Abstract
A method for assessing and selecting sows by stress susceptibility of descendants includes assessing thereof by reproductive qualities and their own productivity of descendants. The corresponding class of breeding value, according to which selection of animals is carried out, is determined. An assessment of the sows is carried out in two stages: according to the first stage individual stress susceptibility of piglets in a nest of each sow and according to the coefficient of changing live weight is determined, and according to the second stage percentage of descendants with different stress resistance in their nests is determined. For breeding according to the given character sows are selected, in the nest of which 80-100 % stress-resistant descendants is counted.
