It is interesting to induce the sows together for farrowing by using
prostaglandines only if you are present during farrowing. Priority has to be put on
piglets because they have to drink colostrum as soon as their first 4 hours.
A normal farrowing lasts about 2 1/2 hours. When searching in the sow, use a
disposable glove covered with iodine gel (Vaginet).
The room temperature should be around 20°C. However, piglets arrive from inside
the sows which was 37°C to 38°C temperature. Therefore, with a infra red
thermometer adjust comfort zone to approximately 32°C.
The "splay legs" are lowered by using a washable farrowing mat or a disposable
farrowing mat. "Splay leg" piglets are taped with masking tape, then placed in a
plastic box one foot high by 18 inches long beneath a lamp to obtain a temperature
of about 32°C.
Since they have not drank, intube them (porcisonde) with some maternal milk
(approximately 10cc). The same technique is used with smaller or poor piglets. As
soon as a piglet bleeds from it's belly button, use a clip to stop bleeding. Born
dead are lowered by intervening when the last piglet is dry or when the last one
has arrived 20 to 30 minutes after.
Evaluate the risks by knowing if the sows had still born the last time she
farrowed. Adoption is only made in the first 48 hours. By the mid afternoon, it's
adoption time. Small ones together under a gentle gilt (approx. 12 piglets), then
bigger ones together under a mother with not so good nipplles (approx. 10 piglets)
then other sows will get 10 or 11 piglets.
The day after farrowing, observe the sows temperature (more than 39,5°C) and the
sows that have infections so you can intervene with the right medications at the
right time.
