ABSTRACT
Perinatal period is the most important time in the feeding of dairy cows, which affects all subsequent lactation. Very important in this period is the appropriate selection of feeds, ensuring the nutritional needs of cows. Because of the poor appetite of cows after calving, metabolic disorders often result from negative energy balance. In order to counteract this, it is necessary to administer specialized feed additives to cows for that period. This includes protein and protected fats, feed yeasts, propylene glycol, anionic salts and bolus. These preparations are designed to protect cows from falling feed intake and improve energy balance in the female body. They also increase milk yield and improve milk parameters. All this makes modern milk farms more and more used.
