The aim of this final thesis was to create a model of the pig farm with a closed herd turnover, where the carbon balance was calculated. I counted the carbon balance based on nutrient digestibility coefficients of various feed. Thanks to the feed analyzes I found out the carbon content in feed and the feed rations. The carbon content in the slaughter pigs bodies was found through analysis of the slaughter pigs bodies. Through the analysis of digestible nutrients I discovered the carbon production in the excrement. On the model farm with 1000 sows, 27 860 piglets are born every year, 24 795 are bred and 23 542 pieces are killed. This farm consumes 7025 tons of mixtures of which 34 tons of mixture piglets prestarter (COS1) is consumed, 276 tons of mixture for piglets starter (COS2), 870 tons of mixture A1, 1655 tons of A2 mixture, 3442 tons of A3 mixture, 601 tons of KPB mixture, 63 tons of KPK mixture, 4 tons of KA mixture, 80 PCH and 1 tone of OKAS. Pigs on the farm take 2670 tons of carbon per year, 498 tons sewage in excrements and hold 648 tons of carbon in their bodies. At the same time pigs take 180 tons of nitrogen per year, sewage 33 tons of excrement and hold 77 tons of nitrogen in bodies. For the production of 1 kg of slaughter pigs on a model farm pigs need 0.24 kg of carbon and per 1 kg of edible parts it is 0.36 kg of carbon. From the above data I calculated, that pigs pollute the environment by 2.67 tons of carbon per 1 sow and 0.18 tons of nitrogen per 1 sow. This carbon can benefit plants on adjacent farms, some part may remain in the atmosphere and increase the carbon footprint.
