Performance and Prediction and Clustering Analyses of Characteristics of Parental Broiler Lines of Production Traits
DOI: 10.1590/S1516-35982002000300011
This study was conducted using data from single crosses (partial diallel) of male lines, group I (LL, TL, ZL, TT, LT, ZT, ZZ, LZ, TL), female lines, group II (PP, KP, VP, KK, PK, VK, VV, PV, KV), besides two control lines (LLc and PPc). A completely randomized block design, with three replicales, 82 single crosses treatments with nine females for experimental unit was used in the analyses. The production traits analyzed, eleven total, were: fertility at 32nd, 38th, 42nd and 49th weeks of age, hatchability at 32nd, body weight at day of age, body weight and feed:gain ratio at 42nd days of age, and carcass yield, breast yield and fast pad yield at 42nd day of age. The averages and prediction of the hybrid ones showed to be important source of information. Similarity exists among the crossings originating from of the use of the line 1, as progenitor.
