Velychanska S. Improvement of pigs selection techniques taking into account the level of sex dimorphism.

Will Aim work there was improvement of acceptance an fenotype of estimation a pig on base of determination of level of sex dimorphism young male pigs in 2-month age and determination of its relationship with intensity of growing, fattening properties and meat qualities of bestial different direction of efficiency. Methods of animal technics research modeling of selective features and determining biochemical indices of blood serum were used. It Is Stated that high fattening properties of quality had the young male from class a plus-variant (M+) for level of manifestation of sex dimorphism. This has provided the gain of product in calculation on 100 goals live-stocks 1444,0 g.. and 1395,37 g. Expediency of using T.Bridges' model for evaluation of growth parameters of pigs and forecasting of animals' weight are shown. Results of research are implemented at industrial agri complex Agrifarm Separate Enterprise 'Zaporizka Nuclear Power Station'.
