Postpartum dysgalactia syndrome in sows: effects on behavior of sows and piglets

Table 3 Nesting behavior and bar biting in sows suffering from postpartum dysgalactia (PDS+) and healthy sows (PDS−) during the periparturient period. Results are given as a % of all observations

Sow activity	Relative to parturition	Group	Activity performed	p-values	p-values for the total period
Sow activity	Relative to parturition	Group	(% of obs.)	(group*)	(group)	(time)
Nesting	Before	PDS+	31
	Before	PDS−	32	0.56
	During	PDS+	7
	During	PDS−	9	0.04
	After	PDS+	6
	After	PDS−	8	0.0004		< 0.0001
Bar biting	Before	PDS+	23
	Before	PDS−	23
	During	PDS+	3
	During	PDS−	3
	After	PDS+	2
	After	PDS−	2		0.70	< 0.0001

*Due to the interaction between time period and group, nesting was estimated separately for the time periods before, during and after parturition
