The purpose of the work is to investigate the life expectancy and reproductive qualities of sows of various intrabreed differentiation according to the "level of adaptation" index, as well as to determine the criteria for the selection of highly productive animals according to this integrated indicator. It was established that the number of sows from which 100 or more live piglets were obtained during the breeding period is 42 heads or 27.45%. Taking into account the intrabreed differentiation of animals according to the "level of adaptation" index, a reliable difference was established in terms of life expectancy, duration of breeding use, number of farrowings obtained, number of live piglets obtained, multifertility, nest weight at the time of weaning at the age of 28 days, index of M.D. Berezovsky. The number of reliable correlations of different strength and direction between indicators of long-term adaptation and signs of reproductive qualities is 78.57 %. The criterion for selecting highly productive sows according to the "adaptation level" index is a variation of this integrated indicator at the level of 3.22-7.32 points. |
