The artificial insemination studies (especially after 1980) and animal improvements projects started in 1970 were the main factors effected the rapid decreasing in the number of native pure breed cattle. Especially, in Trakya region in spite of the forage and pasture areas decreased the lands for the cereal and industrial crops was increased due to intensive agriculture. This tendency had in fluoresced very much especially sheep husbandry with based on pastures, and aria of forage from many point of view. The major results was the decreasing number of native animals inside of the percentage of improved breeds in total cattle population had reached in 48–50 % in Turkey; Trakya region at this value as 93–95 %. Consequently, native sheep breeds (eq. Kivircik) and cattle breeds (eq. Bozstep) were drastically, decreased. So these mentioned farm animal breeds are about to extracted. The main aim of animal improvement was also obtaining. Genotypes with suited and equipped futures expected environmental conditions. It is logically impossible to predict future's exact features and choose breeds in advance. Animal improvement studies are mostly focused on present environmental conditions rather than future conditions. Consequently, there was no means to guess the future's variable breed among present genotypes even with low yielded. The importance of two regional farm animal breeds with danger of extinction and needs for conserving than were argued together with suggestions about them.
