Abstract

The Qinghai-Plateau, characterized by an extremely harsh environment, namely, severe cold, low air oxygen content and strong ultraviolet radiation, accounts for one-third of the total grasslands in China. Yaks (Poephagus grunniens) have adapted well, both physiologically and anatomically, to the high altitude and extreme cold. They are vital for the livelihoods of the herders, providing milk and meat for consumption, dung for fuel, fertilizer and building material and fiber for clothing, tent material and rope. It is estimated that, on an annual basis, each lactating female yak produces an average of 288 kg milk, 19 kg butter, 17 kg hard dried curds (qula) and 84 kg yoghurt and each yak produces an average of 786 kg of dung organic dry matter. This paper discusses the importance of milk and dung production by yaks for the livelihood of the herders and the role of these products in carbon recycling.
