Assessment of productive actions protein sunflower oilcake and soybean products for feeding high-yielding cows is based on comparing the content of essential amino acids in the protein content of milk compared with those acids investigated feed. In the fermentation of concentrated feed at 60% amino acids lysine and methionine are becoming critical for the synthesis of milk. Bulky feeds are required for synthesis of microbial physiological function of the protein, and some of the concentrated feeds are required for stimulation of the synthesis. Soybean and sunflower oilcake must be subjected to heat treatment to reduce the cleavage of the protein in the rumen. Exponded full-fat soybean and sunflower oilcake are containing “protected” from bio-hydrogenation fatty acids in the rumen, which is a factor in increasing the fat content of milk. The high content of lysine and less content of methionine in soybean products, and conversely, a high content of methionine and less content of lysine in sunflower meal or oilcake give reason to use them in a 1:2 ratio in the diets of high-yielding cows
