Summary : The serum lysozyme concentrations and the alternative pathway complement activity (ACPA) were explored in 10 local Bulgarian sheep breeds. For that, serum samples were collected from 20 sheep of each studied breed (Karakachan, Tsigay, Replyan, Panagyurishte, Copper-red Shoumen, Karnobat, Pleven Blackhead, White Maritsa, Patch-faced Maritsa and Stara Zagora) and the serum lysozyme concentrations and ACPA were measured according previously described methods. Strong breed-related differences in serum lysozyme concentrations were evidenced, values ranging from 0.109 ± 0.016 mg/L in White Maritsa sheep to 1.104 ± 0.496 mg/L in Replyan sheep (P < 0.01). Complement activity also varied according to the breed, but variations were more reduced: the highest activity was determined in the Panagyurishte breed (218.801 ± 3.285 CH50) and the lowest in the Tsigay breed (167.144 ± 5.233 CH50) (P < 0.01). The 2 parameters were significantly positively correlated only in the Tsigay breed. These results demonstrate that the serum lysozyme concentration and the complement activity were partially determined by the breed in sheep.
