Abstract

The present investigation was undertaken with the objective of correlating peripheral
concentration of Thyroxine (T4) and Triiodothyronine (T3) hormone with age and sex in Magra
sheep. Also, the study was aimed to correlate the peripheral concentration of thyroid hormones with
serum cholesterol during ageing. The T4 concentration decreased with the advancing age. No
definite pattern was noticed in the changes of T3 level as the age advanced. Female animal had
significantly (P0.01) higher toal T4 levels as compared to males whereas no sexual dimorphism
was observed in T3 levels. Serum cholesterol concentration increased with the advancement of age.
