Abstract :

Ruminates copper deficiency is endemic all over the world and it causes different clinical and subclinical diseases such as enzootic ataxi in lambs, decreased wool quality in sheep, cattle's falling disease , anemia, diarrhea, decreased immune system, weight loss, bones fragility …. Thus, it has a great economic importance. In order that it's important to examine deficiency of this mineral in different regions. According to that,copper deficiency is not always diagnosable in blood test, in this investigation liver sample has been taken from each sheep in four season after slaughter and the level of copper examined by atomic absorption method. In serum, copper level under 40 µg/dl categorize insever copper deficiency group, If it's 40 - 70 µg/dl places in border copper deficiency group and if it's more than 70 µg/dl, stands in normal group. Also, copper liver concentration more than 80 PPM, categorize in normal Group, if it's lower than 80PPM places in secondary copper deficiency group and if it's lower than 35PPM sits insevere copper deficiency group.  The average of copper level in serum in spring, summer, autumn, winter was 97, 123, 83, 85 mg/dl respectively and the average of liver copper concentration in these seasons was 70/69, 85/34, 74/71, 73/98 PPM respectively. The statics shows that 12% of sheep had border copper deficiency on their serums and 58 % of them had border copper deficiency on their liver and only 6%ofsheep had border copper deficiency both on their blood serum and on their liver.
