The analysis of impact that breeding area, year of birth, calving season andinteraction between breeding area and calving season have on milk and milk fatproduction in full lactations was performed in 241 Simmental cows, with 897lactations born in period from 1998 to 2007 and distributed into three breedingareas (Čačak, Zlatibor and Rudno). According to applied model, analysis of theinfluence of paragenetic factors, imapct of breeding area and interaction ofbreeding area and calving season on the production of milk and milk fat in fulllactation was very significant (P<0.01). The year of birth did not significantlyimpact (P>0.05) the production of milk and milk fat, while the calving seasonsignificantly impacted (P<0.05) the production of milk and insignificantly (P>0.05)the production of milk fat in full lactation. Coefficients of determination were verysignificant (P<0.01) and ranged from 0.431 (43.1%) in milk fat production to 0.500(50%) in milk production.
