Use of the coefficients of heritability, correlation and regression when selected of pigs of large white breed
In article are studied of heritability, correlation and regression reproductive qualities herds of pigs of large white breed in LLC «Zurinsky Agrocomplex». It is established that a herd of pigs is charactirised homogeneity on reproducnive qualities about than evidenced by the coefficients of heritability (h² = 0,002-0,27). It is revealed that between reproductive signs there are positive and reliable communication. The most high coefficients regression are obtained between prolificacy and weight of the nest at weaning (R = 6,61) and the number of piglets and weight of the nest at the age of 2 months (R = 9,55).
