چکیده

In four sheep dosed with N-[5-(4-aminophenoxy)pentyl]phthalimide (400 mg/kg live weight) fibre growth stopped within l-ls days and the sheep were readily defleeced after 9 days. Most follicles stopped growing fibres for 12-16 days. When wool growth resumed, autoradiographic measurements indicated that it was slightly enhanced in the early regrowth due to an increase in fibre diameter. This increase did not persist and mass of wool grown, measured by clipping a defined area, was unchanged. Staple crimp frequency was unaltered following dosing. The wool harvested 3-5 weeks after dosing contained significantly more high-sulphur and less high-tyrosine proteins than pre-treatment wool; these differences did not persist to 9-11 weeks.
