Abstract

The crude protein content, amino acid content, amino acid composition of the protein, and biological value of the protein of various basic food and feed materials (wheat, barley, maize, oat, sorghum seeds, soybean, sunflower meal, rapeseed meal) was determined. It was verified by means of regression equations that the quantity of amino acids rose with increase in crude protein content, therefore the amino acid content of the basic material can be estimated based on crude protein content. It was established that the glutamic acid and lysine content of crude protein can be estimated on basis of crude protein content alone. On examination of protein amino acid composition in relation to crude protein content it was ascertained that as crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased, therefore the biological value of the protein decreased.
