===Hypocalcemia (Eclampsia)===
Pregnant sows can develop an acute calcium deficiency due to the metabolic demands of parturition combined with lactation. Obesity and stress are key predisposing factors.
<br />
Pathologic findings will include fatty liver and kidneys and in general are similar to the macroscopic findings of pregnancy toxaemia but usually more severe. At the point of onset of clinical signs the prognosis is poor.

===Miscarriage and Abortion===
===Miscarriage and Abortion===
If abortion occurs early in gestation (up to 40 days) the sow will commonly not be systemically affected. Later than 40 days will result in systemic illness with severe blood loss with potentially fatal consequences. <br />

This type of infection is usually caused when a foreign body such as saw dust becomes trapped in the prepuce causing preputial dermatitis. This can lead to a swelling of the prepuce but also cause inability to copulate. Similarly it has been found that saw dust can also block the vagina of the female also leading to an inability to achieve copulation. <br />

To decrease the risk of preputial infections and vaginal blockage wood shavings are superior to saw dust.<br />
