In a sample of 253 individuals born from 5 females and 10 males estimates of heritabilities and genetics, phenotypics and environmental correlactions were determined among the following traits: body weight, body length, body height and head length at the age of 60 days. Estimates of heritabilities calculated with components of variance for sire showed values for body weight of 0,21 ± 0,14 and for height between 0,24 ± 0, 78. It also showed values to the body height for 0,04+0, 7 O and for head length of 0,08 ±O,12. The genetic correlations values among the traits showed a high association among them. Due to the heritabilities values, the individual selection may be used for body weight and body heigth.
