Since livestock account for most of Türkiye`s agricultural greenhouse gas emissions, strategies for estimating livestock emissions must be developed. Methane emissions per animal category were estimated in this study using the Intergovernmental Panel on Climate Change (IPCC) Tier 2 method for enteric and manure methane (CH₄) emissions in two sheep breeds (Akkaraman and Anatolian Merino) and three goat breeds (Hairy, Angora, Saanen) raised in Ankara province, Türkiye. Average enteric CH₄ emission factor (EF) was 9.61 kg CH₄ head^-1 yr^-1, with the highest value of 10.86 kg CH₄ head^-1 yr^-1 in Hairy goats, and lowest 8.55 kg CH₄ head^-1 yr^-1 in Anatolian Merino. Estimated gross energy (GE) was highest in Hairy goats (30.10 MJ head^-1 day^-1), and lowest in Anatolian Merino (21.73 MJ head^-1 day^-1). Average dry matter intake (DMI) was 1.40 kg DM head^-1 day^-1. The total average volatile solids (VS) excretion was estimated at 0.95 kg DM head^-1 yr^-1, and the average methane emission factor (EF) for animal manure was 0.46 kg CH4 head^-1 yr^-1. Total mean VS estimate was twice as much as the IPCC default values, and the CH4 EF for animal manure was higher than the IPCC default values. The current study's estimates will be helpful in the creation of the national methane inventory. In case more detailed data are collected to improve population data, subcategories may be expanded, and subgroups may vary by region.
