The objective of the present study was the determination of the sex of chickens in ovo with the use of hyperspectral images in Creole breeders. 100 eggs from Creole breeders were used, of which images were taken on incubation days 1, 3, 5, 7, and 10. The data analysis was carried out in the Matlab software (MATrix LABoratory) 2020a. PCA (principal component analysis) statistical tests were used, demonstrating that there are differences between the days of incubation, taking into account the centering of the mean, and Least Squares Discriminant Analysis (PLS-DA) was also performed. It was carried out to classify samples according to their sex (female-male) for each day of evaluation, 6 models were created, one for each day of evaluation, there parameters of sensitivity, specificity, precision and error rate of the best preprocessing were obtained, obtaining the best result. on day one with the highest values of sensitivity, specificity and accuracy 33,30%, 100%, 66,7% for the male class, 100%, 33%, 66,67% for the female class. To confirm the prediction of the sexing of egg samples, PLS-R (partial least squares regression) was also carried out, two preprocessing processes were analyzed for each model (MC, MC+SNV (standard normal variable)), with the highest coefficient of determination (Rp2) 0,879 indicating a good correlation, y for the reduced model (Rc2 = 0, 89). The hyperspectral images allowed the identification of sex with 66, 7% accuracy for the male class and 66,67 % for the female class on day 1.
