Studied was the influence of adding to the main diet a grass meal (GM) of maral root (Rhaponticum carthamoides) at the rate of 400 or 1000 g/head/day on the digestibility of nutrients and efficiency of the use of nitrogen in the diet of milking Black-and-White holsteinized dairy cows. The physiological experiment was carried out at one of the farms of the Perm Region for 3 groups of animals, 3 heads in each. Animals with a high input rate of GM consumed more dry matter and energy feed units by 7.2%, and crude and digestible protein – by 6.6 and 4.2%. The digestibility of nutrients in their diet was higher than in the counterparts of the control group by 3.51% dry and 4.06% organic matter, crude protein by 4.3, crude fat by 2.62, crude fiber – by 3.03 and nitrogen-free extractive substances – by 2.06%, while the input rate of grass meal in the amount of 0.40 kg per head per day allowed obtaining a difference of 1.92% 0.11; 0.58; 0.89; 2.64 and 1.68%, respectively. More effective use of feed nitrogenous substances was observed in the group of animals with a high input rate of GM to the diet. With its 6.0% greater intake in the diet, daily losses with feces were higher by a similar amount, and with urine it was lower by 11.7%. With milk of cows of this group, they released more by 19.8% and deposition in the body was higher than in the counterparts of the control group by 15.1 g per day. When the rate of input of GM of 400 g per head per day the differences w
ith the control group in the consumption of nitrogenous substances and their loss with feces and milk were not reliable, but the loss with urine decreased by 7.1%. The daily average deposition in the body was higher by 7.0 g than the control group and amounted to 25.1 g. It has been concluded that feeding animals with GM especially in an amount of 1000 g/head/day positively influence the digestibility of nutrients o9f the diet and use of feed nitrogen.
