The performance of two broiler breeder lines, developed by Federal University of Viçosa – UFV (M1 and F1) was tested against two mainly trade mark lines (C1 and C2), using methods of multivariate analysis for the evaluation of the genetic divergence. Four important economic traits were evaluated: age at sexual maturity (IMS), egg number (NO), average egg weight (PO) and body weight (PM), during three periods of the productive life of the birds: initial (25th to 32nd week of age), […]
