50 lambs were obtained from crossing North East Bulgarian fine-wooled ewes with Askanian, German Mutton Merino and Danube Merino rams. Intensity of wool growth reached its peak at 4, 8 and 16 mth of age; fibre diameter varied from 22.35 to 23.67 micro at 2 mth of age and from 21.10 to 23.93 micro at 15 mth; staple length varied from 2.7 to 6.7 cm at 2 mth of age and from 3.7 to 6.3 cm at 16 mth of age. Body weight rose from 22.4-25.7 kg at 2 mth to 54.5-65.0 kg at 16 mth of age.
