In order to know the range in blood chemical values and enzyme activities of korean native cattle and pigs being raised in kyongbuk province, the mean values of serum protein compositions, enzyme activities(GOT, GPT, ALP), cholesterol, glucose, bilirubin, creatinine, urea nitrogen and uric acid were determined and the results obtained were as follows ; 1. Mean contents of total protein, albumin, globulin and A / G ratio for the korean native male cattle were $7.28{pm}0.86$ g / dl, 43.39{pm}0.65$ g / dl, 43.83{pm}0.92$ g / dl & 40.95{pm}0.34$；for the male pigs were 47.39{pm}0.84$ g / dl, 43.63{pm}0.43$ g / dl, 43.77{pm}0.88$ g / dl, 40.97{pm}0.26$；for the female pigs were 47.60{pm}0.68$ g/ dl, 43.54{pm}0.58$ g / dl, 43.90{pm}0.74$ g / dl, 41.02{pm}0.34. 2.$ Mean activities of GOT, GPT and ALP for the korean native male cattle were 448.3{pm}11.6$ U, 429.6{pm}4.6$ U, 413.7{pm}2.8$ U； for the male pigs were 458.6{pm}10.6$ U, 438.6{pm}5.3$ U, 424.9{pm}9.2$ U； for the female pigs were 443.9{pm}10.8$ U, 440.5{pm}4.6$ U, 413.9{pm}3.4$ U. 3. Mean contents of cholesterol, glucose and bilirubin for the korean native male cattle were 4108.7{pm}31.8$ mg / dl, 488.2{pm}26.4$ mg / dl, $0.69{pm}0.52$ mg / dl; for the male pigs were 4105.9{pm}18.3$ mg / dl, 4102.9{pm}22.3$ mg / dl, 40.70{pm}0.18$ mg / dl: for the female pigs were $113.1{pm}20.9$ mg / dl , 4103.2{pm}23.9$ mg / dl, 40.49{pm}0.21$ mg / dl. 4. Mean contents of creatinine, urea nitrogen and uric acid for the korean native male cattle were 42.86{pm}0.69$ mg / dl, $18.1{pm}5.0$ mg / dl, 41.38{pm}0.66$ mg /dl; for the male pigs were 42.20{pm}0.51$ mg / dl, $18.2{pm}4.3$ mg / dl, 40.29{pm}0.10$ mg /dl: for the female pigs were 42.36{pm}0.70$ mg / dl, $20.5{pm}5.4$ mg / dl, 40.69{pm}0.27$ mg / dl.
