Abstract

Developments in cattle raising and the need to sidered: birth weight (BW), _20 days (W_20), weaning make herds commercially enhanced have intensified the weight (W205), yearling weight (YW) and postyearling efforts to identify animals that grow and reproduce at ear-(PW), and the reproductive ones: yearling scrotal circunlier ages. In an attempt to facilitate research, through the ference (YSC) and postyearling (PSC) and age at first compilation and analysis of results for estimated genetic calving (AFC).The average estimates for direct, maternal parameters for productive and reproductive traits in zebu and total heritability were, respectively: 0.33; 0.09 and beef breeds, 67 publications were analyzed from both Na-0.27 (BW), 0.27; 0.08 and 0.2_ (W_20), 0.28; 0._2 and tional and international journals in the fields of Animal 0.24 (WW), 0.3_; 0._0 and 0.26 (YW), 0.35; 0.05 and Science/Fishing Resources between _995 and 2005, all of 0._8 (PW). Nearly 70% of all articles were published in which are rated A or B by the QUALIS program (2005) journals rated A, with international circulation, and 78% at CAPES’s Portal. The productive traits had been con-concern the Nelore breed.
KEY WORDS: Age at first calving, genetic correlation, heritability, scrotal circumference, weights.
