The present study aimed to determine the influence of the C3 component of the complement system to some production traits (live weight, reproduction, milk and fleece yield) in sheep. Experiment was done among sheep and rams belonging to four sheep breeds - Mouton Charollais, Ile de France, Trakia Merino breeds and milk crosses. For more accurate results we tested equal number of animals from each breed (48), the total number of samples was 196. The five C3 alleles (S, S5, S7, F, F1) formed seven C3 genotypes– SS, FF, FS, FS5, FS7, FF1 and F1F1, with different prevalence between the breeds. It was determined that the polymorphic C3 component of the complement system do not impact the fertility and wool production in sheep, therefore individual control and direct selection after these parameters is needed. Contrary the milk production and live weight of sheep is in close relation with some of the C3 genotypes (FS5, FS7 and SS), therefore indirect selection after these gene markers will affect positively these two production traits.
