 minutes and examine again. |
|
|
Once a piglet is born, its care is only
just beginning |
|
|
|
|
|
Ensure it can breath easily |
Weak piglets may need help to get colostrum |
|
End of farrowing |
|
|
|
|
|
The presentation of a mass of placenta indicates the end of parturition. Normally within 4 hours of the last piglet. |
