Table 5 Predicted genetic gain using selection index

Estimate	Multi-trait selection			Single trait
	Susceptibility	Infectivity	Mortality	Mortality
Genetic gain in trait unit (days)	0.860	0.903	0.488	0.597
Genetic gain expressed as percent of the population mean	9.8	10.3	5.5	6.8
Variance of the index	0.458			0.059
Variance of the breeding goal	1.341			0.333
Accuracy of index	0.585			0.422
