Impact of the use of cryobank samples in a selected cattle breed: a simulation study

Table 1 Description of simulation scenarios

Scenarios		Use of cryobank bulls in generation 9		Selection scheme during stage 2 (generations 9-12)
Objective	Code	Selection of cryobank bulls	% of male offspring	Selection criterion	Use of sire of bulls
Improving trait B	b1	Higher TMI value	40	EBVA	No change
	b2	Not used	0	TMI	No change
	b3	Higher TMI value	40	TMI	No change
Maintaining genetic diversity	d1	Minimizing kinship with current population	40	EBVA	No change
	d2	Not used	0	EBVA	Conservation of male lines
	d3	Minimizing kinship with current population	40	EBVA	Conservation of male lines

EBVA: estimated breeding value for trait A; EBVB: estimated breeding value for trait B; TMI: total merit index computed as the weighted sum of EBVA and EBVB
