ABSTRACT
Sixty male broiler breeders (ISA-MPK breed) 50 at their final reproductive life (68 week-old), and 10 at the pick of production (35 week-old), from six different flocks (10 males/flock) were used to evaluate the effect of age on the motility, vigor and mass motility under normal management field conditions. A non-parametric test was applied and no differences were observed between ages for the analyzed traits. The regression analysis showed a significant effect of testicle weight on semen quality only for birds at 35weeks of age.
