             This study was conducted evaluate the effect of vitamin E and Selenium injection on serumic levels of thyroid hormones in the Arabian horse. Twelve Arabian stallions of approximately equal age were selected and based on their age (4 and 5 years old), allocated to tow groups each consisting of six animals. In each group, three of the six horses were injected by vitamins E and selenium at a dose rate of 1cc/30 kg intramuscularly every tow days and the other three animals which were chosen as the controls were similarly injected by normal saline solution. Two days alter each injection; blood samples of the horses in each group were collected using venoject from the jugular vein. After separating the blood serum by centrifuging, the levels of T3 and T4 were measured using the ELISA technique. Following the first injection, the serumic levels of thyroid hormones demonstrated a significant increase in comparison with the controls (p<0.05) while after the second injection, the serumic levels of T3 and T4 had decreased to normal values similar to the control groups. However, following the third injection the decreased in T3 and T4 levels was clearly evident and statistically significant (p<0.05). According to the results of the present study, the injection of vitamin E and selenium for more than twice leads to decrease in the seumic levels of T3 and T4 hormones of the horse and this is coupled with reduction of the basic body metabolism which is not beneficial for the animal.

        This study was performed to evaluate the effect of vitamin E and Selenium injection on serumic levels of albumin, protein, calcium, phosphorous, alkaline phosphates, alaninamonitransferas and aspartataminotransferas in the Arabian stallions. In this study 12 Arabian horses were selected in 2 groups of 4 and 5 years old. In each group, horses were allocated to two sub groups of controls and treatment, each of them containing three animals. In the treatment group, 1cc/30 kg vitamin E and selenium was injected intramuscularly in 2 day intervals for 6 days, while in the control group the same amounts of normal saline (0.9%) was injected. Blood samples of all animals were collected from the jugular vein at days 2, 4 and 6 and their sera were harvested by centrifuging and the levels of the parameters were measured using commercial kits and the spectrophotometric method. The results of this study indicated that there was no significant difference on mean serumic albumin, phosphorous, alkaline phosphates, alaninamonitransferas, and spartataminotransferas in the studied animals while mean serumic protein values of 4 year old horses indicated a significant difference following the third vit E – Selenium injection (p<0.05). The levels of calcium showed a significant difference following the second injection in 4 and 5 years old horses (p<0.05). Based on the results, it can be concluded that vit E – Selenium injection could be beneficial for horses without having any side effects on the liver and kidney but alterations of other biochemical and hematologic parameters should also be investigated.  Manuscript profile
