Physiological harmony of hormones related to the thyroid gland function in cretinous sheep

Abstract

The present study showed that cretinous rams and ewes revealed an obvious elevation of TSHvalues accompanied with a declined values of both T3 and T4 from the same samples. Eachof these results revealed significant differences in probability values under 0.05 (p< 0.05)when compared with samples from normal sheep of the same species. It can be concludedthat cretinous sheep had a disturbance in thyroid physiology opened the hypothesis that it isprimary hypothyroidism type.
