Romanov sheep breed was distributed in Europe more than 50 years ago. It is attracting more and more interest in Bulgaria because of its high fertility, but data on its milk productivity are scarce. The present study aims to determine the milk yield and physico-chemical composition of milk from Romanov sheep as it is the first of its kind in Bulgaria. 137 milk samples obtained from the 30th to the 120th day of lactation of 43 purebred Romanov ewes were analyzed. The average daily milk yield was 0.510 l, reaching 0.720 l as it gradually decreased during lactation. The milk yield for the studied period was 45.7 ± 3.52 l. The percentage content of milk fat increased with advancing lactation, as lactose showed insignificant changes. The protein indicator increased at the beginning, then it slowly decreased.
