title: Wool proteins of New Zealand Romney sheep.
abstract: Proteins extracted from the wool of 65 Romney ewes were analysed qualitatively by one- and two-dimensional polyacrylamide gel electrophoresis. Romney wool proteins could be classified into the low-sulfur, high-sulfur, and high-tyrosine protein groups described for wool from other breeds. The wool protein pattern of an individual sheep remained constant despite changes in season, age or nutritional status of the sheep, and did not vary between different body positions. There were between-sheep differences in protein pattern, most variation occurring in the high-sulfur protein group. These differences were presumed to reflect genetic differences between the sheep.
