Abstract. The survey covers 140 clinically healthy sheep from two indigenous sheep breeds – Karakachan (KK)and Copper-Red Shumen (CRS) over one year old. Blood samples are taken from v. jugularis, and using a semi-automatic biochemical analyzer were determined in serum levels of blood sugar, total serum protein and albumin, creatinine, urea, calcium, inorganic phosphorus and magnesium. The results obtained indicated that the levels of total protein (75.81±7.03 for KK and 72.19±5.64 for CRS), albumin (44.85±6.43 for KK and 42.09±4.06 for CRS), creatinine (183.35±291.77 for KK and 128.30±45.70 for CRS) and urea (9.30±3.90 for KK and 11.10±5.76 for CRS) in Karakachan breed are poorly higher than those of the Copper – Red Shumen. The values of blood sugar (2.89±0.49 for KK and 2.49±0.57 for CRS), calcium (2.30±0.41 for KK and 2.22±0.33 for CRS), inorganic phosphorus (1.94±0.64 for KK and 1.94±0.44 for CRS) and magnesium (1.23±0.29 for KK and 1.14±0.20 for CRS) showed no breed differences. The significant differences between the two breeds were obtained only in value of both creatinine and blood sugar.
