PREDIÇÃO DE PESOS E RENDIMENTOS COM USO DE DESCRITORES DE FORMA DE IMAGENS IN VIVO DE CORDEIROS

The aim of this study was to predict quantitative carcass characteristics using images shape descriptors in vivo. The experiment was carried out at the Federal Institute of Pará, Castanhal. Data from 64 male lambs were used. The variables used were images descriptors obtained through Video Image Analysis (VIA) of the dorsal view, totaling 20 descriptors, The set was submitted to the elastic net method, the results shows that was possible to predict weights and yields using images informations of live animals.
