A system for harvesting wool, in which sheep are injected with recombinant epidermal growth factor (EGF). This causes a natural disruption of hair growth, allowing the wool to be slid, glove like, from the sheep 4 weeks after the injection. The system is used primarily for Merino sheep in which the wool grows 24/7, in contrast to other breeds that do not have year-round growth of wool.
