Which factor could enhance the overall grade of goat fiber in markets?

High fineness is a critical factor that enhances the overall grade of goat fiber in the markets. Fineness refers to the diameter of the individual fibers—the finer the fiber, the higher the quality perceived by consumers and manufacturers. Fine goat fibers, such as cashmere or mohair, are sought after for their softness, warmth, and luxurious feel, making them more desirable and allowing producers to command higher prices.

This focus on fineness aligns with market demand for high-quality textile fibers, where consumers are willing to pay a premium for finer fibers that offer better performance and aesthetic appeal in garments and other products. Hence, producing goats with fine fiber aligns with both industry standards and consumer preferences, ultimately enhancing the market grade of the product.
