The effect of vitamin E and selenium on serum injection on serumic levels of T3 and T4 hormones in the Arabian horse

Abstract

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
