The objetive of this study was to evaluate the performance of broiler genotypes using repeated measurements. Four genotypes (A, B, C, and D) and two sexes were evaluated at six ages (7, 14, 21, 28, 35, and 42 days) for average feed intake (AFI), average body weight (ABW) and feed:gain ratio (F/G) using an unbalanced incomplete blocks 4×2 factorial design. Five error co(variance) structures were tested using the MIXED procedure of SAS® for statistical analyses. Averages were estimated by least […]
