This study examined market integration and the Law of One price (LOP) conditions for cattle and sheep markets in five selected provinces by using quarter data from 1371-80. For this purpose the unrestricted VAR and cointegratlon VAR models were used. Results showed that in the case of cattle, Khoozestan-Kerman, Khorasan-Isfahan and East Azarbaijan - Khorasan provinces had the same markets. In the case of sheep, all of the markets except Khoozestan and Kerman were the same. The Law of One Price condition doesnʹt hold as a king-run relationship for any of markets, either in the case of cattle or sheep.
