Abstract:

This study was carried out on Tibetan ewes which are grazing in Qinghai alpine grassland, and we made a exploration on its Standardized farming techniques. Through the research of 4 different model of production, the result showed that: for the model Ⅰ and model Ⅱ, the lamb birth weight、two months’ weight and daily gain in the age of two months had a significant difference (P < 0.01); the lambing rate of ewes and the survival rate of lambs of the model Ⅰand Ⅱ were higher than the model Ⅲ and Ⅳ,there was a significant difference; the unit profit of ewe lambing of the model Ⅰand Ⅱ were obviously higher than the model Ⅲ and Ⅳ，achieving the purpose of increasing the famers’income、Reducing carrying capacity and protecting grassland ecosystem. Finally we got a “protecting grassland ecosystem and increasing farm’incom” win-win model of production in plateau Tibetan ewes.
