摘要

. In recent years, animals have evolved to feed alongside the operating conditions and economic environment of growth, so being a farmer was radically transformed. Feeding dairy cows in considered a milestone because of its economic importance, gauged by productivity in manufacturing of milk a cow gives. The paper presents a validation protocol for a UV-VIS quantitative method used to determine the amount of urea in milk, using a color complex of urea with diacetilmonoxime and tiosemicarbaside in acid medium. The parameters targeted for the validation were: specificity, linearity, detection and quantification limits, accuracy and precision. The second purpose of this method is to compare the quantity of added urea in daily ratio of Holstein breed and the content transferred in milk, in order to determine the quality of milk.
