The devil’s dilemma: sow or piglet?

September 28, 2016

Go back

We did the math. When is it no longer profitable to increase piglets weaned per sow per year? The answer is «far above 40» and the main reason is the recovery of feed used by the sow. The dilemma is that increasing litter size in the same size uterus causes crowding.

Placentas have to become smaller and the piglets therefore lighter. We try to overcome this by producing more vigorous piglets. The alternative would be a larger sow with a larger placenta, but that would lead to higher sow maintenance requirements and the need for even larger litters to cover the costs.
