Soybean represent the most important protein source for poultry and swine rearing but its producing in Romania and even in Europe is at a quite low level face to demands. To obtain complete mixed fodders are recurred imports from other world countries where are cultivated different soybean sorts under different pedo-climatic conditions, fact which made that products entered on Romanian market to present a great variability regarding chemical and nutritional features. In the current paper we analysed from chemical and nutritional point of view the quality of 10 soybean lots imported from Brazil. Besides basic chemical analysis were effectuated analysis to determine content in amino acids which allow a further protein nutritional evaluation by calculating chemical indices, essential amino acidsindex, protein efficiency rate, biological value and nutritional index. Proteins’ nutritional evaluation from analysed soybean meal was realised using as etalon egg protein, amino acids requirements for swine, for broiler chickens and adult persons. Chemically speaking analysed soybean meal had values into limits imposed by literature (90.1% DM, 41.24% CP, 2.47% CF, 4% CA, 4.8% Ash and 37.59% NES). Nutritional evaluation show that analysed soybean meal lots had a good content in protein and even more, a good content in amino acids. This conclusion resulted because EAAI was 0.70, PER was 2.7 and P-BV was 70%.
