Abstract: The article presents the results of scientific and economic experience of determine of effectiveness of using flax and rape oilseeds passed through the press in feeding high-producing cows. Studies have established that first-calf cows, who received rape seeds in their diet, outperformed their counterparts in terms of milk productivity by 6.2% and 2.3%.
In the production of yoghurt, the duration of fermentation of milk obtained from cows which used rape seeds in ration was 3 hours 18 min, that is 37 minutes less compared to the same indicator of the control group (P≥0.95). The product obtained from the milk of the cows of the experimental group had less whey during storage. The degree of syneresis was 26.1-28.4%.
The use of flax seeds adversely affected the technological properties of milk in production of cheese. Milk was poorly folded by rennet enzyme, the clotting time was 125.7 minutes, there was 119.9 mg% of calcium content in the milk, it is low content (the standard is not less than 125 mg%), milk consumption per 1 kg of cheese was 9.1 kg (in control 8.4 kg), while the cheese was not plastic in consistency, it did not hold the shape well. The milk obtained from cows feeding with flax seeds is not recommended for production of hard cheeses.
