Abstract: A number of studies have been performed on growth and development of ewe lambs of Tsigay breed and Bentheimer cross breeds at birth, and when they were 3-3.5, 6-7 and 12-13 months-old. At the age of 12-13 months, body measurements have
been done and build indexes have been calculated. Milk productivity of Tsigay ewes and ♀Tsigay х ♂Bentheimer cross breeds of first and second lactation has been measured during frst 20 days after parturition. Milk productivity is presented during milking period, and chemical composition of Tsigay sheep milk is compared with that of mixed bred ewes produced by crossing with Bentheimer rams at first lactation.
