Cashmere goat

life science Maturity 11-13 Next article →

A cashmere goat is a specialized breed of goat used for producing cashmere. Cashmere is the fine, soft, and downy undercoat of the animal. This undercoat is highly valued for its commercial quality and quantity. While most common goats, such as dairy goats, possess a two-layered coat, cashmere breeds are specifically selected for their undercoat. This soft layer grows as the days get shorter. It exists beneath an outer layer of coarse hair called guard hair.

The growth of this fiber involves two distinct types of hair follicles. The coarse guard hair is produced by primary follicles. In contrast, the soft cashmere down is produced by secondary follicles. This biological process allows the goat to maintain its warmth. The quality of the cashmere is often measured by its diameter in microns. For example, highly productive herds can average a diameter of 15 μm.

Different breeds have developed unique characteristics based on their specific environments. The Changthangi, also known as the Pashmina goat, is found across China, Mongolia, Myanmar, Bhutan, Nepal, Pakistan, and India. These goats often have large, twisting horns and can be white, black, gray, or brown. Their fiber is exceptionally rare, representing less than 0.1% of global cashmere production. They produce an average fiber diameter between 12 and 13 μm and a length between 55 and 60 mm.

In China, several regional breeds have been developed through specific breeding programs. The Hexi cashmere goat lives in the desert and semidesert regions of Gansu Province. About 60% of these goats are white, and a typical adult doe produces 184 grams of down at 15.7 μm. The Inner Mongolia cashmere goat is a dual-purpose breed that adapts to desert pastures. This breed includes five strains: Alasan, Arbus, Erlangshan, Hanshan, and Wuzhumuqin. The first three strains focus on quality, while the last two focus on high production.

Other Chinese breeds show how selection can change a herd's productivity. The Liaoning cashmere goat was developed from animals selected in the 1960s. The Chinese Ministry of Agriculture formally named this breed in 1984. By 1994, selected Liaoning does were producing 326 grams of down at 15 μm. Breeders focus on size, body length, and the goat's ability to climb. Similarly, the Wuzhumuqin strain was recognized in 1994 after development began in 1980. In 1994, Wuzhumuqin does produced an average of 285 grams of down at 15.6 μm.

Geographic location plays a massive role in goat populations and types. In 1994, China was the largest producer of cashmere with an estimated 123 million goats. On the Tibetan Plateau, there were more than 7 million goats. This population included 5 million in the Tibet Autonomous Region and 1 million in Sichuan. In Mongolia, the Zalaa Jinst White goat is the only breed recognized by the Mongolian Wool & Cashmere Association as entirely white. This breed is adapted to nomadic herding in the Gobi Desert.

Cashmere goats belong to a group of fiber-producing animals. This group includes the Pygora goat, the Nigora goat, and the Angora goat. These animals are all utilized for the specific qualities of their hair or fleece. Understanding these breeds helps us see how humans select animals for specific traits. From the fine Pashmina of the Himalayas to the desert-adapted goats of Inner Mongolia, these animals are essential to the textile industry.
