A total of 929 serum samples were randomly collected among domestic cattle from 8 provinces in northern, northeastern, central and southern parts of Thailand. Analyzing of copper concentration in sera of these cattle was carried out by Atomic Absorption spectrophotometry which showed the value at the average of 57.6+-16.6 micro g/dl (the range of concentration is 0-132 micro g/dl). Some provinces e.g.: Pathumthani showed very low value on an average of 31.5+-18.7 micro g/dl (4-78 micro g./dl) and the other provinces also showed lower average values of 47.7+-17.5 micro g/dl (Supanburi) to 71.9+-18.3 micro g/dl (Songkhla) comared with a normal range of 80-120 micro g/dl in mammals (Underwood, 1977). There is no significant difference between male and female cattle. But, there are significant differences between serum and plasma and the age of 1 year old and 1 year old. Lastly, there is a significant difference between mother cattle and their calves in a group of these cattle.
