Biological Significance: Seasonal weight loss caused by poor pasture availability has strong effects on wool productivity parameters and quality traits. In this work we determine that experimentally induced weight loss causes a decrease in fiber diameter associated with an increase in the level of high sulfur protein KAP13.1 and proteins from the high glycine-tyrosine protein KAP6 family. The implication of this is that decreasing the fiber diameter of the wool by this process could result in a fiber reduced prickle but with reduced wearability and appearance retention.
