Impact of grassland saline-alkaline degradation on domestic herbivore rumen microbiota and methane emissions.

ABSTRACT:

Introduction

Grazing ruminant production has the risk of degrading the environment beyond natural recovery due to their production of enteric methane (CH₄) which is the main contributor to the increase in global CH4 emissions. In particular, grasslands are currently experiencing severe saline-alkaline degradation that is prevalent in arid and semi-arid grassland areas globally. Yet, the impact of grassland saline-alkaline degradation-induced alterations in plant resources on herbivore, and subsequent CH4 emissions, remain underexplored.

Methods

Here we examined these effects by feeding domestic ruminant-sheep with plants from undegraded (UG), moderately degraded (MG), and severely degraded grasslands (SG), focusing on rumen key microbes and nutrition process.
