Brazil is a country where poultry technology more advanced in the last decades. The aim of this study was to correlate data from temperature and relative humidity which eggs were subjected, to the final discard data by using a multivariate analysis of the same. Data of temperature data and relative humidity were monitored. Were analyzed and classified the loss of eggs in three different days and at 14 days of incubation, the transfer of eggs from the incubator to the hatcher (18 days) and the birth of the pullets (day 21). Then we proceeded to analyze multivariate data. The results indicate an influence of thermal environment in the disposal of fertile eggs in the incubation process
