Prolonged Stimulation of Wool Growth following Injections of Ox Growth Hormone

Abstract

DURING an investigation of the pituitary regulation of wool growth, various ox anterior pituitary preparations were injected into normal sheep. The sheep were individually fed a constant weighed ration, and wool growth was measured by clipping an area of 20 cm. × 20 cm. defined by tattoo lines on the midside of the body at weekly or fortnightly intervals. The wool samples were extracted to remove ether-soluble and water-soluble grease, and the oven-dry weight taken as a measure of wool growth over the period between two successive clippings.
