For the first time, in the conditions of the Magadan Region, studies were carried out on the use of a feed additive (FA) prepared from dwarf pine (mountainpine) in combination with lichens in feeding young cattle of the Holstein breed and crossbred young animals of the Golstein and Hereford breeds. Over the period of the experiment, the absolute increase of the experimental bulls exceeded the indicators of the control groups: young Holstein breed by 2.15 kg (0.58%), hybrids by 6.35 kg (1.51%). The relative growth rate of experimental bulls according to Brody was higher than that of bulls in the control groups: bulls of the Holstein breed by 0.12%, crossbreeds by 0.77%. The use of crossing low-productivity dairy cattle with bulls of meat breeds makes it possible to obtain interbred hybrid animals of the I and II generations. The production of beef from crossbred young stock is characterized by greater economic efficiency in comparison with the fattening of super-renovated young Holstein breed. In the experimental group of a hybrid of the Holstein and Hereford breeds of the 1st generation, this indicator was 7.2 energy feed units (EFU), which is 7.7% lower than in the control one, and 13.25% lower than in the experimental group of the Holstein breed.
