This study was conducted in the central region of Libya to compare thyroid hormones and their binding proteins in three camels of Tunisian origin who were pregnant in the last month and were (6-8 years) old, and their calves from the moment of birth and for a period of one year. The overall mean of T₄, T₃, fT₄, and fT₃ for the calves was significantly (P<0.05) high. The concentrations of T₄, T₃, fT₄, and TBG at birth were significantly (P<0.05) high in calves. However, T₄ in summer was significantly (P<0.05) high in mothers. However, during the fall and winter, the level of T4 was significantly high (P<0.05) in calves. The T₃ concentration of calves increased significantly (P<0.05) during the spring, summer and autumn. The fT₄ concentration for the calves was significantly (P<0.05) higher during the summer, autumn and winter. Mothers' TBG was significantly (P<0.05) high during the fall and summer. T₄ increased significantly (P<0.05) in calves during month 1 and from months 5-12, while from months of 2-4 it increased significantly (P<0.05) in the mothers. T₃ concentration was generally higher in the calves than the mothers, and the significant increase (P<0.05) in calves was from 1-7 months. fT₄ in the calves was significantly (P<0.05) higher from 3-8 months. Calves' fT₃ was significantly high (P<0.05) from month 1-5 and from 8-10, while significant increase (P<0.05) was at month 9 in the mothers. TBG in the calves was significantly (P<0.05) high during the month 1, while in the mothers, it was highly significant (P<0.05) in the months 5, 6, 8, and 11.
