Abstract


In two experiments at three experimental groups(each n=9 cows) the supplement of protein through extracted soja and AMINOTEK were observed. Average daily milk yield depend on month after calving. (1st x= 28  s´=20,2, 2nd x=35 s=25,6, 3nd x=31 s=26,8).

The differences among basic milk nutriments were not statistical significant during experiment. The contents of milk nutriments were decreased at the control group and at the both experiment groups in January. A tendency to higher level of proteins, methionine and cystine  was at the experiment groups. The content of lysine is constant. We observed increase content of oil acid in milk tested dairy cow. These dairy cows were fed by AMINOTEK suplement. The oil acid could be basic component in another non-saturated acid in milk fat (NNKT). Again was find higher delegacy linol acid.
