In this study, the cluster analysis method was used to examine the applicability of similar breeding policies for all districts when the statistical distribution of cattle in Samsun according to breeds was examined. The dimention reduction using PCA method was used to eliminate the variables that have no effect on the data set and to prevent the multicollinearity problem. As a result of the analysis, the explanatory power of the cluster analysis increased from 51.7% to 64.1% by using the dimention reduction. Different breeding policies should be developed for Bafra, Vezirköprü, Çarsamba and Tekkeköy districts compared to other districts, according to the results obtained by looking at the clustering graph formed when the ineffective variables are removed from the data set with the dimention reduction method. Policies for dairy cattle breeding can be proposed in these districts.}, number={1}, publisher={Iğdır Üniversitesi}
