Selection of Maternal lineage of parent form cross “Smena 8”

Abstract

It has been established that the body weight at the age of 35 days is increased of 8,2...9,0 % as a result of blood transfusion from the new genetic material, results-oriented selection work, as well as the genotypes evaluation and selection with higher genetic potential of growth rate at the first week of growing bird. Increasing the chickens rate of growth and realizing direct selection on feed conversion within 5 years improved this characteristic in maternal lineage B9 by 4,9...5,2 %; and musculation - 2,3...3,6 %, leg - 1,5...5,0 %, chickens incubation - 1,5 fertilized eggs - by 1,4 %. hatching rate of laying bird - by 2,5 %. The bird of new maternal lineage female parent has a high genetic potential and can be used in broiler production.
