Abstract

II Características quantitativas em matrizes de codorna de corte através de análises multicaracterística Quantitative traits in meat-type quail through two-trait analysisRecebido para publicação 13.02. (P0, P7, P14, P21, P28, P35, P42, P77, P112 and P147), average egg weight (POM1, POM2, and POM3 POM4), average weight of the shell ( PCM1, pcm2, and PCM3 PCM4), average weight of yolk (PGM1, PGM2, and PGM3 PGM4), weight of albumen (PAM1, PAM2, and PAM3 PAM4), average egg specific gravity (DM1, DM2, DM3 and DM4 ), average width of the egg (LOM1, LOM2, and LOM3 LOM4), average length of egg (COM1, COM2, COM3 and COM4), eggs (N1, N2, N3 and N4), total egg production (TXT) and age at first egg (IDPO). For the group of genetic UFV1, an increase in weight of birds may result in an early and that IDPO to select for increased body weight of birds does not result in significant losses in egg quality. As for UFV2, a selection made at 35 days can identify the most weight matrices throughout the production cycle, and do not generate large losses in total egg production.
