Abstract: A study on the fattening ability of lambs of the Bulgarian Dairy Synthetic Population (BDSP) and F1 crossbreds with Chios was carried out on Agricultural Institute - Shumen. For the aims of the study, a scientific field trial with two groups of 14 lambs each was conducted under the following scheme: group I - 50-percent-blood crossbreds of BDSP with Chios; group II - purebred BDSP lambs. The study established that, according to the (S)EUROP system, the carcasses of the F1 crossbreds and of the purebreds are classified as "light carcasses" belonging to grade C. They have light-pink meat, low to medium fat distribution and satisfy the (S)EUROP requirements for first-grade quality of the light carcasses. The physicochemical composition of the meat is stable and does not suggest variation in meat quality in both groups.
BDSP and its crossbreds with Chios can produce carcasses satisfying the requirements for first quality of C2 and C3 grade according to the (S)EUROP scale for classification of carcasses up to 13.0 kg.
