C.  aGenetic-quantitative analysis for reproductive traits in Nellor cattle selected for sexual precocity.h[electronic resource]  c2020  aThe selection of animals for sexual precocity and reproductive efficiency is a trend to reduce the production cycle, promote higher economic viability to the system, increase selection intensity and higher genetic gain, as well to promote the profitability of production systems. To include these traits as selection criterion in cattle breeding programs, estimating genetic parameters and studying the possibility of obtaining genetic gains is required. The hypothesis tested was that the indicators of sexual precocity traits present genetic variance and moderate heritability that allows these to be used as a criterion of selection to obtain improvement for sexual precocity, without negative implications for the reproductive efficiency in Nellore cattle.  aPuberty  aReproductive efficiency  aZebu  aGado Zebu  aReprodução Animal  aAge at first calving  aGenetic parameters1 aBALDI, F.1 aCOSTA, M.
