Application of ethologic techniques in commercial swine production made it possible to take into account the specific features of pigs, to separate animals suitable and unsuitable for animal husbandry in the conditions of industrial production technology, as well as to solve many other problems connected with management, animal behaviour at farms and complexes, that could make it possible to obtain additional production without investing additional material resources. The behavioural trait of emotional stress resistance rendered the authentic positive impact on growth rate of piglets during the suckling period. Taking into consideration, that emotional stress resistance, as well as the temperament as a whole, remained invariable as long as life endures, it could be possible to recommended to use the analysed trait for the selection of young stock for self- replacement in the conditions of pig-breeding complexes, and for the selection of the most fast-growing animals with the simultaneous steady resistance to the emotional stress. In the process of replacement pigs selection it was inefficient to take into consideration only their live weight. Considering that the live weight of some piglets which were non-resistant to emotional stress, but with heavy litter, was high enough, however, as their temperament did not vary as long as life endures and emotional instability will necessarily manifest itself in the subsequent parent qualities of the future sows
