Abstract. Breeding meat sheep in a large-scale farm using Romanov breed is important to have high levels of safety of young animals and slaughter yield. The purpose of our study was to study the effect of multiple births on the safety and slaughter yield of Romanov breed rams during meat sheep farming. The study was conducted on rams obtained at different levels of multiple births from birth to slaughter  at  the  age  of  8  months.  The  study  showed  that  at the birth of a single lamb, safety by the age of 8 months reaches 100%, while the slaughter yield is at the level of 48%. Lambs born in twins show a safety level of around 93% for slaughter, while the slaughter yield is 47.44%. Under similar feeding and housing conditions lambs survival in singles was 92%, while the slaughter yield rate decreases slightly, to 46.25%. An increase in the level of multiple births of ewes significantly reduces the level of production, so rams born in quads showed an extremely low level of safety at slaughter, which amounted to 62%, while the slaughter yield also decreased to 46.28%. Breeding meat sheep using the Romanov breed, it is advisable to conduct breeding work aimed at improving the safety of the resulting young by increasing the milk productivity of mothers and a competent approach to artificial feeding of young animals from multiple lambs.
