Relationship between piglets’ survivability and farrowing kinetics in hyper-prolific sows

Table 8 Multivariable model of piglet’s birth weight and cumulative birth interval on piglet mortality 24h after birth

Variable	Piglet mortality 24h after birth				Adjusted R²
	Estimate	SEM	Confidence interval
	Estimate	SEM	Lower limit	Upper limit
Intercept	−0.85	0.63	−2.11	0.36	0.32
Piglet’s birth weight (kg)	−2.64	0.57	−3.80	−1.55
Cumulative birth interval (min)	0.003	0.001	0.001	0.004

This analysis was performed with 983 piglets born from 58 sows. Stillborn and mummified piglets were not included
Sow was considered as a random variable in this statistical model
