Taking the local yak industry as an example, it takes about three months for artificially raised beef cattle to be sold in the general market from birth to slaughter. However, it takes three years for yaks in Gannan Tibetan area to be slaughtered because they rely entirely on natural grassland.
Animal husbandry is the leading industry in Gannan. According to the scientific grazing standard, 1 mu grassland can only supply 1 yak and 5 Tibetan sheep a year, but now there are 2 to 3 yaks and 10 to 15 Tibetan sheep in Gannan. Overgrazing leads to the decrease of soil compactness and grass yield, which destroys the original structure of grassland vegetation. The imbalance between grass and livestock leads to the deterioration of grassland ecology, which ultimately hinders the scientific development of animal husbandry in Gannan Tibetan area.
Bao said that in order to protect the grassland ecological environment, it is necessary to reduce the unit carrying capacity of grassland to a reasonable range, but "there are fewer livestock grazing, and the income of herders cannot be less." Only by deep processing and refining beef and mutton products with grassland characteristics and improving their market sales value can we reduce the number and ensure the income of herders, thus truly solving the contradiction between grassland and livestock.
