    Trace elements in animal feeding are the most popular research topics in Veterinary Science. Copper has many important biological functions and the levels of copper in body fluids are affected by different factors such as seasons, breeds and some ions. In this study five different breeds of English sheep, 56 Dorset, 32 Hampshire, 25 Lincoln, 18 Blackface, ll Border, total 142 sheep were used as research materials. Blood samples were taken and plasma were separated. The plasma copper analysis were done by Atomic Absorption Spectrophotometer. The amount of average plasma copper were; % 52.80 mcg, % 51.90 mcg, % 48.08 mcg, % 46.6 mcg and % 53.05 mcg for Dorset, Hampshire, Lincoln, Gennan Blackface and Border, respectively. Obtained values were low when they were compared with Turkish native sheep breeds. This study was the one of tlıe pioneer research for these genotypes in our country.
