title: [Influence of age on the plasma hormonal iodine response to thyrotropin injection in young calves].
abstract: The influence of age upon the increase in plasma hormonal iodine level following an intravenous injection of bovine TSH (0.2 USP units/kg) was studied in young jersey calves. The response to TSH increased between birth and the 7th day, then decreased regularly until the end of the third month. Reasons for these variations are discussed according to some results obtained following TSH injections.
