Analiza uticaja odgajivačkog područja, godine rođenja, sezone telenja i interakcije odgajivačkog područja i  sezone telenja na proizvodnju mleka i mlečne masti u standardnim laktacijama izvršena je kod 241 krave simentalske rase sa 897 ostvarenih laktacija rođenih od 1998. do 2007. godine i raspoređenih na tri odgajivačka područja (Čačak, Zlatibor i Rudno). Na osnovu primenjenog modela za analizu uticaja paragenetskih faktora uticaj odgajivačkog područja i interakcije odgajivačkog područja i sezone telenja na proizvodnju mleka i mlečne masti u standardnim laktacijama bio je vrlo značajan (P<0.01). Godina rođenja i sezona telenja nisu značajno uticale (P>0.05) na proizvodnju mleka i mlečne masti, Koeficijenti determinacije bili su vrlo značajni (P<0.01) i kretali su se od 0,516 (51,6%) kod proizvodnje mlečne masti do 0,585 (58,5%) kod proizvodnje mleka.
