The aim of our research work was to investigate the breeding efficiency of the use of the German Merino local breed ram in the farm Mezkaleji. Research was made at conditions of production by forming 2 different groups of sheep depending on the used breed ram for breeding and depending on lamb month of the sheep. The sheep of the control group has been coupled with the Latvian Dark-head breed ram, but sheep of the research group with the ram of the German Merino local breed. Sheep which have been bred with the ram of the German Merino local breed showed substantially smaller number of the lambs - 1.36 per one sheep, but better growth efficiency of the average live weight of the lambs in time of twenty-four hours in period from the moment of birth to the moment of separation from mothers - 188 g. There was observable difference between live weight at birth for the single lambs and also between growth intensity of the live weight of the lambs in time of twenty-four hours - additionally larger values of the mentioned marks has been observed for lambs that were single at the birth. We can conclude that using of German Merino local breed ram the average live weight of the single lambs at birth has been for 0.5 kg smaller at age of 100 days (23.6 kg), but average live weight for twin lambs at birth is higher on 1.4 kg (21.4 kg). Theoretically calculated income from the realization of one lamb's meat of research group is for LVL 0.56 higher than in control group, but realization of twin lambs - for LVL 1.68 higher than in a control group.
