Protein bound iodine levels during oestrus, pregnancy and non-pregnancy states in goats.

ABSTRACT

Thyroidal function in goats as estimated by PBI values of blood serum showed a very high activity in oestrus, followed by that in pregnancy state. There was significant increase in PBI values between oestrus and non-pregnancy groups. The lack of significance between pregnancy and non-pregnancy values has been explained. Mean PBI values in oestrus, pregnancy and non-pregnancy were respectively 5.91, 5.31 and 3.74 mug/100 ml blood serum.
