| Abstract | Tibet's yaks, those hardy work animals on the roof of the world, seem to be fading away. Scientists have found that today, a normal male yak weighs some 300 kg, which is 35 per cent less than yaks in the 1950s. And a female yak now produces just 120 kg of milk a year, only 60 per cent of the average yield four decades ago. Now, worried experts are carrying out an ambitious plan to romodel China's only yak semen bank on the central Tibetan plateau. |
