Opis:
The investigations were carried out to compare selection conducted on the basis of progeny with that on the basis of animals'own performance. Selection was conducted for the body weight at weaning (at the age of 21 days), which is a trait of low heritability (h²=0.1). It was run throughout 15 generations, whereas in generations 13 and 14 three experimental replicas were crossed to obtain population free of inbreeding. A cumulated response to selection was higher in the group selected on the basis of animals' own performance, but after crossing the replicas it decreased clearly in the both groups. The cumulated selection differential was higher in the group selected on the basis of animals' own performance. However, a statistical analysis of the obtained results showed no significant difference between the two selection methods.

Opis:
A comparison was made of a correlated response to selection between populations of mice selected for body weight at weaning on the basis of their own performance or their progeny. Selection was conducted throughout 15 generations and during the last two generations, three replicas were crossed within each group. A correlated response to selection of the body weight on day 42, weight gains between day 21 and 42 and litter size at birth was significantly higher in the group of mice evaluated on the basis of their progeny. A negative correlated response occurred in the litter size at birth in the group evaluated on the basis of animals' own performance. The realized genetic correlations in the group evaluated on the basis of animals' own performance was 0.9, 0.1 and 0.8, respectively, between the body weight on day 21 and 42, body weight on day 21 and weight gains between day 21 and 42, body weight on day 21 and litter size at birth.
