Mathematical models for determining equating nests sows and their zootechnical evaluation
Abstract
The results of studies of indicators of reproductive ability of sows of large white breed provided the use of pure breeding and industrial crossbreeding swine-producing genotype ½ duroc × ½ pietrain, developed a new mathematical model of evaluation index determining equating nests (IEN) sows on live weight of piglets at the date of their birth, and is also designed IEN provided various variability of multiple pregnancy and a large sows, as well as live weight of pigs.
The number of significant correlations signs of reproductive ability of sows and estimated indices of equating nests ranges from 50,0 to 91,7 percent.
