The experiment has been carried out on 78 lambs of Zelaznenska sheep. Ewes and their lambs were divided into two groups. Group I during the rearing period has been kept under an umbrella roof, group II in a barn. The growth rate of lambs has been estimated and ultrasonic measurements of m.l.d. muscle and carcass quality of 20 ram lambs have been made. The results obtained showed that environmental conditions did not significantly negatively affect body weight growth, however caused an unimportant reduction of subcutaneous fat thickness and meatiness of the loin part of the lamb's body. Maintenance under the umbrella roof contributed to carcass quality improvement, which has been proved by a significantly higher lean meat content in the hind leg
