Production of milk, fat, proteins, lactose, dry matter, utilizable dry matter and solids-not-fat (SNF) was evaluated in 177 lambing ewes of the Improved Wallachian breed (IW) in the course of 145-day milking period in 1993. The average output of milk per milking period was 95.3 l, 6.4 kg of fat, 4.9 kg of proteins, 4.7 kg of lactose, 16.8 kg of dry matter, 11.3 kg of utilizable dry matter and 10.4 kg SNF. There are large differences in productive indicators between the lambing ewes, which can be profited from in further breeding aimed at an increase in milk performance. The average daily milk production during the milking period was 657.3 ml over the whole period, with the content of fat 6.7 %, proteins 5.1 %, lactose 4.9 %, dry matter 17.7 and SNF 10.9 %. The lambing ewes in the third lactation had the significantly highest output of milk, proteins, lactose, dry matter and SNF (P0.05 and/or P0.001). A very close relationship (P0.001) was determined between total milk output per milking period and output of fat, protein, lactose and utilizable dry matter (r
