通过选择育种降低绵羊甲烷排放的研究进展

羊等反刍家畜是全球温室效应气体的重要贡献者,如何降低温室效应气体、尤其甲烷排放量已是畜牧业进一步发展面临的挑战之一。目前已提出许多减缓家畜甲烷排放的方法,而选择育种策略以其能形成持久、可累积的改变以及相对低的成本,成为主要候选方法。本文主要对利用选择育种方法降低羊甲烷排放量的相关研究进行综述,以便为今后该领域进一步的研究提供借鉴。

Research on Reducing Methane Emissions by Optimizing Breeding in Sheep

Ruminants,especially sheep and goat,contribute to the total green house gas(GAS).How to reduce GAS emission,especially methane emission,has become one of the important challenges to further develop animal husbandry.Presently,a number of different strategies have been tested to reduce methane emissions in livestock,however,the optimizing breeding has become the priority option due to its permanent and cumulative changes as well as its relatively low cost.In this paper,relevant research on reducing methane emissions by optimizing breeding was introduced to provide reference for further study in this field.
