The most critical period in the production cycle of dairy cows is the time from calving until peak of milk production. Dry matter intake, concentration of energy and proteins, structure of the feed and carbohydrate composition are the most important factors affecting milk production. Nutritional imbalances, deficiencies, or erratic management of feeding programs for dairy cows create large number of health problems and metabolic diseases. The presented system of biological control of the level of nutrition lactating cows in the farms comes from the analysis of nutritional and dietetic value of feeds. The calculated and analyzed nutritional parameters for the total mix ration are evaluated in relation to analyzed markers of ruminal fermentation, blood intermediate metabolism, milk profile test, body condition scoring in relation to the level of milk production for specific biologic phase.
