Abstract

Indonesia, as an agricultural country, has a large amount of small ruminant population, which contributes a significant amount to national enteric CH4 emission. This study aimed to calculate enteric CH4 emission from small ruminants (sheep and goat) in Indonesia using Intergovernmental Panel on Climate Change (IPCC) Tier-2 method. Emission factors (EF) from the country-specific calculation in Indonesia was used in this study. The national population of sheep and goat based on production categories (weaning, yearling, and mature) were obtained from the Director-General of Livestock and Animal Health Services (DGLAH) of Indonesia. From 2016 to 2019, the enteric CH4 emission from sheep and goat increases approximately 4.36% and 1.11%, respectively, due to the increase in the animal population. On contrary, from 2019 to 2020, the enteric CH4 emission from sheep decreases 0.36%. An increase in the goat population from 2019 to 2020 leads to 3.43% increase in CH4 emission. Sheep and goat that are at production levels (mature) produce 63.49% - 54.86% of the total enteric CH4 emissions from small ruminants. Despite having a greater population, goats produce lower enteric CH4 than sheep. These results are related to the lower EF value for goats due to the indigenous feed consumed by goats in Indonesia, that contains a lot of secondary metabolites compounds. Further research is needed on how to reduce enteric CH4 emission from small ruminants in Indonesia.
