Resumo: The study and determination of the importance of non-genetic factors on production traits of the Nellore breed are essential to genetic evaluation programs, because they define which traits should or should not be addressed in the analysis model. There are very few descriptions of which are the traits of economical relevance to the Legal Amazon region, which provide a sign of the genetic variability present in the herds and the potential for the breeding programs. This study showed significant differences among the different States, mainly in relation to the P450 and IPP averages. The results confirmed that non-genetic factors should be taken into consideration in the analysis models for the studied traits.
