Herd size ranged from 80 to 130 cows main herd. The duration of the grazing period in the three herds over 340 days.The investigation is based on accounting information farm. The aim of the study was to establish the influence type of mating on the economic indicators in meat-herds. All results were statistically processed in the middle of the software product Excel in the estimate of an animal. It is established that when applying the random mating demonstrated small number of weaning calves (P <0.05). Highest income per cow have occurred by fertilization by hand (P <0.01). Profit from cow produced by fertilization by hand been demonstrated in P<0.01 compared to artificial insemination.
