A feeding trial was carried out on Lanksaare farm and on Polula experimental farm to study the reaction of the Estonian Native breed cows to better feeding conditions. In Lanksaare feed rations for adult trial cows were formulated according to their milk yield, and in Polula feed rations were formulated for first lactation cows by Institute of Animal Science of Estonian Agricultural University. The results of this study suggest that the milk production potential of the Estonian Native breed cows could be very good nutritional condition 6000-9000 kg/year and in good nutritional condition 5000-6000 kg/year, 4.5-5.2 % fat content and 3.5-3.8 % protein content. Consequently, the Estonian Native breed cattle are worth keeping not only for genetic diversity conservation purposes, but also for their high potential productivity.
