Dairy cows are also subjected to the action of various factors of influence due to the feeding peculiarities.

Observations were made on the quantity of daily milk, the milk quality and hygiene and the health of the dairy cows. We observed that at the beginning of the experiment the somatic cell contents was 800000/ml, and at the end of the experiment it decreased to 400000/ml. The quantity of milk increased between 4 and 12.5%, the fat contents decreased by 0.4 to 0.6% while the protein content was not influenced.
