font face="Times New Roman" size="1"> Two-day-old broiler chicks of both sexes were selected on the basis of their escape performance from a T-maze apparatus. and termed high performance (H-P). moderate performance (M-P), and low performance (L-P) chicks. Then, the three groups were reared to reach 15 days of age and the gender and body weights measured. A lineal regression analysis showed a significant positive correlation between body weight and the performance of chicks, without sex discrimination. Furthermore. two-way ANOVA on the body weight (selection X gender). showed a significant main effect of selection. LSD pairwise comparison of means shows that th
