Due to the harmful effects of greenhouse gases on the climate, many countries, including the Republic of Croatia, have committed to monitoring and gradually reducing greenhouse gas emissions. Livestock production as one of the significant factors of total greenhouse gas emissions is also subject to this obligation. IPCC guidelines were used for calculation and poultry production was divided in 5 categories (laying hens, broilers, turkey, geese and ducks). Methane emissions and direct and indirect nitrogen oxide emissions from manure management were calculated. Methane emissions from enteric fermentation for poultry were not calculated because it is considered that due to the specifics of their digestive system and the types of feed they are fed, methane emissions from enteric fermentation are negligible. Poultry production contributed to methane emission on average with 0, 94% and to nitrogen oxide emission on average with 21, 10%. Overall, poultry production in Croatia in the given time period emitted 1597, 75 kt CO 2eq which is 2, 51% of the total emission from livestock production and 0, 27% of the total emission of greenhouse gasses emitted in Croatia. This result shows that poultry production has a lower impact on the environment than other livestock productions, but despite that, further research is needed on improving feed digestibility and genetic predispositions of animals in order to maintain the current production while reducing greenhouse gas emissions.
