Intensification of pastures in the tropics should consider Enteric Methane Emission to the environment to save the climate: An in vitro CH4 analysis from common intensified range pastures in Kenya

Livestock production in the tropics contributes significantly to climate change through enteric emissions compared to in the developed continents. This is mostly attributed to the feed quality, extensive production systems, and the husbandry practices employed in Africa. Efforts to reduce these emissions have been the call in the recent parts, with prospects in finding environmentally friendly feeding systems. The need to explore available feed resource with potential for reduced emissions and increased production is paramount in Africa. This study evaluated local intensified range grasses in Kenya in comparison to temperate feeds with regards to in vitro CH4 emissions. Varying emission levels were noted from the test grass species. Breeding could help reduced emissions as observed in Bracharia hybrid. A few local grasses species have great potential like Panicum maximum and Cecnchrus celiaris which showed lower CH4 emission, and higher digestibility compared to Bracharia and rye grass. Future breeding efforts should consider local species and select for low enteric emission potential for the benefit of our environment.
