Abstract
The purpose. To probe influence of boars of large white breed of foreign selection upon indexes of exterior, dressing and meat qualities of their progeny, to calculate the level of correlation between attributes and to determine efficiency of use of indexes of constitution of a body for early prediction of quantitative attributes with high level of inheritance. Methods. Biometric, analytical, and conventional zootechnical methods. Results. It is fixed that use of boars of large white breed of foreign selection positively influences indexes of linear body growth of their progeny in an early ontogenesis, and also dressing and meat qualities. Conclusions. The maximum indexes of body build (prolixity, massiveness, bony) are characteristic for the young stock of pigs gained from sows of large white breed of Ukrainian selection and boars of large white breed of French selection (+1,47 %). Use of boars of large white breed of foreign selection promoted increase of dressing percentage for 2,93%, increase of length of the refrigerated carcass for 2,4 cm, increase of square of “muscle eye” for 3,06 cm2, increase of mass of rear third part of refrigerated half carcass for 6,37%. With the purpose to early predict dressing and meat qualities of young stock of pigs it suggested to use indexes of body constitution: deep-chestness (r=0,443 – 0,496), bony index (r=0,419).


Key words: young stock of pigs, exterior, meat qualities, indexes of constitution of a body.
