Diet selection and intake of yak ( Bos grunniens ) in warm‐and cold‐season paddocks of Potentilla f ruticosa rangeland in northern Qinghai‐Tibetan Plateau

摘要

Two‐season‐rotational grazing system between warm‐and cold‐season paddocks has been spreading as accompanied by the decline in nomadism in Qinghai‐Tibetan Plateau.It was reported for this system that deterioration of vegetation was greater in warm‐season paddock than in cold‐season paddock (Li et al., 2006 ; Li et al., 2007).In this study, diet selection and intake of yak ( Bos grunniens) cows were investigated in the rangeland of northern Qinghai‐Tibetan Plateau to evaluate the two‐season‐rotational grazing system.
