In this thesis, the goal was to create a model of pig farm and its load of carbon dioxide in carbon dioxide equivalent, and propose measures to reduce emissions. A model example of farm BOTPAL Inc.. We calculated so-called carbon footprint through carbon dioxide equivalent. The calculations we used values obtained from both the EU material, and specific data from the farm and attempts to institute balance 222 - Grassland. We found that the farm produce for the year 2083 including pigs and ancillary facilities will produce 3562.7 tons of carbon dioxide equivalents. CO2eq production of feed was 3460 t of nitrogen emissions caused by undigested feed - faeces urine was 3227.9 tons CO2eq and methane was 52 t CO2eq. The extra traffic - piglet heating, hot water, fuel, light, eliminates the manure was 102.47 tons CO2ekv. From this it is clear that the reduction CO2eq is the only way to reduce emissions from feces and urine. To practice means to feed this perception that we should pay more attention to the digestibility of the diet to reduce emissions from manure. Increasing the digestibility of 10% would reduce emissions by 553.4 tons of emissions CO2eq feces and urine. Ancillary activities such sites does not share in the production of carbon footprint and a reduction of 10% or 20 will bring the overall perspective of any substantial change. Production of a pig weighing 105 kg and 173 days of fattening period led to the formation of 66 kg of CO2 equivalent.
