A study on serum concentration of selenium, zinc and copper in calves with diarrhea in Shahrekord district

Diarrhea is the primary cause of deaths in the immune incompetent neonatal calves. On the other hand، a functional immune system requires nutrient (such as; energy، proteins، minerals and vitamin A، D and E) inputs for cellular production and maintenance. The interaction between efficient immune system and measure pathogens that cause diarrhea is very important. To this reason and to determine the mineral changes during diarrhea، selenium، zinc and copper concentration in serum were measured by Potentiometric Stripping Analaysis (PSA) and Constant Current Stripping Analysis (CCSA) methods in 35 healthy and 35 calves with diarrhea. Results indicated that serum concentration of copper in diarrheic calves was significantly lower than that healthy ones (P<0. 05). This finding may describe the copper role on preventing and treatment of diarrhea.
