Thyroxine (T4) and triiodothyronine (T3) in female camels and cows

Abstract

Thirteen lactating dairy cows from Al-Fateh University Farm and 25 female camel (Camelus drotnedarius) from Tripoli abattoir were used in the experiment. Blood samples were taken from cows via tail vein puncture using vacutainer needles. Blood samples from camels were collected during slaughtering at the abattoir. Thyroxine (T4) and Triiodothyronine (T3) concentrations were measured in all blood samples using reliable radioimmunoassay procedures (RIA). The results showed that camels have significantly higher plasma concentrations of T4 and T3 than cows.
