The article discusses the results of own studies of the authors, the literature data, and the best practices of Romanov sheep breeding. The research was performed at the two Romanov sheep pedigree breeding units in the Tver region, LLC Rassvet and LLC PF Pokrov. This breed has several advantages, such as the possibility of insemination in any season, early maturing, multiparity, the quality of sheepskin, and the taste of the lamb meat. The authors studied the productivity and the reproductive ability of ewes depending on the season, the age of insemination, the live weight, the birth type of the lamb crop. More lambs are obtained in the lambings during the autumn and winter from the ewes after three and more lambings. The survival rate is higher in the winter and summer lambings. The optimal time of insemination is 12 – 13 months. At these farms, three lambings were obtained in two years.
